The whole month, every year
Prostate Cancer Awareness Month covers all 30 days of September, not a single date or a floating week inside it. There is no nth-weekday arithmetic to compute and no rival set of dates from a competing organization to sort out; every federal, medical, and advocacy source treats the full month the same way.
What has genuinely changed since the observance began is not the calendar but the name attached to it, and the paperwork behind that name. A 1999 designation covered prostate health broadly; a 2003 proclamation narrowed the focus to cancer specifically. That distinction, not the date range, is the part most calendar sites skip past.
1989: A screening week, not yet a month
The observance's roots are in a single question: could men be persuaded to get screened for a disease few of them talked about? In 1989, the newly formed Prostate Cancer Education Council, a coalition spanning urology, oncology, behavioral research, and patient and minority advocacy groups, commissioned a health survey that March to measure public knowledge, attitudes, and health practices around prostate cancer. That summer, the Council held a press conference in New York City and designated September 17 to 24, 1989, as the first Prostate Cancer Awareness Week.
The week was not a symbolic gesture. It became, by several accounts, the largest single cancer-screening program run in the United States at the time, offering free or low-cost prostate exams at sites around the country. Academic follow-ups tracked the campaign's growth for years afterward, including a peer-reviewed summary of findings published in CA: A Cancer Journal for Clinicians covering the 1997 iteration, September 22 to 28 that year, eight years into the campaign.
1999 and 2001: A foundation names the month, then Congress names the disease
A full month did not exist until ten years after the first week. In 1999, the American Foundation for Urological Disease (AFUD), the organization that later became the Urology Care Foundation in 2011, designated all of September as National Prostate Health Month. The name mattered: this was a broader observance about prostate health in general, covering conditions like prostatitis and benign prostatic hyperplasia alongside cancer, not a cancer-specific campaign.
The cancer-specific name came from Congress two years later. On August 3, 2001, the Senate agreed to Resolution 138 by unanimous consent, a measure sponsored by Senator Conrad Burns of Montana and cosponsored by 58 other senators. It asked the President to proclaim September 2001 as "National Prostate Cancer Awareness Month," citing an estimated 198,100 diagnoses and 31,500 deaths that year. A Senate resolution of this kind is a request, not an order; it does not by itself create a proclamation, set a permanent name, or fix a date.
2001 to 2003: A name attached to two different months
What the President actually proclaimed did not match what the Senate had asked for. On November 1, 2001, George W. Bush signed a proclamation declaring November 2001, not September, "National Prostate Cancer Awareness Month," the first presidential use of the cancer-specific name on record. For that one year, the name existed, but attached to a different month than the one Congress had in mind.
September and the name came together in a documented proclamation two years later. On September 1, 2003, Bush signed Proclamation 7700, which read in part: "Prostate cancer is the second most common form of cancer among men in the United States. This year alone, it is estimated that more than 220,000 new cases of prostate cancer will be diagnosed and that nearly 29,000 men will die from this disease." That proclamation named September 2003 National Prostate Cancer Awareness Month, and later examples cited here also use September; this is not an exhaustive year-by-year verification.
Three weeks inside one month
September carries more than one nested observance related to prostate health, a detail most calendar listings compress into a single line. Prostatitis Awareness Week runs September 10 to 16. The original 1989 campaign used September 17–24, while its documented 1997 iteration used September 22–28. Listings that repeat the first window should not be read as proof of a permanent date rule. Benign Prostatic Hyperplasia (BPH) Awareness Week closes out the month, September 24 to 30.
One observance that is not part of this cluster, despite sharing an audience: Testicular Cancer Awareness Week, which falls in a completely different part of the year, the first week of April. A reader who sees "prostate" and "testicular" awareness campaigns both described as men's-health observances can reasonably assume they share a season. They do not. This site's Ovarian Cancer Awareness Month page, covering a different September cancer observance, lays out its own version of an informal campaign outgrowing its original scope: a single 1998 presidential week that a nonprofit expanded into a full month two years later.
A proclamation nobody has to renew
Since Bush's 2003 proclamation put the name back on September, the presidential examples cited here have marked the month there, though the format has shifted. Obama proclaimed it formally in at least 2011 and 2015. Biden issued a full proclamation in 2022, published in the Federal Register the following month. Trump's first administration issued a statement in 2017 focused on falling incidence and mortality rates; his second administration issued a September 2, 2025 presidential message, a different document format than a proclamation, stating that "every year, more than 300,000 men are diagnosed with prostate cancer, and more than 35,000 die from the disease." Congress has added its own layer on top of the executive branch's: the Senate passed non-binding resolutions naming specific years in 2021 (S.Res.378) and 2022 (S.Res.776), and the House introduced a matching resolution for 2025 (H.Res.675). The cited measures and presidential announcements document those particular years, without supplying a standing renewal law or verifying every intervening year.
The American Cancer Society's most recent estimate, for 2026, puts the numbers higher than the 2025 presidential message: about 333,830 new diagnoses and 36,320 deaths, with roughly 1 in 8 men expected to be diagnosed with prostate cancer at some point in their lives. The two figures are not contradictory; they come from different years and different estimating methods, and both describe a disease whose count of new cases has been rising by about 3 percent a year since 2014, according to the ACS. Prostate Cancer Awareness Month carries no legal holiday status. The observance itself does not require federal-office closures or create a right to paid leave; what happens instead is decentralized, through screening events, the light blue awareness ribbon, and campaigns run by hospitals, advocacy groups, and employers throughout the month.
Two neighboring campaigns on this calendar have different founding histories and forms of recognition, so their instruments should be read individually. Breast Cancer Awareness Month falls in October; its guide identifies year-specific public laws in the early 1990s, a different instrument from the cited Senate prostate-cancer resolutions. Movember, which raises money for prostate and testicular cancer research every November, took a different route entirely: its official history begins with a private Melbourne moustache challenge, rather than a government founding instrument identified in that guide. International Men's Day, each November 19, covers men's health as one part of a broader observance rather than as its whole focus.
