When you look at the raw numbers for California prostate cancer new cases 2019 2020 2021 2022 2023, the story isn't just about a single line going up or down. It's actually a bit of a rollercoaster. Honestly, if you were to just glance at the chart, you'd see a weird dip in 2020 that might make you think the disease was going away. It wasn't.
In 2019, California was already seeing a concerning trend. After years of the numbers staying relatively flat or even dropping, they started to creep back up. Experts like those at the California Cancer Registry (CCR) and the American Cancer Society (ACS) noticed that we were hitting about 25,000 to 26,000 new cases a year around that time.
Then 2020 hit.
The COVID-19 "Data Ghost"
You’ve probably guessed what happened next. The pandemic didn't stop cancer, but it definitely stopped people from going to the doctor. Because of the lockdowns and the general fear of hospitals, screening rates cratered. In California, the recorded number of new cases for 2020 actually looks lower on paper. But don't let that fool you. It's what researchers call a "diagnostic deficit." Basically, the cancer was there; we just weren't finding it yet.

By 2021, the floodgates opened. As people started heading back to their primary care physicians, we saw a massive spike. In 2021 alone, California saw an estimated 25,880 new cases. That was nearly a 28% jump from the "artificial" lows of 2020. This wasn't just a return to normal; it was a backlog of undiagnosed cases finally hitting the books.
Breaking Down the Numbers: 2022 and 2023
As we moved into 2022 and 2023, the trend became even more alarming. The American Cancer Society's data for 2023 suggested that prostate cancer was increasing by about 3% every year nationally, and California was right at the forefront of that shift.

Well, a big part of it is the change in screening guidelines from about a decade ago. For a while, the U.S. Preventive Services Task Force (USPSTF) backed off on recommending routine PSA (Prostate-Specific Antigen) tests because they were worried about over-treatment. But the unintended consequence was that we stopped catching the aggressive stuff early.
- 2019: Stable but starting to rise (approx. 25,000 cases).
- 2020: Significant dip due to missed screenings (the "COVID gap").
- 2021: Massive rebound as healthcare resumed (over 25,800 cases).
- 2022: Continued upward trajectory, especially in advanced stages.
- 2023: Estimates reached nearly 27,000+ new cases as the population ages and late-stage diagnoses rise.
The Problem With "Advanced" Cases
Here is the part that kind of keeps oncologists up at night. It's not just that there are more cases; it's that the cases we're finding are further along. A study from UCSF published in early 2025 (looking back at this 2019-2023 window) pointed out that distant-stage prostate cancer—meaning the cancer has already spread to other parts of the body—has been increasing by about 6.7% per year in California.
When cancer is caught early, the 5-year survival rate is nearly 100%. When it’s "distant" or metastatic, that survival rate drops to around 38%. The fact that California is seeing more of these late-stage diagnoses is a huge red flag.

Who is Most at Risk in California?
The data doesn't hit every community the same way. Honestly, the disparities are pretty gut-wrenching. Black men in California are diagnosed at significantly higher rates and, more importantly, are about two to four times more likely to die from the disease than men of other races.
Regional differences matter too. If you live in the Central Coast or the North Coast, your statistical likelihood of a late-stage diagnosis has been higher lately compared to someone in the San Francisco Bay Area. This likely comes down to "healthcare deserts" and how easy it is to get to a specialist.
What You Should Actually Do
If you’re over 50—or 45 if you’re Black or have a family history—you need to have a real talk with your doctor. Don't just wait for them to bring it up. The "wait and see" approach that became popular in the mid-2010s is being re-evaluated because of these exact 2019-2023 numbers.
The PSA test isn't perfect. It can't always tell the difference between a "slow-growing" cancer and a "killer." But it’s the best smoke detector we’ve got.
Actionable Next Steps:
- Check your records: See when your last PSA test was. If it was before 2019, you’re essentially flying blind in a period where late-stage cases are rising.
- Assess your family tree: If your dad or brother had it, your risk profile changes completely. You should be screened earlier.
- Look for symptoms, but don't rely on them: Early prostate cancer usually has zero symptoms. If you're waiting for pain or trouble urinating, you might be waiting too long.
- Consult a specialist: If your PSA comes back "borderline," ask about newer genomic tests or a 3T MRI, which can help determine if a biopsy is actually necessary.
