Question) I keep getting moles on my neck. Why is that?

Recently, I've started seeing a few small, wart-like bumps around my neck. At first, they were small, so I didn't pay attention, but now they're growing so much that I can feel them, and I'm starting to worry. It's not painful, but because it's on my neck, it often gets caught on clothes and necklaces, and it's also a bit unsightly. I sweat a lot and have a lot of friction, and I think I've had some recent weight fluctuations. I'm curious if these skin tags are simply due to aging or friction, or if they're also related to hormones or health. If you've had similar experiences, please share your advice or experiences. When did they start to appear? Did you have them removed at a hospital? Do they go away naturally?
