What is Cancer?

In short cancer is a multifactorial and autoimmune disease. When a lot of cell club together and they create a tumor, it is called a cancers tumor. Cancer is the uncontrolled growth of abnormal cells in the body. Cancer develops when the body’s normal control mechanism stops working. Old cells do not die and instead grow out of control, forming new, abnormal cells. These extra cells may form a mass of tissue, called a tumor. This abnormal cell growth may occur in blood, tissue or bones.
What are the most common forms of cancer?
There are five main categories of cancer:
• Leukemia begins in the blood and bone marrow.
• Lymphomas start in the immune system.
• Central nervous system cancers develop in the brain and spinal cord.
• Carcinomas begin in the skin or tissues that line the internal organs.
• Sarcomas develop in the bone, cartilage, fat, muscle or other connective tissues.
