As terrifying as it used to sound, Breast Cancer is no longer as dreadful as it was several years ago. It’s still a serious disease but thanks to improvements in cancer treatments, millions of women are surviving breast cancer today.
Early detection and treatment are keys to breast cancer survival
When breast cancer hasn’t strayed outside the breast, the five-year survival rate is close to 100%. So early detection through regular examinations is crucial. Women should begin doing monthly self-exams at age 20 and ask their doctors to do clinical exams at least every three years. By age 40, women should have annual mammograms and breast exams by a physician, in addition to monthly self-exams.
Some women may need to start mammograms and clinical exams earlier if they have a family history of the disease or carry one of the mutated genes – BRCA1 (breast cancer gene 1) and BRCA2 (breast cancer gene 2) – that predisposes them to breast cancer.
People who have Stage 0 (confined to the breast and not invading surrounding tissues) or Stage 1 (confined to the breast and invading surrounding breast tissue) have a five-year survival rate close to 100%. Higher stages (2, 3 and 4) mean that a more invasive tumor has spread to surrounding tissues, lymph nodes and/or to other organs. A woman with stage 4 cancer has a 20% chance of surviving for five years.
Mammography is the most reliable way to detect breast cancer.
The use of high-quality mammography is the most reliable way to detect breast cancer. In fact, because of its increased use, most women are diagnosed at early stages. Still, about 25% of breast cancers are first detected through a breast exam, about 35% by mammography and 40% through a combination of exam and mammography. Clearly, performing routine breast self-exams is still essential.
You can check for possible signs of breast cancer.
The three most common symptoms are:
1. Changes in the look or feel of the breast
2. Changes in the look or feel of the nipple
3. Nipple discharge
Sensitive or lumpy breasts (with or without fibrocystic disease) may make it harder for you to feel the lumps, hard knots of tissue or thickening in the breast that may be signs of breast cancer. Other signs include unusual swelling, warmth and pain that do not change with the menstrual cycle and/or do not go away. Lumps do not necessarily mean you have cancer; most are benign.
Possible changes to the skin include redness, darkening, puckering (a pulling that causes an indentation), or dimpling. The latter is often called peau d’orange, French for “the skin of an orange,” which resembles the slightly pebbled look the breast skin may have.
An inverted nipple – one that pulls inward – may be another sign. Nipples may also become itchy, scaly, sore, or have a rash or discharge. If you have any of these signs, see your doctor immediately.
Many factors are associated with an increased risk of breast cancer.
The presence of these risk factors does not mean you are likely to get the disease, and their absence does not offer absolute protection either. For example, a family history of breast cancer is considered a principal risk factor. Yet 80%-90% of women who get the disease have no known family history.
One of the most important factors is aging. The older you get, the greater the risk. At age 20 your risk is just 1 in 1,985. But at age 70, your risk skyrockets to 1 in 24. If you live to 85 years old, your odds increase to 1 in 8. The lifetime risk of breast cancer is 8%, or 1 in 12.
Approximately 5%-10% of breast cancers are due to inherited genetic mutations, like BRCA1 and BRCA2. People with these mutations have a 40%-80% risk of contracting breast cancer and a high risk of ovarian cancer. Other factors that increase risk are:
-First period before age 12; menopause after 55; excess weight after menopause
-First child after age 30; no children; taking birth control pills for five years or longer
-Drinking more than one alcoholic drink per day
-Current or recent use of combined estrogen and synthetic progestogen or progesterone hormone replacement therapy (HRT)
-High breast density; a previous biopsy showing hyperplasia (an excessive growth of tissue) or carcinoma in situ (a localized, microscopic form of cancer)
-Exposure to large amounts of radiation; treatment for Hodgkin’s disease at a young age
-History of breast or ovarian cancer.
Genetic mutations BRCA1 and BRCA2 raise your risk.
How do you estimate the likelihood of having a genetic mutation? Women with genetic mutations tend to get cancer before they are age 50. If you are older than 50 and do not have breast cancer, your odds of a genetic mutation are lower (but not zero).
