The Atlantic reports on a new study out of Tel Aviv University which looked at the "relationship between childhood obesity and future diagnoses of urothelial, or bladder, and colorectal cancers" and found that "childhood obesity is associated with a 50% higher risk of urothelial or colorectal cancers."
From the Atlantic:
IMPLICATIONS: While these results only tell us about the incidences of two specific types of cancer, Ari Shamiss, one of the doctors involved in the study, has indicated that he is currently researching connections between childhood obesity and other cancers in the hopes of uncovering other connections. We still need to learn whether obesity is directly causing the high risk of cancer, and, perhaps most essentially, whether losing weight is effective -- and if so, how much and when - in lowering it.
The full study, "Overweight in Adolescence is Related to Increased Risk of Future Urothelial Cancer," is published in the journal Obesity.
