Hello I'm chrissy and very scared

I'm a mother to 3 beautiful girls and 12 years ago I went to my gp with a lump in my leg the gp said it was a cyst and nothing to worry about so I didn't in the past 3 years I've noticed more and more lumps on both thighs and both arms 20 altogether. I went back to my gp and she recommended I go for a scan as she had no idea what they are well that was 4 weeks ago and I've still no appointment. I shouldn't but I have been on Google and I'm now terrified I have some form of cancer and I've left it too long to be treated x
