About 15%?[3-15]of breast cancers are inherited
Approximately 80% of hereditary breast cancer is
caused by mutations in the BRCA1 or BRCA2
genes.P53 has a role too
Women who inherit a BRCA mutation have a 50%
to 85% chance of developing breast cancer in
their lifetime
Women with especially strong family history may
consider preventive surgery to remove breast
tissue and/or chemoprevention
Several other genetic syndromes can increase
breast cancer risk

5. PATIENT`S PREFERENCE
Sentinel node biopsy is a technique
which helps determine if a cancer has
spread (metastisized), or is contained
locally. When a cancer has been
detected, often the next step is to find
the lymph node closest to the tumor site
and retrieve it for analysis. The concept
of the "sentinel" node, or the first node
to drain the area of the cancer, allows a
more accurate staging of the cancer,
and leaves unaffected nodes behind to
continue the important job of draining
fluids. The procedure involves the
injection of a dye (sometimes mildly
radioactive) to pinpoint the lymph node
which is closest to the cancer site.
Sentinel node biopsy is used to stage
many kinds of cancer, including lung
and skin (melanoma).
