Women with Benign Biopsies may still be at Risk for
July 21st 2005
Not all benign breast lumps are the
same. Most women that undergo a breast biopsy will be told their lump
is benign. Researcher in the New England Journal of Medicine compared
different types of benign tissue in women. Some benign biopsies
resulted in higher risks than others.
The researchers identified 9087
women who received a benign breast disease diagnosis from the Mayo
Clinic between the years 1967 and 1991. Of the 9087 woman diagnosed
with benign cells, 707 developed cancer within the next 15 years. They
compared the incidence of breast cancer with the expected incidence.
From this data the risks were estimated.
Two-thirds of the women studied had
lumps made up of cells that were not growing. In this group the risk for
developing breast cancer did not increase over a ten year period.
Some of the women in the study had
actively growing benign cells. Even though the cells were growing they
were still considered benign. About 4 percent of the cells were
atypical and growing, but still considered benign. These cells are
important to identify because they elevate the risk of developing breast
cancer. Close monitoring is needed in these cases.
Mammograms are the first line of
detection. The American Cancer Society recommends a mammogram once a
year for women over the age of 40. If a lump is discovered, it is
important to confer with your doctor on the best course of action. Even
if the lump is benign, more frequent screening may be recommended.
About 1 million women in the US will
be diagnosed with a benign breast disorder this year. The vast majority
of the disorders will be a benign cyst. Earlier studies found that
women at higher risk were 56 percent more likely to develop breast
cancer within 15 years. One of the primary risk factors is family
