Objective:The aim of present study is to identify the breast cancer screening barriers among the women with breast cancer of Malwa region of Punjab,*** study was conducted at three government hospitals representing almost all districts of Malwa ***:The quantitative research design was followed using empirical research *** was carried out by one-to-one interview by the field investigator and research *** of 363 breast cancer patient has been interviewed through the scheduled questionnaire and results has been recorded for further *** this study,five barriers are described namely as personal barriers,socio-cultural barriers,economic barriers,healthsystem barriers,and treatment barriers which contains various questions regarding barriers to breast cancer *** analysis methods have been used for the analysis to access the socio-demographic profile of *** has been obtained with the help of 5-point liker *** logistic model was ***:Majority of participants were in the age groups 50-60 years(31.1%,112/363).Majority of these women(47.4%,171/363)were illiterate and most of them were *** major barriers to breast cancer screening faced by most of the women were having no knowledge about screening services(90.9%,329/363),the importance of early diagnosis(90.9%,329/363),different screening methods(95.5%,347/363)and place of availing screening services(91.2%,330/363)misguided belief in God and fate(81.5%,295/363)and preferring duties than taking care of health(70.2%,254/363).Education qualification(odds ratio[OR]0.74,β'=-0.309,t=-5.357,P=0.000)and socioeconomic class(OR 1.43,β’=0.354,t=3.399,P=0.001)were found to be significant determinant of the barriers among ***:The survey was conducted in the women between the age 40-60 years and as an outcome,the unawareness about screening services,fatalistic attitude,fear of being diagnosed with the c
