Colorectal most cancers is the fourth most prevalent cancer in Korea. In accordance to the ‘National Cancer Registration Stats 2019’ not too long ago introduced by the Ministry of Health and Welfare and the National Most cancers Centre, colorectal cancer accounted for 29,030 cases (11.4%) out of 254,718 cancer conditions , coming in fourth following thyroid most cancers, lung cancer, and abdomen most cancers
As colorectal most cancers has amplified considerably owing to the western diet and enhance in the obese population, the dying fee has also increased. The colorectal cancer dying price in 2019 was 17.5 for every 100,000. In comparison to 2009 (14.3 per 100,000), it improved by 22.1% in 10 a long time, surpassing stomach most cancers to 3rd area in phrases of cancer fatalities.
Numerous people today fret about colorectal cancer when they see blood mixed in the stool. On the other hand, blood in stools can also be prompted by hemorrhoids, so it is significant to see a colorectal specialist.
◇ Colorectal most cancers bleeding is darkish red, hemorrhoids are bright pink bloody stools
If bloody stools seem, colorectal most cancers should really be suspected. Bleeding from colorectal cancer is easy to confuse for the reason that the symptoms are related to those of hemorrhoids. However, the colour of blood in stool brought on by colorectal cancer is distinct from the color of blood in stool brought on by hemorrhoids.
Hemorrhoids predominantly demonstrate brilliant purple bleeding, while colorectal cancer demonstrates different shades relying on the site of the cancer and the sum of bleeding. Bleeding from the higher section of the substantial intestine is black or dark purple blood combined with the stool. Bleeding from a tumor shut to the rectum, which is the suggestion of the significant intestine, benefits in darker pink blood. Even so, it is not quick to establish colorectal cancer by the coloration of the stool by itself, so it is significant to request health-related notice.
Jeong Seong-min, professor of surgical procedures at Ilsan Paik Clinic of Inje University, explained, “It is challenging to obviously distinguish no matter whether it is colorectal most cancers or hemorrhoids just by the color of the stool.
◇ Adenoma, which degenerates into colorectal cancer 5 to 10 a long time later
Colorectal most cancers is brought on by a variety of factors these kinds of as genetics and the atmosphere. Among them, a ‘colon polyp’, which is a protrusion on the floor of the interior mucous membrane of the colon, is a key hazard factor for colorectal most cancers. For this motive, colon polyps are recognised as the ‘seeds of colon cancer’.
In normal, it is advised to have a colonoscopy each and every 5 yrs. If you have a spouse and children heritage of colorectal most cancers or a heritage of colon polyps, you should really be screened each and every 2 or 3 years. Polyps are uncovered in 30-40% of colonoscopy examinations for all those aged 50 or in excess of.
Polyps are divided into neoplastic polyps, which can come to be cancerous, and non-neoplastic, which are not associated with cancer. Most neoplastic polyps are ‘adenoma’, a precursor to colorectal cancer. Most adenomas degenerate into colorectal most cancers after 5 to 10 a long time, so they will have to be taken out by colonoscopy.
The more substantial the adenoma, the increased the chance of establishing cancer. Adenomas fewer than 1 cm in diameter have significantly less than a 2.5% likelihood of most cancers. Less than 10% of adenomas of 1 or 2 cm are described, and 20-40% of adenomas bigger than 2 cm are noted. If the dimension of the adenoma is additional than 2 cm, the likelihood of getting cancerous is pretty significant, so it have to be taken out.
Massive adenomatous polyps can also develop into cancerous, so they need to be taken out. According to exploration, eliminating polyps discovered throughout colonoscopy can lessen colorectal most cancers by 70-90% and mortality by 50%.
If a polyp has been removed all through a colonoscopy, you should really have one more colonoscopy to check the standing of your colon. Professor Cha Jae-myung of the Section of Gastroenterology at Kyunghee University Medical center in Gangdong stated, “If you have removed a person or two little polyps fewer than 1 cm in dimensions with a colonoscopy, you ought to have a abide by-up colonoscopy after 5 .many years.”
Professor Cha Jae-myung stated, “If 3 or additional adenomas have been taken out, if the sizing of the adenoma is 1 cm or much more, or if the large-hazard adenoma has been excised, an further colonoscopy ought to be executed on after 3 yrs. “
In addition, if the problem of the huge intestine is lousy or if it has not been cut correctly, it can be tested yet again following a year. Thus, it is necessary to talk to a gastroenterologist on how normally to have a colonoscopy.
If you are taking medicines that can cause bleeding, such as antiplatelet medicines, you must focus on with your gastroenterologist whether the drug need to be stopped just before the polyp removing course of action. Also, if you develop a fever, significant abdominal agony, or bloody stools soon after a polyp resection, you should go to the hospital promptly for remedy.
◇ Much more actual physical activity decreases the chance of colorectal most cancers by 27%
Standard physical exercise is vital to avert colon cancer. A meta-investigation of scientific studies discovered that individuals who were being bodily lively had a 27% reduced threat of colorectal most cancers than people who had been not.
Some research have shown that an ample intake of vitamin D can assistance stop colorectal most cancers that happens just before the age of 50. This is the result of a study carried out by Professor Kimmy Eng’s group at the Dana-Farber Cancer Institute in the United States on 94,205 nurses amongst the ages of 25 and 42 (the American Gastroenterology Journal ‘Gastroenterology’). All those who consumed 300 IU or more of vitamin D every single working day had a 50% reduced danger of colorectal cancer in advance of the age of 50.
Try to eat foods wealthy in vitamin D. It is uncovered in oily fish (salmon, tuna, mackerel), liver, egg yolks, and cheese. You can also eat cereals, milk, or vitamin D dietary supplements with additional vitamin D.
To reduce colon polyps and colorectal most cancers, △ Lessen the percentage of body fat in calorie intake to 30% or considerably less, △ Ingest 20-30g of dietary fiber for every working day, △ Steer clear of purple or processed meat processing, △Drink plenty of fermented milk products and solutions, and △1.5L for every working day Consume a lot more drinking water, steer clear of speedy food items, advantage foods, seasoning, and smoked foodstuff as considerably as attainable, work out often, sustain an suitable body weight, steer clear of ingesting and smoking cigarettes, and getting a colonoscopy each and every 5 many years right after age 50.
