Melanoma after treatment in children

Overview

Melanoma is a type of skin cancer that starts in the cells that give skin its color. When this article talks about melanoma after treatment in children, it means a child who has already been treated for melanoma either has a new melanoma in the same area or develops a different one. This is rare, but it is why children who have had melanoma need careful skin checks and follow-up care.

No. Melanoma is uncommon in children, and a second melanoma after treatment is even less common. However, children who have had melanoma do have a higher risk than other children, so doctors recommend careful monitoring.

It affects children who have been treated for a previous melanoma. It is more likely in children with fair skin, a family history of melanoma, many moles, or a history of sunburns during childhood.

Symptoms

Common symptoms

• A new spot that looks different from other spots on the skin.
• A mole that changes in size, shape, or color.
• An irregular border on a spot, like the edge is ragged or notched.
• A spot that is more than one color, such as brown, black, red, white, or blue.
• A sore that bleeds, itches, or does not heal.

Symptoms in children

• Melanoma in children can look like a bump, a pink or red growth, or a bleeding mole.
• It may be mistaken for a wart or a pimple that does not go away.
• Symptoms are similar to adults, but children often find it on areas less exposed to the sun, like the trunk or legs.

Symptoms in older adults

• In older adults, melanoma is more common on the face, ears, and scalp, especially after years of sun exposure.
• It may appear as a dark, changing mole or a persistent spot that has unusual edges.

Causes

Main causes

• Damage to skin cells from ultraviolet (UV) radiation, which comes from the sun or tanning beds.
• Changes in the DNA of skin cells that make them grow out of control, sometimes inherited.
• A weakened immune system, which can make it harder for the body to fight abnormal skin cells.

Risk factors

• Fair skin, light hair, and light eyes.
• Many moles, especially unusual or large moles.
• A family history of melanoma.
• Previous melanoma, including after treatment.
• History of sunburns, especially during childhood.

When to see a doctor

See a doctor urgently if:

• If your child has any new or changing mole or spot that is growing, changing shape, or itching, see a doctor that week.
• If a spot bleeds without being scratched, or does not heal within three weeks, see a doctor soon.
• If you notice a mole with an irregular border or multiple colors, make an appointment with a skin specialist.

Book a routine appointment if:

• Follow the follow-up schedule recommended by your child's cancer team.
• Have a full skin exam by a dermatologist at least once a year, or more often if your doctor advises.
• Do a monthly skin check at home and tell the doctor about any new spots that look different.

Diagnosis

A doctor looks at the spot closely and may use a special magnifying tool called a dermatoscope. If the spot looks suspicious, the doctor will remove a small piece to examine it under a microscope. This is called a biopsy. You do not need to guess if it is melanoma; the biopsy will give a clear answer.

Tests that may be done

• Skin biopsy: removing a small sample of the spot to look for cancer cells.
• Lymph node examination or a sentinel lymph node biopsy if the melanoma is deep, to see if it spread.
• Imaging scans, such as ultrasound, CT, or MRI, only if the doctor suspects the cancer has spread.

What to expect at your appointment

A biopsy is usually done in a clinic with a local anesthetic, so your child's skin goes numb and does not hurt. It takes only a few minutes. The sample is sent to a lab, and results take about one to two weeks. The doctor will call to explain what they found and the next steps.

Treatment

Treatment depends on how deep the melanoma is and whether it has spread. The main treatment is surgery to remove the melanoma and a small margin of healthy skin around it. If the melanoma is thicker, doctors may check nearby lymph nodes. Some children need additional treatments after surgery to reduce the chance of it coming back.

Self-care at home

• Protect the skin from the sun every day.
• Do regular skin checks at home and bring any changes to your doctor's attention.
• Keep all follow-up appointments with the cancer team and dermatologist.
• Encourage your child to be active and eat healthy foods, but avoid too much time in the sun.

Medical treatments

Medical treatments, besides surgery, may include medicines that help the body's immune system fight cancer cells, or treatments that target specific changes in the cancer cells. Sometimes radiation therapy is used if the melanoma is in a place that is hard to remove safely, or if there is a higher chance of returning. Doctors choose the best approach for each child. Ask your child's care team to explain the options in more detail.

When is surgery considered?

Surgery is usually the first treatment. The doctor removes the melanoma plus a narrow rim of normal-looking skin around it. This is done under anesthesia, and most children go home the same day. Later, if tests show cancer cells in lymph nodes, another surgery may be needed.

Living with this condition

After treatment, your child can live a normal life. The main changes are sun safety and regular skin checks. Use sunscreen, wear a hat, and try to stay in the shade when the sun is strong. Your child can still play outside, just with protection.

Lifestyle tips

• Use a broad-spectrum sunscreen with SPF 30 or higher and reapply every two hours.
• Wear protective clothing, a wide-brimmed hat, and sunglasses when outdoors.
• Avoid indoor tanning beds completely.
• Check your child's skin once a month from head to toe, including palms, soles, and under nails.

Diet and exercise

A healthy diet with plenty of fruits, vegetables, and whole grains can support your child's overall health. Regular physical activity helps with mood and energy. No special diet is needed for melanoma, but a balanced lifestyle is good for recovery.

Mental health and emotional wellbeing

Having had melanoma can be scary. Children may worry about the cancer coming back, or feel different from friends. These feelings are normal. Talk with your child openly, and let them know you are there to listen. Some families find it helpful to meet with a counselor or child psychologist. This does not mean you are not coping; it just gives your child extra support.

Prevention

Not all melanomas can be prevented, but you can lower the risk of a new one by protecting the skin from UV rays, avoiding sunburns, and not using tanning beds. Early detection is also important, which is why regular skin checks are so valuable.

Vaccines

There is currently no vaccine to prevent melanoma. Some vaccines are being studied in clinical trials, but they are not available for general use. Talk to your doctor if you are interested in research studies.

Screening programmes

After treatment, most children are offered a skin screening program. This means a dermatologist checks the whole skin at regular intervals, such as every six to twelve months. Screening helps catch any new melanoma early, when it is easier to treat.

Complications

If left untreated

• The melanoma can grow deeper into the skin.
• It can spread to lymph nodes or other organs, such as the liver, lungs, or brain.
• If it spreads, it becomes harder to treat and can be life-threatening.

Long-term outlook

Most children with melanoma are diagnosed early because caregivers take changes seriously. When melanoma is caught early, treatment is very effective and the outlook is excellent. Even if the melanoma is thicker, many children remain well after treatment. Medical care continues to improve, and there is every reason to be hopeful.
