I have recently had chemotherapy for non Hodgkin s lymphoma . My last cycle of r-chop was in September . My illness was predominantly in my chest, underarms and neck. I have just found a marble size lump in the top right underarm but I was given the all clear in October after a PET scan . Should I be worried or do you think it could be menopause related. I m 44 but the doctor said I m having the menopause early due to the treatment. Many thanks claire
You should closely observe your marble size lump in your underarms in consultation with your treating Doctor.  Sometimes it can be a residual node with necrotic tissue or granuloma which may not be of any consequence. However, we might need a biopsy procedure if this node does not resolve in few months time. It is not in any way related to menopause.
