Found lump under armpit, GP appointment booked, what to expect.

[LumpyArmpit]

as the title says, I have found a lump under my armpit. It is hard, does appear to move slightly under fingers and is a little tender.

The last couple of weeks, I’ve also had night sweats. I put this down to illness (suspected food poisoning), my period coming on (although sweating not regular) and one night of alcohol over the weekend.

Ive also lost quite a bit of weight since new year. I’ve been actively wanting to lose weight, have been watching what I eat, cut out most alcohol but haven’t been starving myself or increased my activity. I’ve lost about 1 stone in the last 8 weeks. Have been trying to shift this weight for a number of years so the ease and speed has concerned me.

I have a GP appointment booked for Friday, but have woken up today spiralling. What should I expect from the GP appointment? Has anyone had similar and it turned out to be just a lymph node or something else not sinister?

i've had several relatives with it, and because of genetic predisposition i get tested regularly. Both mom and her mother have it.

Once you're on the meds it resolves very quickly. Mom just has to have bloods once a year to check her levels to see if they need to adjust her meds at all.

Is there any update on this? I have exactly the same except got booked for a blood test and not a breast clinic which makes me even more paranoid that they're not checking 😞
