Leukemia

According to the Mayo Clinic, doctors classify leukemia in two ways.

• Speed of progression
• Types of cells affected

The major types of leukemia are:

• Acute myelogenous leukemia (AML)

Leukemia is cancer of your body's blood-forming tissues, including the bone marrow and lymphatic system. The word "leukemia" means "white blood" in Greek. The disease usually starts in the white blood cells.

Mary Shoman, in the Thyroid Disease Guide, reports that "... thyroid cancer patients face a 30% increased risk of second primary cancer, when compared to the general population. It is important to note that these are not metastases -- a spread -- of the initial thyroid cancer -- but instead, appearance of an entirely new cancer."
