I have attached some of the highest quality links. Put your cursor over it and click on it to get directed there.
You can get to this information by going to the american cancer society website at
www.cancer.org and at national cancer institute at
www.cancer.gov each of these sites allow you to search by "type of cancer" and they have colon and rectal cancer together in the selection, but they separate the information later.
On the NCI website once you select colon and rectal cancer, click on Treatment. Keep on clicking on "next section" at the bottom and you will eventually get to where it talks about radiation.
The american cancer society (ACS) has a link to the NCCN website so you can get there from it or you can go directly to
www.nccn.org and select "treatment guidelines"
If you prefer to go via the ACS website to get there, click on "choose a cancer topic", select "colon and rectal", and select "treatment and decision tool" and it will direct you the the NCCN guidelines (along the left hand margin). From the NCCN website, choose "rectal cancer" since they have it addressed separately. It is addressed separately like this because they are treated differently (ie, radiation).
It may be a bit overwhelming with all the "medical-ease" but it has protocols used by surgeons and oncologists.
Also, if you are going to Cleveland Clinic, type in cleveland clinic colorectal in your web-browser (google, MSN, whatever you have) and you will get a link there.
I hope this helps. I have not included each and every "click" or even ALL of the information that you can find on these sites. But believe me, I have been very deep into all these sites - clicking on every single topic I can find when it comes to rectal cancer.
Let me know if you have any other questions or need additional help to find something specific on these sites.
