Hi MajesticWhine, sorry you've had to join us, but hopefully this will be a flying visit with you getting good results from your colonoscopy.
(Yes, colorectal cancer is bowel cancer - cancer of the colon or rectum, cancer of small bowel is a different type so that's why they're more specific)
I had colorectal cancer about two and a half years ago now. I was diagnosed after a colonoscopy. They were able to tell me on the day that they had found a tumour and hundreds of polyps (I have FAP which caused the cancer). They took lots of biopsies and I got my diagnosis six days after the colonoscopy. During this time I had blood tests (for cancer markers) and a CT scan to check for spread.
So you will most likely get at least some indication of what's going on on the day of your colonoscopy. Will someone be able to come with you? I was allowed to bring my now ex boyfriend into the consultation. It might be helpful to have a second pair of ears if you are still feeling woozy (are you having sedation?). Also might be handy to take a notebook.
Have your doctors said that cancer is looking likely? As malt says, there are so many possible explanations. I'm so sorry for your loss
and it's completely understandable that your family history is worrying you. Do you have any other symptoms? And have you had any other tests? Even if it is cancer, the treatments are improving all the time and so there's every chance of a good outcome.
I'm sure your GP will be willing to prescribe diazepam and/or sleeping tablets. Lots of posters here have had experience of anxiety, so will hopefully be able to advise.
Have you had a colonoscopy before? I found the bowel prep the worst part. I'd recommend the sedation if you have the option, as some people find colonoscopies uncomfortable. I didn't have any discomfort.
They warn you that there will be some blood if they've done any biopsies, but I was shocked by how much there was (don't know if that's normal or because they did so many biopsies). So be prepared. Unless you're actually gushing bright red blood, or it carries on bleeding for a long time, there's nothing to worry about. You'll also feel a bit gassy thanks to the air they pump in during the procedure. It's all rather undignified really! :)
I don't know if any if that will be helpful. Feel free to ask if you have any questions :)
How old are your children? I don't have any myself, but on the thread there are people with children of every age.
All the best
