Hi Shan Shan,
The most important step everyone can take to minimize their risk of skin cancer would be to take sun protection seriously. Wearing a hat, regular sunscreen, avoiding mid-day sun and never ever going under a sun bed would be a good start.
Routinely checking your own moles for any change and visiting a dermatologist every year for a skin check can also ensure that any abnormal skin changes can be picked up early.
