screening for mole changes

Overview

Screening for mole changes means looking at your skin regularly to spot any new, changing, or unusual moles. It is a way to catch skin cancer early, when it is easier to treat.

Yes. Skin cancer is one of the most common types of cancer, and checking your moles is a simple way to stay aware of your skin health.

Anyone can be affected, but people with fair skin, many moles, a history of sunburn, or a family history of skin cancer are at higher risk.

Symptoms

Common symptoms

• A mole that changes in size, shape, or colour
• A mole that becomes asymmetrical or has irregular borders
• A mole that starts itching, bleeding, or crusting
• A new mole that appears in adulthood, especially after age 30
• A mole that looks different from your other moles (the 'ugly duckling' sign)

Symptoms in children

• New moles are common during childhood and usually harmless.
• Watch for moles that grow very fast, bleed, or look unusual.
• Children with many moles or a family history of melanoma should be checked by a doctor.

Symptoms in older adults

• Older adults may develop new moles or existing moles may change over time.
• Skin becomes thinner with age, so any new or changing spot needs attention.
• Older adults should have regular skin checks, especially if they had sun exposure earlier in life.

Causes

Main causes

• Damage from ultraviolet (UV) radiation, from the sun or sunbeds, is the main cause of mole changes and skin cancer.
• Genetics and family history also play a role.
• People with certain types of moles (such as atypical moles) are more likely to develop concerning changes.

Risk factors

• Fair skin, light eyes, and light hair
• Many moles (more than 50) or any unusual moles
• A history of sunburns, especially in childhood
• Frequent use of tanning beds or intense sun exposure
• A personal or family history of skin cancer
• A weakened immune system

When to see a doctor

See a doctor urgently if:

• See a doctor urgently if you notice a mole that is changing rapidly, bleeding, itching, or has an irregular shape or multiple colours.

Book a routine appointment if:

• Have a full-body skin exam every year if you are at high risk (for example, many moles or previous skin cancer).
• Check your own skin once a month and see a doctor if you notice anything new or changing.

Diagnosis

A doctor or dermatologist will examine your skin, now the mole looks with a special magnifying tool called a dermatoscope. If they think a mole is suspicious, they may recommend a biopsy (removing a small piece and testing it).

Tests that may be done

• Full-body skin examination
• Dermatoscopy (looking at the mole with a special handheld microscope)
• Biopsy (removing the mole or a small part of it for laboratory testing)

What to expect at your appointment

You will be asked to remove clothing down to your underwear, and the doctor will look at your skin from head to toe. They may take photos or measure moles. If a biopsy is needed, a local anaesthetic numbs the area, and the procedure feels like a quick pinch. The sample is sent to a lab, and results usually come back in a week or two.

Treatment

If a mole is found to be skin cancer or pre-cancerous, treatment is most effective when it is started early. The main goal is to remove the abnormal cells completely.

Self-care at home

• Keep the skin clean and dry after any procedure.
• Follow your doctor's advice for wound care if you have a biopsy or mole removal.
• Avoid sun exposure while the skin heals, and use sun protection.

Medical treatments

Treatment depends on the type and stage of skin cancer. It may include surgical removal of the mole and a border of healthy skin. Other approaches include topical treatments, radiation, or newer therapies that help the immune system fight cancer. Your doctor will discuss the best plan for you.

When is surgery considered?

Surgery is the most common treatment for a suspicious mole or early-stage melanoma. It involves removing the mole and a small margin of normal skin to make sure all abnormal cells are gone.

Living with this condition

After any treatment, keep up with regular mole checks. Protect your skin every day with sunscreen and clothing, and be mindful of any new changes.

Lifestyle tips

• Use a broad-spectrum sunscreen with SPF 30 or higher every day, even when cloudy.
• Wear hats, sunglasses, and protective clothing when outdoors.
• Avoid sunbeds and indoor tanning.
• Do a self-check of your skin once a month.

Diet and exercise

A balanced diet and regular exercise are good for overall health, but they do not directly prevent skin cancer. However, staying active and eating well can help you feel better during recovery and support your immune system.

Mental health and emotional wellbeing

Worrying about moles or a skin cancer diagnosis can be stressful. It is normal to feel anxious. If you feel overwhelmed, talk to a counsellor or your doctor. For immediate mental health support, contact your local crisis helpline.

Prevention

Many skin cancers can be prevented by protecting your skin from the sun and avoiding tanning beds. Not all skin cancers can be prevented, but early detection makes treatment much easier.

Screening programmes

Regular self-examinations of your skin are a simple way to detect changes early. People at high risk may benefit from annual skin exams by a dermatologist or trained healthcare professional.

Complications

If left untreated

• If a cancerous mole is not removed early, melanoma can spread to other parts of the body.
• Advanced skin cancer is much harder to treat and can be life-threatening.

Long-term outlook

When caught early, almost all skin cancers are highly treatable. The five-year survival rate for early-stage melanoma is over 99%. So regular checks and prompt action give you the best chance of a good recovery.
