Challenge 01 · BREAST CANCER
Detecting cancer early saves lives — yet in many countries, participation in screening programmes still falls short of target. Rethink how to encourage, support and enable more women to take part.
The scale of the problem
new breast cancer cases diagnosed worldwide every year
deaths each year — many following late-stage diagnosis

01_ Context
Breast cancer screening is a preventive public health programme designed to detect cancer before symptoms appear. In many countries, women within specific age groups are regularly invited to undergo a screening mammogram — a low-dose X-ray of the breast that can detect small abnormalities long before they can be felt or cause symptoms.
Detecting breast cancer at an early stage significantly improves the chances of successful treatment, increases survival and often allows for less aggressive treatments with fewer long-term consequences.
Despite these benefits, participation in screening programmes remains below target in many countries. Research shows that non-attendance is rarely driven by a single factor. Women's decisions to participate are influenced by a combination of personal beliefs, practical barriers, previous healthcare experiences, social circumstances and the way screening services are organised and communicated.
Your mission
For this hackathon, your task is to rethink how healthcare systems can encourage, support and enable more women to participate in screening.

02_Where to innovate
We have broken this challenge down into four areas where innovation is needed. Pick one as your focus, or design a solution that bridges several.
How might we help more women understand the value of breast cancer screening and feel motivated to get screened?
Breast cancer screening is designed to detect cancer before symptoms appear, when treatment is more likely to be successful and less invasive. However, many women who are invited to screening choose not to attend because they do not believe they are personally at risk or are unaware of the benefits of early detection.
Unlike women who seek medical care because they feel unwell, screening programmes target healthy individuals who may not perceive an immediate need to attend. As a result, participation depends on whether women understand the purpose of screening, recognise its relevance to them and feel motivated to act.
Information about breast cancer screening comes from many different sources, including healthcare professionals, public health campaigns, family and friends, traditional media and social media. The quality, clarity and consistency of these messages can vary considerably, making it difficult for women to make informed decisions. A clear recommendation from a trusted clinician, particularly in primary care or gynaecology, is consistently identified as one of the strongest predictors of screening participation.

System constraints
These are fixed by regulation, infrastructure or national policy — design around them, not against them.
