New DNA Test Determines Risk of Cancer

The video discusses the role of genetic differences in cancer risk, highlighting 83 DNA changes that influence the likelihood of developing breast, ovarian, or prostate cancer. It introduces DNA chip technology for screening genetic variations, potentially available in GP surgeries. The video also covers the impact of genetic testing on risk assessment, personal stories of individuals making informed choices, and the interplay of genetics and lifestyle in cancer risk. Ethical dilemmas regarding genetic information disclosure are also explored.

What is the significance of the 83 DNA changes discovered by researchers?

• They are unrelated to cancer risk.

• They only affect lung cancer risk.

• They can change how cancer is diagnosed and treated.

• They are only relevant to genetic disorders.

How might DNA chip technology be used in general practice?

• To replace all current cancer treatments.

• To increase the cost of cancer testing.

• To screen for 200,000 genetic variations in patients.

• To eliminate the need for any cancer screenings.

What was Wendy Watson's response to her genetic risk of cancer?

• She decided to wait for symptoms to appear.

• She chose not to inform her daughter.

• She and her daughter had preventive surgeries.

• She ignored the risk and continued with her life.

What percentage of cancer risk is determined by our DNA, according to the transcript?

• 10%

• 100%

• 30%

• 57%

What ethical dilemma does the research on genetic factors and cancer risk present?

• Whether to ignore genetic factors in cancer treatment.

• Whether to stop all cancer research.

• Whether to inform patients about genetic risks they cannot change.

• Whether to make genetic testing mandatory for everyone.
