I am reaching out to discuss treatment of DCIS across the pond. I was diagnosed with stage 0 high grade on my left side. Had a lumpectomy 6 weeks ago with clean margins. Radiation has been recommended to prevent a recurrence. I am very concerned about radiation to my heart as I am in my 60s and have a family history of heart disease. I heard about a different form of radiation, Proton therapy, that controls depth and stray beams to better protect the heart and adjacent areas. It isn't widely used in the States yet and there is little data I can find on it's efficacy for breast cancer. Has anybody had or investigated Proton radiation?
Thank you in advance
