Journal Title: International Journal of Medical Research Professionals - Year 2018, Vol 4, Issue 2
Abstract
Introduction: The mortality rate of breast cancer varies proportionally with age. In India, the average age of developing breast cancer has shifted over the last few decades and younger women are being affected. In view of the above, present study was undertaken to study the incidence of various types of breast cancer according to age and histopathological grade was noted at the time of diagnosis of breast cancer. Materials and Methods: The present retrospective study was comprised of 100 cases of breast cancer reported at GSVM Medical College, Kanpur. The material was derived from the files of the department. The information comprised of demographic characteristics, such as age, site of lesion and histo-pathological characteristics. The specimens were selected from mastectomy specimens received from surgical department for routine histopathological examinations. Data so obtained was analyzed and expressed as number and percentage as required. Results: Peak incidence of breast carcinoma was during fifth decade of life, followed by fourth decade of life. Mean age at diagnosis of breast carcinoma was 45.66 years. Age of youngest patient was 25 years (2 cases), whereas oldest patient was 72 years of age. Most common carcinoma of all age groups was infiltrating duct carcinoma. All cases of 3rd, 7th and 8th decade of life were of infiltrating duct carcinoma. Infiltrating duct carcinoma was most common in 5th decade. Infiltrating lobular carcinoma was most common in 4th decade. Infiltrating duct carcinoma and lobular carcinoma was most common in 5th decade. One case of infiltrating duct carcinoma and mucinous carcinoma was present in 5th decade (age 42 years) One case of papillary carcinoma was present in 6th decade (age 55 years). Most of breast carcinomas were of G2 histopathological grade (65%). Gl:G2:G3 ratio was about 1:5:1.5 i e. 2:10:3. Conclusion: The present study concludes that the peak incidence of breast cancer is in the 5th decade followed by 4th decade. Mean age of developing breast cancer revealed was 45.6 years. Infiltrating duct carcinoma was the most common histological type, comprising of 86% of all cases. Most common histopathological grade was G2.
