AGE AND PHYSICAL RISK FACTORS IN BREAST CANCER

The following article includes pertinent information that may cause you to reconsider what you thought you understood. The most important thing is to study with an open mind and be willing to revise your understanding if necessary.

Age is probably the most important general factor associated with the risk of breast cancer. Increase the risk of breast cancer in older post-menopausal population. For this reason, any breast cancer screening recommendations are based on age. Obesity, however, the only one of the most avoidable risk factor associated with breast cancer. With the dramatic increase in obesity in the United States, this may be the number one reason for the persistently high incidence of breast cancer. Other physical factors also play a role in some of the risk of breast cancer. Including high, body shape, breast size, and mammographic density. This is the physical factors summarized below.

Body weight and breast cancer: a female body weight did not influence the risk of breast cancer, but the effect is different for premenopausal and postmenopausal breast cancer. Most studies have found that heavier women (weighing more than 175 pounds) is lower than the risk of breast cancer before menopause and a higher risk of breast cancer after menopause, compared with thin women (weight less than 130 pounds). Since 80% of breast cancer after menopause occurs, the negative effects of obesity far outweigh the positive effects. The result is the same regardless of body weight is examined directly, or if the body mass index used to adjust the height of the effect on body weight.

You may not consider everything you just read to be crucial information about . But don't be surprised if you find yourself recalling and using this very information in the next few days.

The shape of the body and breast cancer: Some human studies have found that women who for more of their body fat in the stomach (apple shaped) is higher than postmenopausal breast cancer compared with women with more of their body fat around their hips (pear shaped) . This seems to be true without the woman body. Relationship between the location of the fat in the body and the risk of premenopausal breast cancer is not clearly defined

Elevation and breast cancer: a woman height has been associated with breast cancer risk in different studies. Taller women (5'9 "or higher) are slightly increased risk of premenopausal and postmenopausal breast cancer than women with a shorter (5" 3 "or less). Someone from a height determined by the interaction between genetics and nutrition. How high can influence on breast cancer risk is unclear.

Breast prostheses size and breast cancer: There is a belief that a small chest with a low risk of breast cancer. This theory was used to explain why women with breast implants have a lower risk of breast cancer. Most studies found no association between breast size and breast cancer risk. A study, but found no increase in risk of breast cancer in women with larger breasts lean. In this study, more than 4000 women who were grouped according to bra size before birth
. Women who are lean (chest size of less than 34 inches) and have a larger chest (size B, C cups or more) of a high risk in post menopausal women with breast cancer with breast cancer or smaller cup size. Women with a breast size has no correlation between breast cup size and breast cancer risk. More research is needed to confirm the results

Mammographic density: Several epidemiological studies have shown that breast density measured on mammograms is an important risk factor for breast cancer. The risk of breast cancer associated with the highest density category was estimated at more than the lowest density category. Mammographic density appears to be input for the development of invasive cancer after DCIS (ductal carcinoma in situ). Increasing density is associated with an increased risk of breast cancer in both premenopausal and postmenopausal women, the consequences for the survival of ten years after mammography. Mammographic density has also emerged as risk factors for breast cancer in women with a family history of the disease. Mammographic density may be important, even in patients positive BRCA gene. In fact, May mammographic density much heritable component.

Now might be a good time to write down the main points covered above. The act of putting it down on paper will help you remember what's important about .
