The Claim
Recent weight loss of 2 kg or more within two years before colorectal cancer diagnosis is associated with a 7.5-fold increased odds of colorectal cancer, indicating that unintentional weight loss in this timeframe is a strong clinical marker of early-stage colorectal cancer rather than a causal factor.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
People who lose 2 kg or more unintentionally within two years before being diagnosed with colorectal cancer are 7.5 times more likely to have the disease, suggesting this weight loss may signal the presence of early-stage cancer.

What the research says
1 studyStudy: Association of Overweight, Obesity, and Recent Weight Loss With Colorectal Cancer Risk
People who suddenly lose 2 kg or more in the two years before being diagnosed with colon cancer are much more likely to have the cancer — the weight loss is a sign the cancer is already there, not what caused it.
