Mae canser y colon, a elwir hefyd yn ganser colorectal, yn un o'r mathau mwyaf cyffredin o ganser ledled y byd.
Yn ôl y World Cancer Research Fund International, canser colorectal yw'r trydydd canser mwyaf cyffredin mewn dynion a'r ail canser mwyaf cyffredin mewn menywod.
Yn 2020, amcangyfrifir bod 1.9 miliwn o achosion newydd o ganser colorectal wedi'u diagnosis yn fyd-eang.
Mae'r achosion o ganser colon yn amrywio yn ôl rhanbarth, gyda chyfraddau uwch mewn gwledydd datblygedig fel yr Unol Daleithiau, Ewrop, ac Awstralia, a chyfraddau is mewn gwledydd sy'n datblygu.
Mae'r risg o ddatblygu canser colon yn yr Unol Daleithiau tua 1 mewn 23 ar gyfer dynion ac 1 mewn 25 ar gyfer menywod.
Fodd bynnag, mae'r achosion cyffredinol o ganser colon wedi bod yn gostwng yn ystod y blynyddoedd diwethaf, yn ôl pob tebyg oherwydd mwy o sgrinio a darganfod cynnar.

How common is colon cancer?
Colon cancer, also known as colorectal cancer, is one of the most common types of cancer worldwide.
According to the World Cancer Research Fund International, colorectal cancer is the third most common cancer in men and the second most common cancer in women.
In 2020, there were an estimated 1.9 million new cases of colorectal cancer diagnosed globally.
The incidence of colon cancer varies by region, with higher rates in developed countries such as the United States, Europe, and Australia, and lower rates in developing countries.
The lifetime risk of developing colon cancer in the United States is about 1 in 23 for men and 1 in 25 for women.
However, the overall incidence of colon cancer has been declining in recent years, likely due to increased screening and early detection.
