Intra-operative Radiotherapy For Women With Ductal Carcinoma in Situ Breast Cancer
Intra-operative Radiotherapy For Women With Ductal Carcinoma in Situ Breast Cancer
Whether the patients with low grade ductal carcinoma in situ breast cancer should accept
 radiationtherapy is uncertain.Radiation therapy uses high-energy x-rays to damage tumor
 cells. Giving radiation during surgery followed by external-beam radiation to the entire
 breast may kill more tumor cells.The clinical trial is conducting to find out the
 effectiveness of radiation therapy during surgery in treating women who have undergone
 breast-conversing surgery for low grade ductal carcinoma in situ breast cancer.
