Mole on left side of back checked by Dermatologist advised removal of same with extended area around. Area removed for histology checks revealed it to be a malignant melanoma. The dermatologist then refered me to another consultant. Lymph nodes were checked under my left arm pit as possible problem. CT Scan & Ultra Scan with biopsis were carried out.This resulted in a " dissection" of the lymph nodes under my armpit & also removing a larger area on my back from the original site of the melanoma. 3.5 days in the centre. Drain for fluid attached for 6-7 days then removed. After approx' 2-3 weeks fluid built up under the arm becoming very uncomfortable & a return to the consultant to be drained by needle & syringe resulting in 900mls. being removed. Making things a bit more comfortable. now a week later & the fluid is starting to build up again. Consultant has also suggested a PET Scan & MRI Scan also. Will the fluid need draining again later & continue to drain or not? What next after scans , Oncologist & treatment. Any advise please. Regards Jeff
