Abstract
OBJECTIVESCancer is a major cause of morbidity and mortality worldwide, and it is an increasing problem in developing countries. Estimation of the incidence of cancer is important, especially in regions with limited epidemiological data on cancer. Therefore, the aim of this study was to provide an updated report on the incidence of cancers in the Tobruk region in eastern Libya.METHODSData on cancer patients from the records of the Department of Histopathology of Tobruk Medical Centre from January 2013 to June 2020 were included.RESULTSIn total, 402 cases were recorded. Men patients accounted for 30.3% (n=122) of cases, and women patients represented 69.6% (n=280). The overall mean age at the time of the first diagnosis was 49.0±17.1 years. The most common malignancies were breast and uterine cancer in women (18.4%, n=74; 15.9%, n=64, respectively), colorectal cancer (11.6%, n=47; 26 in women and 21 in men), bladder cancer (8.2%, n=33; 8 in women and 25 in men), and thyroid cancer (8.0%, n=32; 23 in women and 9 in men).CONCLUSIONSBreast and uterine cancers were the most common cancers in women, and bladder and colorectal cancer were the most common cancers in men, followed by colorectal cancer in both genders. These data will help health authorities launch preventive plans for cancer in the region. Further studies to identify aetiological factors and cancer-related risk factors need to be conducted in the region.
Highlights
The rate of cancer incidence is growing in developing countries because of aging and several cancer-associated risk factors, which include smoking, obesity, physical inactivity, and some chronic infections; for instance, hepatitis B virus and hepatitis C virus (HCV) are associated with liver cancer, human papillomavirus is linked to cervical cancer, and Helicobacter pylori is associated with stomach cancer [2]

Summary
Cancer is one of the leading health problems throughout the world; in 2018, the World Health Organization estimated that. The majority of cancer-related deaths occur in developing countries [1]. Most developing countries have little data about the rate of cancer incidence [3]. In the Tobruk region in eastern Libya, there is no cancer registry for the collection and management of data on cancer patients. Cancer registries play an important role in planning and performing research on the causes of cancer, and are useful for evaluating prevention and control programs target-
