Call it a boob fetish, but we're always thinking about our breasts - squeezing them into push-up bras against their will, agonizing over cup size in bathroom mirrors, keeping them from bouncing when we're on the treadmill. We also worry about them. But the fact is, our breasts are constantly in flux, a function of fertility, hormones and other factors such as diet. And though breast cancer concerns are always at the back of our minds, there's no need to stress. Prepare to expect anything from those unpredictable orbs.
1. Your breasts are never static. Breasts fluctuate in size, shape and feel from month to month - the result of natural hormonal changes that occur as a woman's body prepares for a possible pregnancy.
2. Breasts keep on growing. Though they technically stop growing when a woman is in her early 20s, weight gain, pregnancy and hormonal drugs - such as the pill - can enlarge breast size.
3. It can be normal to have lumpy boobs. Many women have breast tissue that feels like small ridges or marbles beneath the skin. It simply means the breast's many glands are being overstimulated by the increase in estrogen during the menstrual cycle: a benign condition referred to as fibrocystic change.
4. Breasts can swell. Although sudden swelling of a breast accompanied by heat, tenderness or itching could be a sign of mastitis (an inflammation of the breast common when breastfeeding) or very rarely inflammatory breast cancer, if the swelling occurs every month and occurs in both breasts, it is likely related to the hormonal ups and downs brought on by the menstrual cycle. In fact, breasts can go up a whole cup size. Check out any irregular swelling with your doctor.
5. Keep an eye on dense breasts. Women with breasts that have more fibrous and connecting tissue and less fatty tissue have higher breast cancer rates. Dense tissue makes mammograms harder to read, making abnormalities easier to miss.
6. Tenderness is common. If your breasts feel sore - especially in the outer quadrants close to the underarm area - it's likely a reflection of your menstrual cycle in which breast lobules enlarge and become painful. Fibrocystic breasts can become tender in any part of the breast.
7. Going braless won't make your breasts sag. Breasts start to sag as a woman ages, losing the muscle tone that holds them up. But not wearing a bra won't have that effect.
8. don't sweat nipple bumps. Small, pimple-like nipple bumps are common...and harmless. Called Montgomery's glands, they enlarge during pregnancy and breastfeeding.
9. If you're pregnant, your nipples will change. They will become noticeably darker and larger - nature's way of pointing the future baby in the right direction.
10. Nipple discharge is common. This is especially true in women with a fibrocystic condition, says Dr. Sandra Messner, a preventative oncologist at the Toronto Sunnybrook Regional Cancer Centre. Normal discharge can be straw-coloured or black, but see your doctor if there's any blood.
11. Breastfeeding can yield surprises. It can lead to tender, chapped nipples and blocked milk ducts - which can show up as hard lumps in the breast and armpit area.
12. Not all lumps are breast cancer. If you find a firm, movable lump in your breast, there's a high likelihood it's a fibroadenoma (a benign fibrous lump) or a fluid-filled cyst: both harmless conditions. To be safe, all lumps should be checked out by a doctor to rule out cancer.
13. Coffee and deodorant don't cause breast cancer. Coffee and deodorants causing cancer are just myths. A study in the January 2006 Journal of Cancer found no links between cancer and drinking coffee.
14. Watch lopsided breasts closely. Having one breast larger than the other is common. While the cancer link is yet unproven, a recent British study has made the connection.
15. Check your breasts when your period's over. The best time to check your breasts for changes such as lumps or to visit the doctor for a yearly breast exam is in the week after your period.
16. Feed your breasts well. A low-fat diet high in vegetables and fruit coupled with leaner meats and dairy products is optimum for breast health, according to the Canadian Cancer Society.
17. Routine mammograms pose a low cancer risk. The ionized radiation released during a mammogram is very low and the benefits far outweigh the risks, says Dr. Verna Mai, director of screening at Cancer Care Ontario in Toronto.
18. Breast cancer survival rates are higher than you think. The five-year survival rate is 86 per cent, says the Canadian Cancer Society.
19. Preserve your fertility. Breast cancer treatment doesn't necessarily mean you won't be able to get pregnant. Though radiation and chemotherapy can do a number on a woman's ability to conceive, cryopreservation, the process of freezing and storing embryos (fertilized eggs), is an option later.
20. There's no wrong way to check your breasts. According to awareness group Rethink Breast Cancer, making sure you examine your breasts regularly - whichever way you do it - is the key to tracking cancer.
21. Breast cancer statistics can be deceiving. The oft-told fact that one in nine women will develop breast cancer in her lifetime isn't as daunting as it sounds. One in nine is a lifetime risk, or cumulative risk, based on the assumption that a woman will live to 81.
