The Link Between Excess Body Weight and Cancer Risk
A lot of people know that being overweight or obese can cause health problems like diabetes and heart disease. But not as many people know that being overweight can also make you more likely to get cancer. Research indicates that overweight or obesity may be associated with approximately 10% of new cancer cases annually in the United States. This means that how much you weigh is very important for your long-term health.
Too much body fat changes how the body works. It can change hormone levels, cause inflammation that lasts for a long time, and change how cells grow and divide. These changes can make it more likely that cancer will develop over time. People can make healthier choices that may lower their risk of cancer if they understand this link.
How being overweight can cause cancer
Fat tissue in the body is more than just a place to store extra calories. It is really active and makes hormones and chemicals. When a person is overweight or obese, their body often makes more of certain hormones, like insulin and estrogen. These hormones can make cells grow faster than they normally would when they are too high. Cancer can happen when cells grow too quickly or in a way that isn’t controlled.
Another problem that comes with being overweight is chronic inflammation. Carrying too much fat, especially around the belly, can cause a low-level inflammatory response that lasts all the time. Over time, this inflammation can hurt healthy cells and make it more likely that some of those cells will become cancerous.
Being overweight has been linked to a number of different kinds of cancer. These include breast cancer (especially after menopause), colon cancer, kidney cancer, liver cancer, pancreatic cancer, and uterine cancer. Studies continue to show that the risk goes up as body weight goes up.
Habits that make you gain weight can also make you more likely to get cancer. Eating a lot of processed foods, sugary drinks, and high-calorie meals, for instance, can make you fat. Not getting enough exercise is also a big problem. If you keep doing these things for a long time, they can change how your body works and make you more likely to get sick.
Easy Ways to Lower the Risk
The good news is that making small changes to your daily life can greatly lower your risk of getting cancer. One of the most important things you can do is to keep a healthy weight. This doesn’t mean that everyone has to be very thin. The goal is to stay at a healthy weight for your height and body type, not to lose weight.
Regular exercise helps the body burn calories and keep hormones in check. Walking, biking, dancing, or swimming are all fun ways to keep your weight in check. Most days of the week, experts say you should get at least 30 minutes of moderate exercise.
Eating well is also important. Eating a variety of foods, such as fruits, vegetables, whole grains, beans, nuts, and lean proteins, is good for your health. These foods have vitamins, minerals, and antioxidants that help keep cells safe from damage. Limiting processed foods, sugary snacks, and too much red meat can also help you keep your weight in check.
Regular health checkups are another helpful step. Early screening for cancers like breast or colon cancer can find problems early on, when they are easier to treat.
Body weight is only one thing that can affect your risk of getting cancer. Genetics, the environment, and how you live all have an effect. But staying at a healthy weight, staying active, and eating healthy foods can lower your risk of getting many diseases, including some kinds of cancer. Making even small changes today can help you stay healthy in the future.
