Cancer
From Wikipedia, a free encyclopedia written in simple English for easy reading.
Cancer can mean a number of different illnesses. Cancer generally means "uncontrolled growth". Cancer cells go around the body's normal signals that limit the life and growth of cells. Cancer cells are often fatal, because they can move throughout the body. When they move and then continue to grow, it is called "metastasis".
Cancer is a leading cause of death -- according to the World Health Organization, 12.5% of all deaths worldwide. Some things (whether controllable or uncontrollable) that can be causes or triggers of various types of cancer, include tobacco (smoked or smokeless), sunlight, radiation, including X-rays in large doses, chemicals used in construction and manufacturing (for example, asbestos and benzene), high-fat or low-fiber diets, air and water pollution, low fruit and vegetable intakes, overweight and obesity, not enough physical activity, drinking too much alcohol, and household use of some chemicals.
Although a cure has not been found yet, cancer can be partly treated using radiotherapy (also called radiation therapy), chemotherapy, or immunotherapy (also called biological therapy).
There are many different types of cancer - each have there own symptoms and causes. Some people can handle cancer better than others but to everyone it is harmful and can be fatal.
