Our expert voices conversation on genetic testing for cancer.

Genetic testing used to be very expensive, and so was done infrequently and judiciously. But advances in DNA sequencing technology now let us evaluate hundreds of genes for a fraction of what it used to cost to sequence just one.

The American College of Medical Genetics and Genomics has identified a list of genes associated with preventable adult-onset cancer syndromes. Each of these conditions has well-established, evidence-based guidelines for creating surveillance and treatment plans that your physician can use to guide preventive management.

Bottom line: We've long known that 5-10% of cancers derive from DNA mutations we inherit. These cancers tend to occur at an earlier age and affect multiple organs. If we could look at everyone's DNA, we would know who is silently carrying one of these misspellings and take steps to prevent them from developing the disease.

Tropical Storm Zeta has killed at least two people and caused mass power outages after making landfall in Louisiana as a Category 2 hurricane Wednesday.

What's happening: After "battering southeastern Louisiana and southern Mississippi," Zeta weakened to a tropical storm over central Alabama early on Thursday, but it was still packing powerful winds and heavy rains, per the National Hurricane Center.

Taiwan reaches a record 200 days with no local coronavirus cases

Taiwan on Thursday marked no locally transmitted coronavirus cases for 200 days, as the island of 23 million people's total number of infections reported stands at 550 and the COVID-19 death toll at seven.

Why it matters: Nowhere else in the world has reached such a milestone. While COVID-19 cases surge across the U.S. and Europe, Taiwan's last locally transmitted case was on April 12. Experts credit tightly regulated travel, early border closure, "rigorous contact tracing, technology-enforced quarantine and universal mask wearing," along with the island state's previous experience with the SARS virus, per Bloomberg.
