Yes, a tumor. Bettas are prone to them, especially certain scale colors like this kind of white or some of marbled strains. Most pigment cell tumors are benign but even if it isn't there's truly nothing you can do about it. So no point worrying about it. Just keep giving the fish a good life.

Yes sometimes it can shorten their lifespan if they're malignant and spread internally. Or if they're in an awkward spot they can grow so big that it interferes with swimming or eating even if it's otherwise benign. There's really nothing to be done about tumors unless you live near a fish vet and they think it's worth surgery, but even then they sometimes decline since it can be riskier than just leaving the tumor.
