I got the results back.  I have a rare form of recurring, non-cancerous, but
almost cancerous tumors called aggressive fibromatosis (desmoid tumors).
I'm waiting to hear back from my surgeon to get a recommendation to an
oncologist.  I guess the best way to handle these tumors is through surgery
(which I've already had done) and radiation.

It's such a rare condition that not many people know how to handle/treat it.

The thing is with these tumors, is that they keep growing back.  I've been
on a cancer newsgroup and got some news from an actual doctor.  This is the
message:

Hi kili.
It's a fairly rare condition, and I've only seen it a few times.
It's best considered a very low-grade sarcoma, as it sits right on the
dividing line between benign fibromas and malignant fibrosarcomas.
The mainstay of treatment is surgery. If complete resection is possible that
is often curative. If only partial resection is possible, radiotherapy may
prevent progression or recurrence. Chemotherapy is of no use at all.
Metastasis does not happen, but local recurrence and progression is common,
and this can be life threatening.

This is quite a good starting site

Please note however, it says there that sometimes chemotherapy is used. As
far as I'm aware, however, only surgery and radiotherapy have been found to
be effective. Tamoxifen has also been shown to sometimes produce responses.

Good luck
