80% of Women in Low- and Middle-Income Countries Diagnosed With Cancer Late, Study Finds

A recent study has revealed a stark disparity in early cancer diagnosis among women worldwide. In low- and middle-income countries like India and parts of Africa, less than 20% of women are diagnosed with cancer at an early stage, meaning that 80% of cases, including breast and cervical cancer, are detected late. In contrast, in high-income countries, 3 to 4 out of 5 women are diagnosed early, improving their chances of successful treatment.


The VenusCancer Study

The findings come from the VenusCancer study, conducted by the Cancer Survival Group at the London School of Hygiene & Tropical Medicine. The research analyzed diagnosis trends, treatment adherence, and survival rates for over 275,000 women across 39 countries, highlighting major gaps in cancer care and early detection.


Ovarian Cancer: The Silent Killer

The study points out that ovarian cancer has the lowest early detection rates, with only 20% of cases diagnosed early. Often called a “silent killer,” ovarian cancer presents vague symptoms such as abdominal pain or bloating, which can go unnoticed for long periods, delaying treatment and reducing survival chances.


Older Women at Greater Risk

The research also indicates that older women are less likely to receive treatment according to international guidelines compared with younger patients. While early-stage cancer is often treated with surgery, adherence to standard care protocols varies widely between countries.

Additionally, metastatic breast cancer — which spreads to other parts of the body — is rare in high-income countries (less than 10%) but ranges from 2% to 44% in low- and middle-income countries, underscoring the impact of delayed diagnosis.


Implications for Global Cancer Care

Professor Aleimani, part of the study team, emphasized the need for governments to invest in cancer control programs and implement effective cancer record-keeping systems. These measures are expected to support WHO’s global plan to eliminate breast and cervical cancer, particularly in resource-limited regions.


💡 Takeaway

Early detection remains crucial for survival, yet millions of women in low- and middle-income countries continue to face delayed diagnosis. Strengthening healthcare infrastructure, raising awareness, and improving adherence to treatment protocols are key steps toward reducing cancer mortality among women worldwide.
