== Types of Cancer ==
Cancer can be classified into several types based on the tissue of origin:
* '''Carcinomas''': Cancers that originate in the skin or tissues that line internal organs.
* '''Sarcomas''': Cancers that arise from connective tissues such as bone, cartilage, fat, and blood vessels.
* '''Leukemias''': Cancers that begin in the blood-forming tissue, such as the bone marrow, and result in high numbers of abnormal blood cells.
* '''Lymphomas''': Cancers that begin in the immune system.
* '''Central Nervous System Cancers''': Cancers that begin in the tissues of the brain and spinal cord.
