3-5 weeks: Biopsy should be done soon after a suspicious lump is detected either by physical examination or mammogram. If it is cancer or dcis, a lumpectomy should follow anywhere from a few days to a few weeks later. The start of radiation depends on healing after lumpectomy, but radiation generally starts about 4 weeks later. Radiation generally takes 6-7 weeks to complete.
