“Death from melanoma over the next several decades should stabilize and then decline in light-skinned populations, according to study results.
“This reduction in melanoma mortality — which may be more apparent in younger generations — may be linked to UV exposure patterns, researchers wrote.
“ ‘Independent from screening or treatment, over next decades, death from melanoma is likely to become an increasingly rare event,’ Philippe Autier, MD, director of the International Prevention Research Center in Lyon, France, and colleagues wrote. ‘The temporary epidemic of fatal melanoma was most probably due to excess UV exposure of children that prevailed in 1900 to 1960, and mortality decreases would be due to progressive reductions in UV exposure of children over the last decades.’ ”
“A new study has found that children whose parents are melanoma survivors are not receiving the best possible protection from the sun and ultraviolet radiation.
“This lack of protection can lead to sunburn, increasing the risk of melanoma for the children, who already face a substantially higher risk of developing the skin cancer due to their family history.
“Melanoma is the most serious form of skin cancer as well as one of the most common. In the US, in 2014, it was estimated that 76,100 new melanomas would be diagnosed with around 9,710 people dying from the disease. According to the American Cancer Society, melanoma rates have been rising for the past 30 years.
“The authors of the study, published in Cancer Epidemiology, Biomarkers & Prevention, state that childhood is estimated to be one of the most critical exposure periods for conferring risk.”
“There has been a rise in rates of lifestyle-linked cancers in England.”Liver cancer rose substantially over the past decade – by 70 per cent among men and 60 per cent among women between 2003 and 2012. It now stands as the 18th most common form of cancer in the country, according to new figures by the Office for National Statistics (ONS).
“Rates of malignant melanoma, the most dangerous form of skin cancer, have risen by 78 per cent among men and 48 per cent among women over the same period. Now around 11,300 people are diagnosed with malignant melanoma each year in England, making it the fifth most common cancer.
“The main causes of liver cancer are tobacco, infections with hepatitis B and C ,and excess alcohol consumption.
“Overexposure to the sun has for some time been known to be a major factor in skin cancer cases. Experts have attributed the rise in skin cancer to the popularity of package holidays over the last 50 years.”
“When the sun is shining, many of us are unable to resist a trip to the beach to soak up the rays, despite recommendations that we should cover up to reduce the risk of skin cancer. And now, researchers have discovered why; ultraviolet radiation from the sun releases endorphins – “feel-good” hormones – that act like a drug, making exposure to sunlight addictive.”
“Research conducted at the Texas Biomedical Research Institute, published in the latest issue of the scientific journal Pigment Cell and Melanoma, has established unequivocally in a natural animal model that the incidence of malignant melanoma in adulthood can be dramatically reduced by the consistent use of sunscreen in infancy and childhood.
“According to senior author John L. VandeBerg, Ph.D., the research was driven by the fact that, despite the increasing use of sunscreen in recent decades, the incidence of malignant melanoma, the most aggressive form of skin cancer, continues to increase dramatically. The American Cancer Society estimates that more than 75,000 new cases of melanoma will be diagnosed in the U.S. this year.”
“People sometimes use indoor tanning in the belief that this will prevent burns when they tan outdoors. However, indoor tanning raises the risk of developing melanoma even if a person has never had burns from either indoor or outdoor tanning, according to a study published May 29 in the JNCI: Journal of the National Cancer Institute.
“To test the hypothesis that indoor tanning without burns prevents sunburn and subsequent skin cancer, researchers at the Masonic Cancer Center, Department of Dermatology, and Division of Epidemiology and Community Health, University of Minnesota, Minneapolis used data from a case-control study on indoor tanning and the risk of melanoma. The researchers had detailed information on indoor tanning and sun exposure for the study participants and excluded those who experienced a burn while tanning indoors.”
“Accounting for approximately half of all cancers in the United States, skin cancer is widely recognized as the most common cause of cancer nationwide. More than 3.5 million cases of skin cancer are diagnosed each year, and according to the Skin Cancer Foundation, incidences of skin cancer outnumber all combined cases of breast, colon, lung and prostate cancers.
“With the month of May designated as National Skin Cancer Awareness Month, HemOnc Today highlights 10 issues for oncologists and dermatologists to consider for their patients, as well as the new guideline revisions and research regarding the identification, treatment and management of patients with melanoma and skin cancer.”
