Symptoms of melanoma
The most common symptoms of melanoma are:
- A mole that suddenly gets bigger or you find a new one on your skin.
- A mole that develops a ragged or uneven outline.
- A mole with a mixture of different shades of brown, black or other colours through it.
- A mole that is bigger than the blunt end of a pencil.
- A mole that looks red or inflamed around the edges.
- A mole that is bleeding, oozing or crusting.
- A mole that starts to feel different, for example, slightly itchy or painful.
If you have any of the above signs, get them checked out by your doctor as soon as possible. He or she will examine you and decide what to do. Melanoma has a very good chance of being cured if diagnosed and treated early.
When checking a mole, look for the ABCDE:
Skin changes aren’t necessarily cancer. But it’s important to go to the GP and get any unusual changes checked out. If melanoma is diagnosed and treated early there is a very good chance of a cure.
Can I be screened for melanoma?
Testing for melanoma when you have no symptoms is called screening. There is no national melanoma screening programme in Ireland at present. The best way to check for early signs of melanoma is to check your skin for changes every month. This can help you to learn the moles, freckles and other skin marks that are normal for you.

If you have a risk factor for melanoma, talk to your doctor about mole mapping and getting checked more often.
Visit your family doctor (GP) first. He or she will examine your skin carefully. They can then refer you to hospital for a biopsy. Some GPs may take a sample of the affected skin and have it tested. But many GPs prefer that a skin specialist (dermatologist) removes a suspected melanoma.
A biopsy means taking a sample of cells and looking at them under a microscope to see if there are cancer cells in the sample. Usually the entire mole is removed by a dermatologist or plastic surgeon and examined.
If melanoma is found early, you may not need any more treatment after the mole is removed. If more treatment is needed, your doctor will talk to you about your options. For example, more surgery or treatment with chemotherapy or other cancer drugs. We have information on these treatments for melanoma.
A dermatologist is a doctor who specialises in treating skin problems.
