Colon Cancer
Conditions
Colorectal cancer (CRC) originates in the colon and rectum, both parts of the large intestine. It is a common and potentially deadly cancer. About 4 percent of men and women will get colon cancer in their lifetime. What makes it challenging is that it can grow without showing any symptoms for a long time. By the time symptoms appear, it may be very advanced and have spread to other body parts.
- Abdominal discomfort, pain, cramping, or gas
- Blood in stool or abnormal bleeding from the rectum
- Persistent changes in bowel movements lasting more than a week or two
- Weakness/fatigue
- Unexplained weight loss
Remember, these symptoms could also relate to other health issues. Even the slightest sign should prompt a doctor's visit.
- Colonoscopy: A tube with a camera examines the colon, samples suspicious lesions, and removes pre-cancerous polyps for analysis.
- Stool tests: Check for hidden blood or genetic material from polyps/cancer.
- Imaging: Scans like CT can also spot potential issues.
The American Cancer Society suggests colonoscopies every 10 years from age 45, with variations based on risk factors. Your NYGA doctor will guide you on the best screening choice.
The good news is that CRC can often be prevented or detected early. Most CRC starts as polyps, which doctors can remove before they turn into cancer. Treatment options include:
- Surgery
- "Biological" therapy: Smart molecules targeting cancer cells
- Chemotherapy
Although colon cancer is being diagnosed in younger adults, recent advances are improving survival rates. Personalized therapies, combined with surgery and chemotherapy, are making a difference.
Frequently Asked Questions
How long does a colonoscopy take?
The procedure typically takes 20 to 45 minutes, though patients should expect to spend additional time preparing and recovering from sedation.
How much does a colonoscopy cost in NYC, and does insurance cover it?
Many screening colonoscopies are covered by insurance, though coverage varies depending on your plan and whether the procedure is performed for screening or diagnostic purposes. NYGA accepts most major insurance plans and can help verify your benefits before your appointment.
How often do I need a colonoscopy?
For average-risk individuals, screening is often recommended every 10 years beginning at age 45. Patients with certain risk factors or previous findings may require more frequent screenings.
What is the difference between a screening and a diagnostic colonoscopy?
A screening colonoscopy is performed to detect colorectal cancer or polyps before symptoms develop. A diagnostic colonoscopy is performed to evaluate symptoms such as rectal bleeding, abdominal pain, anemia, or changes in bowel habits. Some insurance consider a follow up colonoscopy for prior polyps or cancer as a diagnostic test since something irregular has been found on a prior exam.
Is a colonoscopy safe?
Yes. Colonoscopy is considered a very safe procedure when performed by experienced gastroenterologists. Serious complications are uncommon, and the benefits of early detection and prevention generally far outweigh the risks.
