Weight Loss and Breast Cancer

In this study, 300 female patients who underwent laparoscopic sleeve gastrectomy due to morbid obesity in Fatih Sultan Mehmet Training and Research Hospital General Surgery Clinic will be included. The number of samples was calculated by performing impact power analysis. Mamagrophy is recommended for all women over the age of 40 as part of the routine cancer screening program in our country. For this reason, it is assumed that female patients over the age of 40 who have undergone LSG operation have undergone mammography as of 2022. For this reason, the data of these patients will be examined by scanning from the hospital system. Patients who have undergone mammography examination at least 3 years after the LSG operation will be included in the study. The mammograms of the patients who underwent mammography in January 2015 and later will be evaluated. The final diagnosis of breast cancer will be made with the pathology result in patients with suspicious appearance on mamagrophy. If there is a malignancy detected as a result of the examinations, its size and pathology will be recorded. Patients' age, gender, and total weight loss will be recorded. In this retrospective study, we aimed to determine the incidence of breast cancer in patients who had undergone LSG surgery and also to determine whether there was a change in breast cancer compared to weight loss. The patient inclusion criteria are as follows: * 40 years and older (age as of 2022, not the age of operation) * LSG was applied in our clinic due to morbid obesity. * Patients whose mamagrofi images are available in the hospital system The patient exclusion criteria are as follows: * Patients who underwent abdominal surgery again after LSG * Patients whose mamagrophy image is not in the system * Patients with suspicious findings as a result of mammography and who did not undergo additional imaging or biopsy * Patients out of follow-up after the operation
