Colorectal cancer screenings look for malignancies of the colon and rectal lining. Colonoscopies are one of the most effective screening procedures because they can both detect and remove colorectal polyps.
A colorectal polyp is a tiny cluster of cells that grows on the colon’s or rectum’s lining. Pre-cancerous polyps are quite common.
If polyps are found during a colonoscopy, they will be removed during the process, preventing them from developing into cancer. Colorectal cancer screening can often detect cancer early, when it has not spread and is easier to treat.
When colorectal cancer is discovered at an early stage before it has progressed, the five-year relative survival rate is approximately 90%; however, only about four out of every ten colorectal cancers are discovered at this early stage. Survival rates are poorer when cancer has progressed outside of the colon or rectum, says the colorectal cancer doctor in Kolkata.
Regular colonoscopies allow cancer to be detected when it is small and treatable.
The extent to which cancer has spread determines the treatment. If colon cancer has not gone beyond the lining of the colon, it is the easiest to treat and usually only requires surgery to remove polyps or cut out the afflicted section of the colon.
If colon cancer has progressed beyond the colon, the treatment will be more severe. It may include colon or other tissue removals, chemotherapy, radiation, and immunotherapy. If cancer has spread or advanced too far, treatment to improve quality of life and reduce cancer symptoms may be advised rather than remission, says the specialist of colorectal cancer surgery in Kolkata.
If you are putting off getting screened, and have colon cancer, cancer will grow and spread to other organs. When cancer spreads from the colon to surrounding structures the five-year survival rate drops to 71% and when cancer spreads to distant organs such as the liver or lungs the survival rate drops to 41%.
Screenings for colonoscopy can detect more than only cancer and polyps. They assist doctors in detecting irregularities, damage, blockages, and other potential problems.
If you have one or more risk factors, if you’re at average risk and it’s been 10 years since your last colonoscopy, or if you’re experiencing symptoms of colorectal cancer, schedule a colonoscopy screening today, says the colorectal cancer surgeon in Kolkata.
