Hypothesis
Can weight loss prevent cancer?
Conclusion
Weight loss could prevent a major portion of common cancers.
Supporting Evidence
- Weight gain is associated with increased risk of several cancers, including postmenopausal breast cancer.
- Obesity increases the risk of colorectal cancer and other cancers.
- Weight loss after menopause is linked to a reduced risk of breast cancer.
Takeaway
If people lose weight and keep it off, they might avoid getting cancer. This is especially true for breast cancer in women after menopause.
Methodology
The study reviews evidence from previous reports and studies published since 2002 regarding the relationship between weight and various cancers.
Limitations
Limited data exist on the effects of weight gain or weight loss on cancer risk, particularly due to the small number of individuals able to achieve sustained weight loss.
