Mae canser y colon yn cael ei ddiagnosio trwy gyfuniad o brofion a gweithdrefnau, a all gynnwys:
1. Archwiliad corfforol: Bydd meddyg yn cynnal archwiliad corfforol i wirio unrhyw afreolaeth neu arwyddion o salwch.
2. profion gwaed: Gall profion gwaed helpu i benderfynu a oes unrhyw anghysondebau yn y gwaed a allai ddangos presenoldeb canser.
3. Profion stool: Gall prawf stool ddarganfod presenoldeb gwaed yn y stool, a all fod yn arwydd o ganser colon.
4. Colonoscopy: Mae hwn yn weithdrefn lle mae tiwb tenau, hyblyg gyda golau a camera ar y pen yn cael ei roi i mewn i'r rectum i archwilio'r colon.
Yn ystod colonoscopy, gall y meddyg hefyd gymryd samplau meinwe (biopsïau) i'w archwilio ar gyfer celloedd canser.
5. Sigmoidoscopy: Yn debyg i colonoscopy, mae sigmoidoscopy yn archwilio rhan isaf y colon.
6. Colonosgopi rhithwir: Mae hwn yn sgan CT o'r colon sy'n creu delwedd 3D o'r colon a'r rectum.
7. Profion gwaed cudd yn y ffecal: Mae'r prawf hwn yn gwirio am fodolaeth gwaed yn y ffecal, a all ddangos presenoldeb canser.
8. Enema bariwm dwyieithog: Mae hwn yn archwiliad x-ray o'r colon a'r rectum, lle defnyddir deunydd cyferbyniol i amlygu unrhyw anghysondebau.
9. Biopsy: Mae biopsy yn tynnu swm bach o feinwe o'r colon i'w archwilio o dan microsgop i benderfynu a oes celloedd canser yn bresennol.
10. Profion delweddu: Gellir defnyddio sganiadau CT, sganiadau MRI, ac x-ray'r frest i benderfynu a yw'r canser wedi lledaenu i rannau eraill o'r corff.
Unwaith y bydd diagnosis o ganser colon wedi'i wneud, bydd y meddyg yn penderfynu ar gam y ganser, sy'n helpu i benderfynu ar y cwrs triniaeth gorau.
Mae'r stadiad yn seiliedig ar faint a lleoliad y twmer, yn ogystal â p'un a yw wedi lledaenu i rannau eraill o'r corff.

How is colon cancer diagnosed?
Colon cancer is diagnosed through a combination of tests and procedures, which may include:
1. Physical examination: A doctor will perform a physical examination to check for any abnormalities or signs of illness.
2. Blood tests: Blood tests can help determine if there are any abnormalities in the blood that may indicate the presence of cancer.
3. Stool tests: A stool test can detect the presence of blood in the stool, which may be a sign of colon cancer.
4. Colonoscopy: This is a procedure in which a thin, flexible tube with a light and camera on the end is inserted into the rectum to examine the colon.
During a colonoscopy, the doctor can also take tissue samples (biopsies) to be examined for cancer cells.
5. Sigmoidoscopy: Similar to a colonoscopy, a sigmoidoscopy examines the lower part of the colon.
6. Virtual colonoscopy: This is a CT scan of the colon that creates a 3D image of the colon and rectum.
7. Fecal occult blood test: This test checks for the presence of blood in the stool, which may indicate the presence of cancer.
8. Double-contrast barium enema: This is an x-ray examination of the colon and rectum, in which a contrast material is used to highlight any abnormalities.
9. Biopsy: A biopsy is the removal of a small amount of tissue from the colon for examination under a microscope to determine if cancer cells are present.
10. Imaging tests: CT scans, MRI scans, and chest x-rays may be used to determine if the cancer has spread to other parts of the body.
Once a diagnosis of colon cancer is made, the doctor will determine the stage of the cancer, which helps determine the best course of treatment.
Staging is based on the size and location of the tumor, as well as whether it has spread to other parts of the body.
