Cancer is a term for diseases in which abnormal cells divide without control and can invade nearby tissues. Cancer cells can also spread to other parts of the body through the blood and lymph systems. There are several main types of cancer such as:
- Carcinoma – is a cancer that begins in the skin or in tissues that line or cover internal organs.
- Sarcoma – is a cancer that begins in bone, cartilage, fat, muscle, blood vessels, or other connective or supportive tissue.
- Leukemia – starts in blood-forming tissue, such as bone marrow, and causes large numbers of abnormal blood cells to be produced and enter the blood.
- Lymphoma and multiple myeloma – begin in the cells of the immune system.
- Central nervous system cancers – begin in the tissues of the brain and spinal cord.
