Melanoma after treatment patient overview
Informed by recognized medical guidance
Overview
Melanoma is a type of skin cancer that starts in the cells that give skin its color. After treatment, this overview explains what to expect during follow-up care and how to stay healthy.
Key facts
- Melanoma is generally treatable, especially when found early.
- After treatment, routine skin checks help detect any new or returning melanoma early.
- Follow-up care often involves a skin exam by a doctor every few months.
- You can take steps like sun protection to lower the risk of a new melanoma.
- Most people treated for melanoma do not have it come back, but it is important to stay alert.
Melanoma is the least common type of skin cancer, but it is also the most serious. It is more common in people with fair skin, a history of sunburn, or many moles. After treatment, follow-up care is a normal part of recovery.
Melanoma can affect anyone, but it is more common in adults, especially those over 50. It can also appear in younger adults and, rarely, children. After treatment, follow-up care is important for people of all ages.
Symptoms
- Call your local emergency number if you have severe headaches, seizures, trouble breathing, or sudden weakness — these may be signs the melanoma has spread and requires urgent medical care.
- ⚠See a doctor the same day if you have a new lump, swelling, or unusual pain near the treatment area.
- ⚠Seek same-day care if you have a sore that bleeds and does not stop.
Common symptoms
- A new dark spot or mole that looks different from your other moles.
- A sore that does not heal.
- A change in the size, shape, or color of an existing mole.
- Swelling or a lump under the skin near the treated area.
- New pain, numbness, or tingling in an area that was treated.
Symptoms in children
- Children may show the same signs as adults.
- Any new mole that changes or a spot that looks unusual should be checked by a doctor.
Symptoms in older adults
- Older adults may have thinner skin and more sun damage, so new spots or changes may be harder to see.
- Regular skin checks are particularly important.
Causes
Main causes
- Melanoma begins when the pigment-producing cells in the skin grow out of control.
- The main cause is damage from ultraviolet (UV) radiation, usually from the sun or tanning beds.
Risk factors
- Fair skin
- A history of sunburns
- Many moles
- A family history of melanoma
- A weakened immune system
- A personal history of melanoma
When to see a doctor
See a doctor urgently if:
- A new or changing spot that you have not shown your doctor yet.
- A sore that does not heal within a few weeks.
- A lump or swelling that appears suddenly.
Book a routine appointment if:
- Routine follow-up visits with your dermatologist, usually every 3 to 12 months depending on your risk.
- Report any new mole that appears, even if it looks normal.
Diagnosis
After treatment, your doctor will examine your skin and may feel your lymph nodes. If something looks suspicious, a small tissue sample (biopsy) may be taken and checked under a microscope.
Tests that may be done
- Skin exam by a doctor
- Lymph node ultrasound
- Blood tests
- Imaging scans, such as CT, MRI, or PET scans, if the doctor is concerned about spread
What to expect at your appointment
During a follow-up visit, your doctor will look at all your skin, including scars from treatment. You may be asked to check your own skin at home. Visits are usually quick and painless.
Treatment
Treatment for melanoma after the first treatment depends on whether it has come back or spread. Options may include surgery to remove any new melanoma, and other therapies to help the immune system fight the cancer. Your doctor will discuss the best plan for you.
Self-care at home
- Protect your skin from the sun every day, even on cloudy days.
- Use a broad-spectrum sunscreen and wear protective clothing.
- Check your skin at least once a month using a mirror.
- Keep a list of your moles and take photos to track changes.
- Stay active and maintain a healthy lifestyle to support your recovery.
Medical treatments
Medical treatments for melanoma that has returned or spread include immunotherapy, which helps your immune system attack the cancer; targeted therapy, which targets changes in the cancer cells; and chemotherapy, which uses medications to kill cancer cells. Radiation therapy may also be used. The exact treatment plan depends on your situation and will be explained by your healthcare team.
When is surgery considered?
Surgery is a common first step if the melanoma has come back in the skin or nearby lymph nodes. Your doctor will explain the type of surgery and what to expect.
Living with this condition
After treatment, life returns to a normal rhythm, but with added attention to your skin and health. You may have scars or changes in how your skin looks and feels. It's important to give yourself time to adjust.
Lifestyle tips
- Use sun protection every day, including sunscreen, hats, and sunglasses.
- Avoid tanning beds and sunburns.
- Do a monthly full-body skin check, and ask a family member to check your back and scalp.
- Attend all scheduled follow-up visits with your dermatologist.
Diet and exercise
There is no special diet that cures melanoma, but eating a balanced diet with plenty of fruits, vegetables, whole grains, and lean protein can help you feel strong. Regular exercise, like walking or swimming, can improve your energy and mood. Always check with your doctor before starting a new exercise program.
Mental health and emotional wellbeing
A melanoma diagnosis and treatment can bring feelings of anxiety, fear, or sadness. It is normal to feel worried about the future. This is very necessary to address. Consider talking to a mental health professional or joining a support group to share your feelings.
Prevention
You cannot change a past melanoma, but you can reduce the risk of a new melanoma by protecting your skin from UV exposure and watching for changes. Regular skin checks are essential.
Vaccines
There is currently no vaccine to prevent melanoma.
Screening programmes
If you have had melanoma, your doctor will recommend regular skin checks. You may also be advised to have imaging scans if your risk of spread is higher. Screening helps catch any recurrence early.
Complications
If left untreated
- If a recurrence is not treated, melanoma can spread to other parts of the body, such as the lymph nodes, lungs, liver, brain, or bones.
- This can cause serious health problems.
- This is why follow-up care is so important.
Long-term outlook
Many people treated for melanoma do very well. Recurrences, when caught early, can often be treated successfully. Outcomes have improved greatly with newer treatments. Your medical team will work with you to give you the best chance of a healthy future.
