Barriers to Early Cancer Diagnosis in India: (A Systematic Review of Patient, Provider, and Health System Level Factors Amid Persistently High Late-Stage Presentation)

Abstract

Cancer remains a major public health challenge in India, with a persistently high proportion of patients presenting at advanced stages of disease. This contributes to reduced survival outcomes, increased treatment costs, and substantial socioeconomic burden on households and the health system.
This systematic narrative review synthesizes evidence on barriers to early cancer diagnosis in India across patient, provider, and health system levels. A structured literature search was conducted using PubMed, Google Scholar, Embase, WHO reports, and selected LMIC studies published between 2005 and 2025. Studies addressing diagnostic delay, stage at presentation, and barriers to early detection were included.
The findings demonstrate that diagnostic delay arises from interacting determinants across three levels. At the patient level, low awareness, stigma, cultural beliefs, and financial constraints delay initial healthcare seeking. At the provider level, low clinical suspicion, misdiagnosis, and inadequate oncology training contribute to delayed referral. At the health system level, inadequate diagnostic infrastructure, workforce shortages, fragmented referral pathways, and urban concentration of cancer services further prolong time to diagnosis. Rural populations are disproportionately affected, with consistently higher rates of Stage III–IV presentation.
This review concludes that late-stage cancer diagnosis in India is primarily a structural health system problem requiring integrated reforms in primary care strengthening, diagnostic capacity expansion, referral system integration, and financial protection mechanisms.
