I need to write about melanoma symptoms, diagnosis, treatment (skin cancer) but i also have to put the normal functions of the integumentary system plzzzzzzzzzzzzzzzzzzzzz help me make a thesis of this!!!thank you

It started as a big freckle then i picked it off, and now it wont stop bleeding and now there is a scab there and if i try to pick the scab off it will bleed even worse. i am really worried and scared now. I am 14 and i dont want to die of cancer i put a hello kitty band aid on it with Neosporin and i hope it helps, ty <3

I have been diagnosed by the doctor as having an anal skin tag. However, this is causing me pain and discomfort, as well as producing an unusual discharge that is orange/pink. It also bleeds sometimes. Is this normal for a skin tag, or would it best if I went to another doctor for a second opinion? I am also worried it might be cancer…. Any help would be greatly appreciated!
