How long does radiation last after lumpectomy for DCIS?

I am a year out from lumpectomy for stage zero. Had 4 weeks of radiation therapy afterwards. My “DCisionRT” results showed i would benefit. Also saw a benefit when i did the Sloan Memorial Kettering “calculator.” I had some dermatitis the last week of radiation but it went away quickly. I still have occasional tenderness in the area and the upper arm muscles sometimes get sore after i exercise with heavier weights. Seems better than it was right after treatment. I think the radiation was worth it given how much it could reduce the risk of recurrence. Ditto for endocrine therapy.

Radiation treatment duration can vary based on individual factors, but many patients find it helpful to know that typical courses range from a few weeks to several months, with daily sessions being relatively short. It's completely understandable to feel anxious about radiation while feeling confident about surgery - many community members share similar feelings about different aspects of their treatment journey. Consider preparing a list of specific questions about the radiation process, timeline, and what to expect for your follow-up appointment, as having detailed information often helps reduce anxiety about upcoming treatments.
