“…The average (mean/median) age at breast cancer diagnosis was in the 40s in the large majority of studies. Most studies involved collection of data through structured or semistructured questionnaires, usually administered by the researchers or medical staff around the time of diagnosis, but four studies were conducted retrospectively using medical records [11] , [12] , [21] , [25] . Information on ethnicity was provided in only one study, which stated that its subjects were all black [29] .…”

PurposeAfrica has low breast cancer incidence rates but high mortality rates from this disease due to poor survival. Delays in presentation and diagnosis are major determinants of breast cancer survival, but these have not been comprehensively investigated in Africa.MethodsMEDLINE, Embase, and Global Health were searched to identify studies reporting on delays in presentation and/or diagnosis of breast cancer published between January 1, 2000 and May 31, 2016. Data were synthesized in narrative, tabular, and graphical forms. Meta-analyses were not possible due to between-study differences in the way delays were reported.ResultsTwenty-one studies were included in the review. Study-specific average times between symptom recognition and presentation to a health care provider ranged from less than 1 to 4 months in North Africa and from less than 3 to greater than 6 months in sub-Saharan Africa. Study-specific average times from presentation to diagnosis were less than 1 month in North Africa but ranged from less than 3 to greater than 6 months in sub-Saharan Africa. Reported reasons for these delays included patient-mediated (e.g., socioeconomic factors) and health system–mediated factors (e.g., referral pathways).ConclusionsThis systematic review revealed marked delays in presentation and diagnosis of breast cancer in Africa. Identification of their drivers is crucial to the development of appropriate control strategies in the continent.

“…22 It has to be noted that there is a considerable delay between first symptoms and presentation to health care practitioner; a recent systematic review found between 3 to over 6 months delay, and there is an additional 3-6 months interval between first presentation to health care practitioner and confirmation of diagnosis of breast cancer in SSA 23 ; while in comparison, the median time from first presentation at the health care setting to diagnosis in 2004-2005 was on average 25 days (range:14-44 days) in the Aarhus county of Denmark. The median overall time from first symptom recognition to diagnosis has been estimated at 7.9 months in Accra, Ghana, 24 8.5 months in Western Cape, South Africa, at more than 10 months in Abidjan, Cote d'Ivoire 25 and at 15 months in rural Rwanda 26 ; in contrast, in 2006, about 30% of all breast cancer cases in England, Scotland and Wales were diagnosed asymptomatically by screening. 27 Some reasons for late presentation in SSA include low breast cancer awareness, 28 difficult access to healthcare (both physical 29 and economic), fear, distrust of conventional medicine and belief in alternative sources of healing.…”

Breast cancer is the leading cancer diagnosis and second most common cause of cancer deaths in sub‐Saharan Africa (SSA). Yet, there are few population‐level survival data from Africa and none on the survival differences by stage at diagnosis. Here, we estimate breast cancer survival within SSA by area, stage and country‐level human development index (HDI). We obtained data on a random sample of 2,588 breast cancer incident cases, diagnosed in 2008–2015 from 14 population‐based cancer registries in 12 countries (Benin, Cote d'Ivoire, Ethiopia, Kenya, Mali, Mauritius, Mozambique, Namibia, Seychelles, South Africa, Uganda and Zimbabwe) through the African Cancer Registry Network. Of these, 2,311 were included for survival analyses. The 1‐, 3‐ and 5‐year observed and relative survival (RS) were estimated by registry, stage and country‐level HDI. We equally estimated the excess hazards adjusting for potential confounders. Among patients with known stage, 64.9% were diagnosed in late stages, with 18.4% being metastatic at diagnosis. The RS varied by registry, ranging from 21.6%(8.2–39.8) at Year 3 in Bulawayo to 84.5% (70.6–93.5) in Namibia. Patients diagnosed at early stages had a 3‐year RS of 78% (71.6–83.3) in contrast to 40.3% (34.9–45.7) at advanced stages (III and IV). The overall RS at Year 1 was 86.1% (84.4–87.6), 65.8% (63.5–68.1) at Year 3 and 59.0% (56.3–61.6) at Year 5. Age at diagnosis was not independently associated with increased mortality risk after adjusting for the effect of stage and country‐level HDI. In conclusion, downstaging breast cancer at diagnosis and improving access to quality care could be pivotal in improving breast cancer survival outcomes in Africa.

“…The prognosis of most all the patients living with tumor is aggravated by the latest diagnosis and by the lake of specific treatment. For Toure et al and Takongmo et al [19,20] the treatment given to the patients in low income countries is mainly palliative. All these observations show that tumors must be considered as health public mater in the Democratic Republic of Congo and are advocacy arguments for diagnosis, prevention, and treatment of cancer in low income countries.…”

Tumors had been misdiagnosed and under-documented for longtime in Africa. The Democratic Republic of Congo (DRC) has not any cancer registry available up today. The National Cancer Registry is an important tool to deal with cancer management, especially for the National Cancer Plan and cancer prevention. The African Cancer Registry Network (AFCRN) is trying to help many Countries to hold their national Registries in hope to provide tumors' data. Despite National Cancer Registry, hospital Registries can be used for preliminary researches. This is a retrospective study performed to determine epidemiological and clinical data of tumors in Lubumbashi City, the second city in DRC, especially in the mines' hospital during the period from 2007 to 2017. The authors collected data from 350 patients aged from 2 and 94 years. The average age was 46.3 ± 17.9 years. There were 299 Females and 51 males; means 85.4 vs 14.6%. Tumors of the female reproductive system accounted for 72.9%. Diagnosis was made by echography in 59.7% of cases. Palliative care was the main treatment in 51% of cases. This study has enlightened the fact that tumors are a serious problem of health in the Democratic Republic of Congo and there are many challenges to improve cancer survival in this country.
