Cancer is a very broad term used to describe any abnormal cell growth found in the body. It sometimes shows up as a tumor, but in the the case of Leukemia, the diseased cells show up in the blood and the body's tissues. Cancer can afflict just about any organ or part of the body.

In some cases, cancer is caused by a person's lifestyle. For example, smokers are more prone to lung, throat and mouth. People who tan or work outdoors without proper sun protection are more prone to skin cancer. However, cancer is not always attributed to an individuals' lifestyle. Genetics are also a factor. Oftentimes, doctors are unsure of cancer's causes. It is something that just happens.  

Cancer treatments vary. The type of treatment a doctor chooses depends on a number of things. How aggressive a patients particular type of cancer is. Is there a chance that it can be cured? Is it operable? Some cancer treatments include chemotherapy , radiation therapy, and bone marrow transplants.

Cancers of the breast, cervix, lung and prostate can be prevented. Women age 40 and over should get annual mammograms and perform self-breast exams after each menstrual cycle. Doctors also urge women to get pap smears to check for abnormal cells. By checking for these cells regularly, doctors will be able to find and treat cervical cancer while it is still in its early stages. Men who are age 50 and older should get their prostates checked annually. Both, men and women can prevent colon cancer by getting a smear test.
