New Type of Treatment Some human diseases involve the unregulated growth of cells. Although some patients are not
affected by these growths, many are harmed. Cells in harmful growths divide uncontrollably and
can eventually Invade other cells, tissues, and organs of the body.
Some patients carry a mutation on one or more growth-suppressor genes (GSGS). GSGS help to
repair damage to DNA. This mutation decreases the Individual's ability to fight these harmful
growths. Recently, researchers reported on the results of using a combination of two types of
medicine to treat patients with unregulated growths caused by a lack of functioning GSGS.
