Delay Starting Radiation



Is there any danger in postponing radiation for three weeks after the completion of chemo? I had a stage 1 Her positive tumor with no lymph node involvement. I am scheduled to take a vacation two weeks after I complete Chemo and I want to start radiation after I get back. I will be gone one week. My oncologist wants to start immediatelywith no interuptions.


We generally start radiation 3-4 weeks after last treatment with chemotherapy. Up to 6 weeks is usually ok if the tumor was completely resected with clear margins. Perhaps you could meet now with the radiation oncologist to get a second opinion.
