Harper went on to tell Mario she is feeling well. "This course of treatment is working� each subsequent brain scan I get looks better and better. It's not curable yet, as my husband says, let's push the time limit� I'm past my expiration date and I plan to keep doing that if I can."

The actress explained to Mario that both her doctors and husband Tony Cacciotti encouraged her to participate in "DWTS." "He (Tony) wanted me to keep working when we got the diagnosis. He said, 'Valerie let's not accept it, you keep pushing, you keep active.'"

Valerie, who is dancing with Tristan MacManus, went on to say the disease is not affecting her dancing, "I'm not having any problems with my cancer, I'm having a problem with my left knee, they're 74 years old now and I haven't danced professionally in 50 years."

The "Mary Tyler Moore" alum promised Mario that they will dance together next year, "Thank you for your incredible vote of confidence that it would be a year from now, from your lips to God's ears." more on this story
