Prostate Cancer: Common, Often Slow, and Highly Treatable

What is prostate cancer?

The prostate is a small, walnut-sized gland below the bladder that helps make the fluid part of semen. Prostate cancer begins when cells in this gland start to grow uncontrollably.

What sets prostate cancer apart from many other cancers is how variable it is. Many prostate cancers are slow-growing and stay confined to the gland, sometimes never causing symptoms or threatening a man's life — in fact, many men die with prostate cancer rather than from it. Others are aggressive and can spread beyond the prostate. A central goal of modern care is telling these apart so that treatment matches the actual risk.

The key idea: Not every prostate cancer needs immediate treatment. Distinguishing low-risk cancers that can be watched from higher-risk ones that need action is the foundation of today's approach — and it helps men avoid unnecessary side effects.

Risk factors

Several factors raise the likelihood of developing prostate cancer:

• Age — the biggest risk factor; cases rise sharply after 50.
• Family history — having a father or brother with prostate cancer increases risk, as do inherited gene changes such as BRCA1 and BRCA2.
• Race and ethnicity — Black men are diagnosed more often, tend to develop it younger, and are more likely to have aggressive disease.
• Lifestyle factors — diet and other factors may play a role, though their influence is less clear-cut.

A significant disparity: Black men face notably higher rates of prostate cancer and are more than twice as likely to die from it. Earlier conversations about screening — often starting around age 45, or earlier with a family history — can make a real difference. If this applies to you, it's worth raising with a doctor sooner rather than later.

Signs and symptoms

Early prostate cancer usually causes no symptoms at all — which is exactly why screening exists. When symptoms do appear, they may include:

• Needing to urinate often, especially at night
• Trouble starting or stopping urination, or a weak stream
• Blood in the urine or semen
• Difficulty getting or keeping an erection
• Pain in the hips, back, or pelvis if the cancer has spread

Importantly, these same urinary symptoms are far more often caused by a non-cancerous enlarged prostate (BPH), which is very common with age. Symptoms alone don't mean cancer — but they're worth evaluating.

Screening and diagnosis

Screening aims to catch prostate cancer early, when it's most treatable. The main tools are:

• PSA blood test — measures prostate-specific antigen, a protein that can be elevated in prostate cancer (but also in non-cancerous conditions).
• Digital rectal exam (DRE) — a physical check of the prostate.

If results are concerning, next steps may include an MRI, followed by a biopsy to confirm the diagnosis. A pathologist assigns a Gleason score (or Grade Group), which grades how aggressive the cancer looks — a crucial input for deciding on treatment.

Screening is a personal decision: PSA screening saves lives, but it can also lead to detecting slow cancers that would never have caused harm, sometimes resulting in unnecessary treatment. Because of this trade-off, experts recommend a shared decision with your doctor, weighing your age, risk, and preferences rather than a one-size-fits-all rule.

Treatment options

Treatment depends on how aggressive the cancer is, whether it has spread, and a man's overall health and preferences. Options range from watching and waiting to active treatment.

Active surveillance

For low-risk cancers, closely monitoring with periodic PSA tests, exams, and biopsies — treating only if the cancer shows signs of progressing.

Surgery

Removing the prostate (radical prostatectomy), often with nerve-sparing techniques to reduce side effects.

Radiation therapy

External beam radiation or internal seeds (brachytherapy) to destroy cancer cells.

Hormone therapy

Lowering testosterone, which fuels prostate cancer growth — often used for more advanced disease.

Advanced or spread cancer may also be treated with chemotherapy, targeted therapies, or newer immunotherapies. Because treatments can affect urinary and sexual function, discussing potential side effects with your care team is an essential part of choosing a path.

An encouraging reality: When found early, prostate cancer has one of the highest survival rates of any cancer. Even for cancer that has spread, treatments continue to improve, helping many men live well for years.

Key statistics:

• 1 in 8 — Men will be diagnosed with prostate cancer in their lifetime
• ~99% — 5-year survival when caught while still localized
• 65+ — Most cases are diagnosed in men over 65
• 2nd — Most common cancer in men worldwide
