Cancer is not just one disease, but a group of almost one hundred diseases. These diseases have two common characteristics. First, cells begin to grow out of control in the body. Second, those cells have the ability to travel from their original site to other locations in the body. If the spread is not controlled, cancer can result in death.
The major risk factors for cancer are tobacco and alcohol use, diet, sexual and reproductive behavior, infectious agents, family history, occupation, radiation, and pollution.
The American Cancer Society estimates that about 40 percent of all cancer deaths in the United States are caused by tobacco and excessive alcohol use. An additional one-third of the deaths are caused by poor diet and nutrition. The vast majority of deaths from skin cancer are due to overexposure to ultraviolet light in the sun's rays.
Cancer is a progressive disease. That is, it goes through a series of stages that are progressively worse. The symptoms are different at each stage. One of the earliest symptoms of cancer is pain. As tumors grow, they push on organs, nerves, blood vessels, and other tissues around them, causing pain.
The earlier cancer is detected, the more effectively it can be treated. For this reason, the American Cancer Society has prepared a list of seven warning signs of cancer. They are:
? Change in the size, color, or shape of a wart or mole
? A sore that does not heal
? Persistent cough, hoarseness, or sore throat
? lump or thickening in the breast or elsewhere
? Unusual bleeding or discharge (release of fluids)
? Chronic indigestion or difficulty in swallowing
? Any change in bowel or bladder habits
