Colonoscopy biopsy from descending colon revealed. hyperplastic polyp. is this a concerning find?

No. Entirely benign and nothing to worry about.

If this was the only finding, it is not a cause for concern. For healthy diet: http://www.choosemyplate.gov/., exercise 30 minutes/day, drink enough water daily so your urine is mostly colorless, have safe sex, no tobacco alcohol weed or street drugs. Get HPV vaccine. Wish you good health! Safe sex: https://www.hopkinsmedicine.org/health/wellness-and-prevention/safer-sex-guidelines

Hyperplastic polyps are very common and are of no concern. They do not increase the risk of colon cancer. Continue a high fiber diet and follow the recommendations of your primary care doctor for future colon cancer screening. Good luck.
