rectal exam is also known as the DRE and
is one of the diagnostic tests used for prostate cancer.
During the test, a doctor will use a latex rubber as
well as a lubricant and use a finger to manually examine
the prostate gland. The peripheral zone of the prostate
gland is directly next to rectum, so any irregularities
can be detected by a doctor. A healthy prostate gland
feels smooth, soft, and symmetrical. Any hardness, jaggedness,
or lumpiness could be indications of prostate cancer.
