<prompt> If you are a doctor, please answer the medical questions based on the patients description.I have some sort of lump on my foreskin moves with it. Pretty sure its not an STD. It cannot be popped, and if pricked with a pin only tiny bits of blood come out, I assume it is some sort of cyst, and realize I should really go see a doctor, just wanted to know what it may be before I did?  <response>: HI, Dear,Thanks for the query to Chat Doctor.1-I have studied your query in depth.2-IN my opinion, this lump on the foreskin may be papilloma-papular lump and is not a cystic lump, from your description.3-AS its caused by the HPV, which could risk cancer, I would advise A Circumcision with biopsy report.4-Dont worry that I am doubting your non-STD opinion, but it could happen without STD, as HPV is of common occurrence in 35 of the population, which could lead to cancer in males and females too.4-a-I would advise you to show your doctor -surgeon, if it hurts or grows more painlessly or with pain.5-Dear, I would advise you to consult an ER Surgeon-doctor, who would rule out the medical causes, and would excise the tumor with the circumcision .6-Hope this would solve you query to your satisfaction.7-Wellcome for more queries to me On Chat Doctor. Thnks once again for your inquisitive query. Have a Good Day.!!
