- Sigmoidoscopy—a diagnostic procedure that allows the doctor to examine the lower one-third of the large intestine.
- Colonoscopy—a diagnostic procedure that allows the physician to examine the entire length of the large intestine.
What causes HNPCC?
HNPCC is caused by an inherited mutation or abnormality in a gene that normally repairs our body’s DNA. There are at least five of these genes known as mismatch repair genes that are known to be associated with HNPCC. If genetic damage is not repaired, cancer can occur.
