Theyre created by averaging the results of large numbers of healthy individuals. Blood cells make up the other 45%. This is because chemotherapy agents and radiation is often cytotoxic. That said, when used appropriately, screening can reduce lung cancer deaths. A CBC does many tests to measure and study red blood cells, white blood cells and platelets. In the U.S., about 30% of cancer deaths are due to screenable cancers like breast, prostate, cervical, lung, and colorectal. Says Hawk: They identify things that we dont have solutions for..

When it comes to your red blood cells, size matters. These cells or portions of DNA can be distinguished from normal cells by the presence of the mutations that are characteristic of cancer. These cells are called agranulocytes because they lack the granules of granulocytes. Unless you work in the medical field, figuring out what all of those values mean and how to interpret them can sometimes be a challenge.
