The Effects of Laughter Yoga and Mindfulness-Based Stress Reduction (MBSR) Practices Applied to Women With Breast Cancer

Breast cancer is defined as the most common type of cancer that causes death among women (Siegel et al. 2019). It constitutes 24% of cancers and 15% of cancer-related deaths in women (T.R. Ministry of Health 2020). According to statistics made towards the end of 2020, there are 7.8 million women in the world who were diagnosed with breast cancer in the last 5 years and are alive. It is estimated that one in every 8 women will develop breast cancer in developed countries (WHO 2021). The Ministry of Health reported the frequency of breast cancer in our country as 45.6/100,000 in women in 2018. The incidence of breast cancer is reported to be higher, especially in the 45-54 age range (TC Ministry of Health 2020). Chemotherapy is one of the most frequently preferred treatment methods in the treatment of breast cancer and can cause serious side effects such as pain, nausea and vomiting, loss of appetite, shortness of breath, mouth sores, fatigue, insomnia, anxiety and depression, and may lead to a deterioration in the quality of life of patients (Waks and Winer 2019, Samami et al. 2021, Sajadian et al. 2017, McFarland et al. 2018, Hamer et al. 2017). In the international and national literature, no study has been found comparing the effects of laughter and mindfulness therapy on the anxiety, depression, quality of life and spiritual well-being experienced by breast cancer patients. In this study, it is planned to investigate the effects of laughter and mindfulness therapy applications on the anxiety, depression, quality of life and spiritual well-being levels of women with breast cancer receiving chemotherapy.
