I was diagnosed with skin cancer after noticing a freckle on my cheek. At first I didn't think anything of it, but over time I noticed the freckle starting to darken and change shape, so I went to my doctor. She referred me to a specialist for tests, which showed that I had melanoma, a serious form of skin cancer.
A plastic surgeon removed the freckle shortly after my diagnosis. My story is the perfect example of why you should report any unusual changes to your skin to your doctor as soon as possible. Early diagnosis not only means that treatment is less invasive, it could also save your life.
It's very important to see your doctor if you notice any unusual or persistent changes to your skin. You doctor will want to see you, and you're not wasting anyone’s time by getting checked out.
At your appointment, your GP will look at your skin and ask you what changes you have noticed. Your doctor may also ask about your personal and family history and about your exposure to the sun — whether you’ve had peeling sunburns or frequent exposure to ultraviolet radiation, such as from tanning beds.
If your doctor suspects cancer, you’ll be referred to a specialist for diagnosis and treatment.

Sunbeds and sunlamps can increase your risk of developing skin cancer. Public Health England recommends that you don't use them, except for medical reasons.
A healthy lifestyle can help you reduce your risk of skin cancer. Some ways to stay healthy are:
