Preface As the population ages, the burden of cancer is expected to grow, placing an increasing demand on primary care providers (PCPs) to manage various aspects of cancer care. While oncologists lead the specialized treatment of cancer, PCPs play a crucial role in the early detection, management, and support of patients throughout their cancer journey. From screening and diagnosis to managing treatment side effects and coordinating care, the involvement of PCPs is vital for improving patient outcomes and quality of life. This book is designed to provide primary care providers with a comprehensive understanding of the basics of cancer care. It covers essential topics such as the most common types of cancer, standard treatment modalities, management of complications, and cancer care nutrition. Additionally, the book explores alternative therapies and the evolving role of precision medicine in cancer care. With the growing complexity of cancer treatments and the increasing need for collaborative care, this book serves as a guide to help PCPs better support their patients with cancer, whether by initiating appropriate referrals, managing treatment side effects, or providing nutritional, emotional, and palliative care. By understanding cancer from a multidisciplinary perspective, PCPs can ensure that their patients receive holistic, patient-centered care throughout their cancer journey Huynh Wynn Tran, MD, FACP, FACR Associated Professor of Medicine and Pharmacy CEO/Founder of Wynn Medical Center Clinics Los Angeles, California, USA
