Adopting healthier lifestyle habits could significantly reduce the risk of developing cancer, according to health experts. Oncologists highlight that daily habits such as smoking, poor dietary choices, inactivity, alcohol consumption, inadequate sleep, and prolonged periods of sitting can all play a crucial role in an individual’s long-term cancer risk. Tobacco use, in particular, remains the foremost preventable cause of cancer globally, with strong links not only to lung cancer but also to cancers affecting the mouth, throat, bladder, kidney, pancreas, and oesophagus. Even non-smokers are at risk, as passive smoking can increase their chances of developing lung cancer. Quitting smoking can have immediate health benefits, with notable reductions in cancer risk becoming evident within just a few years.
Obesity is also closely associated with an increased risk of several types of cancer, including those of the breast, colon, kidney, endometrial, and oesophagus. The presence of excess body fat can lead to inflammation and hormonal changes that create an environment conducive to tumour development. Engaging in regular physical activity is encouraged, with health professionals recommending at least 150 minutes of moderate exercise per week, such as brisk walking, cycling, or light workouts. Such physical activity can help mitigate inflammation, regulate hormone levels, and support overall metabolic well-being.
Prolonged sitting is another factor that doctors caution against, as spending extensive hours seated each day may raise the risk of colorectal and endometrial cancers, even among those who maintain regular exercise routines. Diet is equally important in cancer prevention, with experts advising the limitation of processed meats like sausages, bacon, and deli meats, which are linked to a higher risk of colorectal cancer. A high intake of red meat could also elevate the risk of bowel cancer. Moderation in alcohol consumption is crucial, as even moderate drinking can increase the likelihood of breast, liver, and colorectal cancers.
Conversely, a diet abundant in fibre, vegetables, fruits, healthy fats, and whole foods may contribute to lowering cancer risk. Cruciferous vegetables such as broccoli, kale, and cabbage are particularly beneficial, as they contain compounds that can bolster the body’s natural defence mechanisms. Lesser-known risk factors are also emphasized by doctors, including excessive sun exposure and the use of tanning beds, poor sleep and sleep cycle disruptions, long-term night-shift work, and exposure to harmful environmental substances like radon gas.
Healthcare professionals stress that preventing cancer does not necessitate drastic lifestyle overhauls overnight. Instead, they advocate for small, consistent improvements, such as quitting smoking, reducing intake of processed foods and alcohol, maintaining physical activity, protecting skin from excessive sun exposure, and ensuring adequate sleep. These gradual changes can substantially decrease one’s long-term cancer risk. Additionally, regular health screenings and medical check-ups are vital components of early detection and prevention, further enhancing the chances of tackling cancer effectively.
