Hi, this depends on the size of the skin tag. We usually can leave them alone as they are usually not cancerous. For larger ones, we usually remove them under local anaesthesia. We usually inject/apply a numbing agent, then remove it with a minor procedure. This is usually quite straightforward.
Emails are not known to be a very secure form of communication. If you would like to send me sensitive data, I would advise you to save it in a zip or pdf file and lock it with a pin that you would tell me via another means. Alternatively use PGP encryption.
