Literature Review On Skin Cancer - 2421 Words

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 notShow MoreRelatedSkin Cancer : The Most Common Form Of Cancer1334 Words   |  6 PagesSkin cancer is the most common form of cancer in the United States. Skin cancer encompasses three types of cancers: basal cell carcinoma (BCC), squamous cell carcinoma (SCC), and melanoma—the most dangerous of the three. The underlying cause of all types of skin cancers is exposure to ultraviolet (UV) light. UV light consists of three various types of UV rays including ultraviolet A (UVA), ultraviolet B (UVB), and ultraviolet C (UVC). Of the three types, UVA is most damaging to skin as it can damageRead MoreBreast Cancer : Causes, Signs And Symptoms And Risk Factors1539 Words   |  7 PagesLITERATURE REVIEW INTRODUCTION: This section is going to review literature on overview of breast cancer, its causes, signs and symptoms and risk factors. It will also look at literature on screening methods of breast cancer, particularly mammogram. OVERVIEW OF BREAST CANCER According to Rodney et al (2003), breast cancer is the commonly occurring cancer in women, responsible for one third of all malignancies in females. It is said to be the second to lung cancer as a cause of cancer mortality andRead MoreUsing The Experimental Or Quasi Experimental Method With Variables As Well As The Correlational Method1148 Words   |  5 Pagesreading chapter six â€Å"the research problem† from Introduction to Research and Medical Literature for Health Professionals (2013), the concept of study replication is a helpful technique as it’s a relatable research method for health care professions. It would not only help with the research process but adding past experiences will provide improved research and accuracy.

Other simple preventive measures include: performing hand hygiene, using sterile gloves, application of suitable skin antiseptic, and ensuring that the skin prep agent dries up prior to insertion of the central line. Since central lines access the most important vein which is closer to the heart, when it remains in place for a longer period especially in intensive care units, it mayRead MoreAssessment Toolss : Assessment Forms And Methods Of CIPN1680 Words   |  7 Pagesautonomic is the National Cancer Institute Common Terminology for Adverse Events (NCI-CTCAE) (Argyriou et al., 2012). This tool grades the level of toxicities, including neurotoxicity, on a scale from â€Å"0†, which is absence of symptoms, to â€Å"5†, which is death. A systematic review of literature by Curcio (2016) resulted in sixteen articles meeting the review criteria and seven different scales that were examined for their efficacy in assessing CIPN in cancer. That review proposed a combination of subjectiveRead MoreWhat Is MR Linacs?1246 Words   |  5 Pagesaffects the magnet. Depending on the orientation of the magnet versus the linear accelerator, the magnet could have an effect on the electron gun and skin dose (Keall et al., 2014). Modifications were made to the electron gun, to avoid the challenge of the magnet having an effect on the direction the electrons were accelerated (Keall et al., 2014). Skin dose was also a concern for one of the two proposed orientations of magnet and LINAC, and a few potential solutions were discussed (Keall et al., 2014)Read MorePaper On Breast Cancer1365 Words   |  6 PagesIntroduction Cancer of the breast is the most common type of non-skin cancer affecting women.
