Cancer
Cancer is a collection of various diseases characterized by abnormal cell growth. Cancerous cells divide and replicate without stopping, spread to surrounding areas and can form malignant tumors. Benign tumors are not cancerous. Unlike malignant tumors, once removed, they don't usually grow back. Cancer can begin almost anywhere in the body and can have varying levels of severity.
