2. Leukemia.
A form of cancer that affects the bone marrow and blood, people who are afflicted with leukemia suffer from low platelet counts. This type of cancer occurs when the body produces an abnormally high amount of white blood cells at a very fast rate. There are several types of white blood cells; lymphocytes, neutrophils, monocytes, basophils, and eosinophils are the most common and most important.
The white blood cells (leukocytes), along with red blood cells and platelets, are produced in the bone marrow and play a vital role in the function of the immune system. They attack viruses, bacteria, and all types of germs that enter the body and fight off infections.
When the bone marrow produces too many blood cells at a fast pace, it is unable to generate red blood cells and platelets. Those who have leukemia have high white blood cell counts and low platelet counts.
