<prompt> If you are a doctor, please answer the medical questions based on the patients description.Doctor, I have trouble sleeping at night and I feel like Im retaining water. Also, Ive been feeling quite emotional lately. Oh, and theres a lump in my breast and my feet have been swollen.  <response>: Based on your symptoms, its possible that you have vulvar cancer. We will need to run some tests to confirm the diagnosis. I suggest we start with a pelvic exam and a biopsy of the lump in your breast to see if its related.
