What is cancer? Cancer is the uncontrolled growth of abnormal cells in the body. Cancer develops when the bodyâs normal control mechanism stops working. Old cells do not die and instead grow out of control, forming new, abnormal cells. These extra cells may form a mass of tissue, called a tumor.
A tumor is any abnormal mass of tissue or swelling. Like a cyst, a tumor can form in any part of the body. A tumor can be benign or cancerous (malignant). Cysts that appear uniform after examination by ultrasound or a computerized tomography (CT) scan are almost always benign and should simply be observed.
