Breast cancer and mushroom intake:
Mushroom intake and the risk of breast cancer:
A case control study of 362 Korean women aged 30-65 years reported an association between mushroom consumption and decreased risk of breast cancer. Comparing the women who ate the most mushrooms against the women who ate the least mushrooms, mushroom eaters had 48% reduced risk of developing breast cancer. When the data was broken down by menopausal status, the effect was far more dramatic. The postmenopausal mushroom eaters had an 84% decreased risk of breast cancer. (13)
Mushroom consumption in premenopausal women may have a protective benefit against breast cancer. Mushroom consumption and risk of breast cancer were analyzed in 358 breast cancer patients and 360 cancer-free individuals. Comparing premenopausal women who ate the most mushrooms against the women who ate the least mushrooms, mushroom eaters had a 65% reduced risk of developing breast cancer. When the data was broken down by estrogen receptor status, the effect was stronger (70% risk reduction in women with estrogen receptor (ER)+/progesterone receptor (PR)+ than those with ER-/PR- tumors).
