Why it matters
Same disease. Different endings.
Where a woman lives decides whether her cancer is found early, and whether she survives it. The gap comes down to awareness and access, and both can change.

Fewer diagnoses, more deaths. In poorer countries, fewer women are diagnosed, yet more die, because cancer is often found late, when it is far harder to treat.

It can change
It has been done before.
Between the 1980s and 2020, high-income countries cut breast cancer death rates by 40%. The World Health Organization's Global Breast Cancer Initiative aims to bring that progress everywhere, saving 2.5 million lives by 2040.

Awareness is where early starts.
