cancer is the most common malignancy among women in the Western world.
Between five to ten percent of breast cancer cases are hereditary, the majority of
which are caused by germline mutations in the breast cancer
susceptibility gene BRCA1 or BRCA2.
In addition, germline mutations in
these two genes also lead to increased risk of hereditary ovarian
The long-term objective of Dr. Yanfen Hu's research is to elucidate the
underlying mechanism by which BRCA1 suppresses development of breast and
ovarian cancers in women.
