What Happens If My Biopsies Comes Back Negative

What Is a Normal PSA for a Man Without Prostate Cancer? | Ask a Prostate Expert, Mark Scholz, MD

Just because your biopsies are negative, does not mean that you do not have cancer in your prostate. You need to be seen on a regular basis for digital rectal examination and PSA testing. If there is significant change in your PSA, we may suggest repeat biopsies. The average risk of finding cancer in a repeat biopsy following a benign diagnosis is about 18%.

Positive Psa Score Association With Other Conditions

The amount of PSA in your blood test may increase with other prostate conditions such prostatitis, enlarged prostate , or within two days after ejaculation.

Rest assured, even though your results may be high, it doesnt necessarily mean you have prostate cancer. Just a greater risk of developing it.

Should I Have The Covid

This is a personal decision, and only you can decide whether to have the vaccine. But it is the best way to protect yourself against severe COVID-19 illness.

There is a lot of information on the internet about vaccines and its hard to know which information to trust. You should be able to find the most up-to-date information about COVID-19 vaccines on the NHS website.

It may help to talk to your family or friends if youre not sure what to do. Your doctor or nurse can also talk to you about the vaccine and help you decide whats right for you.

What Is Transrectal Ultrasound

Transrectal ultrasound is the examination of prostate using a machine called ultrasound. We insert a finger like probe into the rectum to examine the prostate. Ultrasound creates a picture of prostate using high-frequency sound waves. These sound waves come out of the probe and are transmitted through body tissues. The sound waves then bounce off the tissue and return to the probe. These returning sound waves are called echoes and are translated and recorded into photographic images. Transrectal Ultrasonography provides excellent visualization of the prostate and abnormalities that may be present in the prostate. We can also easily guide the biopsy needle under ultrasound guidance into the prostate where cancer is suspected.

The ultrasound machines in our offices are capable of doing color doppler studies and three dimensional reconstruction of the gland. Usually there is increased blood flow within the cancerous lesion or adjacent to the lesion and color doppler helps us precisely guide the biopsy needle into the lesion for accurate biopsy.

Transrectal ultrasonography is also used to estimate the prostate volume accurately to calculate PSA density.

Transrectal ultrasonography also provides images sensitive enough to defect capsular involvement and extention of cancer into the seminal vesicles .

What Does It Mean

Guidance updated on PSA testing for prostate cancer

A normal PSA level is less than 4 ng/mL. Higher PSA levels mean the risk of prostate cancer is increased. Heres how your PSA relates to cancer risk:

  • Less than 4 ng/mL: The likelihood of prostate cancer is lower if your PSA level is less than 4 ng/mL. But this level doesnt completely rule out cancer. Around 1 in 7 people with normal PSA levels are discovered to have prostate cancer when more testing is done .

  • Between 4 and 10 ng/mL: This means the risk of prostate cancer is about 1 in 4.

  • Higher than 10 ng/mL: At this level, there is about a 50% chance that you have prostate cancer.

When interpreting your PSA level, its important to know if you have any other condition that could affect your PSA level. This way youll know whether you are at risk for having a low PSA level when cancer is present. Or a high level when there is no cancer.

Serum Insulinlike Growth Factor

Insulinlike growth factor -1, its binding protein , and its receptor have been implicated in the development of prostate cancer. PSA cleaves IGF-1 from its binding protein, allowing this potent growth factor to act on prostate epithelial cells.

Plasma concentrations of IGF-1 have been associated with an increased risk of prostate cancer. In the Physiciansâ Health Study, 152 cases of prostate cancer were matched with 152 controls from the population of 14,916 physicians. Serum samples assayed for IGF-1 at the outset of the study found a positive association with the subsequent development of prostate cancer. Men in the highest quartile for IGF-1 had a relative risk of 2.4 as compared with men in the lowest quartile.

The predominant IGF-1 binding protein, IGFBP-3, has growth-inhibiting properties that diminish the effect of IGF-1. After correcting for IGFBP-3 levels, the risk of developing prostate cancer was 4.5 times greater for the highest quartile than for the lowest quartile.

The clinical usefulness of this assay has yet to be demonstrated, because alternative explanations for these findings may exist. Prostate size and a large overlap in actual values limit the utility of the test but do provide additional information regarding the biology of prostate cancer.

What Does Psa Mean

PSA, or prostate-specific antigen, is a protein produced by the prostate and found mostly in semen, with very small amounts released into the bloodstream. When theres a problem with the prostatesuch as the development and growth of prostate cancermore PSA is released. Sometimes, a mans prostate releases slightly high PSA for other reasons. Rising PSA eventually reaches a level where it can be easily detected by a blood test.

