Obesity’s Hidden Link to 13 Cancers Revealed by New Research
Obesity is linked to a higher risk of 13 different cancers, according to a leading endocrinologist. New research highlights how excess weight disrupts hormones, damages DNA, and alters gut health—all of which may fuel tumour growth.
Fat tissue produces enzymes that raise estrogen levels in the body. These elevated hormones can accelerate the development of cancers that rely on them, such as breast and prostate cancer.
Obesity also throws off the balance of leptin and resistin, two key hormones. This imbalance can lead to gut dysbiosis, where harmful bacteria thrive, further increasing cancer risk. Additionally, excess weight causes direct damage to cellular DNA, which may trigger the formation of malignant tumours. Dr Marcos Lahera, an endocrinology and nutrition specialist at Madrid’s Hospital Universitario Fundación Jiménez Díaz, stresses the importance of weight management. He notes that maintaining a healthy weight could help prevent multiple cancer types.
The findings underscore a clear connection between obesity and cancer development. By controlling weight, individuals may lower their risk of hormone-driven cancers and reduce DNA damage. Medical experts continue to highlight diet and lifestyle as critical factors in long-term health.
