Colonoscopy: A Way to Prevent and Discover Colon Cancer

When it comes to cancer, everyone is afraid, because the outcome of advanced cancer is usually desperate.

Because of the horror of cancer, there are always legends of “anti-cancer vegetables” and “anti-cancer folk remedies” among the people. However, Dr. Clove should remind all friends not to believe these legends. Being cheated of money may also endanger their health.

The following is a brief introduction to reliable methods to prevent colorectal cancer.

Colorectal cancer is more likely to occur after 50 years old.

Studies at home and abroad have said that with the increase of age, the incidence of colorectal cancer (including colon cancer and rectal cancer) gradually increases, and significantly increases after 40 ~ 50 years old.

Moreover, the onset age has a certain relationship with the onset position of colorectal cancer. With the increase of age, the onset position gradually moves to the right. The prognosis of right colon cancer is much worse than that of left colon and rectal cancer.

One of the Key Measures to Prevent Colorectal Cancer: Early Detection

The occurrence of colorectal cancer is related to age, genetic factors, eating habits and other factors.

Eat more foods with high dietary fiber, exercise more, maintain good defecation habits, drink less and eat less processed meat products. These good lifestyles are indeed helpful for the prevention of colorectal cancer.

However, genetic factors such as age cannot be changed: with the increase of age, the risk of colorectal cancer will still increase even if one pays great attention to lifestyle. People whose relatives have suffered from colorectal cancer are more likely to suffer from colorectal cancer than others, even if they pay great attention to their lifestyle.

In other words, a healthy lifestyle is helpful to prevent colorectal cancer, but it is not enough. There is also a key way to prevent colorectal cancer-to detect it at an early stage.

If it can be found early, the effect of early colorectal cancer treatment is very good, and the 5-year survival rate is 90%, which is quite different from the 20% survival rate of advanced colorectal cancer.

Do a good job in colorectal cancer screening, early detection of it

Colorectal cancer screening is a series of physical examination items, the most important of which is [colonoscopy] examination. And the age at which [colonoscopy] examination is started and how often it is done vary according to the situation.

If you meet any of the following high-risk groups, it is generally recommended to have a colonoscopy as soon as possible:

    Age 50 ~ 75 years old with first-degree relatives ( Parents, siblings, Children) suffering from colorectal cancer with intestinal symptoms ( Hematochezia, abdominal pain, changes in stool habits, etc.) have precancerous lesions (colorectal adenoma), have previously suffered from intestinal cancer, have familial adenomatous polyposis, have ulcerative colitis, Crohn’s disease, have received pelvic radiotherapy, have received ureterosigmoid colon anastomosis, have obesity, smoking, diabetes, immune deficiency, etc.

For these friends, if no abnormality is found in the first colonoscopy, it is recommended to examine the colonoscopy every 3-5 years, and further treatment if there is any abnormality.

For friends who do not have the above situation, the suggestions are as follows:

    Generally over 50 years old, can do a stool occult blood experiment every year, do colonoscopy every 10 years, because epidemiological studies have found that it takes about 10 years to develop from adenoma to cancer. If the stool occult blood test is positive and the cause cannot be found, colonoscopy can be done in advance.

In short, the screening for preventing colorectal cancer varies from person to person. It is suggested that middle-aged and elderly friends consult oncologists face to face and formulate a set of appropriate screening programs after understanding the physical condition in detail.
