My boyfriend who is 36 years old age had desmoid tumor in his abdominal area. The doctor recommended regular MRI to monitor the growth of the tissue. His tumor is around 10mm (less then 4 inches?)  The second MRI shows little to no growth, but his doctor still recommended surgery. I am wondering if surgery is the only option or tumor this stage should just be left alone.  p.s. He got surgery done to remove many polyps in his colon several years ago.

Summarized question: Is surgery the only option for desmoid tumor?
