Hormonal
Obesity in breast cancer patients is mediated by hormonal profiles that stimulate breast cancer growth, including higher estrogen, androgen, and insulin/IGF-1 levels.
Weight loss helps reduce breast cancer risk by lowering levels of growth-stimulating hormones like estrogen and insulin. This biological mechanism supports the clinical recommendation for weight management.
GoodSupportsHIGH confidence
Obesity also is associated with hormonal profiles likely to stimulate breast cancer growth.
Why this rating
Based on multiple prospective studies and cohort analyses linking hormone levels to cancer risk.

- Initial treatment for type 2 diabetes should be a combination of metformin and either an SGLT-2 inhibitor or a GLP-1 receptor agonist to achieve cardiorenal protection, rather than monotherapy or older agents like sulfonylureas.Strong
- For patients with specific monogenic obesity syndromes (leptin deficiency, POMC/PCSK1/LEPR mutations), targeted pharmacotherapy (recombinant leptin or setmelanotide) is highly effective and should be prioritized, unlike in polygenic obesity.Strong
- Continued weekly administration of 2.4 mg subcutaneous semaglutide prevents weight regain and promotes further weight loss in adults with overweight or obesity, whereas switching to placebo results in significant weight regain.Strong
