Read the passage below and decide whether the statements are TRUE or FALSE?

The overgrowth of cells leads to the development of tumors and the harmful effects of cancer. In lung cancer, this pattern of cell overgrowth occurs in the lungs, which are vital organs for breathing and gas exchange. Doctors typically diagnose two lung cancer types, small cell and non-small cell, depending on how they appear under a microscope. A person is more likely to have non-small cell lung cancer than small cell.

While anyone can develop lung cancer, cigarette smoking and exposure to smoke can increase the likelihood that a person will experience the condition. Lung cancer can develop if a person has a history of exposure to inhaled chemicals or other toxins. Even if this exposure to chemicals and other toxins was a long time ago, it could cause changes in lung cells that lead to cancer.

If a doctor identifies a suspicious lesion on an imaging study, they may recommend taking a sample of lung tissue to test for potentially cancerous cells. There are different ways to take a tissue sample, and the method often depends on the location of the lesion. One example is when a doctor performs a bronchoscopy, which involves inserting a special thin, lighted scope with a camera on the end. This helps the doctor to see the lesion and then to obtain samples. Less accessible lesions in the lungs may require a more invasive surgical procedure to remove lung tissue, such as thoracoscopy or video-assisted thoracic surgery.

Question: The effect of cancer is the result of the overgrowth of cells.

A. True

B. False
