Cancer care represents a complex challenge that extends far beyond biological considerations alone. Emotional, social, and behavioral elements play equally crucial roles in shaping how patients experience and navigate their cancer journey. However, most research has examined these aspects in isolation, with psychological processes receiving the primary focus. While factors like stigma, fear of cancer returning, emotional distress, and social support networks have proven critically important, few studies have investigated them together within a unified framework. Additionally, researchers have paid limited attention to the broader healthcare environment and compassionate design approaches that could substantially influence patient outcomes and treatment experiences. This research introduces the Psychosocial Cancer Behavior Model (PsyCaB) as a comprehensive framework for understanding cancer-related behaviors more completely. The model seeks to advance behavioral research in cancer treatment while strengthening the translation of behavioral science and psychosocial findings into real-world practice. Its foundation draws from extensive research covering cancer awareness, risk perception, stigma, and the psychosocial experiences of both patients and healthcare learners. The PsyCaB Model conceptualizes the relationship between behavior and cancer as an interactive, dynamic process shaped by multiple interconnected influences. These include cancer knowledge and awareness levels, individual perceptions of personal risk, emotional responses such as fear and distress, social elements including stigma and support from family and friends, and broader system-level components like healthcare institutions, policies, and societal norms. The model suggests these factors work together over time to influence how cancer prevention, treatment, and care unfold. By incorporating multiple stakeholders - including families, healthcare providers, and policymakers - the model provides a more complete understanding than existing approaches, which typically center primarily on the patient. This framework connects psychological factors with social and systemic influences, creating a more thorough view of cancer care behaviors that can inform better strategies for meeting patients' psychological needs and improving their overall treatment journey. The model serves as a foundation for future research, a guide for developing psychosocial interventions, and a resource for informing cancer prevention, treatment, and care policies. It emphasizes the critical need to integrate psychological support into medical care, as research demonstrates that patients who receive psychological support alongside medical treatment show decreased anxiety levels and better adherence to their treatment protocols, potentially leading to improved outcomes and quality of life.

Cancer care presents a multifaceted challenge that goes well beyond medical and biological factors. The emotional, social, and behavioral dimensions are just as important in determining how patients move through their cancer experience. Yet most studies have looked at these elements separately, focusing mainly on psychological aspects. Important factors such as stigma, fear of recurrence, emotional distress, and social support systems have been recognized as vital, but very few studies have examined how they work together as part of a complete picture. Furthermore, researchers have given little consideration to the overall healthcare setting and compassionate design principles that could significantly impact patient outcomes and treatment experiences. This study presents the Psychosocial Cancer Behavior Model (PsyCaB) as an all-encompassing framework for better understanding behaviors related to cancer. The model aims to improve behavioral research in cancer treatment and enhance how behavioral science and psychosocial discoveries are applied in actual clinical settings. It builds on extensive research that covers cancer awareness, risk perception, stigma, and the psychosocial experiences of patients and healthcare trainees alike. The PsyCaB Model views the connection between behavior and cancer as an interactive and evolving process influenced by various interconnected factors. These factors include levels of cancer knowledge and awareness, how individuals perceive their personal risk, emotional reactions like fear and distress, social aspects such as stigma and support from loved ones, and larger system-wide elements including healthcare organizations, policies, and societal attitudes. The model proposes that these components interact continuously to shape cancer prevention, treatment, and care practices. Through its inclusion of multiple parties - families, healthcare professionals, and policymakers - the model offers a more comprehensive perspective than current approaches that focus mainly on patients. This framework links psychological elements with social and systemic factors, providing a more complete picture of cancer care behaviors that can guide better strategies for addressing patients' psychological needs and enhancing their overall treatment experience. The model functions as a basis for future studies, a blueprint for creating psychosocial interventions, and a tool for shaping cancer prevention, treatment, and care policies. It highlights the essential importance of incorporating psychological support into medical treatment, as studies show that patients receiving psychological care along with medical treatment experience reduced anxiety and better compliance with treatment plans, which may result in improved outcomes and enhanced quality of life.
