Hi, I have been sent by my gp for urgant tests as I have a swelling under left armpit this seems to be growing and then going down but not fully and making my arm go numb, im 32 and everyone says oh it's not likely because of your age, I feel like I'm in a really scary limbo waiting and not sure what to do or think.
My question is I dont have a hard lump does it necessarily need to be hard to be cancer?
