Obesity and breast cancer

Female breast cancer and obesity and high-calorie diet, weight control and adjust the diet to prevent breast cancer can not be ignored.

Overweight and obese women suffering from breast cancer significantly increased the risk. Especially after menopause can increase the risk of 4.51-12.38 times. Women with abdominal obesity was mainly spindle-to hip, thigh fat was the main type of pear. American scholar of 216 breast cancer patients, found that waist-to-hip ratio of greater than 0.77, the relative risk of breast cancer than 3 times higher than normal, the ratio of greater than 0.8, the relative risk than normal 6 times as high. Women's hip and thigh fat is not easy to eliminate, but relatively speaking, breast cancer and cardiovascular disease less affected. Abdominal obesity, on the contrary, although it easier to eliminate, but cardiovascular disease and breast cancer have a greater potential hazard.

Obese women suffering from breast cancer, axillary lymph node-prone. U.S. researchers recently confirmed the 656 invasive breast cancer patients found that a thin woman, 33% of axillary lymph node metastases, and who are obese have 66%. Obese women suffering from breast cancer, the relative effectiveness of the operation was not so satisfactory, the recurrence rate was also higher than non-obese.

The incidence of breast cancer, development and estrogen, the body fat of women in addition to ovarian estrogen secretion, there adipose tissue can be generated considerable estrogen, estrogen, the higher the level of the more susceptible to breast cancer.

Long-term intake of high calorie diet lead to overweight and obesity. Often eat fried or deep-fried food, the risk of breast cancer increased 1.6 times. Shanghai had 537 patients with normal-control study and found that fat intake more than those who suffer from the relative risk of breast cancer increased 2.72 times that of postmenopausal women more than fat intake, increasing the relative risk of 3.53 times. Less activity, due to the relative excess heat, the incidence of breast cancer has also increased accordingly. Investigation showed that the women's movement did not occur the risk of breast cancer than those who sports a high 1.86 times.

The type of fat and breast cancer close. Canada diagnosed with breast cancer and scholars of the 666 female patients, their investigation confirmed the previous year's intake. It was found that the intake of animal, the more unsaturated fatty acids, the more prone to lymph node metastasis, and the plant's intake of unsaturated acid does not have this phenomenon. Acid intake of saturated up to a group of 51% of lymph node metastasis. At least a group of only 41% of lymph node metastasis. It would appear that in older women to eat less animal fat and vegetable oil replace it with an appropriate, prevention and treatment of breast cancer and coronary heart disease as a whole.
