Why do babies get tumors?
In recent years, the incidence of infant tumors has gradually attracted social attention. Many parents are confused and worried about the causes of tumors in their babies. This article will combine the hot topics and hot content on the Internet in the past 10 days, analyze the causes of infant tumors from a scientific perspective, and provide structured data to help readers better understand this issue.
1. Common types of infant tumors
The types of tumors in babies are different from those in adults. Here are some common ones:
| Tumor type | Proportion | High incidence age |
|---|---|---|
| Neuroblastoma | about 28% | 0-5 years old |
| nephroblastoma | about 20% | 1-4 years old |
| retinoblastoma | about 12% | 0-2 years old |
| hepatoblastoma | about 8% | 0-3 years old |
2. Main causes of infant tumors
1.genetic factors: About 5-10% of infant tumors are related to inherited gene mutations. For example, mutations in the RB1 gene can cause retinoblastoma.
2.environmental factors during pregnancy:
| risk factors | Types of tumors that may result | risk increase multiple |
|---|---|---|
| Ionizing radiation during pregnancy | Leukemia, brain tumors | 2-3 times |
| Smoking during pregnancy | hepatoblastoma | 1.5 times |
| certain drug exposure | Various tumors | 1.2-2 times |
3.congenital developmental abnormalities: Certain congenital diseases, such as Beckwith-Wiedemann syndrome, increase the risk of cancer by 40%.
4.viral infection: For example, Epstein-Barr virus may be related to some childhood lymphomas.
3. Recent hot research and discoveries
According to the scientific research trends in the past 10 days:
| research institute | Discover content | Publication time |
|---|---|---|
| Harvard Medical School | New infant tumor marker TRIM28 discovered | 2023.11.05 |
| Shanghai Children's Medical Center | Establishing a new program for early screening of infant tumors | 2023.11.08 |
| Cancer Research UK | Link between folic acid deficiency during pregnancy and infant tumors confirmed | 2023.11.10 |
4. Prevention and early detection
1.Pregnancy care: Avoid contact with harmful substances and supplement nutrients such as folic acid.
2.newborn screening: Some tumors can be detected early through B-ultrasound and other examinations.
3.Watch for symptoms:
| Symptoms | Possible tumors |
|---|---|
| Fever of unknown origin | Leukemia, lymphoma |
| abdominal mass | neuroblastoma, nephroblastoma |
| Abnormally reflective eyeballs | retinoblastoma |
5. Treatment progress and prognosis
Modern medicine has made significant progress in the treatment of infant tumors:
| Treatment | 5 year survival rate | Applicable tumor types |
|---|---|---|
| Surgery + chemotherapy | 60-90% | solid tumors |
| targeted therapy | 70-95% | specific gene mutation |
| Immunotherapy | 50-80% | hematological tumors |
Although infant tumors are worrisome, with advances in medicine, many types can be treated with good results. Parents should maintain scientific awareness, conduct regular physical examinations, and seek medical attention promptly if abnormalities are found.
This article synthesizes recent hot research and clinical data, hoping to help readers gain a more comprehensive understanding of infant tumors, an important health issue.
