Cutaneous malignant melanoma (CM) is the leading cause of skin cancer –related mortality and accounts for approximately 1,250 deaths in Canada each year. It is also one of few cancers continuing to display rates of increasing incidence throughout the world. The past decade has brought significant growth in our understanding of the pathogenesis and clinical managemen t of CM. This evidence-based review synthesizes that knowledge, beginning with a review of the epidemiology and etiology of the disease followed by a broad review of the roles of diagnostic imaging in its management.

Discussion: Sunscreen use among Native Americans (36.4%) appears to be greater than other skin of color users, but less than that of non-Hispanic Whites (40.4%). We postulate that this may be due to the respondents living in states with high UV burden, or an intrinsically greater propensity to burn. Native American populations tend to lack skin cancer screenings by dermatologists and understanding of skin cancer etiology. Efforts are needed to encourage education and dermatologic services to Native American reservations. J Drugs Dermatol. 2019;18(5):420-423. PMID: 31141849 [PubMed - in process]

DISCUSSION AND IMPLICATIONS: The prevalence of sunburn among older adults suggests opportunities to reduce skin cancer risk within this demographic group by preventing overexposure to the sun. The lack of reduced sunburn risk among those who regularly used sun protection may be related to inadequate or inconsistent use of sun protection or the way the sun protection behaviors were measured. Multi-sector approaches to facilitate sun-safety among older adults are warranted and could include targeted efforts focused on those most likely to get sunburned, including men and those with sun-sensitive skin.

(CNN) — Nearly two-thirds of all sunscreens evaluated by the Environmental Working Group would not pass safety tests proposed by the US Food and Drug Administration, the consumer advocacy group announced Wednesday. The group released its analysis as part of its 2019 Guide to Sunscreens, a yearly report on sunscreen safety that the nonprofit began in 2006. The group said it analyzed the ingredients and performance of more than 1,300 products with sun protection factor, or SPF; 750 of those are marketed as beach and sport sunscreens. The analysis involves only a fraction of the sunscreen products sold in the United Sta...

In this study, we reviewed major human studies on the health risks of radiation exposure and showed that sex-related factors may potentially influence the long-term response to radiation exposure. Available data suggest that long-term radiosensitivity in women is higher than that in men who receive a comparable dose of radiation. The report on the biological effects of ionizing radiation (BEIR VII) published in 2006 by the National Academy of Sciences, United States emphasized that women may be at significantly greater risk of suffering and dying from radiation-induced cancer than men exposed to the same dose of radiation....

Conclusions: This meta-analysis demonstrated that CD44 overexpression might be an unfavorable prognostic factor for CRC patients and could be used to predict poor differentiation, lymph node metastasis and distant metastasis. Introduction Although therapies for colorectal cancer (CRC) has improved in recent years, colorectal cancer is still the third most common cause of cancer related death worldwide (1). Metastasis are observed in 25% of patients at initial diagnosis and approximately 50% of patients will develop metastasis (2). Presently, the outcome prediction and the therapy schedule determination of CRC patie...
