Study: Fellatio may significantly
decrease the risk of breast
cancer in women

(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 15,000 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 occurance of
breast cancer than those who had
not. There was no increased risk,
however, for those who did not
"I think it removes the last shade
of doubt that fellatio is actually a
healthy act," said Dr. A.J. Kramer
of Johns Hopkins School of
Medicine, who was not involved
in the research. "I am surprised
by these findings, but am also
excited that the researchers may
have discovered a relatively easy
way to lower the occurance of
breast cancer in women."
The University researchers
stressed that, though breast cancer
is relatively uncommon, any steps
taken to reduce the risk would be
a wise decision.
"Only with regular occurance will
your chances be reduced, so I
encourage all women out there to
make fellatio an important part of
their daily routine," said Dr. Helena Shifteer, one of the researchers at
the University. "Since the emergence of the research, I try to fellate at
least once every other night to reduce my chances."
The study is reported in Friday's Journal of Medical Research.
In 1991, 43,582 women died of breast cancer, as reported by the
National Cancer Institute.
Dr. Len Lictepeen, deputy chief medical officer for the American
Cancer Society, said women should not overlook or "play down" these
"This will hopefully change women's practice and patterns, resulting
in a severe drop in the future number of cases," Lictepeen said.
Sooner said the research shows no increase in the risk of breast cancer
in those who are, for whatever reason, not able to fellate regularly.
"There's definitely fertile ground for more research. Many have
stepped forward to volunteer for related research now in the planning
stages," he said.
Almost every woman is, at some point, going to perform the act of
fellatio, but it is the frequency at which this event occurs that makes
the difference, say researchers. Also key seems to be the protein and
enzyme count in the semen, but researchers are again waiting for more
The reasearch consisted of two groups, 6,246 women ages 25 to 45
who had performed fellatio and swallowed on a regular basis over the
past five to ten years, and 9,728 women who had not or did not
swallow. The group of women who had performed and swallowed had
a breast cancer rate of 1.9 percent and the group who had not had a
breast cancer rate of 10.4 percent.
"The findings do suggest that there are other causes for breast cancer
besides the absence of regular fellatio," Shafteer said. "It's a cause, not THE cause."
