When do you need radiation for the treatment of ductal carcinoma in situ?

ANSWER

After lumpectomy, radiation significantly reduces the likelihood that the cancer will come back. If cancer does return, it’s called recurrence. Radiation can be given to the entire breast, or it can be taken internally to target certain areas of the breast.

Some women with an extremely low likelihood of cancer recurrence may have a lumpectomy only. This may be an option for older women with small tumors whose surgery showed large amounts of healthy tissue on all sides of the cancer. Discuss the risks of not having radiation with your doctor before deciding against it.
