A recent study reveals a troubling increase in 11 types of cancer among younger individuals in England, with lifestyle choices—particularly the rising obesity rates—likely playing a significant role. Although cancer cases in this demographic remain relatively rare, the findings underscore the potential long-term health implications of everyday habits.
Considering these findings, Dr. Donald Grant, a general practitioner and senior clinical adviser at The Independent Pharmacy, highlights key lifestyle behaviors that could elevate cancer risk, empowering people to make more informed health decisions.
Dr. Grant explains, “The recent surge in cancer cases among younger populations serves as a stark reminder of how our daily routines can impact our future health. While genetics are a factor in cancer development, lifestyle decisions significantly influence overall risk. Let’s delve into the habits that might be increasing your cancer risk.”
Being overweight or obese
Dr. Grant notes, “One of the most substantial lifestyle-related risks is ineffective weight management, with mounting evidence linking obesity to various cancers, such as bowel, breast, and pancreatic cancer. An excess of body fat can adversely affect hormone levels, including insulin and estrogen, potentially fostering cancer development over time. Achieving a healthy weight through a balanced diet and regular physical activity is crucial for reducing overall risk.”
Physical inactivity
He continues, “A lack of physical activity can further exacerbate cancer risk by contributing to weight gain. Exercise is vital for hormone regulation, inflammation reduction, and immune support. Even moderate activities, like daily walking, can have a significant impact over time. Data from the Department of Health and Social Care indicates that over 22% of adults are physically inactive, emphasizing the prevalence of this risk factor.”
Excessive alcohol consumption
Dr. Grant also points out, “Excessive alcohol consumption can severely affect our health and increase the risk of cancers such as liver, breast, and mouth cancer. Alcohol can damage cells and hinder the body’s ability to repair itself effectively. Reducing alcohol consumption or abstaining altogether is among the most effective strategies for lowering this risk and promoting long-term health.”
Smoking
Dr Grant said: “Like alcohol, smoking is one of the worst habits we can engage in when it comes to long-term health. It is a leading cause of cancer, particularly lung cancer, but is also linked to cancers of the mouth, throat and bladder. Data reveals that while smoking is on a downward trend, over 10% of adults in the UK still smoke, meaning it remains a significant public health concern. Quitting smoking is one of the best things people can do to reduce cancer risk and maintain a healthy lifestyle.”
Consuming processed foods
Dr Grant said: “What we eat has a massive impact on our day-to-day well-being. A diet high in processed foods, red meats and low in fibre can negatively impact long-term health and has been linked to certain cancers, particularly bowel cancer. Diets lacking in fruit, vegetables and whole grains may also deprive the body of essential nutrients and antioxidants that help protect against cell damage.”
Prolonged sun exposure
Dr Grant said: “Spending extended amounts of time in direct sunlight without substantial protection from harmful UV rays can increase the risk of skin cancer. Ultraviolet (UV) radiation can damage skin cells, particularly during peak hours or when sunburn occurs. Using sunscreen, wearing protective clothing and limiting sun exposure can help reduce this risk. A lot of people don’t realise that UV rays can penetrate through clouds and even glass, making protection essential all year round.”
Inadequate sleep and persistent stress
Dr Grant said: “It’s often overlooked, but poor sleep and chronic stress can indirectly contribute to cancer risk by affecting hormone balance, immune function and lifestyle behaviours. Over time, this can make it harder for the body to repair damage and maintain overall health. Aiming for seven to nine hours of uninterrupted rest each night and managing stress are important for long-term wellbeing.
“Overall, as cancer continues to rise among young people, it’s vital that Brits understand the harmful lifestyle habits that can further increase their risk. By adopting a well-balanced diet, avoiding bad habits such as smoking or excessive drinking, anyone can improve their long-term health.”
Dr Grant qualified as a doctor in Bristol in 1985. He has wide clinical experience as a GP in and around the city.
