Actress and activist Jane Fonda says her cancer is now in remission three months after announcing she had non-Hodgkin lymphoma.

"Last week, my oncologist told me my cancer is in remission, and I can discontinue chemo," she said in a blog post called BEST BIRTHDAY PRESENT EVER!!!

Fonda, 84, said her first four chemotherapy treatments were "rather easy," and she only experienced some fatigue. But she said her most recent treatment was more difficult and lasted two weeks, "making it hard to accomplish anything."

The blog post continued, "I am feeling so blessed, so fortunate."

"I thank all of you who prayed and sent good thoughts my way," she posted. "I am confident that it played a role in the good news."

Fonda announced her diagnosis in September on Instagram and said she expected to undergo chemotherapy for six months.

According to the American Cancer Society (ACS), non-Hodgkin's lymphoma starts in white blood cells, generally in the lymph nodes and lymphatic tissues that are part of the immune system. ACS said the overall 5-year relative survival rate for people with NHL is 73%.

Fonda also highlighted climate change in her post. She reminded fans of Fire Drill Fridays (FDF), a weekly rally created by Fonda to urge U.S. lawmakers to address global warming. The rally is sponsored by Green Peace and inspired by climate leader Greta Thunberg and Rev. Barber's Moral Mondays.

The FDF website notes, "From its inception in October 2019 until pandemic shutdowns turned FDF virtual, thousands of people showed up at weekly rallies to support climate action, millions amplified calls for action on social media, and more than 600 people engaged in civil disobedience, and were arrested."

"Since moving online, 11 million people have tuned into FDF virtual shows featuring frontline activists, celebrities, experts, and movement leaders. Now, heading into 2023, Fire Drill Fridays is back in the streets!"

Fonda closed her post by condemning Senator Manchin and Senator Schumer's efforts to repress climate change legislation.

"In September, 11 leaders of environmental, labor, and EJ organizations were arrested for protesting the deal, which was defeated on the first attempt and then brought back by Senators Manchin and Schumer a 2nd time. It was defeated again, but last week we learned the senators were trying again to attach this horrific side deal to another bill," Fonda said.

She asked fans to "Please call or write your senator(s) demanding they oppose this Dirty Deal."
