Skin cancer (melanoma) 


Living with cancer

Information on living with cancer, including treatment, support and different personal experiences of cancer

Melanoma is a rare and serious type of cancer that begins in the skin and can spread to other organs in the body.

The most common sign of melanoma is the appearance of a new mole or a change in an existing mole. This can happen anywhere on the body, but the back, legs, arms and face are most commonly affected.

In most cases, melanomas have an irregular shape and more than one colour. They may also be larger than normal moles and can sometimes be itchy or bleed.

An "ABCDE checklist" has been developed for people to tell the difference between a normal mole and a melanoma. Watch a visual guide to moles.

Why does melanoma happen?

Melanoma happens when some cells in the skin begin to develop abnormally. It is thought that exposure to ultraviolet (UV) light from natural or artificial sources may be partly responsible.

Certain things can increase your chances of developing melanoma, such as having:

  • lots of moles or freckles
  • pale skin that burns easily
  • red or blonde hair
  • a family member who has had melanoma

Diagnosing melanoma

See your GP if you notice any change to your moles. Your GP will refer you to a specialist clinic or hospital if they think you have melanoma.

In most cases, a suspicious mole will be surgically removed and studied to see if it is cancerous. This is known as a biopsy.

You may also have a test to check if melanoma has spread elsewhere in your body. This is known as a sentinel node biopsy.

How is melanoma treated?

The main treatment for melanoma is surgery, although your treatment will depend on your circumstances.

If melanoma is diagnosed and treated at an early stage, surgery is usually successful.

If melanoma isn't diagnosed until an advanced stage, treatment is mainly used to slow the spread of the cancer and reduce symptoms. This usually involves medicines, such as chemotherapy.

Once you have had melanoma, there is a chance it may return. This risk is increased if your cancer was widespread and severe.

If your cancer team feels there is a significant risk of your melanoma returning, you will probably need regular check-ups to monitor your health. You will also be taught how to examine your skin and lymph nodes to help detect melanoma if it returns.

Who is affected

Melanoma is relatively rare, but is becoming more common. There are currently around 13,000 new cases diagnosed each year in the UK.

Melanoma is one of the most common cancers in people aged 15-34 and more than a third of cases occur in people under 55. More than 2,000 people die every year in the UK from melanoma.

Can melanoma be prevented?

Melanoma is not always preventable, but you can reduce your chances of developing it by limiting your exposure to UV light.

You can help protect yourself from sun damage by using sunscreen and dressing sensibly in the sun. Sunbeds and sunlamps should also be avoided.

Regularly checking your moles and freckles can help lead to an early diagnosis and increase your chances of successful treatment.

I was diagnosed with a malignant melanoma in April 2012 at the age of 39. After a wide excision and the removal of a lymph node I was given the OK by the August 2012. I have my regular check ups every 3 months. Gave up smoking, got fit, eat healthily. Yet I am so paranoid about every ailment. How do I stop that?

I feel like I am going crazy. So far I have gone back to the doctor several times with little things that I was convinced were cancerous! And of course they were not. I have now got to the stage where I am trying to ignore things that are wrong with me because I do not want to waste my GP's time.

I find myself self diagnosing over the internet and getting myself in a bit of a state because of what you can read.

Do you have any advice?
