Dywedodd y Gweinidog bod gwell prawf sgrinio ar gyfer canser y coluddyn hefyd ar fin cael ei gyflwyno. Mae'r prawf presennol – sy'n profi am waed cudd yn yr ysgarthion (gFOBt) – weithiai’n cael ei weld fel un anodd ac amhleserus. Y rheswm am hynny yw bod angen casglu dau sampl o ysgarthion ar dri diwrnod gwahanol.
The Minister said an improved test for bowel cancer screening is also set to be introduced. People can sometimes find the current test – known as guiac faecal occult blood test (gFOBt) – difficult and off-putting. This is because it involves collecting two stool samples on three separate days.
