I get imaginary cancer with some regularity. Just went into remission last Tuesday, yet the doctor said even though it isn't cancer I should be in for an MRI in 6 months because the way my tissue is formed I'm at an elevated risk and I'm at a high risk due to genetics. It's hard to ignore the lumps, even when told they are benign cysts.

In your case I would get a second opinion. Be frank about your current doctor's comment and concern about your DHEA. Perhaps your doctor suffers from some incompetence in this area as (S)he does in bedside manner.

It's not uncommon for a doctor to now know what the heck is going on with a patient. This doesn't mean something terrible is going on, just that your doctor is clueless with the situation. Many doctors want you just to accept this, but there is no reason to if you don't feel comfortable with the "answer" you've been given.
