Genetics and Cancer Risk Assessment

The video provides an overview of cancer and genetics, explaining how gene mutations can lead to cancer. It discusses hereditary cancer, emphasizing the importance of family history in assessing cancer risk. The video also covers genetic testing, its role in identifying cancer risk, and how to interpret test results. It highlights the significance of genetic counseling and the Genetic Non-Discrimination Act in protecting individuals from misuse of genetic information.

What are some factors that can increase the risk of developing cancer?

• Diet and exercise alone

• Aging, environment, lifestyle, and family history

• None of the above

• Only genetic factors

How do mutations in genes typically occur?

• They are caused by diet

• They occur randomly over a person's lifetime

• They are always inherited from parents

• They are only caused by environmental factors

What is the likelihood of passing a hereditary cancer mutation to children?

• 100%

• 75%

• 50%

• 25%

What indicates a moderate risk for hereditary cancer in a family?

• All family members are cancer-free

• Two family members with cancer diagnosed before age 50

• One family member with cancer after age 60

• No family members with cancer

What is the purpose of genetic testing in the context of cancer?

• To assess a person's fitness level

• To determine a person's diet

• To identify mutations in cancer-protecting genes

• To cure cancer

What does a negative result in genetic testing imply?

• A guarantee of hereditary cancer

• No mutations found in the genes tested

• Immediate need for treatment

• No risk of cancer

What is a variant of uncertain significance in genetic testing?

• A change in a gene with unknown impact on cancer risk

• A mutation that definitely causes cancer

• A gene that has no function

• A mutation that prevents cancer

What does the Genetic Non-Discrimination Act (GNA) protect against?

• Discrimination based on age

• Discrimination based on genetic test results

• Discrimination based on income

• Discrimination based on education level

What is the role of genetic counselors in cancer genetics?

• To help understand and manage cancer risk

• To conduct surgeries

• To prescribe medication

• To provide legal advice

Why is it important to stay in touch with genetics?

• Genetics never changes

• Genetics is irrelevant to cancer

• New information may become available

• It is not important
