Abstract : Breast cancer has become the most common cancer in India. [GLOBCAN 2020]. These patients have either modified radical mastectomy (MRM) or breast conservation surgery as a curative surgical option as per the stage, suitability and preference of the patient. The aim of the study was to find out the difference in QOL of the patients who had completed their treatment with respect to type of surgery. Fifty-two patients who had completed their treatment with surgery (either MRM or BCS) followed by chemotherapy and radiotherapy for breast cancer were enrolled into the study after informed consent. After 1 year of completion of the treatment, the response to the QOL questionnaires from city of hope were obtained. The QOL scores were tabulated and mean of the QOL outcomes were compared with independent T test or mann-whitney U test and analysed with SPSS V21. The mean age group of the patients undergoing MRM was 46.7 ± 10.2 years and BCS was 41.7 ± 7.2 years. There was no difference in Patients undergoing MRM or BCS according to age group (P = 0.234), education level. (P= 0.399), socio-economic status (0.345). Patients in both groups had coped well with physical, psychological, social and spiritual wellbeing related issues and there was no difference on these QOL parameters after 1-year of completion of treatment as per the type of surgery. Our patient population seems to be maintaining a good quality of life and in control of their different aspects in life and there seems no difference in gross QOL in terms of type of surgery in patients of eastern India. As QOL is not much different in both the groups clinical decision and patient preference may guide the decision about type of surgery in patients.
