What Do My Lab Test Reports Indicate?

Hi , It all started with diarrhea and bloody stool: went and consulted my doctor 8 months ago. She sent me to GI... They did endo and colonoscopy....... They ended up finding a carcinoid tumor in rectum. 8 months later I still have watery bloody or green diarrhea, It sometimes look very greasy or like oil floating. They did so many stool test and found nothing. I have pain at times in lower back and stomach. Also my stomach look way bigger than it did before all this started. I am scared and they have no answers just test after test and I dont feel as if they testing for the right thing. I bleed as if I have my period out my ASS at least 3-5 times a week. The blood is bright red to maroon, drips on floor when go to clean self. They told me I don t have hemorrhoids and now looking into bacterial growth again for second time. My last MRI they found a growth coming from my rib that they going to recheck in 6 months.. I am so confused and dont know if I should move on from these doctors or wait it out?
