AP -- Women who perform the act of fellatio and swallow semen on a regular basis, one to two times a week, may reduce their risk of breast cancer by up to 40 percent, a North Carolina State University study found. Doctors had never suspected a link between the act of fellatio and breast cancer, but new research being performed at North Carolina State University is starting to suggest that there could be an important link between the two. In a study of over 15, women suspected of having performed regular fellatio and swallowed the ejaculatory fluid, over the past ten years, the researchers found that those actually having performed the act regularly, one to two times a week, had a lower occurance of breast cancer than those who had not.
