40% less Cancer recurrence after Breast Cancer surgery if NO radiation treatment - Dec 2023

Compelling case for skipping RT in some early breast cancers - MD Edge

  • Recurrence rate: 1% in 5 years if no radiation therapy vs 1.7% if radiation therapy

  • "Omitting radiation therapy led to better health-related quality of life and functional and cosmetic outcomes, and the women viewed not having radiation as highly acceptable and appropriate treatment, not undertreatment."

  • Based on a study in Lancet: Postoperative radiotherapy omission in selected patients with early breast cancer following preoperative breast MRI (PROSPECT): primary results of a prospective two-arm study, which is behind a paywall

  • Vitamin D Life suspects that the radiation wounds the immune system, making it less likely to be able to fight off future cancers. Wonder if radiation decreases vitamin D levels on a long-term basis?
