Two significant studies presented at the San Antonio Breast Cancer Symposium highlight new approaches for treating early breast cancer, including ductal carcinoma in situ (DCIS). The findings suggest that active monitoring may be an effective alternative to surgery for low-risk DCIS patients, potentially reducing treatment burdens. Another study questions the necessity of lymph node removal in early breast cancer surgeries. Experts caution that longer-term research is needed to validate these findings before changing standard treatment practices.
