Your Weight at Different Ages Could Affect Your Risk of Multiple Cancers

A Swedish study of more than 630,000 adults found that faster or earlier weight gain across adulthood was linked to higher risks of several cancers.

The patterns varied by sex, age at weight gain, and cancer type, with different associations seen in men and women.

Cancers highlighted included liver cancer, esophageal adenocarcinoma, endometrial cancer, renal cell carcinoma, pituitary tumors, and pancreatic cancer.

Because the study is observational and a preprint, it cannot prove that weight gain causes cancer.
