Introduction: Breast cancer is the leading cause of death in women. Many studies of adjuvant therapy have used the Quran recitation (later will be mentioned as the murotal approach). The murotal approach has been shown to induce feelings of well-being, enhance therapeutic response, and aid in patient healing. This study aimed to analyze the effect of the murotal approach on lymphocytic cell activity in inducing programmed cancer cell necrosis in a breast cancer mouse model. Methods: After testing in a fully randomized design using 24 female mice (Mus musculus) BALB/c strain, a real-world experimental study with a control group design method. The mice were divided into four groups: negative control (K-), positive control (K+), treatment group (P1) which receiving the murotal approach for 2 hours and 30 minutes per day for a week, and the (P2) which receiving the murotal approach for 30 minutes in five times a day for a week. Mice were subcutaneously injected with DMBA 0.56 mg/20 g every 2 days for 3 weeks. The murotal approach was using specifically in Surah al-Faatihah and Al-Baaqarah from Qori' Al-Mathrud. Cancer tissue was harvested 5 weeks after her. The data were analyzed using the Kruskal-Wallis hypothesis test. Results: There was a significant difference (P<0.05) in the effect between the P2 treatment group that received murotal therapy for 30 minutes at each prayer time and the other groups. The efficacy of treatment murotal for 2 hours and 30 minutes per day does not affect the extent of lymphocytic infiltration. Conclusion: From the research, the dosage of murotal therapy to increase the degree of lymphocyte infiltration is for 30 minutes five times a day, or during prayer time.
