Hi everyone

Im wondering if anyone can help, my Nan had a lump on her right hand side,  she recently went to the doctor who sent her for a CT scan and they found something on her bowel, she was supposed to have a procedure today but unfortunately the laxative medicine they gave her just made her vomit for most of the night so she couldn’t have the Colonoscopy. I’m extremely worried that this could be Bowel Cancer. She tends to get extreme pain after eating but we thought maybe she had developed an intolerance to something now I’m wondering if this is connected? Does anyone have any similar experiences? 

Thank you
