The Effect of Pectoralis Major Block type 1 (PECS 1) on intraoperative general anesthetic requirements and postoperative analgesic requirements for breast cancer patients Undergoing Mastectomy

Abstract

reast cancer is the top cancer in women both in the developed and the developing world. The incidence of breast cancer is increasing in the developing world due to increase life expectancy, increase urbanization and adoption of western lifestyles (Anderson et al., 2008). According to the American Cancer Society (ACS), breast cancer makes up 25 percent of all new cancer diagnoses in women globally. In 2012, nearly 1.7 million new cases were diagnosed worldwide. Survival rates vary worldwide but are improving overall. In countries with advanced care, the rate is 80 to 90 percent for those with a first-stage diagnosis, and 24 percent if diagnosis occurs at a later stage (American Cancer Society, Cancer Facts & Figures 2018).
