mole changes follow up care

Overview

A mole is a spot of skin growth that can be flat or raised. Follow-up care means keeping an eye on your moles over time — checking for changes, protecting your skin, and seeing a doctor if something looks different.

Yes. Most people have between 10 and 40 moles by adulthood. Checking them is a normal part of looking after your skin.

Anyone can develop moles, but people with fair skin, light hair, a high number of moles, or a family history of skin cancer may need to check more often.

Symptoms

Common symptoms

• Asymmetrical shape
• Irregular border
• Uneven colour
• Larger than a pencil eraser
• Changing over time
• Itching or bleeding

Symptoms in children

• New moles appearing during childhood is normal, but rapid changes or an unusual-looking spot should be checked.
• Bleeding, oozing, or a mole that grows quickly.

Symptoms in older adults

• New moles after age 50 are less common and should be examined.
• Moles in older adults may change shape or colour from sun damage.

Causes

Main causes

• The exact cause of moles is not fully understood. They form when pigment-producing cells grow in clusters.
• Sun exposure, especially intense or burning exposure, can affect how moles look and increase the chance of skin cancer.
• Genetics and family history play a role.

Risk factors

• Fair skin that burns easily
• A large number of moles (more than 50)
• A family history of melanoma
• Previous skin cancer
• History of sunburn, especially in childhood
• A weakened immune system

When to see a doctor

See a doctor urgently if:

• Any mole that changes in size, shape, or colour.
• A mole that starts to bleed, itch, or crust.
• A mole that looks completely different from your other spots.

Book a routine appointment if:

• A full skin check once a year if you have high-risk factors like many moles or a family history.
• A baseline skin check from a doctor as part of your general care.

Diagnosis

A doctor looks at your mole with a bright light and often a special magnifying lens called a dermatoscope. If needed, a small sample (biopsy) is taken to be examined under a microscope.

Tests that may be done

• Skin examination
• Dermatoscopy
• Biopsy (shave, punch, or excision)

What to expect at your appointment

The doctor will ask about changes, examine your skin, and may take photos. If they decide to biopsy the mole, a local anaesthetic numbs the area. The procedure takes minutes, and the wound heals quickly. Results usually come back within a week or two.

Treatment

Most moles require no treatment. Follow-up care simply means monitoring. If a mole is atypical or cancerous, treatment usually begins with surgical removal.

Self-care at home

• Perform a monthly mole self-check using a mirror.
• Photograph your moles so you can spot changes.
• Use a broad-spectrum sunscreen (SPF 30 or higher) and reapply every two hours.
• Wear protective clothing, hats, and sunglasses.

Medical treatments

If a mole is found to be precancerous or cancerous, the standard approach is to remove it surgically with a small border of healthy skin. In some cases, additional tests or treatment may be recommended, depending on the cell type and depth. Your doctor will explain the best plan for you.

When is surgery considered?

Surgery is recommended if a biopsy shows melanoma or an atypical mole. The surgeon removes the mole and a narrow margin of normal skin around it.

Living with this condition

Live with an awareness of your skin. Check your moles monthly, protect yourself when outdoors, and keep any follow-up appointments. Many people take photos to track changes.

Lifestyle tips

• Avoid tanning beds and sunburns.
• Use sunscreen even on cloudy days.
• Wear a wide-brimmed hat and long sleeves in strong sun.
• Add a mole check to your birthday or New Year routine.

Diet and exercise

There is no special diet for mole follow-up care. Eating a balanced diet rich in fruits and vegetables and staying physically active supports overall health, which may help your immune system.

Mental health and emotional wellbeing

Waiting for test results or worrying about skin cancer can cause anxiety. It is normal to feel concerned. If you are struggling, talk to your doctor, family, or a mental health professional. For immediate crisis support, contact your local mental health crisis service.

Prevention

You cannot always prevent moles, and most are harmless. You can reduce the risk of skin cancer by protecting your skin from ultraviolet (UV) radiation.

Vaccines

There is currently no vaccine against mole changes or skin cancer. Sun protection is the most effective preventive measure.

Screening programmes

Regular self-examination and clinical skin checks are recommended, especially if you have many moles or a strong family history. Ask your doctor how often you should be screened.

Complications

If left untreated

• A melanoma can grow deeper and spread to other parts of the body if left untreated.
• A bleeding or irritated mole can become infected.

Long-term outlook

The vast majority of moles are harmless. The earlier a melanoma is found, the more treatable it is. Routine monitoring gives you a great chance of catching problems early and handling them successfully.
