I’m stressing does it sound like I have breast cancer 😭?

I’m stressing and I’m really scared

Last week I was in the shower and I was washing my right armpit and I felt a small lump. I don’t know how long is been there but was considering me is that I have been having nipple piercing for more than 3 years and my right nipple seems like it never fully recovered. At least that what I thought before , because it always gets crusty and it’s always hard and painful to put a new bar ring on without it bleeding or having a white discharge. It goes in and it hurts in the middle ( inside my nipple ) and is seems like is always sore. Now that I know I have a small lump on my right armpit , I can’t stop over thinking that I might have breast cancer because is on the same side. And if I do I don’t know for how long. I been ignoring the nipple thing because I always thought it was still healing and now I regret not getting it checked. I just turn 30 and I don’t have any family members that had breast cancer before.
I called my doctor but they can’t see me until may 1st and until then I know I will be stressing. Is there somewhere else I can be seen before my appointment. The thought of having cancer and not knowing for how long is killing me.
