It’s not strange to be afraid of colonoscopy test for colon cancer screening as one needs a lot of requiring activities such as taking special diet, fasting, taking a laxative or using an enema to empty your colon before the examination.
Nevertheless, having a colonoscopy is necessary for detecting colon and rectum abnormalities especially tumor or malignant tissue inside the colon. Moreover, tragic fact from Thailand National Cancer Center stated that the number of colon and rectum cancer patients is constantly rising from 10,624 patients in 2011 to 12,563 patients in 2014, leading Thailand as the 5th of the world’s most colorectal cancer population.
It is predictable that if there is no policy enforcement on colon cancer screening, the number of a cancer patient will be doubled in 10 years and the mentioned disease will cause more than 3,000 deaths per year.
DR. NATCHADOL KITTIWARARAT, the oncologist said that there are two significant factors causing colon cancer; uncontrollable and controllable factors.
- Age: at 45 years old, a person can develop a possibility of having a colon cancer
- Having a tumor or polyp in an intestine
- Having a cancer in other parts of the intestine
- Having a medical history with Inflammatory Bowel Disease or IBD
- A family history of tumor or intestine cancer
- Unhealthy daily diet; grilled or processed foods such as bacon, sausage, dried meat or meatballs
- Overweight or obesity
- Less exercise or sedentary lifestyle
- Frequent alcohol consumption
Colon Cancer Screening
According to American Cancer Society recommendation, people at average risk of colorectal cancer that has no personal history related to inflammatory bowel disease (IBD) or certain types of polyps and no family history with colon cancer can start a regular screening at age 45.
The colonoscopy procedure can detect polyps and harvest the malignant sample to be studied by a special laboratory test and it can also remove certain cancerous polyps out before it develops to cancer.
The complexity of colonoscopy might be the main factor why people avoid undergoing a colon cancer screening. It is because there may be some food or water restrictions and laxatives to be taken to empty the colon. Though the colonoscopy is highly safe, it can cause some complications such as flatulence or having gas and there can be a bleeding condition in case of tumor removal.
Blood Test for Colon Cancer
Medical technology has reached another step forward, and now we can screen a colon cancer by blood test which reduces all complex process and unpleasant feeling before and during the colonoscopy.
The blood test for colon cancer screening can be performed immediately. The patient does not have to go through food and water restriction. The blood test is conducted in a specialized laboratory where cancerous cells contaminating the blood cell can be detected, and the result will be finalized in approximately 2 weeks.
Colon Cancer Blood Test Ensures Accurate Result
The blood test for colon cancer screening is well accepted nationwide. Research shows that this procedure has 95% accuracy compared to colonoscopy procedure.
The state-of-the-art technology is undoubtedly noticeable and is still improving. However, ignoring colon cancer screening is the primary factor causing an increased number of the patients with the said disease. Most of the patients seek medical help only when the symptoms already show or in the late stage which complicates the treatment and chances to cure cancer.
So, it is highly suggested that people age over 45 years old are generally fall in a risky group and should have a colon cancer screening. Detecting the early stage of cancer can promote early treatment as well and emphasize colon cancer cure.
