Summary
Overweight and obesity are linked to an increased risk of eight specific cancers, including stomach, liver, and thyroid. This adds to the five other malignancies previously associated with excess body weight.
Area of Science:
- Epidemiology
- Oncology
- Public Health
Background:
- Excess body weight is a growing global health concern.
- Previous research has identified several cancer types linked to obesity.
Purpose of the Study:
- To analyze the association between overweight/obesity and cancer risk.
- To update the list of malignancies linked to excess body weight.
Main Methods:
- Meta-analysis of over 1,000 epidemiologic studies.
Main Results:
- Overweight and obesity increase the risk of eight cancers: stomach, liver, gallbladder, pancreas, ovary, thyroid, multiple myeloma, and meningioma.
- This finding expands upon the five cancers (breast, endometrial, etc.) previously linked to excess body weight.
Conclusions:
- Excess body weight is a significant risk factor for a wide range of cancers.
- Public health strategies should address obesity to reduce cancer incidence.

The Body Mass Index (BMI) is a numerical value derived from a person's weight and height, used to categorize individuals into weight ranges. It is calculated using the formula: weight in kilograms divided by height in meters squared. Obesity is a health condition characterized by excessive accumulation of adipose tissue that poses health risks, often diagnosed with a BMI ≥ 30. This excess fat storage occurs when surplus dietary calories are converted into triglycerides and stored in...

Several factors can increase the risk of cancer in an individual. About 50% of cancer cases can be prevented by adopting a healthy lifestyle, regular exercise, eating healthy, and following a modest cancer prevention diet. Epidemiological studies have consistently shown that populations with vegetable and fruit-rich diets have reduced the incidence of cancer. On the other hand, populations who have a diet rich in animal fat, red meat, junk food, or high calories are predisposed to cancer.

Chronic stress has been linked to both the onset and progression of serious health conditions, including Type 2 diabetes and cancer. Type 2 diabetes, a widespread chronic illness, is closely associated with obesity and insulin resistance, both of which often worsen under stress. Studies indicate that men experiencing high levels of chronic stress face a 45% higher risk of developing diabetes compared to those with minimal stress. Stress triggers physiological responses that elevate blood...

Stress often leads to unhealthy habits like smoking, excessive drinking, and overeating, which offer short-term relief but ultimately increase long-term health risks. These behaviors create a cycle that temporarily lowers stress levels but can result in severe long-term health consequences. Breaking these habits is essential to reduce the risk of chronic diseases and improve overall well-being. Three primary changes that support better health include quitting smoking, reducing alcohol intake,...

Cancers arise due to mutations in genes involved in the regulation of cell division, which leads to unrestricted cell proliferation. Modern science and medicine have made great strides in the understanding and treatment of cancer, including eradicating cancer in some patients. However, there is still no cure for cancer. This is largely due to the fact that cancer is a large group of many diseases.
