Stephen Gyllenhaal Opens Up About His Prostate Cancer Journey

Director Stephen Gyllenhaal may have landed on a personal topic for his next project — one that weighs heavily on him.

With Oscar-nominated children, Jake and Maggie, and being the father of 10-year-old Luke, Gyllenhaal experienced a surprising moment last year that raised alarms for him.

“Suddenly, my arms and legs felt heavy, like they belonged to an elephant, and I could hardly move,” the 75-year-old director recounted. “I was caught off guard, but I thought it was nothing until it got worse.”

After enduring three days without being able to pee, Gyllenhaal was diagnosed with prostate cancer that had already spread to nearby lymph nodes. For years, he had ignored signs of potential cancer, including concerns about his prostate and elevated levels of prostate-specific antigens (PSA).

In honor of Prostate Cancer Awareness Month, Gyllenhaal is sharing his diagnosis publicly for the first time, urging others to be proactive about testing and managing health issues.

“Usually, you feel secure, so you don’t take action,” he stated about screening. “You might think, ‘I’ll deal with this two years from now.’ It’s crucial to act sooner; catching something early can save your life,” he added.

Prostate cancer is the most frequently diagnosed cancer in men in the U.S., aside from skin cancer.

This year has already seen nearly 314,000 new cases and over 35,000 deaths, making it the second leading cause of cancer-related death in men after lung cancer, according to estimates.

Gyllenhaal’s concerns date back several years; doctors had alerted him in 2020 about his enlarged prostate and rising PSA levels.

PSA is a protein made by both healthy and cancerous prostate cells. High levels of PSA can suggest cancer but aren’t definitive proof.

Amidst the pandemic, he didn’t fully grasp the seriousness, even after receiving a Gleason score of 5 in 2022, which didn’t register as urgent to him.

The Gleason score ranges from 2 to 10, with higher numbers indicating more aggressive cancer.

By October 2024, after what he called a pivotal moment, his Gleason score had jumped to 9.

His PSA level was recorded at 42, considered abnormal when above 4. “That’s when I decided to expedite everything,” he remarked. “My prostate was spiraling out of control.”

After discussing options with friends and doctors, he was referred to Dr. Arpit Chhabra at the New York Proton Center.

Several treatments exist for prostate cancer, including removal of the prostate or focused radiation. Proton therapy, which uses charged particles to target tumors precisely, has advantages over traditional radiation, which can affect surrounding healthy tissue.

During his nearly two months of treatment, Gyllenhaal temporarily relocated to Brooklyn, where he found solace in the beauty of sunrise during his daily commutes.

While he didn’t experience many side effects from radiation, the hormonal medication that lowered his testosterone proved challenging. He struggled with memory issues as well.

Despite the hurdles, he remains hopeful about his recovery.

“I don’t quite understand how Proton therapy works, but it has felt almost miraculous,” he shared.

Though there’s no history of prostate cancer in his famous family, Gyllenhaal’s diagnosis puts his sons Jake and Luke at higher risk.

Gyllenhaal mentioned that Jake was particularly worried, noting, “He was anxious that I wasn’t addressing it properly.” He added that Jake’s doctor reassured him that he was receiving top-notch care.

Gyllenhaal has been open with Luke about the illness, intending to continue those conversations as his son matures.

Men at increased risk for prostate cancer should consider starting to test between the ages of 40 and 45, while those at average risk typically should start between 45 and 50. Screening every 2 to 4 years is advised for men aged 50 to 69.

As Gyllenhaal rang the bell to signify the end of his treatment, he emphasized that he does not claim to be cancer-free yet. He’s still undergoing hormone therapy, along with heart medication.

Additionally, he’s contemplating a book about his health journey that might surprise some readers.

“It sounds a bit counterintuitive, but this has been one of the best things to happen to me,” he confessed. “It opens your eyes to life rather than living in a bubble,” he added, acknowledging the contrast to the fantasy world of Hollywood.
