Side effects explained for teachers
When a child in your class has cancer, understanding both the medical side effects and the social–emotional impact can help you respond with empathy and practical support. Treatment plans vary, but most children experience a combination of chemotherapy, radiation, surgery, or immunotherapy, each with its own side effects.
The most common physical side effect is fatigue. Children may tire easily, need rest breaks, or have less stamina.
Hair loss can affect self-esteem; be sensitive to teasing and consider classroom discussions about empathy and differences.
Weight changes due to steroids, nausea, or changes in appetite.
Nausea and vomiting especially during or after chemotherapy.
Because of low white blood cells, the child might need to avoid crowds or sick classmates due to an increased risk of infection.
Low platelet counts may cause bruising or easy bleeding.
Children and teenagers may experience pain or discomfort from treatments or procedures.
Neuropathy (tingling, weakness in hands/feet) could affect writing or mobility.
Children and teenagers on cancer treatment may have trouble with memory, concentration, or processing speed due to cognitive changes.
The most common emotional side effects of childhood cancer and its treatment:
Children could experience anxiety or fear about treatments, hospital visits, or missing school.
They feel isolated due to the absences from school or feeling ‘different’.
Steroids and stress can cause mood changes such as irritability or emotional ups and downs.
Children and especially teenagers may experience low body image, especially with hair loss, physical changes, disabilities or scars.
Friendship struggles due to peers who may not know how to act or may avoid the child out of fear or misunderstanding.
