Breast cancer advocacy is when people work together to help make sure more people learn about breast cancer and how to prevent it. It's like when your teacher reminds you every day to wash your hands to stay healthy -- people who do breast cancer advocacy are reminding other people every day to check their breasts regularly and go to the doctor if they notice any changes. Advocates also work to make sure that people who have breast cancer get the help and support they need, like getting the right treatment, finding support groups, and spreading awareness so people know how serious breast cancer can be. In short, breast cancer advocacy is all about making sure fewer people get sick, and helping the people who do get sick get better.
