The Breast Health Center offers support from the moment you are diagnosed with breast cancer and throughout your treatment and recovery.

Clinical Trials – Through partnerships with National Cooperative Groups John Muir Health participates in a number of clinical trials for new treatments of breast cancer. With prior arrangements, patients can be seen at the Breast Health Center.

Comprehensive Multi-Disciplinary Tumor Boards – The Tumor Board is a team of medical experts who review complex cases and make treatment recommendations. Consisting of experienced breast surgeons, plastic surgeons, gynecologists, medical oncologists, radiation oncologists, pathologists, radiologists and a genetic counselor, they focus their efforts on designing individualized treatment plans that will improve outcomes for each patient.

Genetic Counseling and Testing – A genetic counselor is available to conduct a detailed evaluation of a patient’s family history and, if necessary, recommend a genetic blood test to find out if you have a higher risk for developing hereditary breast cancer, which accounts for 5-10 percent of all breast cancers. If a patient is at risk, we will discuss prevention options to minimize your chances of getting breast cancer.

Multidisciplinary Pre-Treatment Conferences – We help you understand what treatment options are available, what to expect at every stage of your treatment, and which course of treatment would work best for you. 

Nurse Navigators – Throughout a breast cancer patient’s treatment, a Nurse Navigator is available to provide education, support and additional resources to help you overcome the challenges.

Additional services and programs we offer include:

  • Breast cancer resource library
  • Counseling and spiritual support
  • Physical therapy/lymphedema program
  • Nutritional counseling
  • Pharmacy services
  • Free wig fittings and wigs through The Wig Source.

Post-Treatment Survivorship Program – John Muir Health patients have access to a Survivorship Nurse Navigator who helps patients adjust to their post-treatment recovery.
