What is breast cancer? Breast cancer happens when cells in the breast begin to grow out of control and invade nearby tissue or spread throughout the body. Large collections of this out of control tissue are called tumors. Some tumors are not really cancer because they cannot spread or threaten someone?s life. These are called benign tumors. The tumors that spread throughout the body or invade nearby tissue are considered cancer and are called malignant tumors. Theoretically, any of the types of tissue in the breast can form a cancer, but usually it comes from either the ducts or the glands. Because it may take months to years for a tumor to get large enough to feel in the breast, we screen for tumors with mammograms, which can sometimes see disease before we can feel it.

Am I at risk for breast cancer? Breast cancer is the most common malignancy affecting women in North America and Europe. Every woman is at risk for breast cancer. The lifetime risk of any particular woman getting breast cancer is about 1 in 8 although the lifetime risk of dying from breast cancer is much lower at 1 in 28. Risk factors for breast cancer can be divided into those that you cannot change and those that you can change. Some factors that increase your risk of breast cancer that you cannot alter include being a woman, getting older, having a family history (having a mother, sister, or daughter with breast cancer doubles your risk), having a previous history of breast cancer, having had radiation therapy to the chest region, being Caucasian, getting your periods young (before 12 years old), having your menopause late (after 50 years old), never having children or having them when you are older than 30, and having a genetic mutation that increases your risk. Genetic mutations for breast cancer have become a hot topic of research lately. Between 3% to 10% of breast cancers may be related to changes in either the gene BRCA1 or the gene BRCA2. Women can inherit these mutations from their parents and it may be worth testing for either mutation if a woman has a particularly strong family history of breast cancer (meaning multiple relatives affected, especially if they are under 50 years old when they get the disease). If a woman is found to carry either mutation, she has a 50% chance of getting breast cancer before she is 70. Family members may elect to get tested to see if they carry the mutation as well. If a woman does have the mutation, she can get more rigorous screening or even undergo preventive (prophylactic) mastectomies to decrease her chances of contracting cancer. The decision to get tested is a highly personal one that should be discussed with a doctor who is trained in counseling patients about genetic testing. Certain factors which increase a woman?s risk of breast cancer can be altered including taking hormone replacement therapy (long term use of estrogens with progesterone for menopause symptoms slightly increases your risk), taking birth control pills (a very slight increased risk that disappears in women who have stopped them for over 10 years), not breastfeeding, drinking 2 to 5 alcoholic drinks a day, being overweight (especially after menopause), and not exercising. All of these modifiable risk factors are not nearly as important as gender, age, and family history, but they are things that a woman can control that may reduce her chances of developing a breast malignancy. Remember that all risk factors are based on probabilities, and even someone without any risk factors can still get breast cancer. Proper screening and early detection are our best weapons in reducing the mortality associated with this disease. How can I prevent breast cancer? The most important risk factors for the development of breast cancer cannot be controlled by the individual. There are some risk factors that are associated with an increased risk, but there is not a clear cause and effect relationship. In no way can strong recommendations be made like the cause and effect relationship seen with tobacco and lung cancer. There are a few risk factors that may be modified by a woman that potentially could influence the development of breast cancer. If possible, a woman should avoid long-term hormone replacement therapy, have children before age 30, breastfeed, avoid weight gain through exercise and proper diet, and limit alcohol consumption to 1 drink a day or less. What screening tests are available? The earlier breast cancer is found, the more likely it can be treated and cured. For this reason, we use mammograms, clinical breast exams, and breast self-exams. Screening mammograms are simply x-rays of each breast. The breast is placed between two plates for a few seconds while the x-rays are taken. If something appears abnormal, or better views are needed, magnified views or specially angled films are taken during the mammogram. Mammograms often detect tumors before they can be felt and they can also identify tiny specks of calcium that could be an early sign of cancer. Regular screening mammograms can decrease the mortality of breast cancer by 30%. The majority of breast cancer cases are associated with abnormal mammographic findings. Woman should get a yearly mammogram starting at age 40 (although some groups recommend starting at 50), and women with a genetic mutation that increases their risk or a strong family history may want to begin even earlier. Between the ages of 20 and 39, every woman should have a clinical breast exam every 3 years; and after age 40 every woman should have a clinical breast exam done each year. A clinical breast exam is an exam done by a health professional to feel for lumps and look for changes in the size or shape of your breasts. During the clinical breast exam, you can learn how to do a breast self-exam. Every woman should do a self breast exam once a month, about a week after her period ends. If you find any changes in your breasts, you need to contact your doctor. What are the signs of breast cancer? Unfortunately, the early stages of breast cancer may not have any symptoms. This is why it is important to follow screening recommendations. As a tumor grows in size, it can produce a variety of symptoms including: ? lump or thickening in the breast or underarm ? change in size or shape of the breast ? nipple discharge or nipple turning inward ? redness or scaling of the skin or nipple ? ridges or pitting of the breast skin If you experience these symptoms, it doesn?t necessarily mean you have breast cancer, but you need to be examined by a doctor. www.your-breast-cancer.com
