Breast cancer begins in the cells of the breast. The exact type of breast cancer depends upon where the cancer started. Some types of breast cancer are more common than others. Each of the various types has its own characteristics and opportunities for cure.

Estimates from the American Cancer Society say that one out of every eight women will battle breast cancer. Although it is not as prevalent as other diseases, including cardiovascular disease, breast cancer is particularly scary because of the risks of illness, disfigurement, and death it brings with it. We don't yet understand all of the complicated factors required to determine a particular woman's breast cancer risk.

There are many breast cancer risk factors. Some of these are your age, past incidences of breast lesions, your family's medical history, and genetics. If you've had abnormal biopsies in the past or been exposed to some chemicals or radiation, those can present a risk as well, although a lesser one. The age a woman first gave birth, the age of her first period, the age she went through menopause, and whether or not she is overweight may also influence the chances of getting breast cancer to a lesser degree. However, 70 percent of women who get breast cancer do not fall into these risk groups.

The precise causes of breast cancer, and its risks, remain elusive and a subject of intense study. However, physicians and scientists have developed tools to help a woman better understand her unique risk profile, estimate her unique risks, and take any actions towards reducing those risks which can be reduced, such as obesity. Some of these tools are available online through the websites of major universities and other institutions dedicated to the study and treatment of breast cancer.

Merely the word tumors is often enough to strike fear. However, this simply means an abnormal growth; there is no definitive link with cancer. Although it is natural that women are nervous about any lumps, it is always best to discuss such findings promptly with your doctor before worrying too much as the majority turn out to be non-cancerous and benign.

A doctor must be consulted if you find anything abnormal about your breasts. The doctor will perform tests to learn more about the abnormality. The mammogram is one type of screening test that you should get regularly from your doctor. Online you can find a lot of information about breast cancer risk. You can also talk to your doctor for more information.
