Proton Therapy for Breast Cancer

Because proton radiation deposits its highest doses in diseased tissue, nearby organs, such as heart, lungs, and bone, are less likely to receive radiation. This is especially important for breast cancer patients, who may face the risk of secondary cancers, lung injuries and major cardiac events later in life due to previous radiation exposure.

Proton therapy’s accuracy is even further enhanced by Scripps’ advanced imaging and pencil beam scanning technologies, which focuses a narrow proton beam — smaller than the width of a pencil — to precisely target tumors.

Breast cancers treated with proton therapy

  • Early stage breast cancer
  • Locally advanced breast cancer (Stage II and III)
  • Ductal carcinoma in-situ
  • Triple-negative breast cancer

Support services

Cancer treatment can be a difficult time for both patients and their families. Understanding this, Scripps offers a wide variety of care to ease the burden. Learn more about the support services available for breast cancer patients.

What to expect

Each patient’s therapy is precisely tailored to their needs. Patients and clinicians collaborate closely to create a personalized treatment plan. The number and length of treatments will vary, based on the cancer. How patients respond depends on many factors, including the types of treatments they are receiving. Many people tolerate proton therapy well and continue to perform normal activities. However, individual responses vary.

Proton therapy is a highly precise form of external radiation therapy that can be used for tumor control in select patients. All cancer treatments have advantages and disadvantages. Be sure to discuss these, as well as treatment options, with your cancer specialist.
