mole changes imaging results waiting

Overview

This article explains what it means when a mole changes and your healthcare provider asks for imaging (pictures of the inside of your body). It also covers how to cope while waiting for results.

Yes. Many people have moles, and it is common for some moles to change over time. Referral for imaging happens regularly when a mole looks unusual.

Anyone can have a changing mole, but people with fair skin, a history of sunburn, or many moles are more likely to be checked.

Symptoms

Common symptoms

• A mole that changes in size, shape, or color
• A mole that becomes asymmetrical (one half does not match the other)
• A mole with irregular, notched, or blurred borders
• A mole with multiple colors or uneven color
• A mole larger than a pencil eraser (about 6 mm)
• A mole that itches, bleeds, or crusts

Symptoms in children

• In children, moles can change naturally as they grow. However, any mole that grows much faster than the child, changes color unpredictably, or bleeds without reason should be checked.

Symptoms in older adults

• In older adults, new moles appear less often, so a new or changing mole may be more concerning. Age spots can also look like moles, but imaging can help tell the difference.

Causes

Main causes

• Moles change for many reasons, including hormone shifts, sun exposure, or simply aging.
• Sometimes a mole needs imaging because it looks different from others (the 'ugly duckling' sign).
• Imaging is also used to check whether a mole has grown downward into the skin, which could be a sign of melanoma.

Risk factors

• Frequent or severe sunburns, especially in childhood
• Having many moles (more than 50) or atypical moles (dysplastic nevi)
• Light skin, red or blonde hair, or blue eyes
• A family history of melanoma or other skin cancers
• A weakened immune system

When to see a doctor

See a doctor urgently if:

• A mole that changes rapidly, grows, or starts bleeding without any injury
• A new mole that appears after age 30
• A mole that looks very different from your other moles

Book a routine appointment if:

• Any ongoing change in a mole that has been present for a while, even if it is slow
• A mole that is tender, itchy, or sore for more than a few weeks
• A mole you are simply worried about – it is always worth asking

Diagnosis

To diagnose a mole, your healthcare provider will first look at it with a special magnifying tool called a dermatoscope. If they still have concerns, they may take a picture or use imaging to see beneath the surface and plan any further steps.

Tests that may be done

• Dermoscopy: a handheld microscope to examine the mole's patterns
• Total body photography: taking pictures of all your moles to track changes over time
• Ultrasound: uses sound waves to see if a mole is only on the surface or has grown deeper
• CT, MRI, or PET scans: only if there is a strong suspicion that a mole might be melanoma and it may have spread

What to expect at your appointment

Imaging is usually painless and quick. You may need to lie still for a few minutes. If a scan involves a dye (contrast), you might feel a warm sensation or a metallic taste, which is normal. Afterward, you can go home. The results may take several days to a few weeks. Your doctor will explain the results and next steps clearly.

Treatment

The treatment for a changing mole depends entirely on what the test results show. If a mole is benign, you may not need any treatment. If it is abnormal or cancerous, treatment usually starts with removing the mole and, if needed, a small margin of surrounding skin.

Self-care at home

• While waiting for results, keep the area clean and dry.
• Do not scratch or pick at the mole.
• Take a photo with a ruler beside it to track any changes yourself.

Medical treatments

Depending on the diagnosis, treatment approaches may include surgical removal of the mole (excision), a skin biopsy, or deeper surgery to remove any affected tissue. If cancer is found, your doctor may recommend additional treatments such as immunotherapy, targeted therapy, chemotherapy, or radiation therapy – all depending on the specific type and stage.

When is surgery considered?

Surgery is the most common treatment for a mole that turns out to be skin cancer. It is usually done under local anaesthetic, which numbs the area. You will be awake but feel no pain.

Living with this condition

During the waiting period, try to keep your normal routine. It is okay to check your mole gently, but avoid constant checking. Set aside a specific time each day if you feel anxious, then carry on with your day.

Lifestyle tips

• Protect your skin from the sun with clothing, shade, and sunscreen.
• Do regular self-exams of your skin once a month.
• Keep all follow-up appointments with your skin specialist.

Diet and exercise

A balanced diet and regular movement are always healthy. They can also help you feel more in control while you wait. No special diet is needed for a mole diagnosis.

Mental health and emotional wellbeing

Waiting for results can cause anxiety, sleeplessness, or low mood. These feelings are normal. If they become overwhelming, talk to your GP or doctor about support options.

Prevention

Not all moles can be prevented, but sun protection can lower your risk of developing new moles and of existing moles becoming abnormal. Avoid tanning beds and seek shade during peak sun hours.

Vaccines

There is no vaccine for mole changes or skin cancer. But research is ongoing.

Screening programmes

Screening includes regular skin self-exams. If you have many moles or a family history, your healthcare provider may recommend an annual full-body skin check by a dermatologist.

Complications

If left untreated

• A small percentage of changing moles may grow deeper into the skin over time, increasing the risk of melanoma.
• Delaying treatment for a melanoma can allow it to spread to lymph nodes or other organs, making it harder to treat.

Long-term outlook

The outlook for most changing moles is very good. Most turn out to be benign. Even if cancer is found, early detection and modern treatments mean that many people are successfully treated and go on to live healthy lives.
