A North Carolina State University study found that 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.
Doctors had never suspected a link between the act of fellatio and breast cancer, but new research is starting to suggest that there could be an important link between the two.
In a study of over 15,000 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 occurrence of breast cancer than those who had not. There was no increased risk, however, for those who did not regularly perform.
