Overweight and obesity have become a growing problem in the US, with an alarming 70 percent of adults and 30 percent of children and adolescents classified as overweight or obese.

In addition to the well-known health risks of weight gain such as heart disease, diabetes, and high blood pressure, being overweight can also increase the risk of cancer.

The Link between Overweight and Cancer

According to the American Cancer Society, being overweight or obese increases the risk of several types of cancer, including:.

Breast cancer in postmenopausal women
Colorectal cancer
Endometrial cancer
Kidney cancer
Pancreatic cancer

The reason for this link is not entirely understood, but researchers believe it has to do with the excess fat tissue in the body. Adipose tissue, or fat tissue, produces hormones and growth factors that can promote the growth of cancer cells.

Fat tissue also increases insulin resistance and inflammation, which can contribute to cancer development.

Overweight Teens at Risk

The risk of cancer doesn’t just start in adulthood – overweight teens are also at increased risk.

A recent study published in The Lancet Diabetes & Endocrinology found that overweight teenagers have a higher risk of developing colon cancer and rectal cancer in adulthood.

The study followed over 240,000 men in Sweden for an average of 35 years and found that those who were overweight at age 16 had a 2.08-fold increased risk of colon cancer and a 2.38-fold increased risk of rectal cancer compared to those with normal weight at age 16. The study also found that each 10 kg increase in body weight at age 20 was associated with a 32 percent increased risk of colon cancer and a 17 percent increased risk of rectal cancer.

Other Health Risks for Overweight Teens

The risk of cancer is not the only concern for overweight teens. Obesity can also lead to the development of numerous health problems that can affect quality of life and increase the risk of early death.

Some of the most common health risks for overweight or obese teens include:.

Type 2 diabetes
High blood pressure
Heart disease
Stroke
Joint problems
Fatty liver disease
Sleep apnea
Asthma
Mental health issues such as depression and anxiety

Preventing Weight Gain in Teens

Preventing weight gain in teens is crucial for reducing the risk of cancer as well as other health problems. Here are some ways to promote a healthy weight for teens:.

Eat a healthy and balanced diet with plenty of fruits, vegetables, whole grains, and lean protein

Conclusion

Overweight and obesity are serious health problems that can lead to a wide range of health issues, including an increased risk of cancer.

Overweight teens are particularly at risk for developing cancer and other health problems, making prevention and treatment of weight gain crucial for a healthy future. By promoting a healthy lifestyle with a balanced diet and regular physical activity, parents and caregivers can help reduce the risk of cancer and other health problems for children and adolescents alike.
