Warts are so common as to have become a metaphor for any blemish. I have had several warts in childhood, most likely because my immunity was immature along with the rest of me. They went away, as do most warts. I have had a few warts on and off since, since the HPV that produces them is so widespread.
My immune reaction took care of them, For some reason, I now have a wart between my toes that bears watching. Hopefully it will go away like the rest. Warts rarely become malignant, They can cause problems with breathing if they block the airway, such as the larynx (voice box) or bronchi (breathing tubes). I had such a case in my Allergy/respiratory disease practice that sounded like asthma to the referring Doctor.
Elderly people can develop a variety of skin bumps, that my grandmother called “moles”. In the past month, I have developed a reddish bump on my nose. It looks a lot like the “intradermal nevus” pictured in an accompanying article from “consultant360”. Seborrheic Keratoses are common, and I have some of those too. Of course,
I have a regular crop of scaly “actinic Keratoses” for my Dermatologist to freeze with liquid Nitrogen during my twice yearly visits to prevent them from developing into cancer. I have a suspicion that many home remedies for warts, and the scraping and freezing efforts of dermatologists merely stir up the infected cells in the lesion and incite the immune system to mop up.
Time will usually do the job, but they are often annoying and there is always the temptation to treat them.
