Home Pesticides Tied to Higher Cancer Risk in Kids

Indoor pesticides have been tied to a higher risk of cancer in children, according to a new study in the journal Pediatrics.

Harvard University researchers analyzed 16 studies of children exposed to indoor pesticides. The pesticides include pest control services, flea and tick pet collars, and ant and roach sprays. The analysis compared 7,400 cancer cases with 9,437 healthy children.

Indoor pesticides were linked to a 47 percent increased risk for childhood leukemia and a 43 percent increased risk for childhood lymphomas. Outdoor pesticides, such as weed killers, were linked to 26 percent increased risk of developing brain tumors.

The study authors acknowledge that their research involved analysis of a relatively small number of studies. They also stressed that the pesticides were linked to an increased risk of cancer and were not found to be the cause of cancer.
