Breast Cancer - Carcinoma in Situ
, Version 1.2016
If you likely have hereditary breast cancer, your
doctor will refer you for genetic counseling. A genetic
counselor is an expert in gene mutations that are
related to disease. The counselor can tell you more
about how likely you are to have hereditary breast
cancer. He or she may suggest that you undergo
genetic testing to look for gene mutations that
increase your chances of developing breast cancer.
Hereditary breast cancer is most often caused by
mutations in the
genes help to prevent tumor growth by fixing
damaged cells and helping cells grow normally.
Genetic testing can tell if you have a
another mutation. Your test results may be used to
guide treatment planning.
Some abnormal changes in genes, called VUS
ignificance), are not fully
understood by doctors. Your doctors may know of
research that aims to learn more. If interested, ask
your doctors about taking part in such research.
