Introduction:Obesity is a known risk factor for the development of cancers, and a significant proportion of the population may be at risk of developing cancer owing to their weight status. There is acknowledged societal stigma towards people living with obesity, which can influence health behaviors and deter help seeking, such as cancer screening. Healthcare professionals' attitudes and views toward people living with obesity may adversely affect the patient-professional interface and treatment.Methods: A systematic review was carried out which aimed to explore the impact of living with obesity on the uptake of three main cancer-screening services: breast, cervical, and colorectal.Results: Ten studies were included in the review. Three main areas were identified from both a patient and healthcare professional perspective: barriers and challenges to screening, gender issues, and disparities in the population living with obesity.
Conclusion:Further research is needed to improve uptake of cancer screening services, and for education on weight bias, which is often unconscious, to be considered for healthcare professionals working in cancer screening services. This may help to increase the incidence of early differential diagnosis of potential cancers and improve health outcomes for people living with obesity.

| INTRODUCTIONObesity (BMI kg/m 2 ) is a known risk factor for the development of cancers 1,2 with evidence suggesting an increase in cancers such as breast in postmenopausal women, colorectal (higher risk in males), endometrial, esophageal adenocarcinoma, gall bladder, and renal. 1,3 Gender differences in cancer risk among people living with obesity, including the incidence of esophageal, liver, and colorectal cancer, due in part to disparities in body fat distribution between men and women, 4 The rates of obesity have tripled globally since 1975, and as of 2016, the World Health Organization estimated there were 650 million people living with obesity. 5 By 2030, the rates are predicted to increase to one in five women and one in seven men, meaning over 1 billion people across the globe will be living with obesity. 6 Notably,This is an open access article under the terms of the Creative Commons Attribution-NonCommercial-NoDerivs License, which permits use and distribution in any medium, provided the original work is properly cited, the use is non-commercial and no modifications or adaptations are made.
