Summary
Five percent of childhood cancers stem from hereditary cancer syndromes. Genetic counseling is crucial for families, addressing cancer risks, prenatal diagnosis, and early detection strategies.
Area of Science:
- Oncology
- Genetics
- Pediatrics
Context:
- Childhood cancers account for a small percentage of all cancer diagnoses.
- Hereditary cancer disposition syndromes are a recognized factor in pediatric oncology.
- Identifying these syndromes is critical for comprehensive patient and family care.
Purpose:
- To outline the significance of hereditary cancer disposition syndromes in childhood cancers.
- To provide criteria for considering these syndromes in clinical practice.
- To detail the essential components of genetic counseling for affected families.
Summary:
- Approximately 5% of childhood cancers are linked to known hereditary cancer disposition syndromes.
- Consideration of these syndromes is warranted when cancers are frequently hereditary, multiple related cancers occur within a family, or congenital malformations are present.
- Genetic counseling should encompass familial cancer risks, patient's risk of secondary cancers, prenatal diagnostic options, and the benefits of prophylactic measures and early screening.
Impact:
- Improved identification of hereditary cancer syndromes in children.
- Enhanced genetic counseling leading to better risk assessment and management for families.
- Potential for earlier cancer detection and prevention strategies in at-risk individuals.

02:59Cancer Prevention
Several factors can increase the risk of cancer in an individual. About 50% of cancer cases can be prevented by adopting a healthy lifestyle, regular exercise, eating healthy, and following a modest cancer prevention diet. Epidemiological studies have consistently shown that populations with vegetable and fruit-rich diets have reduced the incidence of cancer. On the other hand, populations who have a diet rich in animal fat, red meat, junk food, or high calories are predisposed to cancer.

02:21Cancers Originate from Somatic Mutations in a Single Cell
Cancer arises from mutations in the critical genes that allow healthy cells to escape cell cycle regulation and acquire the ability to proliferate indefinitely. Though originating from a single mutation event in one of the originator cells, cancer progresses when the mutant cell lines continue to gain more and more mutations, and finally, become malignant. For example, chronic myelogenous leukemia (CML) develops initially as a non-lethal increase in white blood cells, which progressively...

01:20The Retinoblastoma Gene
Tumor suppressor genes are normal genes that can slow down cell division, repair DNA mistakes, or program the cells for apoptosis in case of irreparable damage. Hence, they play an essential role in preventing the proliferation of damaged cells.
The first-ever tumor suppressor gene called Rb was identified in retinoblastoma - a rare eye tumor in children. In inherited forms of the disease, a child inherits one defective copy of the Rb gene, which predisposes them to retinoblastoma. However,...

02:12What is Cancer?
Cells and tissues must meticulously coordinate their activities for the normal functioning of the human body. Therefore, they exhibit socially responsible behavior - resting, growing, dividing, differentiating, or dying - for the organism’s benefit. Cancer arises when cells divide uncontrollably and invade other tissues or organs.
