Colon Cancer

The colon is the final part of the digestive tract where digestion takes place. It can spread to other body parts in the form of metastases. Most commonly, it occurs in adults, but it can occur in any age group.

cancer often starts as a polyp- non-cancerous growth. However, sometimes they can become cancerous. Therefore if diagnose with polyps, you need to get under regular screening for cancer. Your healthcare providers will perform colonoscopy as a screening tool to know if polyps have become cancerous or not.

Cancer that involves the rectum is known as colorectal cancer.

You must attend all your follow-up visits with the healthcare provider. When you do that, colon cancers can be detected at early stages- when it is more treatable and has not progressed to advanced stages yet.

If you do not attend the follow-up visits and screening tests, polyps may turn cancerous, and you may not know about it.

People who are diagnosed with polyps, those at risk of cancer, or those who are above 50 years should get their screening tests done frequently- once in two years at least. If you have any symptoms of the gastrointestinal tract, you can visit a gastroenterologist in Lahore.
