## Cancer Epidemiology in India ### Most Common Cancer in India (Overall) **Key Point:** According to the latest epidemiological data — including GLOBOCAN 2020 and the Indian Council of Medical Research (ICMR) / National Cancer Registry Programme (NCRP) reports — **breast cancer** has surpassed cervical cancer to become the most common cancer overall in India, accounting for approximately 13–14% of all cancers. ### Current Cancer Burden in India (GLOBOCAN 2020) **High-Yield:** The top cancers by incidence in India (both sexes combined): 1. **Breast cancer**: ~1.78 lakh new cases annually (~13.5% of all cancers) — **#1 overall** 2. **Cervical cancer**: ~1.24 lakh new cases annually (~9.4%) — #1 in women for many years, now #2 3. **Oral/Lip cancer**: ~1.35 lakh new cases (tobacco-related) 4. **Lung cancer**: ~0.72 lakh new cases annually 5. **Colorectal cancer**: ~0.57 lakh new cases annually ### Why Breast Cancer Now Leads 1. Rapid urbanization and lifestyle changes (obesity, sedentary habits, late childbearing, reduced breastfeeding) 2. Declining cervical cancer incidence due to improved (though still limited) screening awareness 3. Increasing life expectancy in Indian women 4. Rising incidence in both urban and rural areas ### Important Distinction **Clinical Pearl:** Cervical cancer was historically the most common cancer **in Indian women** and remains the most common **gynecological cancer** in India. However, when considering **all cancers overall** (both sexes combined) or even **cancers in women alone** per the most recent data (GLOBOCAN 2020), breast cancer now ranks **#1**. Exam questions citing "latest data" or "current epidemiology" should be answered as breast cancer. ### Global Context Breast cancer is also the most common cancer globally (GLOBOCAN 2020), making India's current pattern consistent with worldwide trends. **Mnemonic:** **BCION** — Breast Cancer Is #1 Overall Now (in India, per latest data) > *Reference: GLOBOCAN 2020 (IARC); ICMR-NCRP Three-Year Report of Population Based Cancer Registries 2012–2014; Park's Textbook of Preventive and Social Medicine, 26th edition.*
