Cancer (Malignancy)

Cancer, also known as malignancy, is a group of diseases characterized by the uncontrolled growth and spread of abnormal cells. Normally, our body's cells grow, divide, and die in an orderly way. Cancer occurs when cells mutate and start to grow out of control, forming a mass called a tumor. These cancerous cells can invade nearby tissues and, in some cases, spread to distant parts of the body through the bloodstream or lymphatic system, a process called metastasis.
