What are the different types of cancers?
Cancers are classified in two ways: Histological type, or the type of tissue in which the cancer originated, and by primary site, or the location in the body where the cancer first developed.
 
 From a histological standpoint, there are hundreds of different cancers, which are grouped into six major categories: 
 1. Carcinoma
 2. Sarcoma
 3. Myeloma
 4. Leukemia
 5. Lymphoma
 6. Mixed Types
