10 Reasons Why Your Urine Is Bloody

6. Cancer

Cancer is a broad term that describes a variety of disorders characterized by the uncontrollable division of aberrant cells that can invade and destroy normal human tissue. Cancer has the potential to spread throughout your entire body. Cancer is the world’s second largest cause of death. However, because of advancements in cancer detection, therapy, and prevention, survival rates for many types of cancer are improving. Changes (mutations) in the DNA within cells cause cancer. Each gene in a cell has a collection of instructions that inform the cell what functions to execute as well as how to grow and divide. Errors in the instructions can cause a cell to stop functioning normally and even cause it to become malignant.
