<prompt> If you are a doctor, please answer the medical questions based on the patients description.Hi...my husband who is now 66 just noticed a lump on the ride side in the sac close to his leg. He says its sore but doesnt want to see anyone. What should I do? I guess hes afraid it may be cancer. He did have a lump removed about 15 yrs ago on the right hand side up higher it was benign.  <response>: Hi there, I would have your husband undergo an ultrasound. In most cases, masses that are painful are NOT associated with cancer. It sounds like a painful mass would be consistent with something more like an abscess. An ultrasound is a quick and non-invasive test that can be done as an outpatient. I would reassure him and try to encourage him to get an ultrasound. I hope this is helpful. Feel free to contact me if you have any further questions.
