According to Cancer Research UK, around 44,100 people develop colorectal cancer each year, making it the fourth most common cancer in the UK.
Recognising the signs of colorectal cancer early on is crucial for effective treatment. This is especially true for those under the age of 45 who don’t have access to regular colorectal cancer screening. There has been a rise in cases of early onset colorectal cancer in recent years, making it imperative for younger patients to understand the symptoms.
Read on to discover the red flags for colorectal cancer everyone should be aware of.
Blood in stools
Blood in the stools, or haematochezia, is one of the most common signs of colorectal cancer. A recent review of 81 studies, revealed that blood in stools, alongside abdominal pain, is the most prevalent symptom of this disease. In fact, blood in stools was the leading symptom in 45% of cases.
The study analysed 24.9 million Early Onset Colorectal Cancer cases, making it one of the largest studies of its kind.
While finding blood in your stool can be alarming, it’s important to note that it can also be a symptom of less serious issues, such as haemorrhoids or anal fissures. However, consistent or recurrent blood in your stools should never be ignored. It’s therefore essential to see a doctor if you notice this symptom.
Abdominal pain
Abdominal pain is another leading symptom of colorectal cancer. The same recent study found that 40% of patients experienced abdominal pain as an early symptom. This pain can vary in intensity and may be persistent or intermittent.
Colorectal cancer-related abdominal pain often results from the tumour causing a blockage or narrowing in the intestines. This can lead to cramping, bloating, and discomfort. It’s important to pay attention to any persistent abdominal pain, especially if it’s accompanied by other symptoms such as changes in bowel habits or blood in the stool.
Unexplained fatigue
Unexplained fatigue can be a subtle yet significant symptom of colorectal cancer. Cancer cells can cause fatigue by consuming a lot of your body’s energy and by releasing substances that affect normal cell functions. Chronic blood loss from the tumour, even if not always visible in the stool, can also lead to anaemia, which contributes to feelings of tiredness and weakness.
If you find yourself feeling persistently tired despite getting adequate rest, it’s important to discuss this with your doctor. Fatigue, when unexplained and persistent, warrants a thorough investigation to rule out colorectal cancer and other potential causes.
Unexplained weight loss
Unexplained weight loss is another early symptom of colorectal cancer. Cancer can affect the body’s metabolism and cause changes that lead to weight loss, even without changes in diet or exercise habits. The presence of a tumour can also cause a loss of appetite or make you feel full quickly, leading to a reduction in food intake.
Weight loss that occurs without a clear reason should always be taken seriously. If you are losing weight without trying, especially if it is accompanied by other symptoms like abdominal pain or changes in bowel habits, it is essential to seek medical advice.
Being aware of the red flags for colorectal cancer is crucial for early detection and effective treatment. If you are experiencing any of these symptoms, or you are concerned about your colorectal cancer risk, schedule an appointment with Mr Michael Stellakis.
