Drinking a lot of whole milk might raise your risk of dying from cancer, and the more you drink, the higher the risk — especially if you drink a lot.

Assessment Explanation
The claim uses 'association,' which is correct for observational studies that cannot prove causation. It accurately describes both linear and non-linear relationships, which can be detected via statistical modeling (e.g., spline regression) in cohort studies. The phrasing avoids implying causation, which is appropriate given the lack of experimental control. No overstatement is present.
More Accurate Statement
“Consumption of high-fat milk is associated with a linear and non-linear increase in cancer mortality risk, suggesting that risk rises steadily with intake and may accelerate at higher levels.”

High vs. low-fat dairy and milk differently affects the risk of all-cause, CVD, and cancer death: A systematic review and dose-response meta-analysis of prospective cohort studies
This study found that people who drink more high-fat milk have a higher chance of dying from cancer, and the more they drink, the higher the risk — especially at very high levels. This matches exactly what the claim says.
