## TL;DR

The Calabar population-based cancer registry recorded 719 new cancers in two local government areas over 2009 to 2013; breast and cervical cancer made up three in five cancers in women and prostate cancer was the commonest in men.

## Summary

The Calabar Cancer Registry covers two local government areas of Calabar, the capital of Cross River State, 375,196 inhabitants in 2006. Over 2009 to 2013 it registered 719 new cancers, 320 in men and 399 in women, and the paper presents incidence rates by site, sex and age.

- Findings: Age-standardised incidence was 78.8 per 100,000 in men and 86.9 per 100,000 in women.; Breast and cervical cancers accounted for 60.4% of cancers in women; breast cancer (35 per 100,000) was almost twice as common as cervical cancer (21 per 100,000) and occurred in younger women.; Prostate cancer was the commonest cancer in men (50.8 per 100,000); Hodgkin lymphoma was common in both sexes and HIV-related cancers were recorded in moderate numbers.
- What it means: A third measured population rate for Nigeria, from the south-east, with prostate, breast and cervical cancer again leading.
- Caveats: A small population and small numbers, so site-specific rates are imprecise.; Population denominators rest on the 2006 census.
