How to Deal with Signs of Childhood Cancer

Childhood cancers are diagnosed at a rate of less than 2% of all cancer cases worldwide, i.e., about 170 cases per year per million children. Their early symptoms may appear as recurrent fever or pallor or persistent fatigue, symptoms that resemble many common childhood illnesses, which sometimes leads to delayed diagnosis.

The specialist doctors explain that the most common types differ from those seen in adults, and that a proportion of cases is linked to genetic, immunological, or environmental factors, while many causes remain unidentified. Conversely, they stress that survival rates are high, and early diagnosis and specialized treatment increase the chances of success.

This article presents the most common types, associated factors, warning signs that warrant a doctor's visit, the diagnostic pathway, recorded survival rates, based on what the specialist doctors explain.

The most common types

Leukemia (blood cancer) leads with about one-third of cases, followed by brain and nervous system tumors at around 20%, then lymphomas. There are also types that occur only in children, such as neuroblastoma and Wilms' tumor of the kidney.

What are the causes of the disease?

Some children are more susceptible due to genetic factors, such as Down syndrome, weakened immunity, or bone marrow deficiency. Environmental factors also play a role: what the mother is exposed to during pregnancy, the nature of the parents' work—such as working at fuel stations—certain viruses, agricultural pesticides, and radiation.

But the specialist doctors reject blaming the parents. The child's illness is like an "earthquake at home," which is enough to cause the family pain; there is no need for additional blame to be added.

Red flags: When to act?

Many of these symptoms resemble what any child experiences, and there is no need to panic if they persist for a day or two. However, if they recur or last longer, seeing a doctor becomes an immediate step:

• Recurrent or persistent fever, even if mild.

• Sudden pallor and unexplained fatigue.

• Bruises or bleeding without an obvious cause.

• Frequent infections.

• Abdominal swelling or swelling of neck glands.

• Night sweats, itching, weight loss and loss of appetite.

• Recurrent headache accompanied by vomiting or balance disturbances.

• Persistent bone pain, especially in the knee or back.

How is the diagnosis made?

Clinical examination remains the most important, followed by bone marrow tests, genetic tests, and MRI or PET Scan imaging. The step that ensures the best treatment is to present each case to the "oncology committee," which brings together various specialties, and this is mandatory in this pathway.

Do we tell the child?

Yes, in a manner appropriate to their age. The specialist doctors emphasize that children whose parents concealed the truth from them suffered more than others, especially teenagers who seek everything through screens. Trust is the foundation of treatment, and "half the battle is believing in success."

Real hope in numbers

Survival rates are very high: over 90% for leukemia, 95% for lymphomas, and over 80% for childhood cancers overall. Over the past decade, targeted and immunotherapy treatments have been introduced into pediatric care alongside surgery, chemotherapy, and radiotherapy, and their high cost makes the role of associations and ministries essential.

Psychological support is not a luxury

The specialist doctors stress that psychological follow-up is essential for the child and family, and is not a luxury. They achieve closeness to children in the hospital by being present as an older sibling, joking with them and singing to them, without the image of a "tough wise man" that scares them.

Final advice to the mother

Watch your child calmly, and be alert to any recurring or unusually prolonged symptoms. But do not let fear turn into a lens that interprets every minor sign as cancer: most what children experience does not mean they have cancer, yet if certain signs persist or multiple symptoms appear together, consulting a doctor to determine the cause is necessary.

Face anxiety with knowledge and medical follow-up, not with panic or neglect of signs, for early diagnosis and specialized follow-up open a wide door to treatment and hope. As the specialist doctors describe this situation, the disease may be an "earthquake at home," but the family does not stand helpless before it; they confront it step by step with medical and psychological support and belief in the possibility of success: "We will face it together."
