We've often heard of cancer, but do we really know what it is? For sure, we know it's a disease, and can be very deadly and fatal, but how does it happen? Is it caused by bacteria, virus or some other foreign body?
Cancer is, in its simplest form, the result of cells being mass produced in overdrive mode. This result in a mass of extra tissue or cells called a tumor. Tumors can be benign or malignant. Benign tumors do not spread and can be removed successfully. Malignant tumors contain cells that can spread and infect other body organs and tissues. So when we say that cancer eats away at a person, it actually means that the cancer is slowly taking over by mass-producing itself, taking away much needed nutrients away from the body's other processes.
