Okay, I am not a doctor, and it's good that you are going to the doctor to check it out. But I have had the same weird bumps on my skin that if you squeeze it, the waxy white stuff comes out. For me, they are skin abscesses (or boils), and the stuff that is squeezed out is just pus and infected "stuff" that is really gross but not cancerous. Although I don't think you're supposed to squeeze it out because it could make the infection worse...and I have had one abscess that grew so much and became so painful that I had to have it lanced twice. It was very painful, and took a while to heal. So try not to mess with it. :-) And definitely show your doctor, just to make sure that's what it is.
