Risk reduction
Your doctor may recommend ways to
lower your risk for breast cancer based
on your risk, general health, and other
factors. This is called risk reduction.
Three methods are used, which are:
Lifestyle changes
Changes in your lifestyle may reduce your chances
of developing another breast tumor. Examples
are eating more healthfully, exercising more, and
achieving a healthy body weight. Your doctor can
suggest lifestyle changes that are specific to you.
Hormone therapy
The second risk reduction method is taking hormone
therapy drugs. Female hormones help some breast
cancers grow. Thus, taking drugs that lower the
amount of female hormones in your body or drugs
that stop hormones from working may help. Not all
women with LCIS should take hormone therapy. Your
doctors can let you know if hormone therapy is right
for you. The drug used may differ between women
who get menstrual periods and those who don’t.
Although hormone therapy lowers breast cancer risk,
it can cause hot flashes, cataracts, leg cramps, blood
clots, and other cancers depending on the drug. Ask
your treatment team for a complete list of side effects.
Your doctor may also know about research studies of
hormone therapy or other drugs that you can join.
The third method of risk reduction is surgery. Surgery
is mostly done among women at high risk for breast
cancer. One surgical option is a bilateral mastectomy,
which is the complete removal of both breasts.
A total mastectomy removes all breast tissue but
no lymph nodes or chest muscles. Following the
mastectomy, or in some cases at the same time
as the mastectomy, you may want to have breast
reconstruction. See page 29 for more information.

Figure 4. Excisional biopsy
During an excisional biopsy,
the whole tumor with some
normal-looking tissue around
its edge is removed using a
surgical knife. The normal-
looking tissue at the edge of
the removed tissue is called
the surgical margin.
