Lung cancer survivorship in children

Overview

Lung cancer survivorship in children means looking after a child who has had cancer that started in the lungs and who has finished treatment. Survivorship care focuses on staying healthy, watching for any long-term effects of treatment, and supporting the child's emotional and mental wellbeing.

No, lung cancer in children is very rare. Most cancers in children are different types, such as leukemia or brain tumors. When a child is diagnosed with lung cancer, they are usually treated at a specialized children's cancer center.

Lung cancer can affect children of any age, from babies to teenagers. It may be slightly more likely in children who have certain genetic conditions or who were treated with chest radiation for a previous cancer.

Symptoms

Common symptoms

• A cough that doesn't go away
• Coughing up blood (even a small amount)
• Chest pain that is constant or gets worse
• Shortness of breath or wheezing
• Unexplained weight loss
• Feeling very tired all the time

Symptoms in children

• A persistent cough that might be mistaken for a cold or asthma
• Frequent chest infections that don't seem to clear
• Tiredness and low energy
• Swelling in the face or neck
• Feeding difficulties or poor appetite in infants

Symptoms in older adults

• Hoarseness (voice changes)
• Bone pain
• Headache
• Droopy eyelid or small pupil
• Difficulty swallowing

Causes

Main causes

• In most cases, the exact cause is unknown
• Changes (mutations) in lung cells that cause them to grow out of control
• Inherited genetic conditions, but this is very rare

Risk factors

• Previous radiation therapy to the chest for another childhood cancer
• Certain rare inherited syndromes (for example, Li-Fraumeni syndrome)
• Being around secondhand tobacco smoke for a long time
• Very rare environmental exposures (such as high levels of radon)

When to see a doctor

See a doctor urgently if:

• Call your child's care team right away if they have new coughing up of blood, trouble breathing, or worsening chest pain
• Seek immediate care if your child has a fever and is having difficulty breathing

Book a routine appointment if:

• Attend all scheduled follow-up appointments with the oncologist (cancer doctor)
• Report any new or changing symptoms, even small ones, at your regular visits

Diagnosis

To diagnose lung cancer in a child, the doctor takes a full medical history and examines the child carefully. Then they use imaging tests to look at the lungs and take a small tissue sample (biopsy) to confirm the diagnosis.

Tests that may be done

• CT scan (a special X-ray that creates detailed pictures of the lungs)
• MRI scan (uses magnets and radio waves to build images)
• Biopsy (taking a tiny piece of tissue to be examined under a microscope)
• Blood tests (to check general health and look for signs of cancer)
• Pulmonary function tests (to measure how well the lungs work)

What to expect at your appointment

If your child may have lung cancer, the care team will explain each test beforehand. The process can take a few weeks. You will be assigned a dedicated healthcare professional who will guide you through every step. You can ask questions at any time, and you should feel comfortable asking for written information.

Treatment

Treatment for childhood lung cancer depends on the type of cancer, its size, and whether it has spread. The plan is made by a team of pediatric cancer specialists who work together to give the best care for your child.

Self-care at home

• Provide a healthy diet to help the body recover
• Encourage rest and quiet time as needed
• Keep a simple daily routine to reduce stress
• Talk openly with the care team about any side effects or worries

Medical treatments

Treatment may include surgery to remove the tumor, chemotherapy (use of strong medicines to kill cancer cells), radiation therapy (high-energy beams that destroy cancer cells), and sometimes targeted therapies that attack specific changes in the tumor cells. The exact combination is personalized for each child. Your child's care team will explain what they recommend and why.

When is surgery considered?

Surgery is often used when the tumor is in one part of the lung and can be completely removed. The surgeon will discuss the operation, possible risks, and what recovery will look like. In some cases, a small piece of lung may be removed; in other cases, a lobe or the whole lung may need to be taken out.

Living with this condition

After treatment, your child may need extra rest and help with daily activities. Over time, most children return to school and normal routines. Regular follow-up appointments and scans are part of life after cancer. You may notice a new appreciation for small moments and a stronger bond with your child.

Lifestyle tips

• Keep the home completely smoke-free
• Avoid secondhand smoke and other lung irritants
• Encourage gentle physical activity after checking with the doctor
• Protect sun-exposed skin if your child had radiation therapy
• Stay up to date with vaccinations recommended by your doctor

Diet and exercise

Aim for balanced meals with vegetables, fruits, whole grains, and protein. Keep your child hydrated. Exercise should be fun and safe, such as walking, swimming, or cycling, but always ask the oncologist about what level of activity is best. Build up slowly and let your child rest when they need to.

Mental health and emotional wellbeing

Surviving cancer brings a mix of relief and worry. Children may experience anxiety, sadness, or fear, and parents often feel stress too. It is completely normal. Before check-ups, you may feel 'scanxiety' – a strong worry about the tests. These feelings usually get better over time. Ask about counseling or psychologist support at your hospital.

Prevention

Most childhood lung cancers cannot be prevented because the cause is unknown. You can reduce some risks by keeping your home free of tobacco smoke and avoiding other lung irritants. If your child has a genetic condition that raises cancer risk, your doctor may suggest special monitoring, but this is not the same as prevention.

Vaccines

There is no vaccine that prevents lung cancer. However, ensuring your child receives recommended vaccinations, such as flu and COVID-19 vaccines, is important because they can prevent lung infections that might complicate their health.

Screening programmes

There is no routine screening test for lung cancer in children. Follow-up scans and check-ups after treatment are not 'screening' – they are part of survivorship care to detect any late effects early.

Complications

If left untreated

• The cancer could grow larger and spread to other parts of the body
• Breathing could become seriously difficult
• It could become harder to treat successfully

Long-term outlook

Most children treated for lung cancer today have a good chance of survival, and many live healthy lives well into adulthood. Some children may experience long-term effects from treatment, but these can often be managed with the right care. Your care team will give you honest and hopeful information about your child's specific situation.
