Background Cervical cancer is the second most common cancer and the leading cause of cancer death in women in sub-Saharan Africa (SSA). Methods Trends in the incidence of cervical cancer are examined for a period of 10–25 years in 10 population-based cancer registries across eight SSA countries (Gambia, Kenya, Malawi, Mauritius, Seychelles, South Africa, Uganda and Zimbabwe). A total of 21,990 cases of cervical cancer were included in the analyses. Results Incidence rates had increased in all registries for some or all of the periods studied, except for Mauritius with a constant annual 2.5% decline. Eastern Cape and Blantyre (Malawi) registries showed significant increases over time, with the most rapid being in Blantyre (7.9% annually). In Kampala (Uganda), a significant increase was noted (2.2%) until 2006, followed by a non-significant decline. In Eldoret, a decrease (1998–2002) was followed by a significant increase (9.5%) from 2002 to 2016. Conclusion Overall, cervical cancer incidence has been increasing in SSA. The current high-level advocacy to reduce the burden of cervical cancer in SSA needs to be translated into support for prevention (vaccination against human papillomavirus and population-wide screening), with careful monitoring of results through population-based registries.

Trends in the incidence of cancer in the population of Kyadondo County, Uganda—which comprises the city of Kampala and a peri‐urban hinterland—are presented for a period of 25 years (1991‐2015) based on data collected by the Kampala Cancer Registry. Incidence rates have risen overall—age‐adjusted rates are some 25% higher in 2011 to 2015 compared with 1991 to 1995. The biggest absolute increases have been in cancers of the prostate, breast and cervix, with rates of some 100% (prostate), 70% (breast) and 45% (cervix) higher in 2010 to 2015 than in 1991 to 1995. There were also increases in the incidence of cancers of the esophagus and colon‐rectum (statistically significant in men), while the incidence of liver cancer—the fifth most common in this population—increased until 2007, and subsequently declined. By far the most commonly registered cancer over the 25‐year period was Kaposi sarcoma, but the incidence has declined, consistent with the decreasing population‐prevalence of HIV. Non‐Hodgkin lymphomas, also AIDS‐related, increased in incidence until 2006/2007 and then declined—possibly as a result of availability of antiretroviral therapy. The trends reflect the changing lifestyles of this urban African population, as well as the consequences of the epidemic of HIV/AIDS and the availability of treatment with ARVs. At the same time, it highlights the fact that the decreases in cancer of the cervix observed in high and upper‐middle income countries are not a consequence of changes in lifestyle, but demand active intervention through screening (and, in the longer term, vaccination).
