Not many people are informed about what lung cancer means and it has not given many attention to this kind of cancer by the mass media or the public although is one of the roughest disease of our generations that kills many people each year and more and more people are being diagnosed with this kind of illness
<-336x280 Large Rectangle - center->
It is not know that the majority of the people which are diagnosed with lung cancer disease meaning a percentage of over 80 per cent of the total number actually die each year because the disease is too rough and they can not resist it . Of course, this type of cancer that kills more people than many other more known and about which the mass media usually talks, has some causes which are the external factors of the cancer and also there are causes which can vary from person to person, from organism to organism and even from cancer to cancer because they can have different evolutions

The external facts are about the prognosis that the doctors give and also about the staging of the disease . If people want to have information about lung cancer, they should try to ask the doctors to explain them the facts about the disease and its characteristic, progression, survival rates, prevention, causes, effects, complications or start to read on the internet, to search for book which have related articles, chapters about this matter .

The majority of the people when are diagnosed with lung cancer usually are in advanced stages when the things get more complicated and this sort of thing happens especially because the symptoms in early stages many times do no show up or they are easily confounded with a simple flu and they do not pay any attention to it . But as the time passes and it starts to progress the cancer starts to spread towards the lymph nodes and many other parts and implicit organs of the body and it is no longer just local it become in some way general at the level of the organism .

As things get more advanced there appear all sorts of complications which make the doctors’ tasks more difficult because the treatment that can be applied is no longer such easily because surgery can interfere only when the tumor is localized in a place where the intervention is possible, chemotherapy and radiation therapy may not give proper results and can also have side effects .

The survival rate of patients in advanced stages of lung cancer are no longer very optimistic and they can not even be in the five year life expectancy that the doctors predict the moment when the cancer is discovered and diagnosed . Information about lung cancer is extremely much and it is essential to know it in order to be able to understand the effects and the cause of the disease and to understand that it can be pretty simple avoided if you know the prevention means .

Lung cancer is known as any type of cancer a deadly and serious disease but what most of the people do not know and would not even guess that lung cancer is the type of cancer which actually kills more people per year than all the other types of cancer because the number of patients killed by this disease is over 1 million each year and it is still rising .
<-336x280 Large Rectangle - center->
The number of people diagnosed with lung cancer is somewhere circa 1,3 millions people and they are all given when they are diagnosed with lung cancer a five year survival time but if they will actually manage to live after 5 years, it depends on many and several factors which all play important roles in the patient’s life .

First of all it is important to know that life expectancy in lung cancer patients differs very much from patient to patient and also it depends huge on the type of lung cancer . Lung cancers are divided in two parts, classification which is made by the way the cells from the tumors are seen at the microscope. The first category is the small cell lung cancers and the second one non small cell lung cancers

The first category does not occur pretty often, it is rare developed by humans and the life expectancy usually is of 5 years especially when the tumors are found in the first stage when the tumors are not in extended stage . Non small cells lung cancers are the most frequent cases of lung cancer and they are divided in some sub categories but apart for the rare giant or large cell lung cancers which are extremely rapidly fatal to the patients, all the other type can actually manage to have the life expectancy of five years in different percentages which are influenced by other causes

It is important to know the fact that the stage in which the lung cancer is discovered is extremely important because for the first two stages the prognosis are much more optimistic because at that moment the tumors are local in the lungs, they did not spread to other parts of the body and patients can be helped with various types of treatments : surgery for trying to remove the tumor, if it is localized in an area where the intervention it is possible and also chemotherapy and radiation therapy can be used to help the patient to recover

For the advanced stages meaning stage 3 and stage 4 the things are more complicated because the tumors are no longer just local and they started to spread ; they have reached the lymph nodes close to the tumors place or even situated at certain distances and also they have started to affect other parts of the body and implicit other organs which may be vital for the life of patients . Life expectancy in lung cancer patients in these cases are not so high because the complications develop too quick and affect other vital functions of the patient .

