“…11 This and other early studies were based on hospital out-patient and private practice records and mortality 12,13 or they were concerned with melanomas in the black population, where follow-up information was difficult to obtain because of the population mobility and the absence of accurate official statistics. [14][15][16] Additional factors affecting the results of some of these studies were the absence of population-based data, accurate population figures or cancer registration.…”

Malignant melanoma in Cape Town, South Africa

et al. 1998

There is a world-wide increase in the incidence of cutaneous malignant melanoma among white people. Absence of accurate population-based data on the incidence of melanoma in South Africa prompted a study to determine the incidence, anatomical sites and pathological details of melanoma in Cape Town. In a prospective study from 1 January 1990 to 31 December 1995, all the histopathology reports of melanoma presenting in a geographically defined area of Cape Town, were actively retrieved from every pathologist practising in this area. The data evaluated included information on age, sex, ethnic group and location of residence. Details of melanoma comprised body site, Clark level of invasion, Breslow thickness in millimetres and histogenetic type. The histology slides were reviewed by a panel in those cases where the recorded information was ambiguous or incomplete. A final number of 595 reports of primary invasive cutaneous melanomas in white people was analysed. Of these 50.3% were men and 49.7% women. The overall age-standardized incidence rate was 24.4 per 100,000 per annum (27.5 for men and 22.2 for women). There was no change in the incidence rate over the study period. Most melanomas in both sexes (74% of women and 71% of men) were < 1.5 mm Breslow thickness. Results of this study indicate a high incidence rate of melanoma in white South Africans, comparable with that in Australia, which demands urgent preventive health measures.

“…A study from South Africa on melanoma in persons of mixed ancestry purported to demonstrate the lowest incidence in the world. 16 These results could have been influenced by the study not being population-based and thus incidence rates were not calculated.…”

“…Incidence rates between 0.9 and 1.2 per 100 000 among black South Africans have been reported. 7,8 However, the advantage of this is offset by a tendency to late presentation. Some 70% of melanomas in black Africans are reported to be on the lower limbs, with 90% of those being below the ankle, with acral lentiginous melanoma being the most common subtype.…”

Skin cancer awareness and sunscreen use among outpatients of a South African hospital: need for vigorous public education

et al. 2018

Background: Melanoma incidence among white South Africans is increasing. Among black individuals, melanoma is associated with advanced stage at presentation and significant mortality.Objectives: A study was undertaken to assess the perception of skin cancer risk, knowledge of skin cancer, and understanding of the importance and use of sunscreens among South Africans.Methods: A cross-sectional survey was conducted in general outpatients over four months at a large central hospital in Durban, South Africa.Results: Only half the white respondents reported regular use of a sunscreen. Among black and Indian respondents, the number was substantially lower. Less than 20% of white respondents had ever checked their skin for suspicious moles. Most black patients were not aware that they are at risk of skin cancer, and only 10% were aware of the risk of developing skin cancers on acral sites and nails.Conclusions: There is a worrying lack of knowledge about skin cancer and sun protection behaviours among all South Africans. Given the increase in melanoma incidence and racial disparities in survival rates, it is imperative to target each population with effective, culturally sensitive educational programmes.
