I had a selective neck dissection on 8/13. Pathology revealed only 2 positive lymph nodes, but I must have radiation starting about 9/24. I am a high school teacher and need to know how long I can still teach once radiation of the neck begins. I have read so much about loss of salivary glands, sore throat, mouth sores, burned skin, etc.... The supervisors need an idea of when i will start feeling too awful to teach so they can prepare for a lone term substitute...The radiation will be 6 to 8 weeks. How soon after the treatment ends will I be able to return to work ??? HELP please with any info. Thank-you
