Genetic Testing and Hereditary Cancer

The video discusses genetic testing for hereditary cancer, emphasizing its importance in identifying cancer risks for individuals and their families. It explains the role of genes and mutations in cancer development, differentiates between hereditary and sporadic cancer, and outlines the genetic testing process. The video also covers interpreting test results, confidentiality, and the support available to individuals undergoing testing.

What is the primary purpose of genetic testing for hereditary cancer?

• To diagnose existing cancer

• To find out family ancestry

• To identify potential cancer risks

• To determine blood type

Which of the following is NOT a red flag for hereditary cancer?

• Cancer diagnosed under age 50

• Multiple family members with the same cancer

• A family member with a rare cancer

• Having a family member with diabetes

What is a gene?

• A blood component

• A type of protein

• An instruction manual for the body

• A type of cell

What percentage of cancers are considered hereditary?

• 5-10%

• 90-95%

• 50-60%

• 20-30%

What does a positive genetic test result indicate?

• No mutations found

• The person is immune to cancer

• The test was inconclusive

• A mutation was found in a cancer-protecting gene

What does a 'variant of unknown significance' mean in genetic testing?

• A mutation that is definitely harmful

• A mutation that is definitely harmless

• A mutation with unclear implications

• No mutation was found

What is the role of the genetic information non-discrimination act (GINA)?

• To ensure genetic test results are used for employment decisions

• To prevent genetic test results from being used against individuals

• To allow insurance companies to access genetic test results

• To mandate genetic testing for all individuals

What is the first step in the genetic testing process?

• Blood draw

• Consulting with a doctor

• Filling out a health history questionnaire

• Receiving test results

Why is it important to determine which side of the family a mutation was inherited from?

• To decide which family members to invite for testing

• To assess which family members might also be at risk

• To find out the mutation's origin country

• To determine the exact age of the mutation

What is the ultimate goal of genetic testing in cancer prevention?

• To replace traditional cancer treatments

• To ensure everyone gets tested

• To detect cancer as early as possible

• To eliminate all types of cancer
