Be seen today
Arrange a prompt medical assessment for a lump that is growing, firm, painless, or not improving, especially if it occurs with persistent fever, night sweats, weight loss, unusual tiredness, abdominal swelling, or ongoing breathing symptoms.
A fever during chemotherapy can be urgent because the body's infection-fighting cells may be low.
Do not wait for other symptoms or give fever-reducing medicine to delay contacting the treatment team.
For less urgent concerns during treatment, contact the child's cancer team.
New symptoms, medicine problems, poor fluid intake, repeated vomiting, or changes in behavior may still need same-day advice.
The article also says
Children receiving treatment should follow the cancer team's instructions about fever and infection.
