Literature Review Skin cancers have become increasingly prevalent over the last 30 years, with 87,000 new melanoma diagnoses per year in the United States (American Cancer Association, 2016). With regards to skin melanoma, medical professionals struggle most with the diagnosis rather than the treatment (Ferris et al., 2017). Therefore, it is important for the medical community to focus on diagnosis- related struggles. Pigmented Lesions and Routine Dermopathy There are various types of pigmented lesions— blue nevi, lentigo, melanocytic nevi, seborrheic keratoses— that resemble benign melanoma growths and physicians can overlook them, making melanoma diagnosis challenging (Marghoob et al., 2009). An excisional biopsy, that removes…show more content…
To prove the inefficiency of standard dermopathy, the study compared an experimental group that received perceptual expertise training, and a control group which did not receive any training; they concluded that the difference between the mean score of the control and the trained group was statistically significant and hence, current dermatologists require more training. However, the study’s sample was from a medical school, not certified dermatologists; this makes the results less conclusive because certified physicians usually examine melanoma. Within their control results, they also showed that the control group had improved scores between the pre-melanoma detection task and the post-melanoma detection task. Considering that all other factors were kept constant, the results prove that some form of melanoma detection experience gives physicians a better chance of detecting melanoma. This then raises doubt on the performance of inexperienced physicians and their role in misdiagnosing melanoma. Other studies, whilst recognising experience playing a vital role in better diagnosis, suggest alternate techniques, to improve melanoma diagnoses. The ABCDEs of melanoma The basis of melanoma diagnosis is often referred to as the ABCDEs of melanoma by physicians: asymmetry, border irregularity, colour, diameter, and evolution of the pigment. Dermatologists are trained to view lesions not