Lung cancer is known as one of the severest cases of cancer because the mortality rate is extremely big meaning that a percentage of 85 or 90 per cent of the total people who are diagnosed with lung cancer die till the end of the five year survival rate which they are given the moment when they are diagnosed so a number of over one million people die each year killed by this terrible disease which does not show any mercy .

Other major problem of this disease are the various and multiple complications that people with this disease develop many complications .There can be fluid in the lungs and this has many further effects on the body because with the help of the fluid the cancer can spread to other parts of the body and it can affect healthy cells . And many complications occur and it is important for patients to know what happens when lung cancer spreads .

The first and most common effect are : disturbances of hormones , blood or other systems can be harmed but these can also occur as side effects of the applied treatments ; but those effect are only the beginning because new health problems will develop and there will be affected organs like : liver , brains and bone cancer .

Metastasis to the bones is one usual effect of cancer on body in advanced stages but also can happen when the lung tumors develop small cancer cells . Metastasis to bones is felt by bone pains , usually in the backbone , thighbones and ribs . Other step of the progression of the disease is when lung metastatic cancer affects the brain . Cancer gives many difficulties to the patients and they can have problems : vision , weakness on one side of the body or even both and it can also affect seizures .

The lung cancer can also spread to thyroid and give many hormones problem and can also reach the heart . The fluid full of cancerous cells can gradually develop in the space between the lungs and the chest wall , which is called pleural effusions .Then there is little oxygen left in the lungs and the levels drop very low and the patient can not breath and this is followed by heart problems because the right side of the heart grows too much and reaches great sized and it can lead to heart failure or pulmonary hypertension and it can end with the death of the patient .

As you can see what happens when lung cancer spreads on body it is very rough . The patient has to deal with the problems of the lung cancer and its treatment but also he has to be applied a treatment for healing lung cancer and also for preventing the other side effects or to try to minimize them at a minimum level . The survival rate of lung cancer is small but associated with this kind of effects it is even smaller .

Lung cancer kills annually more than 1.18 million people this means that a percentage of over 85 or 90 per cent of the total people who are diagnosed with this type of disease eventually die . What is more curios is that over 90% of the total numbers of deaths is caused by smoking but it has also other causes such as : radon gas , asbestos , viruses , particulate matter but all this causes together do not cause more than 10 per cent of the total number of diagnosed people but also by the total number of deaths cause by this type of cancer .
<-336x280 Large Rectangle - center->
The numbers are so cruel because the majority of patients are diagnosed when they are already in advanced stages of cancer and the treatment can not have so many effects and the five year survival rate is poorer .

Other major issue about this type of cancer is the fact that patients who suffer of this disease often develop many other complications of other parts and organs of the body . So the patient can experience : disturbances of hormones , blood or other systems can be harmed and also lung cancer often can affect the liver , the adrenal glands , the bones or the brain ; these affections can be side effects of the treatments which were applied to the patients or as complications of the cancer when it is metastatic

More effects occur when lung ,metastatic cancer affects the brain .So if lung cancer metastasized to brain , the complications which appear are grave and cause the patient many existential problems : vision , weakness on one side of the body or even both and it can also affect seizures .

But this is not all because many other complications may occur if the lung cancer is metastatic and it can affect many other parts of the body . If the patient develop metastatic cancer , it is important to point out that it usually affects the liver , but it does not cause symptoms . The same problem occurs also when the cancer affects the adrenal glands .

Metastasis to the bones is one of effects of cancer on body especially in advances fazes of the cancer when the tumors develop small cancer cells . In this case the patient experiences pains , usually in the backbone , thighbones and ribs . Other type of complication it is caused when there is fluid in the lungs because the level of oxygen in blood drop and it leads to shortness of breath , the right side of the heart enlarges and it can lead to a possible heart failure which is called by doctors as pulmonary hypertension .

Fluid on heart and lung cancer metastasized to brain are one of the most deadly complications that can occur if there appear delays in diagnosing the lung cancer of delays in treatment because the lung cancer easily spreads and can cause a terrible death .

