The aim of the study is to assess body image disturbances and well being among post mastectomy patients at selected hospitals of Punjab. A descriptive non experimental research design was adopted to conduct the present study. Convenient sampling technique was used to select 60 post mastectomy patients. Self structured BIS (Body image scale) was used to assess body image disturbances and standardized FACT+B tool was used to assess well being among post mastectomy patients. The findings revealed that out of 60 subjects, 43% study subjects had body image fully and partially disturbed and 62% of the study subjects had inadequate well being. A statistically significant relationship was found between body image disturbances and well being of post mastectomy patients at p<0.05. Body image was found to be associated with age and educational level of the patient at p<0.05. Well being was also found to be associated with age and stage of cancer. The study concluded that younger age, advance stage of cancer and higher education could influence the body image and well being among post mastectomy patients.
