Background: Late presentation of patients at advanced stages when little or no benefit can be derived from any form of therapy is the hallmark of breast cancer in Nigerian women. Recent global cancer statistics indicate rising global incidence of breast cancer and the increase is occurring at a faster rate in populations of the developing countries that hitherto enjoyed low incidence of the disease. Worried by this prevailing situation and with recent data suggesting that health behavior may be influenced by level of awareness about breast cancer, a cross-sectional study was designed to assess the knowledge, attitude and practices of community-dwelling women in Nigeria towards breast cancer.

Prostate cancer (CaP) is the leading cancer among men of African descent in the USA, Caribbean, and Sub-Saharan Africa (SSA). The estimated number of CaP deaths in SSA during 2008 was more than five times that among African Americans and is expected to double in Africa by 2030. We summarize publicly available CaP data and collected data from the men of African descent and Carcinoma of the Prostate (MADCaP) Consortium and the African Caribbean Cancer Consortium (AC3) to evaluate CaP incidence and mortality in men of African descent worldwide. CaP incidence and mortality are highest in men of African descent in the USA and the Caribbean. Tumor stage and grade were highest in SSA. We report a higher proportion of T1 stage prostate tumors in countries with greater percent gross domestic product spent on health care and physicians per 100,000 persons. We also observed that regions with a higher proportion of advanced tumors reported lower mortality rates. This finding suggests that CaP is underdiagnosed and/or underreported in SSA men. Nonetheless, CaP incidence and mortality represent a significant public health problem in men of African descent around the world.

Morbidity and mortality from breast cancer have continued to be a source of concern to surgeons in many countries. Over a period of 10 years--January 1987 to December 1996--117 patients presented with carcinoma of the breast at the University of Benin Teaching Hospital in Benin City, Nigeria. The case files of 77 patients were available and were analysed retrospectively. There were 75 females and 2 males. Sixty seven per cent of the female patients had large and grossly advanced lesions. Most of them were multiparous and they practiced prolonged breastfeeding. Seventy eight per cent of the patients delayed for over 3 months before presenting to the hospital. The five-year survival was 8.7%. We conclude that carcinoma of the breast is common in this community and that most of the patients present late to the hospital.
