“…To our knowledge, it is also unique anywhere in the world to conduct small and medium skin surgeries in an MU. Few reports of the use of an MU for skin cancer screening are found in developed countries, probably due to a more well-developed health care structure and a population with better information on means of preventing this cancer[5,19]. Since changes in the health care system are usually slow, the use of an MU provides faster specialized medical care to the people with difficult access to health services.…”

BackgroundSkin cancer is the most common malignancy in the white population worldwide. In Brazil, the National Cancer Institute (INCA) estimates that in 2010 there will be 119,780 and 5,930 new cases of non-melanoma skin cancer and melanoma, respectively. The aim of this study was to evaluate the use of a mobile unit in the diagnosis and treatment of skin cancer in several poor regions of Brazil.MethodsThe diagnosis of skin cancer was accomplished through active medical screening in the prevention Mobile Unit (MU) of Barretos Cancer Hospital (BCH). The study population consisted of patients examined in the MU between 2004 and 2007, and their suspicious lesions were subjected to histopathological evaluation. Data were collected prospectively from standardized forms and analyzed.ResultsDuring the screening, 17,857 consultations were carried out. A total of 2012 (11.2%) cases of skin cancer were diagnosed. The predominant histological type reported was basal cell carcinoma (n = 1,642 or 81.6%), followed by squamous cell carcinoma (n = 303 or 15.1%), Bowen's disease (n = 25 or 1.2%), malignant melanoma (n = 23 or 1.1%), basosquamous cell carcinoma (n = 3 or 0.1%), miscellaneous lesions (12 or 0.6%), and metatypical carcinoma (n = 4 or 0.2%). Only 0.6% of lesions were stage III. There were no stage IV non-melanoma skin lesions, as well as no melanomas stages III and IV, found.ConclusionsIt was observed that the MU can be a useful tool for early skin cancer diagnosis and treatment. This program probably is important, especially in developing countries with inadequate public health systems and social inequality.

“…McDonald subsequently summarized US melanoma screening efforts. 41 In the same context, Rhodes comprehensively emphasized public and professional education for the primary and secondary prevention of melanoma, and recommended personal responsibility in this process to ultimately reduce morbidity and mortality. 42 Koh et al subsequently provided a framework in which to evaluate screening of melanoma.…”

“…(10) Case-finding should be a continuing process and not a ‘once and for all’ project” [ 14 ]. Those criteria were subsequently supplemented and specified: the disease must have serious consequences and a high prevalence in order to justify screening efforts, and it must progress slowly and not be immediately life threatening [ 15 , 16 ]. All those conditions are fulfilled by melanoma.…”

Screening for melanoma has been advocated for many years because early detection and excision have been regarded as the most important measure to lower mortality from that neoplasm. In the past decade, concern has been raised by epidemiologists that screening might result in excision chiefly of “inconsequential cancer,” i.e., melanomas that would never have progressed into life-threatening tumors, a phenomenon referred to by the misleading term “overdiagnosis.” Without any firm evidence, that speculation has been embraced worldwide, and incipient melanomas have been trivialized. At the same time, efforts at early detection of melanoma have continued and have resulted in biopsy of pigmented lesions at a progressively earlier stage, such as lesions with a diameter of only 2, 3, or 4 mm. Those tiny lesions often lack sufficient criteria for clinical and histopathologic diagnosis, the result being true overdiagnoses, i.e., misdiagnoses of melanocytic nevi as melanoma. This is especially true if available criteria for histopathologic diagnosis are diminuished even further by incomplete excision of lesions. The reliability of histopathologic diagnosis is far higher in excisional biopsies of lesions that were given some more time to develop changes that make them recognizable. Biopsy of pigmented lesions with a diameter of 6 mm has been found to result in a far higher yield of melanomas. In addition to better clinical judgment, slight postponement of biopsies bears the promise of substantial improvement of the reliability of histopathologic diagnosis, and of alleviating true overdiagnoses.
