Study Reveals Bowel Cancer On The Rise Among Young Adults: Expert Shares Prevention Tips

Bowel cancer, also known as colorectal cancer, is a type of cancer that begins in the colon or rectum, parts of the large intestine. It often develops from abnormal growths called polyps, which can become cancerous over time if untreated. According to a new study published in The Lancet, bowel cancer cases have risen significantly among younger adults aged 25-49. While bowel cancer has long been considered a condition affecting older individuals, the research indicates otherwise among younger age groups.

The study highlights a steady rise in cases among those aged 25-49, and although older adults remain more likely to develop bowel cancer overall, the higher-than-expected incidence in younger adults is worrying. The shift is particularly noticeable in high-income countries, where lifestyle factors like poor diet, sedentary habits, and obesity are believed to play a significant role.

Why Are Bowel Cancer Rates Increasing In Young People?

In an interaction with the editorial team of Onlymyhealth, Dr Ganesh Shenoy K, Department of Surgical Gastroenterology, Robotic, Minimal Access, General and Bariatric Surgery,  Kauvery Hospitals, Electronic City - Bangalore, points to a combination of factors contributing to this alarming trend:

• Diet and processed foods
• Sedentary lifestyles
• Obesity
• Gut health and the microbiome
• Genetics and family history

Warning Signs Of Bowel Cancer To Watch For

Detecting bowel cancer early significantly improves outcomes. While the condition is often asymptomatic in its early stages, younger adults should be vigilant for the following warning signs. Here are a few Dr Shenoy's lists: 

• Persistent changes in bowel habits (e.g., diarrhoea, constipation, or narrower stools)
• Blood in the stool or rectal bleeding
• Abdominal pain, cramping, or discomfort
• Unexplained weight loss
• Fatigue or weakness

“If any of these symptoms persist for more than a few weeks, seeking medical advice is essential,” Dr Shenoy notes.

Prevention Tips For Younger Adults

Talking about bowel cancer prevention Dr Shenoy explains, “Although some factors like genetics cannot be controlled, adopting healthy lifestyle habits can significantly reduce bowel cancer risk.” Here are key prevention tips:

1. Prioritise a Healthy Diet

Include more fruits, vegetables, whole grains, and fibre-rich foods. Limit red and processed meats and reduce the consumption of ultra-processed foods and sugary drinks.

2. Stay Physically Active

Regular physical activity not only reduces cancer risk but also improves overall health. Aim for at least 30 minutes of moderate exercise most days of the week.

3. Maintain a Healthy Weight

Obesity increases cancer risk, so adopting balanced eating habits and regular exercise is crucial.

4. Limit Alcohol and Avoid Smoking

A study published in the Journal of Cancer Prevention suggests that both smoking and excessive alcohol consumption are linked to a higher risk of bowel cancer. Avoid smoking altogether and moderate alcohol intake.

5. Be Aware of Family History

If bowel cancer runs in your family, discuss early screening options with your healthcare provider. Colonoscopies and stool-based tests can help detect abnormalities early.

6. Prioritise Gut Health

Incorporate foods rich in probiotics like yoghurt and fermented foods and prebiotics such as garlic, onions, and oats to support a healthy gut microbiome.

Bottomline

The increasing rates of bowel cancer among young adults highlight the urgent need for awareness, early detection, and lifestyle changes. By recognising the warning signs, prioritising preventive measures, and ensuring timely screenings, one can address this rising health challenge and reduce the risk of bowel cancer in both younger and other people.
