Do I have Colon Cancer?

I have been having thin stools on and off. Sometimes my stools will look yellow but sometimes a bit brown. Different shades of brown if you will. I never felt any obstruction but yes, sometimes I had to struggle to get them out. It usually spurts out together... the stools are thinner than usual. sometimes too thin especially when I push too hard and thin pieces come out. Sometimes the stools have normal size. I feel the stools become thinner when I get conscious about it. I have no other major symptoms. I pass stools at least once a day. So i can't say I have constipation. I do not usually get bloated feeling. No abdomen pain. Never saw blood. but did see some brown texture on yellow stools once.. but does this mean bleeding? I suspect it isnt. So my firm conviction is that I do not have any bleeding. I went & saw a GP he said I am alright. It could be some amoebic infection. but I wasnt convinced. i went to a Gastro and he suggested I couldnt possibly be having any cancer but he could recommend a colonoscopy to be sure. I am a worrier, so I have been tensed since then. The doc said my chance of having colon cancer is like .0001% since I am only 27 with no family history. still i am worried. Since I am worried my stools still look all thin. I feel since I am anxious and puts a lot of pressure on my stools size and color.. it may remain the same.

As of now, I am on a medication. Doc said try this for 2 weeks and then decide if I need a colonoscopy or not. I just need some comforting words. that I do not have colon cancer. I don't feel anything. I dont feel I am sick except when I see my stools.
i have no unexplainable fatigue
i am only putting on weight
i hardly have diahrrea
constipation almost no since i go at least once everyday

Please help.

hey, ive actually been having the same issue as you like pale or yellow stool this been happening to me ever since i began working out and switched my diet. i have done blood work, ultrasound, and am about to see a GI for an endos, so far everything is good, am a hypocondriac an always think the worst too.i think you would have alot of other issues if it was cancer.
