27 year old lobular carcinoma

I too had an axillary clearance - several very suss looking nodes and the biopsied one was malignant. Turned out it was the only malignant one but it was a fair call. Mobility was fine right away, no pain, no scarring. Still a degree of numbness which presumably is there for life, but affects nothing  - I don't wax but if I did I would need to be careful as I still can't distinguish hot and cold in one armpit well enough. Lymphoedema is a scary thought, doesn't always happen and can be very manageable (don't Google that one, will give you nightmares and mainly unjustifiably). Anticipating all these things appears like a way of planning, but remember they may never occur, and the anticipation may just cause you unnecessary worry. Take one day at a time, things will get much clearer when you know more precisely what you are dealing with. Best wishes.
