Understanding PSA – IV_A

Understanding PSA

Your PSA level is above the normal range. However, given your age or medical history, further evaluation may or may not be worthwhile. Speak with your doctor about appropriate follow-up.

Your options include

  • a “watch and wait approach” with repeat testing in several months
  • referral to a urologist (prostate specialist)

You have reached the end of this guide. What would you like to do?

Understanding PSA – III

Understanding PSA

Next, we need to know your most recent PSA test result. Usually this is a number between 1.0 and 10.0 (PSA is measured in nanograms per milliliter, or ng/ml).

What was your most recent PSA level?

Understanding PSA – I

Understanding PSA

Most doctors recommend waiting until age 50 to start PSA testing. That’s because prostate cancer is uncommon before this age. However, PSA levels are sometimes checked in men younger than age 50 because they have a risk factor for prostate cancer, such as having a close family member with the disease or being African-American (African American men are more likely than other men to develop prostate cancer and can develop an aggressive form of the disease at a young age).

Understanding PSA – Introduction

Understanding PSA – Introduction

Welcome to this Decision Guide about PSA testing.

Prostate-specific antigen, or PSA, is a blood test used by many doctors to screen for prostate cancer. If you’ve had your PSA level checked, you may have been told that your results were “normal” or “abnormal.” However, some men would like to know more about what their PSA level means.

This tool provides more information about PSA levels, and what’s considered to be reassuring or worrisome for men of different ages.

What is magnetic resonance imaging (MRI)?

This imaging technique, which uses a powerful magnet and a computer to generate pictures of the body’s organs and tissues, can be used to diagnose prostate cancer or pinpoint the tumor’s location.

What is transrectal ultrasonography (TRUS)?

Transrectal ultrasonography (TRUS) can create images of the prostate gland using sound waves. Doctors may recommend TRUS when they suspect prostate cancer based on an abnormal DRE or an elevated PSA.

Newer screening tests

Researchers are developing more screening tests for prostate cancer. Like the PSA test, they rely on biomarkers, such as antigens or proteins, which are elevated or may only be present in men who have prostate cancer. The hope is that these newer tests will better detect existing cancers (better sensitivity), and will not raise the alarm for cancer when it is not present (better specificity).

What is a digital rectal exam (DRE)?

In this test, the doctor inserts a lubricated, gloved finger into the rectum and feels the surface of the prostate to determine whether it is swollen or has any lumps or abnormally textured areas (see Figure 1). This exam also helps doctors screen for diseases of the rectum, such as rectal cancer.

Cancer prevention trial (SELECT) comes to a halt

The National Cancer Institute discontinued the study after finding evidence that selenium and vitamin E supplements did not prevent prostate cancer.

Intermittent hormone therapy: A patient’s story

The jury is still out on whether intermittent hormone therapy, which involves repeated cycles of hormone therapy followed by breaks in treatment, might help patients live longer than continuous hormone therapy. But Patrick Kirby’s story might help patients who are debating various options in hormone therapy.

Hematospermia demystified

Spotting blood in your semen can be worrisome, but it’s usually not cause for alarm.

A Harvard expert shares his thoughts on testosterone-replacement therapy

Dr. Abraham Morgentaler, an associate professor of surgery at Harvard Medical School and the director of Men’s Health Boston, shares his views on current controversies regarding testosterone-replacement therapy.

New options for treating erectile dysfunction

Penile rehabilitation, which typically consists of oral or injected medications, alone or with other interventions, may help restore erectile function after treatment for prostate cancer. However, this therapy remains controversial.

Erectile dysfunction and heart disease: What’s the connection?

Even if your doctor has given you a clean bill of health, beware: problems getting or keeping an erection firm enough for sexual intercourse may signal trouble, especially cardiovascular disease, down the road.

Harvard experts discuss benign prostatic hyperplasia drug treatments

Three Harvard doctors talk about who needs to be treated for BPH, what medications should be prescribed, and what side effects you need to be aware of.

Your benign prostatic hyperplasia medication: When to consider a change

A look at treatment options and trade-offs

If you are like many of the 14 million men in the United States who have been diagnosed with benign prostatic hyperplasia (BPH), you’ve probably been taking the same medication, at the same dose, for years. If so, consider the experiences of two patients, both of whom were taking some type of medication for BPH. Their names have been changed, but all other details are accurate (see “Jack Muriel” and “Henry Banks”).

Treating erectile dysfunction with penile implants

Penile implants, an option patients with erectile dysfunction probably hear little about, might offer a lasting and satisfying “cure.” Abraham Morgentaler, M.D., director of Men’s Health Boston, explains how.

Strength training exercises

Regular physical activity can help keep you — and your prostate — healthy

By now, we’ve all heard about the value of exercise in maintaining good health. Literally hundreds of studies conducted over more than half a century demonstrate that regular exercise pares down your risk of developing some deadly problems, including heart disease, stroke, and certain types of cancer (colorectal cancer, for example). It also eases the toll of chronic ailments like high blood pressure, diabetes, and arthritis.

Eating for prostate health (Part 1 of 2)

Two registered dietitians from Harvard-affiliated hospitals tout the benefits of fruits, vegetables, and whole grains

“What can I eat to reduce my risk of developing prostate cancer?” That’s one of the most common questions physicians hear from men concerned about prostate health. Undoubtedly, many hope to hear their doctor rattle off a few foods guaranteed to shield them from disease. Although some foods have been linked with reduced risk of prostate cancer, the proof is lacking, at least for now.

Outcomes research in prostate disease

When it comes to prostate cancer and other prostate diseases, how accurate are the statistics we hear? Can patients rely on reported figures to determine their risk of suffering complications such as incontinence and impotence? Why do data vary from one organization to another? Three experts discuss these questions and the growing field of outcomes research.

Maintaining physical and emotional health during prostate cancer treatment: A patient’s story

Mr. Williams, a successful business owner in his mid-60s, describes how he was able to maintain his sex life and other aspects of his physical emotional well-being during and after treatment for prostate cancer.
