SOCIETY FOR PREVENTION OF CANCER- Until now, extensive scientific research has been done on various diseases and ways to treat them. Due to the covid outbreak, the focus is shifting towards immunity building and disease prevention. The need for cancer prevention has also been highlighted in the recent discovery of a Japanese scientist, Professor Yoshinori Ohsumi, on the way cells consume themselves, a process that plays a key role in cancer and other diseases. Throughout history, our ancient Vedas and revered Ayurvedic teachings have consistently emphasised the critical importance of prevention. At the heart of this philosophy is the resonating motto "Let the well be well and help the sick," which captures the essence of proactive care. The Atharva Veda, brimming with profound meditative and medical wisdom, is regarded as an invaluable treasure by ancient Indian physicians. The importance of prevention is further emphasised in various sections of the renowned Charaka Samhita, immortalising its enduring relevance. In the contemporary world, the significance of prevention through dietary and lifestyle modifications has resurfaced and regained prominence. Within the realm of medical terminology, this aligns with the concept of 'Public Health, ' which endeavors to avert issues before they manifest in the population, epitomizing the timeless adage: "Prevention is better than cure." In pursuit of its noble objective, the Society for Prevention of Cancer (SPOC) was established in January 2021. Its purpose is to elevate consciousness regarding cancer prevention and foster an understanding of how lifestyle modifications rooted in scientific insights can deter cancer occurrence and recurrence. With utmost humility, we present this book, a profound exposition that encompasses the breadth and depth of cancer prevention, aiming to galvanize a collective movement. It is our sincere aspiration that medical practitioners, public health specialists, aspiring healthcare professionals, and scholars in allied scientific disciplines will unite with us, forging ahead together in this noble endeavor. This book represents the Society's latest endeavor to impart comprehensive knowledge to students and the general public regarding cancer prevention and its prevention of recurrence. It serves as a valuable resource, equipping readers with the necessary information to proactively safeguard against cancer and its reoccurrence.
