Guardant Health Inc., a Silicon Valley cancer detection firm, is considering an initial public offering in the U.S., people with knowledge of the matter said.

The company is in talks with advisers for a share sale that could take place as soon as the fourth quarter, said the people, who asked not to be identified because the information is private. Guardant hasn’t decided on the size of a potential offering, although a deal could raise as much as $500 million, the people said.
