Survey finds most Brazilian women unaware of breast cancer laws
A survey of 2,094 women in Brazil found widespread gaps in breast health knowledge.
About 90% did not know a law guarantees tests within 30 days after suspected breast cancer, and 92% did not know treatment must start within 60 days after diagnosis.
The survey was released during Brazil's October breast cancer awareness campaign and also found that 44% had low or very low levels of information about breast health.
Although 94% knew early-detected breast cancer can be cured, more than half did not feel able to support someone close to them who received a diagnosis.
The findings point to unequal awareness: women using private health care, with higher incomes and older ages scored better than younger, lower-income users of Brazil's public health system.
The lack of knowledge may contribute to late diagnosis; separate data cited in the story found 51% of women treated in the public system in 2025 had stage 3 or 4 cancer.
The survey also found many women confused routine checks with cancer prevention, while six in ten did not know the stages of treatment.
A survey found that about 90% of Brazilian women do not know the law requiring exams after suspected breast cancer within 30 days.
Another 92% do not know the law requiring treatment to begin within 60 days of diagnosis.
The Breast Health Awareness Index 2026 surveyed 2,094 women aged 18 and older.
The survey found that 44% had low or very low levels of information about breast health.
It also found that 76% did not know mammograms are available through Brazil’s public health system at any age when symptoms or medical advice warrant one.

What people are saying
When we bring together these data, both about public services and women's knowledge, we can understand why breast cancer is the cancer that kills the most women in Brazil. The rights guaranteed by public policies or by law can only be claimed if women know about them.
