Breast cancer is a significant health problem worldwide and a complex and overwhelming disease both physically and psychologically.  Stress is caused by an existing stress-causing factor or stressor. Dealing with breast cancer can cause a great deal of stress. Emotional support to breast cancer patients can essentially give cancer treatment a power boost as experts believe there is a link between emotional support, education and health outcomes. Nurse scientist should support in conducting research on breast cancer stress and emotional support. Clinical protocol should be modified based on evidence based practice research. The role of breast care nurses needs clarification and should include a focus on psychosocial assessment and emotional support for women. The value of the breast care nurse researcher role as part of the multidisciplinary team in providing quality care for women has been increasingly recognised nationally and internationally as part of evidence based best practice for breast care.
