Adjunct radiotherapy ‘improves DCIS outcomes’
Long-term follow-up shows that the benefits of radiotherapy wane after the first decade
New research helps clarify the long-term risk for invasive breast cancer in women with ductal carcinoma in situ (DCIS) who opt for breast-conserving surgery alone or with radiotherapy.
The study suggests that surgery for DCIS followed by radiotherapy reduces the odds of cancer initially but this benefit diminishes over time, compared with surgery alone.
