Cancer is one of the leading causes of death worldwide, and while some risk factors, like genetics, are out of our control, many lifestyle choices play a big role in increasing or decreasing your chances of developing the disease.
Scientists have studied how habits such as smoking, unhealthy eating, and lack of physical activity can contribute to cancer, and the evidence is clear: making better choices can lower your risk.
Smoking is one of the most dangerous habits linked to cancer. Tobacco contains harmful chemicals that damage DNA in cells, making it easier for cancer to develop.
According to the American Cancer Society, smoking is responsible for nearly 30% of all cancer deaths, including lung, throat, mouth, and bladder cancers. Even exposure to secondhand smoke increases cancer risk.
The good news is that quitting smoking, even later in life, significantly reduces this risk. Research published in JAMA Oncology shows that people who stop smoking at any age improve their health and reduce their chances of developing cancer over time.
Unhealthy diets are another major factor. Consuming too much processed meat, red meat, sugary foods, or highly processed snacks can increase cancer risk.
Studies have linked diets high in processed meat to colorectal cancer, partly because these meats often contain preservatives like nitrates, which can turn into cancer-causing chemicals in the body.
A review published in The Lancet Oncology classified processed meat as a Group 1 carcinogen, the same category as tobacco.
On the other hand, eating more fruits, vegetables, and whole grains can help protect your body because they are rich in antioxidants and fiber, which fight inflammation and support healthy digestion.
Alcohol consumption is another habit that increases cancer risk. Drinking too much alcohol has been linked to cancers of the liver, breast, esophagus, and colon. Alcohol can damage cells and increase estrogen levels, which may explain its link to breast cancer.
A study in The British Medical Journal found that people who consume more than one drink per day have a higher chance of developing cancer, particularly if they also smoke. Cutting back on alcohol or avoiding it altogether can help lower these risks.
A sedentary lifestyle, or not getting enough exercise, can also raise cancer risk. Being physically inactive is associated with obesity, which is a risk factor for several cancers, including breast, colon, and endometrial cancer.
Excess body fat can produce hormones and inflammation that promote cancer growth. The World Cancer Research Fund recommends at least 150 minutes of moderate exercise, like brisk walking or cycling, each week to reduce your cancer risk.
Excessive sun exposure is another risky habit. UV radiation from the sun damages the skin, leading to skin cancer, including melanoma, which is the deadliest form.
Research from the Skin Cancer Foundation shows that just five sunburns in your lifetime can double your risk of melanoma. Protecting your skin with sunscreen, wearing protective clothing, and avoiding tanning beds can greatly reduce this risk.
Lastly, chronic stress and poor sleep habits may also play a role. While stress itself doesn’t directly cause cancer, it can lead to behaviors like overeating, smoking, or drinking, which increase risk.
Poor sleep has been linked to disruptions in immune function and hormonal changes that may contribute to cancer over time. Prioritizing rest and finding healthy ways to cope with stress can support overall health.
In summary, certain lifestyle habits, like smoking, unhealthy eating, excessive drinking, inactivity, and unprotected sun exposure, can increase your risk of cancer.
The good news is that you have the power to change these habits.
Eating a balanced diet, exercising regularly, avoiding tobacco and excessive alcohol, and protecting your skin can all help reduce your cancer risk. Small changes in your daily routine can add up to big health benefits over time.
