Lung cancer is one of the most common cancers in the world. It is the leading cause of cancer death among men and women in the United States. Cigarette smoking causes most lung cancers. A greater number of cigarettes they smoke daily newspapers and the younger you start smoking, the greater the risk of developing lung cancer. Exposure to high levels of pollution, radiation and asbestos can also increase the risk.

Common symptoms of lung cancer include:

1. A cough that does not go away and worsens over time
2. Constant chest pain
3. Cough with bloody sputum
4. Shortness of breath, wheezing or hoarseness
5. Repeated problems with pneumonia or bronchitis
6. Loss of appetite or weight loss
7. Fatigue

There are many types of lung cancer. Each grows and spreads differently and treated differently. Treatment also depends on the stage or how far along you are. Treatment can include chemotherapy, radiation and surgery.

These symptoms may be caused by cancer or other conditions. It is important to consult a doctor.

Non-small cell lung Cancer Treatment
Patients with metastatic non-small cell lung cancer can be treated in several ways. The choice of treatment depends mainly on the size, location and grade of tumor. Surgery is the most common way to treat this type of lung cancer. Cryosurgery, a treatment that freezes and destroys cancer tissue, can be used to control symptoms in stages (stages) of lung cancer last non-small cell. Radiation and chemotherapy can also be used to slow the progression of the disease and to control symptoms.

Small Cell Lung Cancer Treatment
Lung cancer small cell spreads quickly. In many cases, cancer cells have already spread to other parts of the body when diagnosed. To reach cancer cells throughout the body, doctors almost always use chemotherapy. Treatment may also include radiation therapy to the tumor in the lung or tumors in other parts of the body (as in the brain). Some patients receive radiation therapy to the brain even when cancer is not there. This treatment, called prophylactic cranial irradiation was given to prevent tumors from forming in the brain. Surgery is part of the treatment plan for a small number of patients with lung cancer small cell.

The symptoms of lung cancer does not usually appear in the early stages of lung cancer but arise when it has already spread too much to increase the chance of cure. In fact, since that occurs the first malignant cell until a person consult a doctor first before symptoms of the disease can take many years.

Among the most common symptoms are:

- Persistent cough.
- Chest pain that increases with breathing.