What Are Some Of The Limitations And Potential Harms Of The Psa Test For Prostate Cancer Screening

Detecting prostate cancer early may not reduce the chance of dying from prostate cancer. When used in screening, the PSA test can help detect small tumors that do not cause symptoms. Finding a small tumor, however, may not necessarily reduce a mans chance of dying from prostate cancer. Many tumors found through PSA testing grow so slowly that they are unlikely to threaten a mans life. Detecting tumors that are not life-threatening

that requires treatment.

What Is Considered An Elevated Prostate

Prostate Cancer PSA Scores

Researchers havent settled on a single normal PSA level. Previously, a level of 4.0 ng/mL or higher would lead to more testing, usually a prostate biopsy. During the biopsy, a healthcare provider removes a small sample of prostate tissue to check it for cancer.

However, healthcare providers now consider other issues together with the PSA level to decide whether to perform a biopsy. Your age, general health, family history and health history factor into the decision.

What Is The Prostate

The prostate is a walnut-shaped gland that is part of the male reproductive system. The main function of the prostate is to make a fluid that goes into semen. Prostate fluid is essential for a mans fertility. The gland surrounds the urethra at the neck of the bladder. The bladder neck is the area where the urethra joins the bladder. The bladder and urethra are parts of the lower urinary tract. The prostate has two or more lobes, or sections, enclosed by an outer layer of tissue, and it is in front of the rectum, just below the bladder. The urethra is the tube that carries urine from the bladder to the outside of the body. In men, the urethra also carries semen out through the penis.

Psa Score: A Mans First Encounter With His Prostate

How To Treat Elevated PSA Levels.

Many menâs first encounter with their prostate gland is an elevated PSA score. This is because the prostate gland is well hidden in the body and is usually not a source of any sensory experience. Most men also have no idea what its function is.

This state of blissful ignorance can change all of a sudden when their doctors inform them that their PSA levels are elevated. This is usually the moment when those affected begin to concern themselves with their prostate.

In the case of younger men, the cause of an elevated PSA level often turns out to be an acute condition such as an infection that leads to inflammation. For middle-aged men, the list of typical causes will also include age-related prostate enlargement and prostate cancer.

It is important to bear in mind that if your PSA level is elevated, it is important to determine the specific cause of the elevation, no matter what your age bracket is. And an MRI scan of the prostate represents an optimal means of determining the cause.

If I Have Elevated Psa Levels What Should I Ask My Healthcare Provider

If you have any symptoms of prostate cancer, or if it runs in your family, ask your provider:

  • Should I have regular tests to check my PSA level?
  • What can I do to lower my risk for prostate cancer?
  • What other tests or monitoring do I need?
  • What are my treatment options if I get prostate cancer?
  • What other signs or symptoms should I look out for?

A note from Cleveland Clinic

An elevated PSA level can be a sign of prostate cancer, but it doesnt always mean you have cancer. Your healthcare provider will watch you and do more tests to arrive at a diagnosis. Prostate cancer is often slow-growing and may never become life-threatening. If you have symptoms of prostate problems, such as difficulty urinating, don’t hesitate to let your provider know.

Using The Psa Blood Test After Prostate Cancer Diagnosis

Although the PSA test is used mainly to check for prostate cancer, it can also help your doctor:

  • Choose a treatment. Along with an exam and tumor stage, the PSA test can help determine how advanced a prostate cancer is. This may affect treatment options.
  • Check treatment success. After surgery or radiation, the doctor can watch your PSA level to see if the treatment worked. PSA levels normally fall if all of the cancer cells were removed or destroyed. A rising PSA level can mean that prostate cancer cells are present and your cancer has returned.

If you choose a watchful waiting approach to treatment, your PSA level can tell your doctor if the disease is progressing. If so, youâll need to think about active treatment.

During hormone therapy, the PSA level can show how well the treatment is working and when itâs time to try another treatment.

Factors Influencing Psa Levels

For clinical purposes, prostate-specific antigen is considered specific for the prostate gland but not specific for prostate cancer. A major limitation of PSA as a prostate cancer marker is the overlap in values between benign prostatic hyperplasia and prostate cancer. Normal, hyperplastic, and neoplastic epithelial cells all make PSA, but the amount of PSA produced by cancer cells is 10 times higher per gram of tissue than the amount produced by normal or hyperplastic tissue.

High Psa Levels From A Urinary Tract Infection

Limitations of the PSA Test for Prostate Cancer

“Any infection near the prostate gland, including a urinary tract infection, can irritate and inflame prostate cells and cause PSA to go up,” says Milner.

If youve been diagnosed with a urinary tract infection, be sure to wait until after the infection has cleared up before you get a PSA test. In men, most urinary tract infections are caused by bacteria and respond well to antibiotics.

Having BPH increases your risk for a urinary tract infection.

Prostatitis: A Common Problem In Men Under 50

“The PSA test is a good screening tool for prostate cancer, but it is not very specific,” says Erik P. Castle, MD, a urologist and researcher at the Mayo Clinic in Phoenix, Arizona. “Common causes of inflammation in the gland, called prostatitis, can cause high PSA levels.”

