In terms of deaths caused by various forms of cancer, lung cancer is one of the second only to breast cancer. The National Cancer Institute recently reported that an estimated 172,570 new cases of lung cancer reported in the companies this year and that 163,510 Americans die from this disease.

Lung cancer is caused primarily by smoking. One expert said that) (in the case of lung cancer small cell carcinoma, it is almost always caused by smoking.

The lung cancer than lung cancer, because it begins in the lungs. The right lung has three sections, the left lung has two. Each section is called lobes. Sometimes the term “lung cancer” is used to develop lung cancer as most lung cancer develops in one of two related breathing tubes, the bronchi of the lungs.

There are essentially two types of lung cancer. One is the cancer of small cell lung (SCLC) is already in the preceding paragraph. The other is the non-small-cell lung cancer (NSCLC).

Cancer non-small cell lung has three subtypes: adenocarcinoma, squamous cell carcinoma, large cell undifferentiated. NSCLC is the least “serious” between the two types. Indeed, if detected early, it is possible that it can not be cured by surgery.

Accounts Andenocarcinoma about 40 percent of cancer cases in the United States is the most common cancer among women and can be seen in non-smokers. Carcinoma represents approximately 30 to 35 percent of lung cancers and tends to remain localized to the breast than other types of lung cancer. Large Cell Undifferentiated Carcinoma of only about five to 15 per cent of cases of lung cancer is in S. U. The incidence of this cancer seems to be declining.

The form of the worst and most aggressive of lung cancer is small cell lung cancer. It is only 15 to 20 per cent of all cases of lung cancer. It spreads to lymph nodes and other organs more quickly than NSCLC, but appears more sensitive to chemotherapy.

Non-small-cell lung cancer is described in stages? Stage I to IV WebMD reports recently, survival rates of NSCLC as:

Level 1A or 1B, without lymph node involvement has a rate of five-year survival from 43 to 64 percent when treated surgically.
Stage II or IIB with a single lymph node, if it is treated by surgery, has a survival rate at five years 20 to 40 per cent.
Stage IIIA with a single lymph nodes in the middle of the chest when she was treated surgically with a five-year survival is 15 to 25 per cent.
Stage IIIB with lymph nodes in the chest and neck when they are treated by radiotherapy without further treatment, he signed a survival rate of five to seven per cent. Stage IIIB with lymph nodes in the chest and neck when she should be treated by radiotherapy and chemotherapy, survival rates five years between Sieben and 17 per cent. Stage IV with extensive involvement of lymph nodes or the cancer has spread to other organs, hen treated with chemotherapy and palliative care to reduce symptoms and increase the comfort level is a survival rate at one year .

The prognosis is much worse for patients with small cell carcinoma of the lung. This form of cancer is detected in two stages: limited or full. The limited version is there in one lung and lymph nodes were found in the vicinity. The global nature outside the lungs to other parts of the breast or spread throughout the body (metastasis). Limited SCLC when treated with chemotherapy and radiotherapy have been, had a mean survival time of 18 to 20 months. The extensive form of SCLC when treated with chemotherapy had a survival period of 10 to 12 months. TTWO survival rate at one year is one to three per cent and the survival rate at five years less than two percent.

Most people diagnosed with SCLC will die despite the best treatments available.

During surgery, plays the main role in the treatment of non-small-cell lung cancer, chemotherapy is always the choice of treatment of lung cancer small cell. In the case of limited stage SCLC, radiation therapy can be used as a cancer is still localized in the chest area, where the radiation can be targeted.

Small Cell Cancer cells are so small, not that they see on the scans. Even in the case of limited stage SCLC, it is possible for individual cells to break with the primary cancer and migrate throughout the body. For this reason, chemotherapy is the treatment of choice as it treats the whole body, unlike radiation, which should focus on a selected area. In the first act, chemotherapy is the preferred treatment for limited stage and extensive cancers small cell lung cancer.
