“Jeana is now in her fifth week of chemotherapy, radiation, and immunotherapy,” she added. “The treatments are relentless. She is exhausted, struggling to stay awake, and becoming malnourished because the pain in her tongue and throat makes swallowing even the smallest bites or sips incredibly difficult. Every day is a battle just to get enough nutrition and hydration to continue treatment.”

Additionally, the financial burden of Keough’s cancer treatment has been just as significant as the physical one.

“On top of the physical toll, she has been unable to work,” Bosworth wrote. “Because her job is commission-based, the loss of income has created an enormous financial burden at the very time she needs to focus all of her energy on healing.”

But as Keough continues to navigate her health battle, Bosworth remains in awe of her mother’s strength.

“Everyone who knows her knows this: she’s almost impossibly optimistic in the face of terrifying things—wildfires, cancer, uncertainty,” Bosworth wrote in a July 19 Instagram post. “Yet somehow she’s always been afraid of the simplest thing: being vulnerable enough to ask for help.”
