I came across an online article about "The risk of Colorectal Cancer" and would like to share some of interesting points here. Cancer has been positioned near the top of the cause of death in Japan. The colorectal cancer is famous that the risk is getting higher over the age of 40. Nowadays, it is said that young people in between their 20s and 30s who develop it increase drastically. In case of the colorectal cancer, there are many cases with no symptoms at an early stage. When it progresses on some level, you have blood in your stool, stomachache and abnormal bowel movement. There are some cases that losing weight and anemia appear. That's why a stool test is very important in medical health check to detect the colorectal cancer early. If you need further investigation in your health check, having a colonoscopy is vital. Especially, having a colonoscopy is highly recommended even though you don't see any symptoms on the horizon when you are over 40. The most worried symptom is blood in the stool, but some people make an assumption that is hemorrhoids and see how it goes. When you are bleeding, it is okay if it is cured. However, you must go see a doctor immediately when you are bleeding many repeatedly. You also should go to a hospital soon if you have stomach ache before bowel movement when you feel bloated and constipation. Actually, the doctor told me to need a detailed examination from the result of my stool test when I had an annual heath check this year. Honestly, I was so scared what if I have a colon cancer. Luckily, from my colonoscopy result, I have no issue with my colon. I just became a grandfather this month and hope to see my grandchild becomes an adult if possible.
