The PsyCaB model has been developed based on a synthesis of evidence, which was done in various populations and settings with a specific focus on cancer awareness and stigma, psychosocial experiences, and health-related behavior. PsyCaB is not based on purely theoretical abstraction rather than models, but rather is based on empirical evidence about knowledge of, as well as experience with, cancer. As a result, the model has been informed by information on the general understanding of cancer and the information that is relevant to the real world experiences of diagnosis and treatment. It has been more and more clear that the solid cancer models should be based on the knowledge of how people view and react to cancer in the framework of their daily existence (Institute of Medicine, 2008; Holland et al., 2015). The vast amount of literature on cancer awareness and risk perception demonstrates that knowledge does not always translate into action. Although the risk factors and the warning signs of cancer are well comprehended, people often define their personal risk as low, especially among younger generations of the population, who might take the incidence of cancer in others as the issue of concern but not the issue of self. In a research, students in institutions of higher learning generally had a wider recognition of typical cancer signs and risk factors, but most of them reported that they thought they had a low chance of contracting the disease (Elliason, 2026). This perception of personal invulnerability has been linked to lower rates of preventive behavior, such as screening and seeking advice from a professional. These results highlight the limitations of awareness-based programs in situations where individuals do not perceive personal relevance to the risk (Weinstein, 1987; Wardle et al., 2015). However, behavior cannot be explained by knowledge only. There is also a need to consider the emotional and social states that bring awareness to action. Disease-related stigma has been pointed out as a major obstacle on numerous occasions. Even in educated settings, it might be discouraged to openly discuss cancer, and there might be a delay in seeking treatment due to the fear of being judged, excluded, or discriminated against. This can be seen in one of the studies, which stated that students were afraid of being labeled and treated differently after a diagnosis (Elliason et al., 2025). Such attitudes may postpone action, which is confirmed by Else Quest et al. (2009) and Phelan et al. (2014), even in cases when the people are aware of the risk of cancer. The value of emotional experience has also been widely reported. Holland et al. (2015), Stanton et al. (2015), and Stokes, Douglas, and Ellis (2009) identify emotional distress (physical or psychological), social isolation, interpersonal problems, and financial troubles as also frequently reported among people living with cancer and likely to delay treatment adherence and overall coping abilities. A Ghanaian study established that cancer diagnosis and treatment cause significant anxiety, fear, and disruptions in social and familial life. On the other hand, women who had access to useful social support and received good care indicated a better coping capacity (Elliason et al., 2025). These results highlight the fact that emotional well-being and relational support are to be viewed as core elements of cancer care, but not as marginal distracters. Taken together, the combined evidence suggests that, as far as cancer-related behavior is concerned, neither knowledge nor individual choice is sufficient to bring the change. Instead, interaction between consciousness, perceived risk, emotional response, social interaction and institutional context brings along change. Wardle et al. (2015) and Elliason (2026) described that students might have adequate cancer knowledge but have low screening and help-seeking behavior; they have low personal risk perception and continue to hold stigma, which prevents their involvement in preventive actions. All the factors that may affect treatment adherence and patient-reported quality of life may include emotional distress, the intensity of possible support, and constraints of the healthcare system (Holland et al., 2015; Elliason et al., 2025). The PsyCaB model combines these interacting determinants. Cancer management has been organized as an adaptive model where awareness, risk perception, stigma, emotional response, and social factors all play a role in influencing behavior. The model provides a more detailed explanation of cancer behavior due to the utilization of both theoretical models and empirical experience. It explains how psychosocial factors impact cancer prevention, treatment, and care on an individual level but also against family dynamics, healthcare systems, and the broader social context, highlighting the interconnectedness of these influences on health outcomes.

Researchers developed the PsyCaB model by combining evidence from multiple populations and settings, with particular attention to cancer awareness, stigma, psychological experiences, and health behaviors. Rather than relying solely on theoretical concepts, PsyCaB draws from real-world evidence about how people understand and experience cancer. The model incorporates both general cancer knowledge and information relevant to actual diagnosis and treatment experiences. There is growing recognition that effective cancer models must account for how people perceive and respond to cancer within their everyday lives (Institute of Medicine, 2008; Holland et al., 2015). Extensive research on cancer awareness and risk perception shows that knowledge alone does not guarantee action. While people often understand cancer risk factors and warning signs well, they frequently view their personal risk as minimal. This pattern is particularly common among younger people, who may acknowledge cancer as a concern for others while not considering it personally relevant. Research found that college students typically demonstrated good awareness of cancer symptoms and risk factors, yet most believed they had little chance of developing the disease themselves (Elliason, 2026). This sense of personal invulnerability correlates with reduced engagement in preventive behaviors like screening and professional consultation. These findings reveal the shortcomings of awareness-focused programs when individuals fail to see personal relevance in the risk (Weinstein, 1987; Wardle et al., 2015). Knowledge alone cannot account for behavior patterns. Emotional and social factors that bridge awareness and action must also be considered. Cancer-related stigma frequently emerges as a significant barrier. Even in well-educated environments, open cancer discussions may be discouraged, and fear of judgment, social exclusion, or discrimination can delay treatment seeking. Research showed that students worried about being labeled and receiving different treatment following a diagnosis (Elliason et al., 2025). These concerns can postpone necessary action, as documented by Else Quest et al. (2009) and Phelan et al. (2014), even when people recognize cancer risks. Emotional experiences also play a crucial role. Research by Holland et al. (2015), Stanton et al. (2015), and Stokes, Douglas, and Ellis (2009) shows that people with cancer commonly experience emotional distress, social isolation, relationship difficulties, and financial challenges, all of which can hinder treatment compliance and coping abilities. A study in Ghana found that cancer diagnosis and treatment created substantial anxiety, fear, and disruptions to social and family relationships. Conversely, women with access to meaningful social support and quality care demonstrated better coping skills (Elliason et al., 2025). These findings emphasize that emotional wellness and relationship support should be considered essential components of cancer care, not peripheral concerns. The collective evidence indicates that neither knowledge nor individual decision-making alone drives cancer-related behavior change. Instead, change emerges from the interaction between awareness, perceived risk, emotional responses, social relationships, and institutional factors. Research by Wardle et al. (2015) and Elliason (2026) showed that while students possessed adequate cancer knowledge, they demonstrated limited screening and help-seeking behaviors due to low personal risk perception and persistent stigma that discouraged preventive actions. Factors affecting treatment adherence and quality of life include emotional distress, available support systems, and healthcare system limitations (Holland et al., 2015; Elliason et al., 2025). The PsyCaB model integrates these interconnected factors. It frames cancer management as an adaptive process where awareness, risk perception, stigma, emotional responses, and social elements all influence behavior. By incorporating both theoretical frameworks and empirical findings, the model offers a comprehensive understanding of cancer behavior. It demonstrates how psychological and social factors affect cancer prevention, treatment, and care at the individual level while also considering family relationships, healthcare systems, and broader social contexts, emphasizing how these various influences interconnect to shape health outcomes.
