Pylori, he cause of ulcers is number one), which affects one in every three women at some time in her life.
In most cases, non-melanoma skin cancers are caused by overexposure to ultraviolet radiation – the invisible rays from the sun that can burn the skin. To reduce the risk of skin cancer, dermatologists encourage the public to Be Sun Smart®, including limiting sun exposure and using broad-spectrum sunscreens. Despite these efforts, the incidence of non-melanoma skin cancer continues to rise. Now, several agents – including medicines, foods and vitamins – are being investigated for their chemopreventive properties, or ability to prevent skin cancer.
