Bump on foreskin

ive had this bump on my foreskin for as long as i can remember, Ive never had it examined but i plan on seeing a dermatologist soon. i think its a wart but not 100% sure. its almost like an air bubble .

looks more like a cyst than a wart

any advice to treat it ?

its either a cyst or lymphocele due to that fact u say u have had it for a while in most cases a cyst would need to be removed surgically and a lymphocele drained it could be either i would go to the doctors there are some other methods without surgery if its a lymphocele it usually involves manually trying to rub the lump as its just lymphatic fluid under the skin normal caused by rough and over masturbation or sex but i would speak to a doctor before attempting that
