The prevalence of beliefs and myths amongst cancer patients is a reflection of the level of knowledge in the community regarding cancer. Such beliefs influence the health seeking behaviour of patients and may lead to delay in seeking medical care. The present study revealed that myths and misconceptions are widely prevalent among cancer patients in India. The perception regarding causation of cancer among cancer patients varied from curses, evil eye and spirits to past sins. Only one third of the patients believed that cancer can be detected in its early stages and that it can be cured. The average time taken by patients to report to a doctor after suspecting their disease was 2 years. The majority of patients held fatalistic views about the outcome of cancer. Most (60%) were being discriminated against by their family and society. All these findings highlight that despite considerable medical knowledge of risk factors and treatment modalities, possible social-behavioral strategies for the prevention and control of cancer have not been adequately addressed, especially among South Asian patients.
