Introduction: As the healthcare programs focus on the relatively higher incidence, women have a fair level of awareness of breast cancer. Breast of male hence ignored in the community. Studies from India have shown that medical care is often taken in an advanced stage because of lack of awareness, and the aggressive nature of breast cancer in Indian men and seen at quite an early age. Video-assisted knowledge teachings about awareness of male breast cancer among adult males would improve their understanding and exploration of the perceptions and opinions of Indian male cancers. Aim: To determine the effectiveness of video-assisted education on male breast cancer knowledge among adult males in the city of Wardha. Methods and Materials: One group pretest and posttest design with a quantitative research approach has been used in this interventional study design. This study has been carried out in community set up. Sample size was100. Validated Pretested predesigned structured questionnaires were used. In Microsoft excel sheet, data collected was entered. SPSS-software was used to perform the statistical analysis. Frequencies and percentages for categorical variables have been presented. Results: The pre-test findings show that 15(15%) of the adult males had a poor level of knowledge score, 50(50%) had average knowledge and 31(31%) of them had good knowledge and 4(4%) of them had found a very good level of knowledge. After video-assisted teaching in the post-test 3(3%) had a good knowledge score and 97(97%) had very good knowledge, thus it shows that after the post-test the knowledge score was increased. The Mean value of the pre-test is 9.32 and the post-test is 23.14 (p-value is 0.001), the calculated t-value is 35.47. Hence it indicates that Teaching aided with video was effective. The post-test score was significantly associated with population variables such as occupation and bad habits. The post-testing knowledge score with demographic variables such as age, religion, family type, education, marital status, dietary pattern, and area of residence was not significantly linked. Conclusion: The study shows that the expected teaching on male breast cancer has helped adult males to gain a better understanding of the nature of the disease and to take measures to prevent male breast cancer.
