The main aim of colonoscopy is to identify and confiscate cancerous or precancerous lacerations. During this process, a scope is used by the doctor to examine the internal structure of the large intestine. Many people undergo cancer screening in their 50's. This procedure must be performed by an experienced doctor and the entire process lasts for about 30 to 60 minutes. Before examining your intestine medications will be given to you to make you feel relaxed and drowsy. You will be asked to lie on the table on your left side and then the doctor will insert a tubular instrument known as a colonoscope for examining any abnormality in the inner lining of the colon.

The instrument is inserted through the rectum and advances towards the large intestine. Colonoscopy specialist in Fresno is equipped with specific training, experience and professional credentials. You may feel mild cramps during the entire procedure which is pretty normal and you can keep taking deep breaths to reduce the cramping. The instrument will be slowly withdrawn once the doctor is done with the procedure and your bowel will be carefully examined. If during the process the doctor can sense any abnormality then a small amount of tissue will be removed from the inner lining of the intestine which is known as a biopsy.

You are required to reveal before the doctor any special medical conditions you have like pregnancy, allergies from any medicine, or any complicated heart or lung condition.
