Ive had persistent constipation for over a year now. change in bowel habits, loose and thin stools, mucus in stools, and hemorrhoids. results from not living healthy. my grandpa died of colon cancer in his 50s. im only 26, should i get colonoscopy?

Doctor can examine: Young adults under age 30 are unlikely to have bowel cancer. A person can never tell if he is the rare unlucky one to get cancer at a young age. More importantly, a person cannot live his life worrying about rare diseases. So, the best one can do is live a healthy life, see the doctor for evaluation and do the colonoscopy if advised. That means a visit and full exam by one's primary care doctor.
