I'm A 35 Year Old Female. I Have Soft Swelling

I'm a 35 year old female. I have soft swelling in the left supraclavicular area. I also have a lump in my left armpit that is slightly tender when I try to feel it. My bloodwork came back as really good. I am scheduled for a CT scan in 3 weeks. I'm really worried about this being cancer. I think the CT scan and maybe even a biopsy should be done much sooner than 3 weeks away so that I can begin treatment as soon as possible if it is cancer. What is your opinion?
