The father’s age, however, did not affect the daughter’s subsequent risk for breast cancer, leading the researchers to speculate that the effect may be caused by exposure to higher levels of estrogen in the womb.
Higher incidence of breast cancer is more consistent in firstborn daughters who also have estrogen- and progesterone-positive tumors. Intrauterine exposures, especially those related to maternal endogenous sex hormones, may play a role in the etiology of breast cancer.
October is breast cancer awareness month. This is a time when women come together to support and comfort each other through the disease that affects millions of women worldwide.
So this month, all the people must unite for their grandmothers, mothers, sisters, aunts, cousins and friends who are fighting the deadly disease.
