Hi, I am a 63 year old AKA .i have a rapidly growing spot on my amputated stump. It’s been 6-7 months since I noticed it. It is a hard , scaley bump that is growing upwards. It hurts to touch it and I have noticed that when I am carrying something between my legs, like a glass, it hurts and now it aches around the spot for a long time when I bump or rub it . Thank you for you’re help.
