I have liposarcoma and the surgery was October 19, 2011. Radiation finished February 29, 2012. So far with MRIs every three months, there has been no sign of recurrence. My oncologist and I monitor my health regularly and I'm approaching a year cancer-free. I don't know if there is anything that will prevent liposarcoma from coming back but I do know you need to be aware of any changes in your body. Take time every day to meditate and calm your mind. It's worked for me so far. Good luck.
