Kenji Lopez speaks to ecancer about his talks at WCC 2024 on legislation – a powerful tool for promoting massive changes.

He says two sessions at WCC focused on the barriers women face in breast cancer control and the role of law in this area.

Nine Latin American countries have cancer control laws, while Mexico is developing a national plan.

In comparison, the US has had a cancer control law for over 50 years.

WHO urges national plans for public health.

Mexico's lack of specific legislation fails to protect health rights, but recent amendments support families of children with cancer.

Late diagnoses and cultural factors contribute to rising breast cancer cases, which are projected to increase by 40% by 2040.

Mr Lopez highlights how legislation in countries can improve cancer care and screening.
