The importance of recognising the early warning signs and symptoms of bowel cancer

June marks Bowel Cancer Awareness Month and although the month-long campaign strives to raise awareness regarding the fourth most commonly diagnosed cancer in Australia, it also offers a stark reminder of the importance of early intervention and regular testing.

According to the Cancer Council, each year, about 15,300 Australians are diagnosed with bowel cancer with the average age at diagnosis being 69 years old.

Bowel cancer typically develops in the inner lining of the bowel and usually begins with growths called polyps, which may become cancerous if left undetected. While the risk of developing bowel cancer increases significantly with age, if detected in its early stages it has a greater chance of being treated successfully.

As part of Bowel Cancer Awareness Month, Starts at 60 sat down with the experts to offer an in-depth look at what symptoms to be on the lookout for, the risk factors associated with bowel cancer and what steps to take to prevent bowel cancer developing.

What to look out for: Signs and symptoms

The most common symptoms of bowel cancer include a change in bowel habits such as diarrhea and constipation. Other warning signs to be on the lookout for are blood in the stool, abdominal pain, unexplained weight loss, anal or rectal pain, fatigue, as well as bloating or cramping.

Although these are some of the symptoms often associated with bowel cancer, it’s important to note that many people with bowel cancer experience no symptoms in the early stages of the disease.

Medical expert Dr Vivek Eranki, who has worked in emergency departments and across a broad range of medical fields, highlighted the importance of regular medical checks given symptoms can go unnoticed and may not even appear until the later stages of the disease.

“Often the symptoms are not noticeable in the early stages which is why it is important to undertake regular screening. Many people undertake colonoscopies every few years to ensure polyps are removed.  The importance of full blood tests every year is essential for overall good health. This helps to identify potential health issues and also assist with the management of your health,” Eranki said.

The importance of regular medical checks is crucial to ensure the early detection of bowel cancer and greater treatment outcomes. The National Bowel Cancer Screening Program aims to do just that by reducing illness and death from bowel cancer by helping detect the early signs of the disease using a free, simple test that can be done at home.

The factors that could put you at risk of developing bowel cancer

There are a number of risk factors that contribute to your chances of developing bowel cancer. Age seems to be the most prominent, with the disease more common in people over the age of 50.

Other factors that may play a role in the development of bowel cancer include family history, a history of developing polyps, high red meat or processed meat consumption, being overweight or obese and high alcohol consumption.

Although there is a myriad of factors that can increase the chance of developing bowel cancer, Dr Nick Musgrave, Anatomical Pathologist and Ambassador for Pathology Awareness Australia points out that “we do see an increased risk with age, which is why the screening program targets those aged 50 plus”.

“Around 90 per cent of cases are diagnosed in people aged 50 plus,” he said.

Prevention is key: How to reduce your risk

As the old adage goes, prevention is better than cure, and when it comes to preventing bowel cancer there are a number of dietary and lifestyle changes people can make to give themsleves the best chance of avoiding the disease.

Eranki states that “prevention is key” and offers a number of simple ways to reduce your risk which include reducing your consumption of red meat, stopping smoking, moving more and keeping active, drinking plenty of water, reducing alcohol intake, and undertaking regular health checks.

According to the World Cancer Research Fund (WCRF) Third Expert Report 2018, between 30 to 50 per cent of cancer can be prevented with a healthy lifestyle, and when combined with regular screening this number increases.

Musgrave backed up these claims, stating “all types of cancer are most treatable when detected early” and further stressed the importance of the National Bowel Cancer Screening Program.

“Even if you feel well and have a healthy lifestyle it’s important to participate in screening. Unfortunately, not everyone is even aware of the bowel screening program. Currently, participation in the program remains below 45 per cent which is a disappointing result. I would urge people over 50 to participate in screening themselves and also to encourage their family and friends to do so. It might seem like an uncomfortable topic but you could save someone’s life,” he said.

“The reason that this is so important is that a bowel cancer that is diagnosed early has a very good chance of being cured. Unfortunately, cancer that is diagnosed late and that has spread to other organs is only cured in a small percentage of cases. So diagnosing bowel cancer early is critical.”

The National Bowel Cancer Screening Program, to which Musgrave refers, aims to reduce death and illness from bowel cancer by detecting the early signs of the disease.

The free test kit is sent to all Australians between the age of 50 and 74, every 2 years. The simple test can be performed in the comfort of your own home and can be sent directly to the pathologist so they can detect any blood in your stool sample.

The test kit includes clear instructions on how to perform the screening which involves collecting 2 tiny stool samples from 2 separate bowel movements.
