Not a teacher, paediatric nurse...Im 2 months post final radiation this month and to be honest, I'm getting bored. I thought Id give myself the whole year but I realistically think Ill probably go back part time this month. I guess since you don't know your full treatment plan its difficult, but my skin was fully recovered 4 weeks after radiation and I could wear a bra and top again..you might be cutting it fine to get back to school for term one. However many people do work full-time through radiation, it is much much easier generally than chemo. I could have worked but didn't want to.
