Lymphoma survivorship overview in infants
Informed by recognized medical guidance
Overview
Lymphoma is a cancer of the lymphatic system, which is part of the immune system. When it happens in a baby under one year old, it is called infant lymphoma. Survivorship is the time after treatment ends. This overview explains what to expect during survivorship and how to help your baby grow and develop well.
Key facts
- Infant lymphoma is very rare, and many infants are cured with careful treatment.
- Survivorship care includes regular check-ups to spot any late effects early.
- A survivorship care plan is a written guide to your child’s follow-up care.
- Parents are a vital part of the care team.
No. Lymphoma in infants is extremely rare. Only a handful of infants are diagnosed each year. Because it is so rare, treatment and follow-up are usually done at specialist children's cancer centres.
Infant lymphoma affects babies under 12 months of age. It is slightly more common in boys. Survivorship affects the whole family — parents, siblings and caregivers all live with the experience.
Symptoms
- Trouble breathing or blue lips
- Seizures or stiff body movements
- Very difficult to wake or not responding
- Signs of an allergic reaction (swelling of face or throat)
- ⚠Fever that lasts more than 24 hours
- ⚠Vomiting and diarrhoea with signs of dehydration (few moist nappies)
- ⚠A new lump that gets bigger quickly
- ⚠Unusual bleeding or bruising
Common symptoms
- A painless lump or swelling in the neck, armpit or groin
- Unexplained fever that keeps coming back
- Night sweats and unusual tiredness
- Rapid breathing or a cough that doesn’t go away
Symptoms in children
- Older children may complain of pain, itching or fatigue
- Watch for weight loss or a change in appetite
- Swollen glands are often painless
Symptoms in older adults
- Adults who survived infant lymphoma are at risk for late effects like heart disease, second cancers and hormone problems.
- They need regular health checks with a primary care provider.
Causes
Main causes
- The exact cause is unknown in most cases.
- Some inherited immune disorders are linked to a higher risk.
- Epstein-Barr virus infection has been linked, but most infected babies do not get lymphoma.
Risk factors
- Being under 12 months of age
- Being male
- Having an immune disorder from birth
- Previous infection with Epstein-Barr virus
When to see a doctor
See a doctor urgently if:
- If your baby has trouble breathing
- If your baby is unusually sleepy or hard to wake
- If your baby is having fits (convulsions)
- If you notice sudden swelling of the face or neck
Book a routine appointment if:
- At each scheduled survivorship follow-up
- Whenever you are worried about a new symptom
- If your baby is not feeding or gaining weight as expected
Diagnosis
Lymphoma is diagnosed through a physical exam, blood tests, imaging scans and a biopsy. A biopsy removes a tiny piece of tissue from an enlarged lymph node or lump so it can be examined under a microscope.
Tests that may be done
- Physical exam of the lymph node areas, liver and spleen
- Blood tests, including a complete blood count and metabolic panel
- Imaging scans such as ultrasound, CT or MRI
- Biopsy of the affected tissue
What to expect at your appointment
During diagnosis, you will meet a team of specialists. After treatment, survivorship care takes over. You will get a care plan that explains the schedule of check-ups, tests, and who to contact if you have concerns.
Treatment
Treatment for infant lymphoma is designed to cure the cancer while protecting the baby’s growth and development. Babies with lymphoma usually receive treatment in a specialised paediatric oncology unit.
Self-care at home
- Wash hands often and limit visitors who are sick
- Keep the baby’s immunisations up to date as recommended by the care team
- Provide plenty of rest and gentle play
- Make sure the baby gets proper nutrition, whether from breast milk, formula, or specially prescribed feeds
Medical treatments
Treatment may include chemotherapy (medicines that kill cancer cells), targeted therapy (medicines that attack specific cancer cell features), radiation therapy (high-energy beams) or stem cell transplantation. The exact combination depends on the lymphoma type and the baby's overall health.
When is surgery considered?
Surgery is not usually a main treatment for lymphoma. It is used mainly to insert a central line, take a tissue sample (biopsy), or manage complications.
Living with this condition
When treatment ends, life returns to a new rhythm. Most infants go on to reach typical milestones, but they may need extra patience and support. Follow-up visits become less frequent over time, but they still matter.
Lifestyle tips
- Set a predictable daily schedule
- Encourage play, tummy time and cuddles
- Keep the home smoke-free
- Limit contact with people who have infections
Diet and exercise
In the first year, breast milk or formula gives your baby important nutrients. When solid foods are introduced, offer a variety of healthy foods. Gentle physical activity like tummy time helps build strength and coordination. Always ask your care team if you have concerns about physical limitations.
Mental health and emotional wellbeing
Parents and families may feel anxiety, sadness or guilt long after treatment ends. These feelings are common. Talking to a psychologist, joining a parent support group, or taking time for self-care can make a big difference.
Prevention
There is no known way to prevent infant lymphoma. But survivorship care can prevent or reduce late effects by monitoring your child’s health closely.
Vaccines
Immunisations are important for survivors. However, some live vaccines may not be safe until the immune system has recovered. Your specialist will advise a personalised vaccine schedule.
Screening programmes
Regular screening after treatment may include hearing tests, echocardiograms (heart ultrasound), kidney function tests, and developmental assessments. These help catch problems early.
Complications
If left untreated
- Untreated lymphoma can spread to the bone marrow, liver, lungs or brain
- It can cause serious infections because the immune system gets weaker
- It can block airways or blood flow, which can become life-threatening
Long-term outlook
The outlook for infant lymphoma has improved greatly in recent years. Many babies are cured and go on to live full, healthy lives. Long-term follow-up is key to managing any late effects and supporting your child’s development. Each child is different, so talk to your care team about what to expect for your family.
