Is LIPOSARCOMA the same thing as "FATTY TUMORS"? I have had these tumors all my life. When they get so painful I can not stand it anymore I have them removed. The first one was removed at the age of 19 and I was told that they would never turn in to cancer. I am 58 now and am covered in them. Mostly on my arms and legs. Should I be worried?

Thank you so much
