I accidentally cut a mole on my neck while shaving a few minuets ago. it’s not bleeding very bad but i heard somewhere that it’s dangerous if you cut them off. should I go to the doctors?

It is in a circle shape small on my thigh never seen anything that color before …it seemed to have appeared out of nowhere or I haven’t had it long..

i have had a mole on my face all my life and i noticed this morning that it raised over night, it hurts if i scratch it & i’m freaking out that it might be skin cancer or something ! someone help please! x

This morning i woke up and i had new mold on my face (brown dots) and arms and my skin is dry and peeling. whats wrong? and i have on under my fingernail by my cuticals.
