Luckily, skin cancer is almost entirely preventable and high-profile awareness and information campaigns telling Australians how to save their skin have been in place for several decades. But there are still a lot of misconceptions about skin cancer and sun protection. Cancer Council Australia's Skin Cancer Committee has developed a number of position statements and fact sheets addressing common myths and misunderstandings and providing clear information and advice aimed at helping Australians reduce their skin cancer risk. Many of the statements have been developed with input from other expert health organisations, particularly the Australasian College of Dermatologists. Ultraviolet UV radiation from the sun doesn't just damage the skin. It can lead to eye complaints such as cataracts and cancers on the surface of the eye.

Each year, more than , Americans are diagnosed with colorectal cancer. No one knows if or when cancer in the colon or rectum will develop, but understanding the risk factors for colorectal cancer may help you take measures to reduce the likelihood of getting the disease. Colorectal cancer forms when the DNA in cells in the colon or rectum develop mutations that may make them unable to control growth and division. In many cases, these mutated cells die or are attacked by the immune system. But some mutated cells may escape the immune system and grow out of control, forming a tumor in the colon or rectum. The exact cause of colorectal cancer is not known, but certain risk factors are strongly linked to the disease, including diet, tobacco smoking and heavy alcohol use.
