Tired of lesions popping up.Worried Again.

I had to come here and get off the rest of the Internet because I am once again making myself crazy with worry. Recently went in to an urgent care because I had been having some pain in my knee. I have RA and teach Zumba classes, so I am used to aches and pains, but this knee pain was new. They think meniscus injury, but because of my bc history do x ray. I just hate how everything turns into tons of tests. Anyway, she calls me back and says she doesn't want to worry me but there is a spot on my x ray, on the femur,and they want me to take copy and follow up with my onc. She showed me the x ray, and now I can't get that spot out of my mind. Called my onc and I now have bone scan scheduled for Monday. She said nothing on knee during previous scans and that has me worried. This happened when I had back pain too. Off for tests and they say lesion on spine, but too small to say mets, they watch and it is stable. I also have to have MRI in march for abdomen because something showed up on CT back in Nov. that they are watching. I have read over 40, most new bone lesions are mets. It is small, with sclerotic rim. I wish Monday was here already. I feel like the boy who cried wolf with my family and they all just say, you will be fine. I try to keep my worry in, but it is hard. Anyone else have lesion on their femur? I am 2 1/2 years out of treatment. Can something new show up so fast? I am just soooo tired of MRIs CTs and Scans! I feel fine, but things keep popping up and I just want to scream. Decided to check in here instead. Don't know if this warrants a post, but I needed to type out. Thanks!
