@A MyBCTeam Member I completed chemo in June and had to take a 4 week break due to lung issues before I could start 6 weeks of radiation.

Mu surgeon had me schedule my lumpectomy for 4-6 weeks after my last chemo, to give my body some time to heal. I had it exactly 4 weeks after my last chemo. After the results from the lumpectomy, I met with a radiation doc to discuss my options. So, I think it was another month or so after my surgery that I started my radiation treatments; 8-9 weeks total. I probably could have started sooner, but had a slight complication. I had to get another mamma, as my surgeon thought the biopsy clip may not have been removed and they wanted to know that prior to starting the radiation. In fact, it had not been removed, but had no bearing on the radiation treatments, so I was able to start after that. You probably can start sooner, but I think your docs will recommend at least 4 weeks.

How long should you wait between finishing chemotherapy and starting radiation therapy?

Radiation treatments typically begin 4-8 weeks after completing chemotherapy. This timing allows your body to recover from chemotherapy before starting the next phase of treatment. The specific schedule will be personalized based on:
• Your overall health condition
• The characteristics of your breast cancer
• Whether the cancer has spread to lymph nodes
• Your individual treatment goals

Before starting radiation, discuss with your radiation oncologist if there are any special preparations needed, such as avoiding certain supplements containing antioxidants (vitamins A, C, D, and E).
