Haha. that is why you are going to be a dr and I am not Melindy  Oh school...ahhhh...yay neuroticness? Haha. Just studied colorectal cancer. Fun stuff...you know it takes min. 10 yrs to develop colo-rectal cancer--5 yrs for adenoma development and 5 years for it to turn into cancer...it seems like we should be a lot better at detecting adenomas/carcinomas...you know given that there is a 10 year window...screening anyone? melindy - does the good old fashion finger test do any good at all or should you just line up for colonoscopies? Well...since you asked Bill--and these are Canadian guidelines...I assume American are the same DRE is necessary--we've been told "if you don't stick your finger in it, you will stick your foot in it"...but that said...it will only detect the presence of blood or masses/irregularities to about 7cm (the rectum is 15cm )...so if a patient comes in presenting with abdominal cramping, bleeding, etc...well guess what. Second step is fecal occult blood--but people don't like doing this...it involves smearing your own poo on a card with a stick and seeing if there is a colour change. 3rd step--barium enema, sigmoidoscopy, colonoscopy. It really depends on availability and risk assessment for what you get. If you have family hx of colorectal with a relative who was diagnosed before 50 yrs or 2 first degree relatives with it then you should have colonoscopy at 40yrs or 10 yrs before the relatives cancer diagnosis whichever is earliest. If you have family hx above 50 years or 1 first degree relative then colonoscopy at 40 years... Normal screening guidelines for average risk with no family history is at 50 years... |