Prostatitis is the most common prostate problem for men younger than 50.

Prostatitis caused by bacteria can be treated with antibiotics. Another, more common type of prostatitis, called nonbacterial prostatitis, can be harder to treat and may last a long time.

What Should I Expect If Im Told I Have Elevated Psa

If your provider finds an elevated PSA level, youll have repeat tests to check your prostate. Many men with elevated PSA levels even those who have prostate cancer live long, healthy lives. Prostate cancer may not need treatment, depending on how slowly the tumor is growing. Keep up with your regular appointments and tests so your care team can keep tabs on your health.

Psa And Beyond: Biomarkers In Prostate Cancer

ABSTRACT: Prostate-specific antigen is one of the best-known biomarkers in medicine. Despite ongoing debate on the utility of this proteolytic enzyme in population screening, PSA continues to play a role in the diagnosis and management of prostate cancer. In an attempt to move beyond problems related to insufficient specificity, investigators are considering ways to enhance the positive predictive value of PSA and its isoforms, and are looking at tests based on several promising biomarkers, including human kallikrein-related peptidase 2 and prostate cancer antigen 3. Assays that have recently become available show promise in reducing the number of unnecessary prostate biopsies and improving detection of clinically significant prostate cancers while avoiding the overdiagnosis and overtreatment of biologically irrelevant tumors.

A literature review suggests multiplexed models combining several biomarkers could help reduce the number of negative prostate biopsies and improve detection of clinically significant prostate cancers.

Investigators are continuing to explore the utility of PSA and its isoforms, as well as a few emerging biomarkers, and expect that multiplexed models based on more cancer-specific biomarkers will eventually pave the way for better prostate cancer diagnosis and care.

Reducing Prostate Cancer Risk Through Diet

When should you have a PSA test?

If you are concerned about developing cancer, then you can follow the existing dietary and lifestyle guidelines for reducing prostate cancer risk, which includes:

  • Limiting processed foods in your diet. The majority of processed foods contain additives, sugar, and salt. These chemical additives are not food-based, and many of them are anti-microbial, which means they not only limit the growth of bacteria and other microbes, to keep the food from rotting, but they also affect the microbes that keep our gut healthy.
  • Reducing red meat consumption. High intakes of red meat have been associated with an increased risk of prostate cancer. It was previously reported in the Health Professionals Follow-up Study that red meat intake was associated with an increased risk of metastatic prostate cancer based on follow-up from 1986 to 1996.
  • Avoiding cows milk and other high-fat dairy products. Research has shown that men who consume a lot of dairy products have an increased likelihood of developing prostate cancer than men who dont eat calcium-heavy diets.
  • Increasing the amount of fruits and vegetables in your diet, which are rich in antioxidants, vitamins, and minerals. In fact, recent research suggests that a vitamin-rich plant-based diet may lower the risk of prostate cancer. Try including cruciferous vegetables, such as broccoli, cabbage, and kale, which are rich in beta carotene.

Average Psa Test Doubling Time

Another red flag. This calculation denotes the time it takes your PSA values to double.

Therefore it may signify the aggressiveness of any prostate abnormalities, whether it’s an enlarged prostate, prostatitis, or prostate cancer.

If your average PSA readings double in less than three years your doctor will most likely order a biopsy, to look in to the problem further and discuss possible prostate cancer treatment options.

The Difference Between Prostate Cancer And Bph

He is an associate professor of clinical medicine at Weill Cornell Medical College and attending physician in the Department of Hematology and Oncology at the New York Presbyterian Weill Cornell Medical Center.

Both prostate cancer and benign prostatic hyperplasia can cause an enlarged prostate, but beyond causing common symptoms, the similarities end there.

During your yearly physical, your doctor might do a rectal exam or request you get a blood test to check your prostate-specific antigen level checked. If your prostate is enlarged or your PSA test comes back high, your doctor may do a biopsy to determine if your abnormal results are caused by prostate cancer or BPH. Here’s what you need to know about the two conditions and their similarities and differences.

When Should I Have My Psa Levels Tested

The first thing to do is talk to your doctor about the pros and cons of prostate cancer screening before you decide whether to be tested. Donât get tested until you have that talk. Opinions differ about when you should do that.

The American Cancer Society says to get tested at age:

  • 40 or 45 if youâre at high risk
  • 50 if youâre at average risk

The American Urological Association suggests:

  • Under 40: No screening
  • 40 to 54: No screening if youâre at average risk. If youâre at a high risk, you and your doctor can decide.
  • 55 to 69: Screening if your doctor suggests
  • Over 70 or less than a 10-15 year life expectancy: No screening

The U.S. Preventive Services Task Force says:

If your doctor thinks you might have prostate cancer based on either a PSA level or a rectal exam, a biopsy is the next step. This is a test where the doctor takes a small amount of tissue from your prostate and sends it to a lab for tests. Itâs the only way to be sure you have cancer.
