White lump on nipple

Hey everyone.

Months ago maybe a year, I noticed a small, white lump in my nipple. It was really small so I didn't think anything of it. Around this time, I noticed every now and then that I'd get a bit of crustyness/flakyness on that nipple and that my breast would itch alot. I got a little worried but convinced myself it was just because of my menstrual cycle and ignored it (perhaps stupidly)


As I said, that was quite a good few months ago, but recently, I've noticed that same nipple has recently sort of sunken in the middle. This made me remember the lump, so I checked and it's still there, although it hasn't grown any and is still the same colour.

However, I've now spotted another small, white lump in my other nipple. It's very slightly smaller than the other one, and the same colour.

both lumps are so small that I can't touch them to see if they're painful.

I've examined my breasts but they've always been kind of lumpy so I can't tell if there's any lumps in my breast. As far as I'm able to see for myself, there's only those two little white lumps in my nipples.

I'm 20 years old, never been pregnant and not sexually active and I'm just really really worried. Could it be cancer?
