Hi, Ashley
As a follow up to my earlier reply, if an individual has symptoms attributable to the colon such as a change in bowel habits or blood in stools or long term tummy pain, then a colonoscopy is warranted irregardless of the age of the individual.
Alternatively, if an individual wishes to have a colonoscopy to check/screen his colon, then he or she can certainly opt to do one irregardless of their age
