Cancer is one of those health topics no one ever wants to talk about. For a lot of people, it hits too close to me. But ignoring it won’t make it disappear. The more we know about cancer and cancer prevention, the more prepared we can be. One of the most important things to know is that many cases are preventable and it’s possible to reduce the risk. Whether it’s through lifestyle choices, vaccination, or advancements in early detection, there’s a lot we can do to take control of our health. Here are 7 key l facts about cancer prevention to help you make informed decisions with the guidance of your healthcare provider:
Nearly Half of Cancer Cases Are Preventable
It’s staggering but true: 30-50% of cancer cases are preventable through lifestyle changes and early detection. This means the choices we make—what we eat, how active we are, whether we avoid tobacco or limit alcohol—can significantly reduce our risk. Early detection through screenings like mammograms, colonoscopies, and Pap smears also plays a vital role in catching cancer early, when it’s most treatable. While we can’t control everything, we have more power over our health than we might realize.
The HPV Vaccine Can Prevent Over 90% of HPV-Related Cancers
Human papillomavirus (HPV) is linked to several types of cancer, including cervical, anal, and some head and neck cancers. The good news? The HPV vaccine has the potential to prevent more than 90% of these cases, making it one of the most effective cancer prevention tools available. This vaccine isn’t just for kids, so catch-up vaccinations are recommended for many adults as well.
Exercise Protects Against Multiple Cancers
We know exercise is good for us, but did you know it can reduce the risk of eight different types of cancer? Regular physical activity helps regulate hormones, reduce inflammation, and maintain a healthy weight, all of which contribute to lowering cancer risk. The recommendation is 150-300 minutes of moderate activity (like brisk walking) or 75-150 minutes of vigorous exercise (like running) each week. This is certainly a great motivation to make the time to work out.
Alcohol Plays a Bigger Role Than You Might Think
Alcohol doesn’t just damage the liver; it’s responsible for 6% of all cancers and 4% of cancer-related deaths. Even modest drinking can increase your risk of cancers like breast, liver, and throat. The safest approach? Reduce or eliminate alcohol consumption altogether. If giving up alcohol feels like a big step, start by setting limits like no drinking on weekdays or sticking to one drink on social occasions. Small changes can have a meaningful impact over time.
Early Diagnosis Saves Lives
Cancer is far easier to treat when caught early, which is why early diagnosis programs are so important. These programs aim to raise awareness of early warning signs, like unusual lumps, persistent pain, or unexplained weight loss, while also making screenings more accessible. For example, lung cancer screenings for long-term smokers or colonoscopies starting at age 45 can drastically improve survival rates by detecting cancer at earlier stages. If something feels off, don’t wait. Early action could make all the difference.
Genetics Play a Role, But It’s Smaller Than You Think
There’s a common misconception that cancer is mostly hereditary, but only 5-10% of cancer cases are linked to genetic factors. That said, understanding your family history is crucial for identifying potential risks. If you have a family history of cancers like breast, ovarian, or colorectal cancer, talk to your doctor about genetic testing or increased screening options. Knowing your risks allows you to be proactive with prevention and early detection strategies.
Breakthroughs in Early Detection Are on the Horizon
One of the most exciting developments in cancer prevention is the emergence of multi-cancer early detection (MCED) tests. These cutting-edge tests use a single blood sample to screen for multiple types of cancer simultaneously. While they’re still in development, MCED tests have the potential to revolutionize how we detect cancer, catching it earlier than ever before—even before symptoms appear. Though not widely available yet, this technology is a sign of hope for the future of cancer prevention and proof that the conversation around cancer is not only about loss.
