Over the weekend, President Joe Biden’s office announced that the former president has prostate cancer that has spread to his bones.

“On Friday he was diagnosed with prostate cancer, characterized by a Gleason score of 9 (Grade Group 5) with metastasis to the bone,” the official statement read.

The statement also categorized his diagnosis as “a more aggressive form of the disease” and noted that there are certain hormone-based treatments available.

Biden’s diagnosis sent shockwaves throughout the country and the world, along with people who have faced this diagnosis themselves.

One in eight people are diagnosed with prostate cancer in the United States, making it the most common type of cancer in men. There are treatments available, whether it’s caught early or in later stages, like Biden’s.
