Hello i have have had some anal bleeding on and off for the last 4 months. it seems to happen after straining to have a bowel movement. blood is bright red and is seen on the paper after wiping and some stain on the stool. could this be cancer? 44 m?

Your description sounds more like hemorrhoids being the underlying cause. However, you should definitely schedule an appointment with your primary doctor so that a proper examination and testing can be done.

Common things are common, rare things are rare. Bright red blood per rectum usually comes from a crack/fissure in the anal skin triggered by a hard/bulky or rapidly delivered stool. Colon cancer bleeding originates higher up in the digestive tract, taking on a darker red or purple color after gut enzymes act on the blood. Please discuss this with your doc.
