Hello. These are caused by the human papilloma virus, though there are many different types of this virus. There is no cure for the virus but the bumps can be treated symptomatically and because they are growing and because they are a concern to you, I would suggest that you seek treatment for this. The removal of these growths can be done with over the counter aids, however, these are slow to work and depending on the sizes of your growths, it may be better advised to have a dermatologist remove them. They can do so with a quick freezing procedure (which some patients report as slightly painful, however, it is done in one visit) or by using a chemical which will have to be repeated over several visits. Though the dermatologist that you saw in 2001 was correct that there is not a cure for this, they were incorrect in saying that there was no treatment. I advise you to see another dermatologist for the removal of these growths for your own peace of mind.
