A type of cancer more commonly diagnosed in North America, particularly in black men, and related to factors such as genetics and diet.

Digital Rectal Exam (DRE)

A physical examination technique used to palpate the prostate for abnormalities.

PSA

Prostate-Specific Antigen, a blood test involved in the screening for prostate cancer.

Colonoscopy

A diagnostic procedure that allows visual examination of the colon and rectum.

Hemorrhoids

Swollen veins in the rectal area that can cause discomfort and bleeding.

Fissure

A tear in the lining of the anal canal that can cause pain and bleeding.

Anorectal Fistula

An abnormal connection between the rectum and the skin, typically resulting from infection.

Regular testing procedures aimed at detecting colorectal cancer or precancerous conditions.

Involuntary Control

Control that occurs without conscious effort, as seen in the internal sphincter of the anal canal.

Somatic Sensory Nerves

Nerves that transmit sensory information from the skin to the brain, allowing for sharp pain perception in the anal area.

Mucus in Stool

Presence of mucus which can indicate gastrointestinal issues.

Fecal Occult Blood Test (FOBT)

A screening test for blood in the stool that can indicate colorectal cancer or other gastrointestinal diseases.

Family History

Medical history from one's relatives that may indicate a genetic risk for diseases like cancer.

Symptoms of BPH

Common signs include urinary frequency, urgency, and difficulty with urine flow.

Prostate characteristics

Includes size, shape, surface, consistency, and sensitivity; important in prostate assessments.

Skeletal Muscles

Voluntary muscles surrounding the anus that assist in bowel movements.

A surgical procedure used to treat urinary symptoms due to an enlarged prostate.

Stool Test Results

Outcomes of tests examining stool for blood, pathogens, or abnormal characteristics.

PSA Screening Recommendations

Guidelines for when to begin prostate specific antigen testing based on risk factors.

Abdomen Examination

Physical assessment of the abdominal area, part of a broader digital rectal examination.

Clinical Guidelines

Recommendations established for medical practice based on research evidence.

Stool Consistency

Refers to the texture of stool, which can provide insights into gastrointestinal health.

Change in Bowel Habits
