For patients with neuroblastoma, diagnosis is primarily through the symptoms, signs, detailed physical examinations, medical history inquiries, and most importantly, radiological data, which includes CT scans or MRI of the head. Definitive diagnosis requires surgical removal of the tumor. A small amount of tumor tissue is retained after excision and used for pathological examination to confirm the diagnosis. Neuroblastoma is categorized as an epithelial-like malignant tumor, indicative of a high degree of malignancy. In most cases, early in the disease, the tumor adheres to surrounding tissues, which greatly complicates complete surgical removal, and most patients have a poor prognosis.

Causes of Neuroblastoma

Neuroblastoma is a highly malignant tumor. In most cases, it is seen in neuroepithelial cells. Currently, there is no consensus on the specific causes of neuroblastoma. It is generally believed that congenital genetic factors, as well as mutations, gene deletions, and changes in tumor suppressor genes in patients, are greatly related. Acquired factors should not be ignored either, such as poor lifestyle and dietary habits. In most cases, the prognosis for neuroblastoma is poor, with patients having a short survival period. Most patients, even after undergoing surgical treatment, often experience poor outcomes and ultimately die from multi-organ dysfunction and failure.

How to avoid neuroblastoma

To avoid neuroblastoma, it is recommended to develop good living habits in daily life, including maintaining over 30 minutes of aerobic exercise each day to keep physically healthy. Additionally, it is advisable to consume more fruits rich in vitamin C, which contain abundant vitamins that can effectively serve as antioxidants. Keeping good sleep habits, going to bed early and waking up early, avoiding staying up late and long durations of using mobile phones or computers to minimize excessive exposure to electromagnetic radiation. In daily life, one should also learn self-protection, avoid contact with carcinogenic chemicals, and avoid excessive exposure to radioactive pollution. All these measures can effectively prevent the condition.

How to check for neuroblastoma?

For the examination of neuroblastoma, we generally recommend a neurological examination to help determine whether there are any clear positive signs, as well as to inquire about medical history and family history to judge if there are any cases of neuroblastoma among family members. Additionally, detailed laboratory tests, routine blood tests, routine urine tests, and biochemical tests, including tumor-related diagnostics, can help in making assessments. Of course, the most accurate and crucial examinations are CT or MRI scans of the head. If necessary, an enhanced MRI scan of the head can be conducted to further evaluate the location, nature, severity of the tumor, and its relationship with the surrounding neural and vascular tissues, which helps provide a basis for further surgical treatment.

Symptoms of neuroblastoma recurrence

For neuroblastoma, when the tumor recurs, the patient's original symptoms such as headaches, dizziness, nausea, and vomiting will reappear, occurring intermittently and worsening persistently. Most patients will experience significant increased intracranial pressure, and even frequent nausea and vomiting. Additionally, some neuroblastoma patients experience severe vertigo, especially when changing body positions, where the vertigo is particularly pronounced. For such patients, when the above symptoms and signs occur, they should go to a local hospital as soon as possible for a reassessment using cranial MRI to monitor changes in their condition.

Early symptoms of neuroblastoma

For patients with neuroblastoma, the early stages of the disease often manifest as mild headaches, dizziness, nausea, and vomiting. The symptoms are relatively mild and can be significantly alleviated by taking oral pain relief medications. Therefore, the condition often does not receive adequate attention, leading to missed diagnoses. As the tumor size increases, the original symptoms such as headaches and dizziness will significantly worsen. Some patients may even experience optic nerve atrophy, papilledema, reduced visual fields, and vision deficits. When such conditions occur, patients often undergo cranial CT or MRI scans to confirm the presence of neuroblastoma.
