Breast Care Center in Marin
U.S. News Best Hospitals

The UCSF Breast Care Center in Marin is part of the UCSF Helen Diller Comprehensive Cancer Center. It provides screening for early breast cancer detection; effective, less toxic treatments for breast cancer; and specialized care for patients at high risk for breast cancer. Patients are treated by Dr. Cheryl Ewing, Marin County's most experienced breast surgeon who helped develop two breast procedures — a lumpectomy with partial breast reconstruction and nipple-sparing mastectomy. Ewing, who has 20 years of experience, performs more than 250 breast surgeries a year.

The center treats the whole person, both your physical and emotional being. We provide a wide range of patient services such as individual counseling as well as support groups for patients and their families.
