Summary:

• **What the study is about**: Scientists are using government money to study whether ivermectin, a medicine normally used to treat worms in animals and people, might help fight cancer. This is a surprising idea because there isn't much evidence that this medicine works against cancer.

• **Why scientists are concerned**: Many doctors and researchers think this study is a waste of money because ivermectin hasn't been proven to cure cancer in the past. They worry that giving people false hope about a deworming medicine could prevent them from getting real cancer treatments that actually work.
