In recent years, the prevalence of colorectal cancer across the world has been increasing dramatically1 every year, and patients who are diagnosed early only account for a small proportion of patients. Clinically, the early diagnosis rate of colorectal cancer is low, mainly because people are generally not aware of, or do not pay enough attention to the early signs of the disease.
Early signs of colon cancer
Irregular bowel movements One of the signs of colon cancer is a persistent change in one’s bowel habits, such as constipation, diarrhoea, or a change in stool consistency. While there is no set rule on a “correct” frequency of defecation, sources have stated that anything regular between three times a day or three times a week is average. Blood in Stool Blood in the stool can be a sign that is easily overlooked. This can apply for individuals who suffer from haemorrhoids, where rectal bleeding is painless. It is therefore important for you to check your faeces regularly for blood. If the colour of your faeces is dark and red, or accompanied by pus, do seek medical assistance. This can happen as early as the first stage of cancer, so do seek help as soon as you can. Weight loss or fatigue If you are a healthy person who suddenly develops symptoms such as body weight loss, jaundice, body weakness or listlessness, you may want to look into these issues. This is because colon cancer can increase the pressure of the entire abdominal cavity, resulting in intestinal obstruction, jaundice and other symptoms. Bladder Incontinence For many people, frequent urination can be overlooked as a health issue, especially amongst older people. However, urinary dysfunction can also be early symptoms of colon cancer. Patients may also experience burning sensations when urinating.
