The Lancet Oncology Commission report on Cancer in the Commonwealth was launched today at the 2026 Commonwealth Heads of Government Meeting (CHOGM) in Antigua, during the side event ‘Cancer Control and Health Systems Strengthening in the Commonwealth’. The event brought together researchers, clinicians, policymakers, civil society representatives, First Ladies and spouses of Commonwealth Heads of Government.
The report is the result of a three-year collaboration between The Lancet Oncology Commission and the Commonwealth Secretariat. It sets out an urgent agenda to address the rapidly rising cancer burden across the Commonwealth’s 56 member countries, home to around 2.7 billion people, while delivering wider health and economic benefits.
Key findings include:
- Cancer carries substantial economic and social costs, making effective control a strategic necessity for an economically resilient Commonwealth.
- Comprehensive scale-up could generate an estimated return of US$16–US$24 for every US$1 invested, depending on national income, geography and valuation method used.
- Annual new cancer cases worldwide are projected to reach 35 million by 2050—77% more than in 2022.
- Expanding treatment and imaging capacity, while improving the quality of care, offers the greatest opportunity to avert cancer deaths.
The launch opened with a session chaired by Cabinet Minister in Antigua and Barbuda, Minister of Housing and Works and Member of Parliament for St. John’s Rural East, H.E. Maria Vanessa Bird-Browne.
Presenting the report findings, Chair of The Lancet Oncology Commission, Professor Rifat Atun, said:
“A comprehensive scale-up of treatment, imaging, and quality of care will deliver benefits of between $140 and $793 billion, a return of between four dollars and twenty dollars on every dollar invested.
Investment in cancer control also pays dividends beyond the clinic: in 2022 alone, health expenditure on cancer control generated an estimated $82·9 billion in gross value added across Commonwealth economies through direct, spillover, and induced effects, benefits that strengthen national productivity and fiscal resilience well beyond health ministries.”
Cancer care in the Commonwealth
The report introduces the Commonwealth Observatory for Health Systems and Cancer Control. The database brings together data on around 800 variables related to health systems and cancer control in the Commonwealth, including essential contextual information on countries, such as demographic, epidemiological, and economic indicators, and analyses of national cancer control plans.
The Officer-in-Charge of the Social Development, Youth and Gender Division at the Commonwealth Secretariat, Jennifer Namgyal said:
“The Commonwealth’s strength lies in partnership and collective action. We bring member countries, experts and strategic partners together around shared priorities, connecting evidence, policy and implementation to support country-led solutions.
“The Lancet Oncology Commission shows what this model can achieve: combining evidence and expertise with the Commonwealth’s convening power to identify practical opportunities for stronger cancer control and health systems. Through partnership, knowledge exchange and collective learning, we can build more equitable and resilient health systems and improve outcomes across the Commonwealth.”

More than 14 First Ladies and spouses of Commonwealth Heads of Government attended, including Mr Cyril Laryea, the spouse of the Commonwealth Secretary-General, Hon Shirley Botchwey. Participants encouraged the spouses, many of whom are prominent cancer-care advocates, to use their public profiles to draw greater attention to the growing cancer burden.
At CHOGM, a panel of ministers, officials and diplomats considered six priorities for equitable cancer control across the Commonwealth:
- Adopt targeted policies that widen access to affordable, high-quality cancer technologies.
- Transform care delivery to improve availability, quality and equity.
- Accelerate innovation in cancer prevention, diagnosis and treatment.
- Put patients and civil society at the centre of policy and delivery.
- Invest in education and professional development for the cancer care workforce.
- Strengthen timely, reliable data systems and comprehensive national cancer-control plans.
The Commission says delivery will require sustained political leadership, funding, inclusive coalitions and shared tools to help countries collaborate.
The Commission first presented preliminary findings at the inaugural Commonwealth Health Coordination Forum in Geneva on 16 May 2026. The CHOGM launch now brings the agenda directly to Heads of Government, with a clear message: investing in cancer control will save lives, strengthen health systems and support economic resilience.
