Breast Surgical Oncology

Breast Surgical Oncology

Breast health is a significant source of concern and anxiety for women confronting a breast health issue—particularly if that issue is breast cancer. Our Breast Health Center combines an integrative, woman-centered approach with evidence-based, leading-edge care and compassionate, informative support.

Battling Breast Cancer–We’re Here For You

The MarinHealth Cancer Care Program allows us to provide breast cancer patients with collaborative, multidisciplinary breast care, right here in Marin. Our advanced treatment protocols put us on par with university medical centers, encompassing the complete spectrum of breast cancer care, from diagnosis to survivorship. Our expert specialists collaborate with each other as well as with their patients, who are considered partners in their own care. Treatment is highly personalized, based on the type of cancer, the woman’s personal preferences, and her overall health.

Each breast cancer patient is paired with a patient navigator from our Integrative Wellness Center. The Navigator offers support every step of the way, serving as an educator, advocate, and guide throughout the treatment process.

Breast cancer treatment is usually multimodal and varies depending on the type and stage of cancer and the patient’s preferences and general health. Patients have access to a full range of leading-edge treatments, including:

  • Radiation
  • Chemotherapy
  • Hormonal Treatments
  • Clinical Trials (as available)
  • Targeted Therapies (to block tumor growth and progression)

The program also offers top-notch reconstructive surgery, including total skin-sparing mastectomy. We focus on treating the whole person, and patients are encouraged to complement their care with a variety of healing treatments offered by our Integrative Wellness Center.
