Jane Fonda, 84, Diagnosed With Cancer

LOS ANGELES, CA — Actress Jane Fonda is undergoing chemotherapy for non-Hodgkin’s Lymphoma, she announced Friday.

The 84-year-old star and activist has been in treatment for six months, and she assured fans in a social media post Friday afternoon that her prognosis is good.

"My dear friends, I have something personal I want to share. I’ve been diagnosed with non-Hodgkin’s Lymphoma and have started chemo treatments," she wrote. "This is a very treatable cancer. 80% of people survive, so I feel very lucky."

The two-time Oscar winner and “Grace and Frankie” star, famous for her environmental activism, tied her announcement to the cause.

"We also need to be talking much more not just about cures but about causes so we can eliminate them. For example, people need to know that fossil fuels cause cancer. So do pesticides, many of which are fossil fuel-based, like mine," she wrote. "I’m doing chemo for 6 months and am handling the treatments quite well and, believe me, I will not let any of this interfere with my climate activism."

She went on to thank her fans for their support, saying she knows so many families know what she is going through.

"Almost every family in America has had to deal with cancer at one time or another and far too many don’t have access to the quality health care I am receiving and this is not right," she wrote. "Cancer is a teacher and I’m paying attention to the lessons it holds for me. One thing it’s shown me already is the importance of community. Of growing and deepening one’s community so that we are not alone. And the cancer, along with my age --almost 85-- definitely teaches the importance of adapting to new realities."

Fonda urged her fans to keep fighting and to vote in the midterm elections.

"We’re living through the most consequential time in human history because what we do or don’t do right now will determine what kind of future there will be and I will not allow cancer to keep me from doing all I can," she wrote. "The midterms are looming, and they are beyond consequential so you can count on me to be right there together with you as we grow our army of climate champions."
