In the last issue of our Health Science News Page we discussed aspects of skin cancer and the damage caused by excessive sun exposure. The most common risk factor of non-melanoma skin cancer is excessive exposure sunlight. However, it is important to note that the non-melanoma skin cancers, basal and squamous cell carcinomas are not as lethal as melanoma which can also occur on areas of the skin not exposed to the sun. Sun exposure can cause free radical damage in the skin cells leading to DNA damage and skin ageing, and may eventually cause skin cancer, however, that is not the only risk factor.
With the arrival of summer people become acutely aware of sun exposure, skin cancers and the use of sunscreen. Worldwide, one in three diagnosed cancers is classified under skin cancer. Basal cell carcinoma, squamous cell carcinoma, and melanoma are the most common forms of skin cancers, and malignant melanoma is the most fatal.
According to the American Cancer Society, it is estimated that nearly 9,500 people in the US are diagnosed with skin cancer every day and 161,790 new cases of melanoma are estimated to be diagnosed in the US in 2017. Males over 50 and women younger than 50 are reported to have an increased risk of developing melanoma. In fact, melanoma is the second most common form of cancer in women between the ages of 15-29. The annual cost for treating melanoma has grown faster than the annual treatment costs for all other cancers combined.
Scientists at the Dr. Rath Research Institute in California have published a new study which demonstrates for the first time that only a consistent daily supplementation with vitamin C can protect against heart disease. The study shows that irregular intakes of this essential micronutrient do not achieve the same beneficial effect. Published in the International Journal of Cardiovascular Research, the study further supports the importance of a consistent, sufficient intake of vitamin C in ensuring an optimum profile of blood risk factors, vascular wall integrity, and optimal cardiovascular health.
