Quick answer

Excluding non-melanoma skin tumors, prostate cancer is the most common cancer among men in Brazil, with an estimated 77,920 new cases per year from 2026 to 2028.1 Early on, it usually causes no symptoms.2 When it is confined to the prostate, it can be cured, and some low-risk tumors are simply monitored closely.3

What it is

The prostate sits below the bladder, in front of the rectum, around the urethra. Cancer begins when cells of the gland start growing out of control.

Its behavior varies greatly from one man to another. Some tumors would never cause symptoms, and others are aggressive.2 That is why the Gleason score and ISUP grade group, which appear in the biopsy report, weigh so heavily in the decision.

Who is at higher risk

Age, family history, African ancestry and a BRCA2 gene mutation all count. These factors determine when to start evaluation:2,5

GroupStart evaluation at age
Men in general50
Black men45
First-degree relative with the disease45
BRCA2 gene mutation40

After age 75, the Brazilian Society of Urology advises evaluation only for men with a life expectancy of more than 10 years.5

How it is diagnosed

  1. PSA and digital rectal examPSA is a blood test. An abnormal value is usually repeated before going further.2
  2. MRIIt comes before the biopsy and shows whether there is a suspicious area.2
  3. BiopsyThe biopsy removes small samples of the prostate for the pathologist to examine.
  4. Pathology reportIf there is cancer, the report gives the Gleason score and ISUP grade group, which show how aggressive the tumor is.

Once the diagnosis is made, we assess whether the disease has left the prostate. PSMA PET is the most sensitive test for this.3

Three sections of the prostate: tumor confined to the prostate, tumor extending beyond the prostate and tumor that has reached other parts of the body.
How far the tumor has spread. This staging guides treatment.

Can it be cured?

When the tumor is confined to the prostate, it can be cured.3

ProtecT, a British study, followed 1,643 men with localized tumors for 15 years. In that period, 2.7% died of the disease, with similar numbers across active monitoring, surgery and radiotherapy.4 This result comes from one study and does not predict what will happen to each person.

When the cancer has already spread, treatment aims to control the disease, with hormone therapy and other medications.6

Treatment options

The choice starts from the risk group, your health and what matters most to you.3

SituationWhat is usually discussed
Low riskActive surveillance
Intermediate riskSurgery or radiotherapy. Active surveillance in selected cases
High risk and locally advanced diseaseSurgery or radiotherapy, often with hormone therapy
Metastatic diseaseHormone therapy and other medications

How I approach it

In my practice, I start with each man's risk: age, family history and previous test results. I go through the result calmly and explain the options that make sense for him, including active surveillance when it fits. The decision is made together with the patient, and the family takes part if he wishes.

When to see a urologist

  • From age 50, even without symptoms, or earlier if you are in a higher-risk group
  • If your PSA or rectal exam is abnormal
  • If you already have a biopsy and want to understand the report
  • If you have been diagnosed and want to talk about the options

Frequently asked questions

Can prostate cancer be cured?

When it is confined to the prostate, it can be cured.3 In a British study of 1,643 men with localized tumors, 2.7% died of the disease within 15 years.4 That number does not predict what will happen to each person, because the chance depends on the risk group.

Does prostate cancer cause symptoms?

Early on, it usually does not. Symptoms generally appear late in the course of the disease.2 That is why evaluation is recommended even for men who feel well.5

At what age should I start testing?

From age 50. Black men and men with a first-degree relative with the disease start at 45.2,5 Men with a BRCA2 gene mutation start at 40.2

Does every prostate cancer need surgery?

No. In low-risk disease, active surveillance is the approach recommended by the European guideline.3 In other cases, surgery and radiotherapy are discussed with the patient, along with the effects of each.

Can transgender women have prostate cancer?

Yes. Cases have been described in transgender women in a series from the United States veterans health system.7 Anyone who has a prostate can talk to a urologist about evaluation.
