### input:
Hello.  I am female 65.  For decades I have had low abdominal burning in the same place and often think it is a bladder infection but it never is. It often feels like it is moving/twitching and it burns.   I had a bad bout of it recently witn no appetite and lots of anxiety and ended up in the hosptial with constipation.  My md is setting up a colonoscopy and gave me some ativan and celexia. He says the pain and constipation are signs of colon cancer but I have had this recurring burning in the same place for as long as I can remember. He also said I was about as anxious and dry mouthed as a person can be and gave me a shot of valium.   I had been on zoloft for years but was really feeling great, no bowel issues and had gone off zoloft about 10 days before this incident happened and I thought I had sufficiently weaned over several months.  I am still constipated but the anxiety is less and I have a little appetite.  At the hospital they did a digital x-ray and said I was hideously constipated and sent me home with a go-easy and 3 ativan.  That worked well but the symptoms returned, especially the anxiety/butterflies so I started up the zoloft at 50m day but it didnt seem to help and Dr. Wade switched me to celexia yeterday along with an antibiotic for a sinus infection.  All bloodwork is normal.My question is does colon cancer grow in the same place ibs/diverticular is and cause worse distress?  I did get a diagnosis of diverticular years ago but I dont know where it is.  The burning pain is in the same place it always has been for as long as I can remember and the condition has always been non-smell gas and slow moving bowls/constipation but this has been a long spell of it, about a month now from when I stopped taking zoloft, the trip to the ER with anxiety and constipation about 10 days after stopping the zoloft and now 3 weeks back to zoloft but still not eating, moving bowels much and mountains of anxiety.  Then seeing Dr. Wade yesterday.

### output:

Hi there, I completely agree with your doctor who booked you for colonoscopy as vague symptoms like you are describing, better to rule out any cancerous growth inside. Overall I understand you have IBS/ diverticular disease and your concern is that whether cancer can exaggerate the symptoms if it occurs at the same place. This I don't think anyone has concrete evidence about and one can't reply with any certainty. I would not worry too much if colonoscopy comes as normal. Take care, Regards
