On screen

Hubert Humphrey — a former U.S. Vice President and longtime Senator from Minnesota — was diagnosed with bladder cancer during his years in public life. He spoke openly about his illness, including sharing in 1977 that it had become terminal, and he continued to serve in the Senate. Humphrey died in January 1978 at age 66. His willingness to be public about his diagnosis, at a time when many kept such news private, is part of how he is remembered.

The reality

According to the National Cancer Institute, bladder cancer occurs when cells in the bladder start to grow without control. The bladder is a hollow, balloon-shaped organ in the lower abdomen that stores urine made by the kidneys. NCI explains that almost all bladder cancers are urothelial carcinomas (also called transitional cell carcinomas), which begin in the cells that line the inside of the bladder. Other types, such as squamous cell carcinoma and adenocarcinoma, are rare. NCI also notes that bladder cancer can be described as non-muscle-invasive (not yet reaching the muscle wall) or muscle-invasive — a distinction that helps guide care.

What the story gets right — and what to remember

Humphrey's story reflects the reality that people can continue meaningful work while living with cancer. But his experience was his own, and treatment for bladder cancer has advanced considerably in the decades since. Every person's diagnosis is different. His story is a way to learn and to remember, not a prediction for anyone else and not medical advice.

Awareness, screening & prevention

NCI identifies tobacco use — especially cigarette smoking — as a major risk factor for bladder cancer, and it offers information on other risk factors and steps that may lower risk. NCI also has information on bladder cancer screening for people at high risk. One symptom NCI highlights is blood in the urine, which can also be caused by less serious conditions but is a warning sign worth having checked. Anyone noticing such a change should speak with a healthcare professional.

Turning a story into something useful

By speaking openly, Humphrey helped make cancer a subject people could discuss rather than hide. A useful response today is to learn what bladder cancer is, understand that not smoking is one of the clearest ways to lower risk, and pay attention to warning signs like blood in the urine. Sharing accurate information and supporting free cancer education helps others do the same.

Questions to ask a healthcare team

  • What could blood in the urine mean, and how is it evaluated?
  • Am I at higher risk for bladder cancer, and does screening make sense for me?
  • How does quitting tobacco affect cancer risk?
  • Where can I find reliable, plain-language information about bladder cancer?
