That sounds like a very worthwhile but very specialized/expensive procedure. I'm going to ask tomorrow if they offer that or where I might go to get it done. I've always been under the impression that you couldn't really test for HPV in men but I guess that's not entirely true
Actually, a biopsies are pretty routine. If you're going to your campus health clinic, it should be covered by your student fees. I never had a wart biopsied in college, but they did take off some moles and check for malignancy.
Another suggestion would be to go to a STD clinic. Most of them are very reasonable price-wise, and some have sliding-scale fees -- i.e. if you havae no income, you don't pay for treatment.
