Cancer?

Yep, I’m scared 🤷‍♀️ Everyone says it’s a boil. You can see a head, but obviously I’m worried that because it’s on my breast, I think the worst. I’m on day 4 of antibiotics. Doesn’t hurt or itch. It only hurt when I first noticed it because I tried to pop it, and it swelled very bad 🤦‍♀️ It looked a lot worse a few days ago, and I am noticing it getting better.
