Breast cancer is the most common type of cancer in women globally. This situation is similar in our country and it is seen that one out of every four women diagnosed with cancer has breast cancer. Breast cancer is curable with 90% or higher survival rates, especially in the early stages of the disease. As treatment options, chemotherapy, radiotherapy, immunotherapy and surgical methods are used. These methods are applied in different combinations according to the stage and biological subtype of breast cancer. Chemotherapy, which is a frequently used treatment method in cancer treatment, is a systemic treatment method that aims to destroy cancer cells and stop their uncontrolled division. On the other hand, chemotherapy has many negative side effects and causes many physical and emotional symptoms. However, these symptoms can be prevented or reduced with effective treatment and nursing interventions. There are some skills expected from patients in order for the applied treatments and interventions to be effective. Among these skills are; Skills such as symptom management, lifestyle management or coping with the psychological effects of diseases can also be defined as self-management skills. At the stage of gaining these skills, the concept of empowerment of cancer patients emerges. Cancer enhancement; It is a process in which patients specialize in treatment, care and diseases. Empowerment also provides access to high-quality and appropriate care, improved quality of life, better interaction with healthcare professionals, better response to treatment, prevention of complications, and positive attitude towards illness. An empowered patient is an informed patient who takes responsibility for his or her health as much as possible. The vast majority of patients receiving neoadjuvant chemotherapy receive chemotherapy on an outpatient basis. This causes symptoms to be self-managed at home for a long period of time. On the other hand, breast cancer is subjective and every person experiences it differently, and responses to the disease and treatment differ individually. For this reason, it is important to provide individual counseling and professional support in the process of coping with the side effects of chemotherapy. With the development of technology, it is necessary to ensure a harmonious coexistence between nursing care and technology. The theory of 'Technological Competence in Nursing Care', which was developed based on these requirements, is one of the relatively new nursing theories and models. According to the theory, the aim of technological competence in nursing; accepting the patient as a focal point of nursing and benefiting from various technological tools in nursing interventions and defining the individual. According to the International Nurses Association (ICN), tele-nursing; According to the American Nurses Association (ANA), it is defined as the use of communication technologies in nursing to improve patient care, and nursing practices such as obtaining information about the health status of patients, providing care, and patient education by using communication technologies. In this context, tele-nursing is compatible with the concepts and assumptions of the technological competence theory. Women with breast cancer experience numerous physical, psycho-social and sexual complications arising from the disease and treatment methods, and many roles of women are damaged due to the disease. Symptoms experienced during and after chemotherapy treatment negatively affect the patient's empowerment and symptom management. In this process, patients often refer to internet resources to get information about the disease and the symptoms experienced. However, there are doubts about the accuracy of the information obtained and the level of evidence. In a study conducted with people with breast cancer, it was determined that sometimes the information obtained from different internet sources is incomplete or even inconsistent, causing confusion. In another study, it was determined that people with breast cancer think that empowerment is important during the illness and that empowerment issues should include knowledge, beliefs and skills. In this context, it is thought that tele-nursing practices based on technological competence theory will increase empowerment in breast cancer patients and benefit the symptom management self-efficacy. Breast cancer patients are involved in a long and difficult life process from diagnosis. After the shock process of being diagnosed with cancer, it is necessary to be involved in a treatment process quickly. Due to some side effects experienced during the treatment process, they experience some physical, psychological, sexual, occupational and many more problems. While these problems may improve from time to time, there may also be exacerbations. In fact, some adaptation problems may be experienced in the process and patients may even consider stopping the treatment due to the symptoms they experience. In this context, individual counseling and professional support to be provided to patients is very important for the effectiveness of the treatment, which must be continued in a long and difficult process. In a systematic review study evaluating the effectiveness of nursing interventions for breast cancer patients according to the literature, it was determined that nurse-led teaching, guidance, counseling and case management interventions were effective for symptom management. On the other hand, it has been found that the symptom management of patients is poorly controlled despite various guidance in different studies. For this reason, new studies with different models are required in order to provide management skills more powerfully. The concept of patient empowerment is growing in importance in health-related research, and studies show that empowerment improves care outcomes and increases patient satisfaction in those with chronic illness. Thanks to the advances in early diagnosis and treatment technology of breast cancer, survival rates have increased and it has started to be seen as a chronic disease. In most of the studies on the subject, it is seen that augmentation-related interventions are effective, but generally work with breast cancer survivors. However, the fact that the population defined as breast cancer survivors, that is, who completed the breast cancer treatment process, has more experience compared to their newly diagnosed peers and partially knew what to do and how to do it, suggests that they may need an information tool less. In this context, breast cancer patients should be informed about their disease throughout their lives and during the chemotherapy process in order to strengthen their symptom management skills while their treatment continues. When the literature is evaluated, it is seen that information studies conducted with breast cancer patients receiving chemotherapy are generally conducted in the outpatient chemotherapy unit, even while the patient is receiving chemotherapy drugs. In this process, it is thought that breast cancer patients are in the hospital environment and in a crowded environment, they experience the early side effects of the treatment intensely, they have difficulty in managing the symptoms they experience at home and in reaching adequate counseling and support when they need it, and for this reason, they cannot fully benefit from the information/education studies. For this reason, it is expected that informing the patient with tele-nursing practices while the patient is at home during the periods when the patients feel better and the early side effects of chemotherapy decrease, and until the next cure treatment will contribute both in terms of the patient and the skill development expected from the patient. There are some studies evaluating the effects of web-based and mobile application interventions in breast cancer patients. It has been found that the applications made in these studies provide clinical improvement in conditions such as symptom control and management, self-management behaviors, functional exercise compliance, quality of life and drug compliance. No study has been found that evaluates the effects of tele-nursing practice, which is based on technological competence theory and focuses on self-efficacy, especially on empowerment and symptom management, in breast cancer patients receiving neoadjuvant chemotherapy.
