Why Warts Form Under the Armpit and How to Prevent Them

Warts under the armpit can appear for various reasons, most commonly due to a viral skin infection such as HPV (human papillomavirus). This virus can spread easily through direct skin contact or by sharing personal items. Other contributing factors include constant skin friction, excessive sweating, and poor hygiene, which create a warm and moist environment where the virus thrives. A weakened immune system can also increase the risk of developing them.
Tip: Avoid removing them yourself—visit a doctor for safe and effective treatment.
