Ahmed1,2, Ahmed A. Osman 3* & Ahlam Mukhtar4,5  \nAcetylcholinesterase enzyme (AChE) activity is impaired by a variety of inhibitors including organophosphorus pesticides, leading to the accumulation of acetylcholine. In this study, we aimed to determine the association between cancer and the blood level of the (AChE) . This is a multicenter hospital-based case–control study conducted in the Radiation and Isotopes Center Khartoum, and Institute of Nuclear Medicine and Molecular Biology and Oncology Gezira. One hundred and fifty participants, half of them cancer patients and half cancer free were recruited. All participants were screened for demographic, environmental, occupational, and clinical characteristics. Blood for the (AChE) activity test was drawn from participants in the two groups. The mean age of the participants was 40.6 ± 14.8 years. Geographical distribution showed the Central Region of Sudan had the highest rate of cancer, followed by North State, Khartoum State, West State, and East State. The most common tumor subtype was breast cancer, followed by leukemia, colon, esophageal, and prostate cancer. Inferential analysis revealed significantly impaired (AChE) activity among cancer patients compared to controls (53.4 ± 20.3% vs. 93.8 ± 8.8, p-value 0.001). There was a significant statistical association between impaired (AChE) activity and cancer. (AChE) activity might be applied in the future as a diagnostic biomarker and therapeutic target. Further large sample and molecular studies are recommended.  \nKeywords Acetylcholinesterase enzyme (AChE), Acetylcholine (ACh), Cancer, Sudan  \nAbbreviations  \nAChE Acetylcholinesterase enzyme  \nACh Acetylcholine  \nCAT Choline acetyltransferase ROS Reactive oxygen stress  \nRICK Radiation and Isotopes Center Khartoum  \nINMO Institute of Nuclear Medicine and Molecular Biology and Oncology HCC Hepatocellular carcinoma  \nAD Alzheimer’s disease  \nThe etiology of cancer involves several causes where cells start to grow abnormally in an uncontrollable manner. Cancer cells tend to invade adjoining parts of the body and diffuse to affect other organs. It is the second cause of death with nearly 10 million deaths worldwide, the lung cancer is the leading cause of death followed by colorectal, liver, stomach, and breast cancers1. Only 5–10% of all cancer cases can be attributed to genetic defects, whereas the remaining 90–95% have their roots in the environment and lifestyle, including cigarette smoking, fried foods, red meat, alcohol, sun exposure, environmental pollutants, infections, stress, obesity, and physical inactivity2. In most cases, genetic mutations are present while the associated risk factors start the process of changing the normal pattern of cellular proliferation and differentiation. Scholars identified genes such as oncogenes, tumor suppressor genes, apoptosis genes, and DNA repair genes to be responsible for mutations  \n1Columbia University Hospital, New York, NY, USA. 2Faculty of Medicine, and Health Sciences, Managil University for Sciences & Technology, Managil, Sudan. 3Independant Scholar, Chesterfield, UK. 4Stack Laboratory, Federal Ministry of Health, Khartoum, Sudan. 5Radiation and Isotopes Center Khartoum, Federal Ministry of Health,  \nKhartoum, Sudan.* email: [sudanup.ao@gmail.com](sudanup.ao@gmail.com)  \n[www. nature.com/scientificreports/](www. nature.com/scientificreports/)  \nand changing the normal cell division processes3,4. (AChE) plays an important role in the formation of apoptosome and the regulation ofthe apoptotic process5. Decrease levels of (AChE) produce substantial DNA damage, reactive oxygen stress (ROS), and rise micronuclei frequencies, leading to the increased risk of genotoxic processes6,7.
