Cancer screening plays a significant part in detecting cancer at an early stage to reduce morbidity and mortality. As per WHO, the Primary Health Centres (PHCs) handles the vast majority of a person's health requirements. In India, the National Health Mission (NHM) aims to provide universal access to fair, accessible, and high-quality health-care services that are accountable and responsive to people's needs. Under the NHM, these PHCs are established to cover a population of 30,000 in rural areas and 20,000 in hilly, tribal, and desert areas. PHC in India is considered a basic health unit to offer integrated curative and preventive health care to the rural population as near to the people as feasible, with an emphasis on preventive and promotive components of health care to all the sections of the society. The PHCs in Tamil Nadu state have an effective system for managing cancer, beginning with early screening to palliative care. Currently, the state is managing 1806 PHCs. The objective of this study was to examine individuals' awareness of cancer screening services offered at PHCs. Using the multistage cluster sampling technique, Coimbatore District was segmented based on its taluks, and from each taluk, data were collected using a random sampling method. A cross-sectional study with a sample size of 387 responses was obtained from residents. Results show that the people's awareness towards cancer and its screening is substantially low. The key findings indicate that a significant proportion of individuals lack awareness about the screening tests for breast (23%), cervical (30%), and oral (28%) cancers that are offered at primary health centres. The study presents recommendations, that improve early screening which is pertinent to promote equity in healthcare.
