Lung Cancer Prognosis |
Lung cancer, like all the cancers, comes from an abnormality of basic units of life in human body. Normal body can support certain systems of checks and balances of cell development, so that cells will divide only when that is necessary. Disruption of this system on cell growth results can results in an uncontrolled division and proliferation of cells which eventually create a mass that is called a tumor.
Tumors can be malignant and benign. When there is word about cancer, then that is only referring to those tumors which are malignant, that is because benign tumors can, in most of the cases, be simply removed so they don't spread on other parts of body.
On the other hand, malignant tumors are continuously growing aggressively and attack other body tissues. They enter the bloodstream or lymphatic system, and then they create new tumors on other body parts. This process is called tumor transplantation or metastasis.
Lung cancer has tendency of spreading after short amount of time after the formation, which makes him very dangerous to life and it is one of the forms of cancer which are hardest to cure. Places where metastases are mostly find are liver, brain and bones, but it can be almost any other part of body.
It can occur pretty much in any parts of the lung, but more than 90 percent of lung cancers arise from their epithelial cells and smaller airways so this is the reason why it is being called lung cancer.
The main function of the lungs it to exchange certain gases that are between air we breathe and the blood. Through lungs, carbon dioxide is being removed from blood, and oxygen from the air enters in our bloodstream. Right lung has three lobes, while the left lung is primarily composed of two lobes called Lingula, which is kind of an equivalent of middle lobe that is placed on the right side. The lungs and the inner side of the chests are covered with thin layer of tissue which is called pleura.
Cancer can arise simply from the pleura. That type of cancer is also called mesothelioma and it also belongs to a very aggressive and dominant type of tumor that is highly unlikely to cure. Very rarely malignant tumors in the chance can arise from supporting tissue or blood vessels.
Lung cancer prognosis may indicate on a chance to cure the lung cancer and it primarily depends on the localization of that cancer, size, symptoms presence, type of lung cancer and most importantly is to discover your lung cancer before it is too late.
SCLC is the most aggressive type of lung cancer with low survival rate, and with a median survival of only two to five months after diagnosis, if the cancer is not cured. However, this type of lung cancer is at the same time the type of lung cancer which is very sensitive to chemotherapy or radiation. SCLS is commonly spreading very quickly and it usually metastasizes at the time of diagnosis, methods like surgical removal or even localized radiation therapy can be far more useful and effective in treating of SCLC.
Survival rate for patients with this kind is not very encouragable, mainly because of the fact that only around 5-10 percent of patients with this type of cancer can survive over five years after the time of diagnosis. Most of the survivors have had localized SCLS disease.
At lung cancer of bigger cells, the very most important prognostic factor can be stage of the disease when it has been diagnosed. Results of standard procedure of medication can be generally poor at all of the stages of lung cancer, as well as those with tumors who can be fully removed. In the initial stage of cancer when tumor can be surgically fully removed, five year survival rate is around 80 percent.
Radiotherapy can also be very effective for smaller number of patients with this type of cancer, and most of them can experience relieved symptoms. In more advanced stages of the lung cancer, chemotherapy can give very modest results and full survival rate can be very small.
Lung cancer prognosis can be very effective if you check it at an early stage of lung cancer, if lung cancer has been discovered at more advanced stages than chances of survival are very small.
