Hi @gulzar. Welcome to Connect! We're glad you've joined our community. Unfortunately, i'm not about to provide medical advice or a diagnosis through this site, but here is some information from Mayo Clinic about blood in urine: http://www.mayoclinic.org/diseases-conditions/blood-in-urine/basics/definition/con-20032338?_ga=1.186151337.1839142009.1464703877. I noticed one of the possible causes is side effects from medications, particularly anti-cancer drugs. Are you taking anything for the neuroendocrine gastrimona that could be causing this?

I'm also tagging @tropicallady1276 and @cindywho01 who have posted about this topic in the past and may be able to provide some additional insight.

Please keep us updated and let us know how the biopsies turnout!
