Lung Cancer Stages 1-4
Lung Cancer Stages 1-4 She smokes lung cancer and often smokes, but she doesn’t always go hand in hand. During the course of lung cancer, symptoms of lung cancer include cough, wheezing, shortness of breath and bloody mucus. Treatment includes surgery, chemotherapy and/or radiation. Lung cancer is cancer that starts in the lungs.
The most common type is non-small cell lung cancer (NSCLC). NSCLC accounts for about 80 to 85 percent of all cases. Thirty percent of them begin in the cells that form the lining of the body cavities and surfaces. This type usually occurs in the outer part of the lungs (adenocarcinomas). Thirty percent of the airway (squamous cell carcinoma) begins in the cells surrounding the passages.
A rare subset of adenocarcinoma begins in small air sacs (alveoli) in the lungs. In situ is called adenocarcinoma (AIS). This is not aggressive and may not penetrate the surrounding tissues or may require immediate treatment. The fastest growing types of NSCLC include large-scale carcinoma and neuroendocrine tumors.

Small cell lung cancer (SCLC) represents approximately 15 to 20 percent of lung cancers. SCLC is growing and spreading faster than NSCLC. This also increases the likelihood of response to chemotherapy but is also less likely to be treated with treatment.
Lung Cancer Stages 1-4: In some cases, lung cancer tumors include both NSCLC and SCLC cells.
Mesothelioma is a different type of lung cancer. It is usually associated with asbestos exposure. Carcinoid tumors begin in hormone cells that produce (neuroendocrine) cells.
Tumors in the lungs can become quite large before you notice symptoms. Early symptoms mimic a cold or other common conditions, so most people don’t seek immediate medical attention. That’s one of the reasons lung cancer is not usually diagnosed at an early stage.

Lung Cancer Stages 1-4
Cancer stages show how far cancer has spread and helped with treatment. The chance of successful or curative treatment is much higher if early stage lung cancer is diagnosed and treated before it spreads. Because lung cancer does not cause obvious symptoms in the earlier stages, the diagnosis often doesn’t come until after it spread.
Lung cancer, which is not small, has four main stages:
- Stage 1: Cancer is found in the lungs but has not spread outside the lungs.
- Stage 2: Cancer is found in the lungs and nearby lymph nodes.
- Stage 3: Cancer lies in the lung and lymph nodes in the middle of the breast.
- Stage 3A: Cancer is found in lymph nodes, but only on the same side of the breast where cancer began to grow.
- Stage 3B: Cancer has spread to the opposite side of the chest or to lymph nodes above the collar.
- Stage 4: Cancer has spread to both lungs, to the area around the lungs or to distant organs.
Small cell lung cancer (SCLC) has two main levels. At the limited stage, cancer is only found in a lung or near lymph nodes on the same side of the breast.
