Matted vs Well-Defined Tumors - Difference on Prognosis?

[julierene]

Have any noticed a pattern about the tumor differentiation? My Onc said I had 2 "well-defined" tumors in my liver about 2cm and 1cm. I noticed some people said they had matted tumors in their liver and did very well on treatment. I was wondering if well-defined tumors carried a prognosis that was different? for better or worse, I'm just interested to hear if there is a difference. Thanks!
