im barely 14 and i cant tell if i have cancer or if its just a pimple but i dont think pimples bleed with a fluid and then white stuff comes out in between the middle of your chest.
Pimples are often seen on upper chest, or back. The large ones may contain pus, or may bleed on applying pressure. Stop worrying so much, it's not cancer. If your ACNE is so troublesome see a dermatologist or a homeopath.
