to an increased quality of life. Research primary conducted with breast cancer survivors has shown that interventions to increase the identification of benefits to a highly stressful experience like cancer diagnosis can improve quality of life. Post traumatic growth is significant to cancer diagnosis due to the potentially life threatening nature of the diagnosis. Individuals may be forced to consider their own mortality and may adapt by altering the way they relate to others, the world, and even themselves. Cancer presents individuals with a major health threat that often challenges one's sense of self as they attempt to navigate changes to their lives as a result of diagnosis and treatment. Meaning making is the effort to restore order and purpose to people's lives that has been changed so drastically by the disease. Meaning making can be a part of a positive growth process that occurs after diagnosis with cancer and is associated with greater quality of life and well-being. Behavioral In addition to behavioral responses to cognitive reactions to diagnosis and treatment, the field of psycho-oncology address behaviors associated with risk of developing cancer and behaviors that place individuals at risk of poor disease outcomes. Included in this domain of interest are preventive medicine behaviors of smoking cessation and use of skin protection as well as adherence to treatment regimens. Health promoting behaviors and preventive medicine Behavior modification to reduce the risk of developing cancer is a major public health concern due to health care costs associated with individuals being treated for cancer. Behavior change falls squarely within the interests of the field of psycho-oncology due to the psychological factors associated with implementing behavior change. Chief among behaviors that are targeted to decrease individuals' risk for cancer are smoking and alcohol consumption, diet and exercise, and sun exposure. These health behaviors are known to increase the likelihood of developing cancer in addition to myriad other health conditions. Engagement with screening procedures is also of importance with regard to cancer prevention and in some cancers an underutilized resource. Fear and anxiety are barriers for some to getting screened for cancer. However, cancer screening presents the opportunity to catch tumors that are present in very early stages and avoid intensive, systemic treatments in favor or more acute and localized treatments with a higher cancer of cure (e.g., surgical resection). Behavioral modification is also relevant to improving the quality of life of those
