Dear Dr. i hope this finds you well. I am writing this as a follow up to the previous question i submitted, since the last question i submitted i had a doubt that i could not quite clear and i was hoping you could help me with it. it has been 1.5 years since i had successful wart removal treatment (i waited a year before seeking treatment since wart appear) so 2.5 years in total since it appeared with no recurrence after treatment. in my previous question you mentioned there was no way to be certain but after a year of no recurrance most likely it will not recur and the the problem is gone. So i wanted to clear my doubt, with your knowledge and help, how much time does it have to pass for someone to be certain or practically certain that the problem is gone when this person has received treatment.

Welcome to our Forum.  Thanks for your questions.  I'll be glad to comment.  In preparing to respond I reviewed your earlier interaction with Dr. Handsfield on this topic an agree with all that he said.---

Thank you for your response,  i want like to ask you, based on your knowledge and experience, if electrocautery is one of the best, if not the best treatment for this, why isnt it the norm to use this method in all cases to treat this symptom? also when you typed "if any concerns that your warts were going to concern" the last "concern" did you actually mean "recur"? that part got me a little confused, otherwise everything was clear.

I apologize for the typographical error in my reply.  In the sentence " At this time I would have few, if any concerns that your warts were going to concern.", the last word should have been "recur", not "concern".---

Thank you for the clarification, for my last question i want to mention something that happened with my friend regarding recurrence and how it seems to work. he told me that when he noticed he had a wart he decided to manually cut it with a scalpel, but logically as he didnt do it with a professional, a few weeks later he noticed it grew again, however he also noticed that only the parts he didnt go as deep grew again while the rest didnt. he mentioned it looked "like a crater" lol, he then proceeded to make the same mistake and cut it again, this time he just forgot about it and didnt check closely again until about a year later when he said he saw a small wart a fraction of its original size, he later had it finally removed by a professional. im aware that recurrence in this case was because it wasnt performed by a professional in the first place, but what im trying to ask, by telling you this anecdote, is do recurrences work like this? especially when using destructive methods, in the sense that it only recurs in the areas the virus didnt get removed/destroyed so thats why every time it recurred it only grew in the spots that where not fully removed and thats why it also got increasingly smaller in size with each new recurrence after removal, until it was completely destroyed. i will highly appreciate your insight and expertise. 

As you know, this will be the final response.  When destructive methods of wart treatment, including surgery, electrocautery, or laser therapy occur, if the destructive procedure leaves small amounts of HPV behind this can be a source of recurrence.  Whether or not this happened to your friend I cannot comment but is may be the reason for recurrence.---