Non small cell lung cancers have four different stages from I to IV meaning the fact that stage I is the one which is an easier stage and IV stage the most severe of all . In stage I , lung cancer is at the beginning and is confined to the lung .The patients who are diagnosed with stages II and III , the cancer is already confined to the chest and we can already speak about large tumors , the stag is classified as a advanced stage and that is in most cases a patient who is diagnosed with stage III lung cancer . If we refer to stage IV , the lung cancer is extremely spread to all parts of the body and is metastatic and we can even call it end stage lung cancer .
<-336x280 Large Rectangle - center->
Life expectancy in this final stage is considered extremely poor or even zero but this can vary among different kinds of bodies and patients . One important factor is the type of lung cancer, where it is localized because in this stage the cancer encompasses few types of cancers and cancers which have spread to only one region or cancers which have spread throughout the body .

Other important factors are also the age, younger patients can manage to live longer than the older patients , also the sex is a major factor because the life expectancy for women with lung cancer is much more higher at any stage of lung cancer than the one for men , general health of the patient because a good general health can help the patient to have a longer life expectancy, can give the patient a greater ability to bear a wide selection of treatments that can improve their life quality .

How the patients feels and how healthy is he in stage 4 depends very much on how has the patients responded to the treatment meaning how their organism has reacted to chemotherapy and which side effects appeared as a result of the treatment, also how radiation therapy has worked for the patients and how many complications of the lung cancer has the patient developed in different parts and vital organs of the body .

End stage lung cancer or stage 4 lung cancer can have different life expectancies but the statistics point out that the median stage of the lung cancer meaning the time when half of the patients are alive and the other half is dead is about 8 months .

That five year survival rate that the patients are given when they are diagnosed is about the percentage of the total patients that have a chance to be alive after 5 years since the moment they are diagnosed with this stage 4 of lung cancer is only about 10 per cent . It is important to outline that this stage can not be cured but it can be treated in order to improve the survival rate but also the symptoms of the lung cancer including patient’s life expectancy .

Lung cancer is very often deadly for the patients who are diagnosed with lung cancer so the majority of the patients almost 85 or 90 per cent from the total number which are diagnosed with lung cancer disease, die till the end of the five years survival rate which they are given the moment they are diagnosed .
<-336x280 Large Rectangle - center->
Mostly this happens at the patients who are diagnosed with advanced stages of lung cancer because the cancer is metastatic, has spread to other parts of the body, has affected other organs and there appeared complications and also because the variety of treatment that can be applied is more restrained .

If we talk about early stages, things may look a little bit more optimistic . So let’s take an early faze but no the first faze of lung cancer meaning stage 2 lung cancer . This stage is also a localized cancer as the other types but the definition is a little more different . In this stage there is a lung tumor but the cancer may or may have not spread to the lymph nodes but the only thing sure is that the lung cancer have not spread to other parts of the body, and this is extremely important.

The patients who are diagnosed with this stage represent only about 30 per cent of the cancer cases but their prognosis for life is certainly much more better than the prognosis for the advanced stages meaning stage 3a or 3b, stage 4 is obvious the gravest case . When we talk about stage 2 lung cancer , we also speak about the lung tumors wich are greater than 3 cm and are developed and localized in the region of the main bronchus or they may also be found in a zone where they invade the lining of the lungs which is named pleura .

There can be also made a classification or better said a division of the stage 2 into two stages such as : stage 2a which is about the tumors that have sizes under 3 cm but the cancer has spread to the lymph nodes and also stage 2b which means that the tumors are bigger than 3 cm and they have spread to the lymph nodes or they are localized in the space nearby the main bronchus or they are localized in the lung lining or pleura .

Both fazes which are included in stage 2 have the following symptoms : persistent and rough cough and also coughing up blood is also possible , there is also a shortness of breath, the patient can develop many repeated infections such as pneumonia or bronchitis , and also there can occur pains in the chest area , in the back zone, but such symptoms which can be found in other advances stage such as weight loss and a feeling of tiredness can not be developed . The treatment for this stage are : surgery , adjuvant chemotherapy , radiation therapy .

