Before Scott Thompson resigned as Yahoo Inc.'s chief executive last weekend, he reportedly told the company's board of directors and several other colleagues that he had been diagnosed with thyroid cancer.
He disclosed the information late last week amid the controversy over an apparent misrepresentation on his resume, the Wall Street Journal said, citing anonymous sources.
A Yahoo spokesman didn't immediately respond to a request for comment.
Thompson, 54, resigned Sunday after his claim of holding a computer science degree from Stonehill College was questioned by activist shareholder Daniel Loeb.
Yahoo said this month that Thompson did not have the degree that its inclusion in an EBay biography and recent Yahoo securities filings was "an inadvertent error."
