Worried about my husband

Hi there

i am posting full of worry for my husband . He's in the middle of a bowel cancer scare he is very vague with me about it and jokes that he is more concerned that he has a gluten intolerance and can't eat pork pies. So all of a sudden he has been going to the toilet at least 4 times a day he says he doesn't really check them but they're not right ! He's been to see doctor and he's having a telephone consultation on Friday the letter had the words cancer in a lot! don't know what this consultation is???? Also he is having blood test on Thursday .I just want some light shed on the telephone consultation and the only thing I can get out of him about his poop is there is mucas and he may of spotted blood once but he knows I worry... which I am any words of wisdom or advice out there?
