Colorectal Cancer Ranks as the Third Most Common Cancer Among Thai

Colorectal Cancer: A Common Cancer That Should Not Be Overlooked

Colorectal cancer is reported as the third most common cancer among Thai people. Although several factors may contribute to its development, lifestyle and dietary habits are considered important risk factors, particularly diets high in red or processed meat and low in vegetables and dietary fibre.

The disease may develop gradually and may not cause obvious symptoms during its early stages. For this reason, people should understand their personal risk factors, observe changes in their bowel habits, and undergo appropriate health screening.

Who May Be at Higher Risk?

People who may have an increased risk of colorectal cancer include:

๐ People aged 40 years or older

๐ People with a family history of colorectal cancer

๐ People who experience chronic or frequent constipation

๐ People who regularly eat large amounts of meat while consuming few vegetables

๐ People who smoke cigarettes or drink alcohol

Having one or more risk factors does not mean that a person definitely has cancer. However, it may indicate the need for closer health monitoring and consultation with a doctor regarding appropriate screening.

Three Warning Signs of Colorectal Cancer

1. Changes in Bowel Habits

Watch for unusual or persistent changes, such as constipation, diarrhoea, or alternating episodes of constipation and diarrhoea.

2. Rectal Bleeding or Blood in the Stool

Blood may appear bright red or may make the stool look darker than usual. Although bleeding can result from other conditions, such as haemorrhoids, it should still be medically evaluated.

3. Cramping or Persistent Abdominal Pain

Abdominal pain, bloating, or cramping similar to intestinal obstruction may indicate an abnormality in the digestive tract, especially when the symptoms persist or occur with changes in bowel habits.

Other possible warning signs may include unexplained weight loss, fatigue, loss of appetite, or anaemia. However, some people may have no noticeable symptoms in the early stages.

Why Is Early Screening Important?

Colorectal cancer may begin as a small growth or polyp inside the colon. Some polyps can gradually develop into cancer over time. Screening may help doctors detect and remove certain abnormal growths before they become cancerous.

Early detection may also allow treatment to begin before the disease spreads, which can improve treatment options and the chance of recovery.

Screening methods may include:

๐ Stool-based tests

๐ Colonoscopy

๐ Other examinations recommended by a doctor based on age, symptoms, medical history, and individual risk

How to Reduce the Risk

Healthy lifestyle habits may help lower the risk of colorectal cancer:

๐ Eat more vegetables, fruits, whole grains, and fibre-rich foods.

๐ Reduce the intake of red meat and processed meat.

๐ Exercise regularly and maintain an appropriate body weight.

๐ Avoid smoking.

๐ Limit alcohol consumption.

๐ Seek medical advice when bowel habits change or warning symptoms occur.

Do Not Ignore Unusual Symptoms

People who experience persistent changes in bowel habits, blood in the stool, abdominal pain, unexplained weight loss, or unusual fatigue should consult a doctor rather than waiting for the symptoms to disappear.

The earlier colorectal cancer is detected, the earlier appropriate care and treatment can begin.
