Received call. They asked by name offering genetic testing for cancer by mouth swab. Asked for and given Medicare number. Told I qualify for free testing through Medicare. Swab will be received in 1 week, someone will call to review how to complete testing. Caller had my address and asked me to confirm it, asked for name and phone # of primary care doctor. Gave me the name and # of company with her extension to call with any questions. Just had a bad feeling.
