Early recognition of unusual symptoms in children can lead to timely diagnosis and improved treatment outcomes.
Childhood cancer, though relatively rare, remains a growing global health concern. Nearly half of pediatric cancer cases occur in children aged 0-5 years. With advancements in technology and early diagnosis, treatment success rates have significantly increased. Memorial Şişli Hospital’s Pediatric Hematology-Oncology Expert, Prof. Dr. Atila Tanyeli, shares essential information on the warning signs of childhood cancer as World Cancer Day approaches.
Distinct Nature of Childhood Cancers
Pediatric cancers differ clinically, biologically, and genetically from adult cancers, making diagnosis more challenging. Early detection is critical, as prompt treatment greatly enhances the chance of a successful outcome. The most common types of childhood cancers include leukemia, brain and spinal cord tumors, lymphomas, soft tissue tumors, kidney tumors, and bone tumors.
Key Warning Signs to Watch For
Even though some symptoms can overlap with more common childhood illnesses, they warrant serious evaluation if they persist. Prof. Dr. Tanyeli emphasizes that awareness of these 15 warning signs could save lives:
- Unexplained bruising on the skin, particularly on the torso or upper legs, without any trauma.
- Excessive gum growth (gingival hypertrophy) or recurrent nosebleeds.
- Prolonged fever without an identifiable cause.
- Involuntary weight loss exceeding 10% of body weight over the past six months.
- Repeated morning vomiting, especially when not accompanied by nausea or headache.
- The appearance of lumps or swellings on the neck, body, or abdomen, particularly if they exceed 2 centimeters in size.
- Persistent bone, joint, back, or leg pain that worsens at night, accompanied by an unexplained limp.
- Unexplained prolonged fatigue, weakness, or a general sense of lethargy.
- An unusual whiteness in the eyes of infants (often noticed in flash photography), which should be investigated.
- Severe night sweats that soak clothing and are accompanied by other symptoms.
- Abdominal swelling with difficulty passing urine or stool, or blood in the urine, especially if there is a noticeable firmness in the abdomen.
- Facial paralysis or problems with walking.
- Persistent anemia that does not respond to iron supplements.
- Recurring or long-lasting infections that are difficult to treat.
- Behavioral changes in young children such as constant crying, excessive sleep, refusal to eat, or noticeable irritability.
Variations by Cancer Type
Different types of childhood cancers can present with additional or varying symptoms. For example, brain tumors may lead to headaches and balance issues, while leukemia might manifest as persistent weakness, anemia, frequent infections, and easy bruising without any injury.
Modern Treatments Improve Outcomes
Diagnosing and treating pediatric cancers requires specialized expertise. Diagnostic methods may include blood tests, imaging techniques (MRI, CT scans), bone marrow biopsies, and other advanced procedures. Treatment options range from surgery, chemotherapy, and radiation therapy to targeted drug therapies. Due to medical advancements, the overall success rate for treating childhood cancers has improved dramatically from below 50% in the 1960s to over 80% today. Acute lymphoblastic leukemia (ALL), especially of the B-cell type, now shows recovery rates reaching up to 90%. Although challenges remain for certain bone tumors, acute myeloid leukemia (AML), and neuroblastoma, early diagnosis coupled with appropriate treatment—including immunotherapy and, in selected cases, stem cell transplantation—offers renewed hope for many patients.
Preventive Measures and Risk Reduction
While it is impossible to eliminate the risk of childhood cancer entirely, several preventive measures may help reduce the risk:
- Ensure adequate folic acid intake during pregnancy.
- Breastfeed the infant for as long as possible.
- Provide children with ample opportunities for physical activity.
- Foster secure, nurturing environments to minimize negative childhood experiences.
- Avoid alcohol, tobacco, and unnecessary exposure to radiation during pregnancy.
- Keep children away from secondhand smoke and polluted air.
- Promote a balanced diet rich in fruits, vegetables, and whole grains.
- Limit exposure to chemicals known to be carcinogenic.
- Be cautious of prolonged exposure to electromagnetic fields, as emerging studies suggest potential cancer risks.
Conclusion
Awareness of these warning signs and preventive strategies is essential for safeguarding children’s health. Early detection through vigilant observation and regular pediatric check-ups can drastically improve treatment outcomes. As Prof. Dr. Atila Tanyeli notes, recognizing these symptoms early and acting promptly may be life-saving. Parents and caregivers are encouraged to consult healthcare professionals if any of these signs are observed, ensuring that children receive the best possible care and a chance for a healthier future.
