Lung cancer is a disease of uncontrolled cell growth in lung tissue. This growth can lead to metastasis, the spread to adjacent tissue and prematurely enter the lungs. It 's the most important cause of cancer death in men and the second most common in women.

The most common symptoms of lung cancer:
1st continuous chest pulse
2nd persistent cough that has become seriously
3rd Shortness of breath, wheezing, orHoarseness
4th constant problems with pneumonia or bronchitis
5th Hemoptysis
6 Inflammation of the throat and face
7th Loss of appetite or significant weight loss
8th Exhaustion

Types of lung cancer:

A.-small cell lung cancer occurs when malignant cells form in the lung tissue.
small lung has three different types, classified according to the type of cells develop, such as cancer. Thisare:

1st small cell carcinoma
2nd group of small and large cell carcinoma cells.
3rd City of small cell carcinoma.

These three types may contain many different types of cells. The type of tumor cells can grow and multiply all in different ways.

Stage cancer cell lung small

Limited stage – the cancer begins in the lung tissue and adjacent lymph nodes. Lymph nodes are small bean-shaped structures near theLungs.

Large Stage – cancer increased body through the lungs to other parts des
B. large cell lung cancer is a disease in which malignant cells form in the tissues of the lungs.

Five major types of lung cancer

The five main types of cancer have different types of tumor cells. Cancerous cells for each category and multiply by producing unusual effects:

1st squamousCarcinoma – cancer begins in squamous cells, thin, flat cells that look like fish scales. It is called squamous cell carcinoma.
2nd large cell carcinoma – cancer, in which cells are large and irregular, seem to be, when examined microscopically.
3rd adenosquamous carcinoma – cancer that begins cells. Microscopic cancer cells seem to be a company at the time under control.
4th Adenocarcinoma – cancer that begins in active groups of glands.
5th undifferentiated carcinoma – cancer cells, which appear to be abnormal. They spread rapidly.

Treatment:

1st – Surgery is the ideal drug for lung cancer. The body is usually up to the opening of the lungs directly handled surgery.
2nd Radiation is a common treatment of lung cancer. Radiotherapy uses high energy radiation to destroy cancer cells. He lost only cells in the treated area.

Others External radiationLung cancer is the most common radiation treatment for people. Radiation comes from a large machine outside the body. Mostly people in hospital or clinic for treatment. Treatments are usually 5 days a week for more than a few weeks.

b. internal radiation is rare. The radiation is released from a seed, wires or other devices for the body.

Treatment of Large Cell Lung Cancer:

cancer – chemotherapy treatment or to do thisavoid the use of drugs on cells, the growth of cancer. drugs are taken either orally or injected into the veins and muscles to destroy cancer cells. These drugs are in the bloodstream of the body to treat cancer cells. When chemotherapy is placed prone, especially in the spinal column, an organ or a body cavity such as that of these drugs usually need the cancer cells there.
or laser therapy – laser is used to destroy cancer cells.

WEDNESDAY, March 24 (HealthDay News) -- Chemotherapy improves survival for patients with operable non-small cell lung cancer, say researchers who reviewed nearly 50 studies.

The first meta-analysis of 34 studies involving almost 8,500 patients (and more than 3,300 deaths) showed that survival at five years was 64 percent for patients who had chemotherapy and surgery, and 60 percent for patients who had surgery alone.

The second meta-analysis of 13 studies with 2,660 patients (1,909 deaths) showed that survival at five years was 33 percent for patients who had surgery plus radiotherapy and chemotherapy, and 29 percent for patients who had surgery plus radiotherapy alone.

The report was released online March 23 in advance of publication in an upcoming print issue of The Lancet.

"In both meta-analyses we noted little variation in effect according to the type of chemotherapy, other trial characteristics, or patient subgroup," wrote the British and French researchers.

According to a team led by Sarah Burdett of the Medical Research Council Clinical Trials Unit, London, adding in chemotherapy boosted outcomes whether or not patients got the treatment alongside surgery alone, or surgery plus radiotherapy. They contend that, in patients deemed suitable, "platinum-based chemotherapy should be considered for patients at high risk of recurrence -- i.e., those with stage 1B, 2 or 3 disease."

The finding supports the use of chemotherapy in patients with non-small cell lung cancer who have also undergone tumor-removing surgery, Dr. Gregory P. Kalemkerian, of the University of Michigan, wrote in an accompanying commentary.

"Although the survival benefit seems small, worldwide adoption of adjuvant chemotherapy could save up to 10,000 lives every year," he said.
