Childhood obesity is a growing concern in many countries around the world, with an estimated 40-50 million children aged under 5 currently overweight or obese.

This is a worrying trend, as obesity in childhood is associated with a range of health problems, including an increased risk of developing cancer.

What is Childhood Obesity?

Childhood obesity is defined as having excess body weight for a child’s age, height, and sex.

One way to measure obesity in children is by measuring their body mass index (BMI), which is calculated by dividing their weight in kilograms by their height in meters squared.

According to the World Health Organization, a child is considered overweight if their BMI is at or above the 85th percentile and is considered obese if their BMI is at or above the 95th percentile for their age and sex.

What are the Health Risks of Childhood Obesity?

Obesity in childhood is associated with a range of health problems, including:.

Type 2 diabetes
Heart disease
High blood pressure
Asthma
Sleep apnea
Joint problems

In addition to these health problems, childhood obesity is also associated with an increased risk of developing cancer.

How Does Childhood Obesity Increase the Risk of Cancer?

There are several ways in which childhood obesity can increase the risk of developing cancer:.

1. Inflammation

Obesity has been linked to chronic inflammation in the body, which can increase the risk of cancer. Inflammation is the body’s response to injury or infection, and chronic inflammation can damage cells and increase the risk of cancer.

2. Insulin Resistance

Obesity can also lead to insulin resistance, which occurs when the body’s cells become resistant to the effects of insulin, a hormone that helps regulate blood sugar levels.

Insulin resistance is associated with an increased risk of several types of cancer, including breast, colon, and pancreatic cancer.

3. Hormone Imbalances

Obesity can also lead to imbalances in hormones such as estrogen, which can increase the risk of breast and ovarian cancer.

Which Types of Cancer are Linked to Childhood Obesity?

Childhood obesity is associated with an increased risk of several types of cancer, including:.

Breast cancer
Colon cancer
Pancreatic cancer
Liver cancer
Lung cancer
Kidney cancer
Thyroid cancer
