The average woman
has a 10 percent risk of getting breast cancer in her lifetime. Add a strong
family history of the disease, and the risk rises to nearly 80 percent.
Doctors believe they've found a way to reduce those numbers with a simple
nasal spray.
Inside
is a drug called deslorelin. Jeffrey Weitzel, M.D., an oncologist at the
City of Hope Cancer Center in Los Angeles, Calif., believes it will make
mammograms easier to read.
The spray works by shutting
down the production of estrogen. Dr. Weitzel says, "It's a medicine that
shuts down the ovary, sort of a medical menopause."
The goal is to make mammograms
easier to read, but doctors believe decreasing a woman's exposure to
estrogen may do much more. "We fully expect that their breast cancer
risk will go down. They'll be less likely to develop breast cancer
and possibly even ovarian cancer," says Dr. Weitzel.
So far, Brandy shows no
sign of the disease that killed her mother and grandmother. If the spray
works, it's possible
she never will.
Doctors say if it works it may someday
be used for women with a moderate risk of breast cancer and as a simple
contraceptive. So far, studies show women on the drug are able to conceive
children later. Dr. Weitzel says there are
no significant side effects from the drug.
