Issue Report: Animal testing


Treatment of 100 kinds of cancer costs our nation an estimated $107 billion a year. When cancer strikes, cells multiply uncontrollably, gradually overwhelming the body.

An understanding of how viruses cause tumors and the use of hormone treatments to limit tumor growth were developed using rats, mice, rabbits, chickens, monkeys, and horses. Cancer treatments such as chemotherapy drugs, radiation therapy, and various surgical techniques were developed using rodents, dogs, and monkeys, among others.”
