Skin cancer is the most common cancer in Australia, with over 80% of newly diagnosed cancers being skin cancers. The main cause of skin cancer is overexposure to UV radiation from the sun. There are three main types of skin cancer - melanoma, the most dangerous type, along with basal cell carcinoma and squamous cell carcinoma, which are known as non-melanoma skin cancers. It is important to check your skin regularly for any changes in moles or spots and see a doctor immediately if anything is noticed, as early detection can help avoid more serious outcomes from skin cancer like surgery or even death. Protection from the sun such as wearing sunscreen, protective clothing, hats, and seeking shade can help prevent skin cancer.
