Proton Therapy Treatment for Breast Cancer
The breast cancer tumor usually occurs in the lobules and ducts of the breast, which are used in the production and delivery of breast milk. Breast cancer is the most common cancer among women aside from skin cancer. Men are also susceptible to breast cancer, although the disease is rare among males.
As with other cancers, the best possible outcomes for breast cancer treatment come through early breast cancer care.Proton therapy has unique attributes that reduce radiation exposure to normal, healthy organs.1,2 This is especially important in left-sided breast cancer, as the cancer is close to critical organs such as the heart and the lungs.

Clinical Benefits of Proton Therapy
- 88% less radiation dose to the heart for left sided breast cancer.1,2
- 44% reduction in clinically significant radiation doses to the lung.2
- 90% of partial breast irradiation cases result in good to excellent cosmetic outcomes at 5 years.3
- Well tolerated – Less than 4% serious side effects (grade 3) in locally advanced breast cancer.2
