Understanding Lung Cancer: Types, Causes & Adenocarcinoma

Lung cancer causes more cancer deaths in both men and women than any other type of cancer, according to the American Cancer Society. Of the several types of lung cancer, the most common type is usually caused by tobacco smoking. Exposure to pollutants such as radon and asbestos are other potential causes of this cancer.

Types

• Currently, the most common type of lung cancer is adenocarcinoma. According to the American Cancer Society, this form became the most common in the 1980s--decades earlier, squamous cell carcinoma of the lung was most common.

Features

• Adenocarcinomas are malignant tumors that arise in glandular tissues.

Symptoms

• Symptoms of adenocarcinoma of the lung include chronic cough, fatigue and shortness of breath.

Treatment

• When possible, surgical removal of cancerous areas is one main form of treatment, followed by chemotherapy or radiation.

Prevention/Solution

• As cigarette smoking is the primary cause of this type of lung cancer, not smoking may reduce your risk.
