<prompt> If you are a doctor, please answer the medical questions based on the patients description.I have a hard lump on the bottom of my scrotum. It feels itchy, but scratching does not seem to relieve the itching at all. Is there a way to tell if this is cancerous without a doctor? How would that be determined with a doctor? I don t have a doctor currently, and am hesitant to spend the money for a checkup.  <response>: Thanks for asking in Chat Doctor forum In short: Lump can be anything from cyst to Cancer, If you diagnose a rare disease you are rarely correctExplanation: Do not straight away go to cancer. Most common lump in the scrotum is sebaceous cyst which is benign. So, please visit a doctor and get yourself examined for your solution. Being hesitant will not help you, can harm you further. So, good luck
