Your Basic Knowledge on Cancer

What is Cancer

Cancer is any malignant growth caused by abnormal and uncontrolled cell division.It is a class of diseases characterized by out-of-control cell growth. There are many different types of cancer; each is classified by the type of cell that is initially affected. Cancer is harmful to the body when damaged cells divide uncontrollably to form lumps of tissue called tumors, which can grow and with the digestive, nervous, and circulatory systems, and they can release hormones alter body function. When a tumor spreads to other parts of the body and grows and destroying other healthy tissues, it is said to have metastasized, which results a serious condition

Classification of Cancer

Absolute way to diagnose cancer is extracting cancer cells and looking at them under a microscope is the only, which is called a biopsy.
