Obesity and postmenopausal breast cancer

July 4, 2008

Obesity increases the risk of breast cancer in postmenopausal women. Upper body weight accumulation tends to be particularly hazardous. (International Journal of Epidemiology 28:1026-1031, 1999)

Mammographic patterns and breast cancer

July 1, 2008

J. N. Wolfe established four mammographic patterns based on the amount of fat, connective and epithelial tissue in a breast. Women in two of the four categories are considered to be at increased risk of breast cancer.

Researchers from Great Britain studied the effect of diet on these mammographic patterns. They observed that women with high intakes of carbohydrate and total protein were more likely to have the pattern associated with the risk of breast cancer. They observed that total meat consumption was strongly associated with high risk in post-menopausal women.

Earlier studies have shown that a high saturated fat intake increased the risk of mammographic high risk patterns, while carotenoid and fiber intake lowered the risk. (British Journal of Cancer 83(1)121-126, 2000)

Exercise, weight gain, breast cancer

July 1, 2008

While some studies have reported a reduced risk of breast cancer with exercise other studies have not found this. A study of almost 5,000 women suggests that those who exercised vigorously during their early life were at reduced risk of breast cancer if they did not gain — or gained very little — weight during adulthood.

Breast cancer surgery

June 20, 2008

The timing of surgery for breast cancer may impact the survival rate according to a study from Guy’s Hospital in London. They observed that surgery performed before day three or after day 12 of the menstrual cycle increased the survival rate in premenopausal women.

Over 100 breast cancer patients were followed over a ten year period. Those whose surgery had been performed during the luteal phase (the last two weeks of a woman’s cycle) had a 75 percent survival rate; those whose surgery was done during the follicular phase (between day three and twelve of the menstrual cycle) had a survival rate of only 45 percent.