Lung cancer is a rough disease which is responsible for killing over 1,1 millions people that represent more than 85 per cent of the total patients which are diagnosed each year with this illness . Lung cancer is hardly detected in early stages and when the majority of patients are diagnosed with it they are usually in advanced stages when lung cancer progression is already advanced
<-336x280 Large Rectangle - center->
The treatments that can be applied in most cases are relied only on surgery, chemotherapy or radiation therapy and these can happen only if the lung tumor is localized in places where surgery is possible and it can depend on the areas where the cancer has spread and also what parts of the body are affected by the cancer and especially what organs are being affected by the disease .

Lung cancer progression refers mostly at the affections and complications that can occur as results and effect of the cancer and also of the spread of the cells . patient . Unfortunately , there are many effects of lung cancer on the body of the patient and they can be multiple and hard to bear .

Sometimes the patient can develop fluid in the lung cavity and this can prove to be a just the beginning of many complications because this has another effect on body because cancer can spread to other parts of the body and healthy cells which are found in tissues and organs can become infected with carcinogens.

The main effects which can result from the spread of cancer : there can occur disturbances of hormones , many systems blood or cardiovascular, digestive systems can be harmed and except of these, it can also appear effects which are called side effects or second effects which can depend on the type of the treatment applied , or to the type of cancer if there are small cell lung cancers or non small cell lung cancers or whether the lung cancer is metastatic or not . If it the lung cancer proves to be metastatic and cancer often can affect the liver , the adrenal glands , the bones or the brain .

If the cancer spreads to the brain and affects it , the effects do not wait long before appearing so the patients start to have problems with : vision , weakness on one side of the body or even both and it can also affect seizures and there can also occur effects such as bone pains , usually in the backbone , thighbones and ribs . One of the most sever effects can happen when the level of oxygen drops there is a large lack of oxygen and the dimensions of heart can enlarge extremely much and there can be caused a heart failure .

All the effects and how lung cancer evolve , make the quality life of the patients who suffer of this lung cancer extremely poor because they develop many complications and affections of vital organs of the body .

It is important to know that there are several types of lung cancer and they are divided into the major two categories which are the small cell lung cancers or short SCLC and non small cell lung cancesr or short NSCLC ; this classification is made on the fact that when the tumor cells appear on the microscopic view are differentiated into small and non small . They are also differentiated by the way they grow and spread and because the treatment that can be applied to the patient is also different
<-336x280 Large Rectangle - center->
Small cell lung cancers appear pretty rare , they register only 20% of the total cases but they are much more aggressive than the NSCLC . Other important fact is that the small cells cancers spread more quickly and they become metastatic at short time after it affects the body and it may affect many parts of the body so there appear many and multiple complications

The non small cell lung cancers are much more frequent and they appear under many forms of non small cells such as : adenocarcinomas are the most frequent and they cover almost 50% of the cases of lung cancers, other forms are squamous cell carcinomas appear in circa 30% of the cases and large cell carcinomas or undifferentiated carcinomas are the rarest type of lung cancer cells .

Adenocarcinoma lung cancer definition is that this lung cancer is a non small cell type that is developed on the outer edge of the lung and it is localized under the lining membrane of the bronchi and it may spread to other parts of the body and it can affect many organs and if there appear delays in treatment it can easily affect the brain .

The symptoms of adenocarcinoma are very similar to the usual forms of lung cancer and their symptoms so the patients have the following symptoms : wheezing, hoarsness and shortness of breath , the cough is persistent and rough and they can even cough up blood, the patient will breath and swallow very hard, will experience many pains of the bone system and especially chest pain but also the weight loss .

The main cause of adenocarcinoma lung cancer is the growth of cell which form a tumor and by the time passes and the tumor grows larger and larger it can reach a point when the tumor will destroy many areas of the lungs and then it will be followed by the spread of the cells in all parts of the body and it is one of the most common types of cancer and it is in most cases developed by the people that smoke or stay near the people who smoke and they become passive smokers but also a little number of people can develop this disease if they expose to radon gas or asbestos .

There exists treatment for it but it depends on the place where the tumor is localized and where the cells have spread and in some cases the tumors can be removed if the patients are submitted to surgery .

