Obesity as a Risk Factor for Different Cancers: Systematic Review

According to the World Health Organization (WHO) categorization of Body Max Index, obesity is frequently measured in clinical practice by expressing body weight as a function of height (BMI). There is good evidence that obesity raises the risk of many cancers, such as esophageal adenocarcinoma, postmenopausal breast, pancreatic, colorectal, endometrial, liver cancer and kidney cancer. The study aims to summarize current evidence regarding Obesity as a risk factor for different cancers. The PubMed database and EBSCO Information Services were utilised to choose the articles. In our review, all pertinent articles related to our subject and other publications were used. Other articles that have nothing to do with this subject were not included. The group members looked through a certain format in which the data had been extracted. Obesity is a significant risk factor for the occurrence and progression of many cancer types especially when it comes to GI cancers such as colorectal, gastric, and liver cancer. This has been linked to multiple pathophysiological reasons such as lower immunological response in obese patients. However, it is worth noting that in many cases strong evidence has not been established for obesity as a risk factor, and some studies suggest that sex may play a critical role when it comes to obesity as a risk factor for cancer.
