Jason Collins spent years making sports history, but his final public battle became a heartbreaking fight against one of the most aggressive cancers known to medicine.
The former NBA player died Tuesday at 47 following a glioblastoma diagnosis, a fast-growing and often inoperable brain tumor that carries one of the lowest survival rates among major cancers. Collins first revealed his condition in late 2025, sharing that he had been undergoing surgeries and intensive treatment while continuing to advocate for authenticity and visibility.
According to medical experts, glioblastoma develops from cells in the brain called astrocytes and is considered the most common malignant brain tumor in adults. The cancer spreads quickly into nearby brain tissue, which often makes complete removal impossible even after surgery. Doctors say the disease can impact speech, memory, vision, mobility, and personality depending on where the tumor forms.
Symptoms frequently include severe headaches, nausea, seizures, confusion, balance problems, and sudden cognitive changes. While treatment usually involves surgery, radiation, and chemotherapy, glioblastoma almost always returns because microscopic cancer cells remain embedded in the brain.
The average survival time after diagnosis is typically between 12 and 18 months, though outcomes vary based on age, tumor location, and treatment response.
Collins became a major cultural figure in 2013 when he publicly came out as gay in a groundbreaking Sports Illustrated essay.
“I’m a 34-year-old NBA center. I’m Black, and I’m gay,” Collins wrote at the time.
The moment transformed him into the first openly gay active player in the four major American men’s professional sports leagues and sparked a national conversation about sexuality in sports.
Tributes poured in Tuesday from athletes, politicians, and entertainment figures honoring Collins not only for his NBA career, but for changing the culture surrounding professional athletics.
Collins retired from basketball in 2014 and later became a speaker, activist, and advocate for LGBTQ visibility. He married film producer Brunson Green in 2025.
His impact ultimately stretched far beyond basketball courts. Jason Collins became proof that honesty could shift an entire sports culture, even while facing unimaginable personal battles behind the scenes.