Each year more than 1,3 millions people are diagnosed with lung cancer and over 1,1 millions actually die per year because they are killed of this disease . The death rate is high because it is hard to detect lung cancer in early stages and after lung cancer reaches advanced stages there appear many complications because the cancer spreads and there starts to develop many kinds of affections of organs of the patient’s body and some of them are even affections of other vital organs as well as the lungs .
<-336x280 Large Rectangle - center->
More over 90% of the total cases which are detected each year are caused by smoking because it has been proven that smokers have bigger chances to be diagnosed with this disease than non-smokers ; the risk to develop this lung affection is almost double among the smokers .

The smoking includes some factors that are tight connected with the risk of developing lung cancer and they are : the number of cigarettes smoked per day by a person and also another major factor represents the period of time that a person has been smoking . It is important to point out that smoking , indeed, is not the only cause for the appearance of this disease but it is the most frequent . Other lung cancer’s causes are : asbestos , viruses , particulate matter but also radon cause, which can be considered the second major cause of lung cancer but all these causes together do not cause more than 10% of the total cases of lung cancer that are discovered each year .

Lung cancer prevention is concentrated in only one area and this is the smoking area . Doctors and many non governmental organizations have made many campaigns that outline the danger that people who smoke expose to . The main mean for lung cancer prevention is quitting smoking for those who already smoke and for non smokers not to say near the ones who do smoke because they become passive smokers which is as grave as smoking and also not to begin smoking . Only in these ways, there will be reduced the risks of getting lung caner .

Even for those you do smoke for some time, quitting smoking is the only chance for ameliorating things . When a persons stops to inhale the bad substances which cigarettes contain, the lung tissues can start to recover . In time, gradually and step by step, the harm that has been done to the lungs starts to heal and they can have after some time the lungs recovered in a very high percentage .
Although so many campaigns have been carried out for reducing the number of smokers and to prevent non smokers to start smoking, there has been registered not so many results because many of the smokers prefer to close their eyes, to ignore and to pretend that there does no exists such many risks if they continue smoking and they think that lung cancer can not happen to them .

Annually people all over the world die because of the lung cancer and the number of death per year has reached over 1,1 ,millions patients and the main reasons for this are : the advanced stages in which the patients are diagnosed with this disease, the poor survival rate that they are given and the little number of patients who manage to survive all the life expectancy period, the numbers not so large of treatments that can be applied and also the wide range of complications that can develop as effects of the lung tumors .
<-336x280 Large Rectangle - center->
For small cell lung cancers, there is one advanced stage and that is the extended stage but only 20% of the patients are diagnosed with this type of lung cancer . The majority of patients are diagnosed with different types of non small cell lung cancers and with advanced fazes which can be stage III and stage IV . If for the first two stage I and II the survival rates are pretty good for squamous cell – epidermoid is 38% for first stage and 16% for the second stage , for adenocarcinoma 32% for first stage and for second stage 7% , undifferentiated large cell 30% for first stage and 6% for second stage, for stage III the survival rates are divided between the two types of stage III : stage III a and stage III b .

Although only 10% of the patients which are detected with advanced stages of lung cancer are included in stage 3a it is important to know what is the prognosis for stage 3a lung cancer because it is a little more better that stage 3 b . The prognosis for this 3a stage is 23%, meaning that only this percentage of patients manage to survive the five years period of survival that they are given when the lung cancer is it detected .

Stage 3a means that there has been discovered an advanced case of local cancer but which it has already spread to other parts and organs of the body and the major factor is that it reached the lymph nodes which are found on the same part as the lung tumors . If you have found out what is the prognosis for stage 3a lung cancer, you should consider the fact that stage 3b is defined more rougher than stage 3a because the tumor can be extremely large and they affected the nearby lymph nodes but there could also be different sized tumors but they reached lymph nodes from the same part of the body but which are localized at certain distance away from the tumors’ places .

The prognosis for this stage can be between also 23% as for stage 3a but it can also reach lower values such as only 10% because many of the patients have many internal complications and their main vital organs are already affected and they do not function normally and also the symptoms and effects on the patient’s body can become really hard to bear .
