A new study is here. It says we can stop many cancer cases. The World Health Organization did this study. They look at how we live.
The study looked at many countries. It found millions of cancer cases can stop. About 37% of cancers are from things we can avoid. These are smoking and bad food.
Leaders are listening. They want to stop cancer better. They say stopping cancer is a big job.
Some cancers happen because of age. But most cancers do not. They happen from things we see each day. We can change these things. We can have good health.
