Speaking to Access Hollywood, the soul singer expressed confusion as to how the cancer rumour came about.
"I don't know where 'pancreatic cancer' came from," she said. "I was sitting there reading the newspaper and it was saying someone in my family said that. No-one in my family ever said that to anybody."
While Franklin did not divulge the specific ailment that she is suffering from, she revealed that a recent surgery may have added "15 to 20 more years" to her life.
"It's getting better every day. I plan on keeping this weight that I have now - I'm so happy with it," she asserted.
Over the course of her six-decade career, the 'Respect' musician has scored five platinum selling LPs and more than a dozen US top ten singles.
Earlier this week, Franklin remarked that she wants Halle Berry to portray her in a big screen biopic.
