About 3 days ago, I had such a bump under my arm. It hurts a lot when I touch it. At first I thought it was just a Hungarian, so I tried to squeeze it, but it didn't work and it hurt a lot. So I left it at that, but since then it has hurt to the touch. I'm afraid it could be cancer. Is there another option? When I was younger, it happened to me once, but it was smaller and it hurt less, the doctor gave me some ointment and it passed. I don't know exactly what he said it was anymore, but it was okay. I'm 16 years old. Please reply soon, I'm very scared
