It is possible to palpate a mass 6 cm inside the anus in physiologic and pathologic situations.
Generally, in the anterior wall of the rectum 4-5 centimeters from the anal verge, men can palpate the prostate outside the rectal wall, and women can palpate the cervix, and due to individual differences, the possibility of palpating the prostate or cervix at 6 cm inside the anus cannot be ruled out.
In pathological cases, a mass palpated at 6 cm inside the anus may be rectal cancer, polyps, internal hemorrhoids, etc. Rectal cancer 6 centimeters inside the anus is called median rectal cancer and may be felt by rectal palpation as a hard knot, ulcer, or mass. This test should be considered if there is a change in bowel habit, blood in the stool, etc.
