The daytime talk show "The Doctors" said Harper will appear Monday to talk with Travis Stork, Lisa Masterson and Andrew Ordon, as well as her own team of doctors.
The 1970s sitcom star has been diagnosed with a rare brain cancer and told she has as little as three months to live. She said her husband briefly withheld the diagnosis from her because it was so dire.
Harper, now 73, played Rhoda Morgenstern on television's "The Mary Tyler Moore Show" and its spinoff, "Rhoda."
She is given the full hour of Monday's talk show, and is surprised by former co-stars Ed Asner and Cloris Leachman.
