Hi,
Are you sure that this is not a simple haemorrhoid?
I'm glad you are getting this looked at, if only to give you piece of mind.
Yes, HPV does cause anal cancers. I have come across 1 male who did have a recurrence of his head and neck cancer in the anal area. Though he had extensive invasion of his cancer with multiple recurrences. I don't think this is common. Please try not to let your mind get ahead of facts. As I said, a simple haemorrhoid comes to mind first.
Any chance of getting this checked out earlier than the 12 December? Otherwise it's a long time to worry, probably for nothing.
Take care.
