Childhood cancer refers to cancers that occur in children and adolescents and often have no clear cause, though genetic mutations play a role in some cases. Early warning signs can include unexplained weight loss, persistent pain or swelling, frequent infections, unusual bruising or bleeding, chronic fatigue, relentless headaches, lumps, or vision changes that don’t improve. Recognising these symptoms early and seeking timely medical evaluation can lead to prompt diagnosis and effective treatment. With experienced care from Dr Nandini Hazarika, tailored support and modern therapies help improve outcomes and guide families through diagnosis, treatment and recovery for young patients.
