Prostate cancer is a common cancer among men, and a prostate biopsy is often used as a diagnostic tool. However, many men may wonder how often prostate biopsies actually detect cancer. It is estimated that 75% of prostate biopsies are found to be non-cancerous. In other words, only 25% of prostate biopsies are found to be cancerous. However, false negatives can occur in 30-40% of cases, meaning that some men may have cancer even if the biopsy did not detect it. Understanding the accuracy of prostate biopsies can help men make informed decisions about their healthcare and treatment options.

What is a prostate biopsies?

A prostate biopsy is a medical procedure that involves taking a small sample of tissue from the prostate gland to be examined under a microscope. The procedure is often used to diagnose prostate cancer, a type of cancer that develops in the prostate gland, which is part of the male reproductive system. It is estimated that about 1 in 8 men will develop prostate cancer at some point in their lives, making it the second most common cancer in men after skin cancer.

REALLY, How accurate is a prostate biopsies?

Okay, surprisingly, it is a known fact among researchers and medical professionals that the prostate biopsy procedure has a false negative rate of up to 34% (which is quite high for a test that’s supposed to let you know whether you need to be worried about dying from cancer).

According to a medical research paper published by the Canadian Urological Association Journal, the doctors and researchers put 90 prostate cancer patients (of whom had been repeatedly tested to be positive for prostate cancer) to the test. Among the 90 patients, only 67.8% were tested positive under the 12-core prostate biopsy procedure.

Why is the prostate biopsy accuracy rate so low?

Sadly, early-stage prostate cancer is just generally not visible on ultrasound. So, if a biopsy comes back negative, it doesn’t rule out a diagnosis of prostate cancer since many tumors are missed during the first biopsy.

Are there more accurate ways to detect prostate cancer?

If you wanna know for sure if there’s cancer chillin’ inside your prostate gland, I’m afraid the most accurate way is to just yank that bad boy out and give it a good ol’ histopathological examination. But, let’s be real, that’s not exactly feasible for everyone. I mean, I don’t know about you, but I’m not too keen on the idea of someone going in and just snatching my gland out like it’s no big deal. So, instead, we just settle for the ol’ prostate biopsy – the second best option for figuring out if there’s some funky stuff going on down there.

How do I know if I am ACTUALLY okay after a negative prostate biopsy result?

So if you settle for prostate biopsy like most people and what your doctor would recommend, and the test comes back negative, generally, patients will undergo multiple repeat prostate biopsies (RPBx) to see if there’s any undetected prostate cancer.

According to a research paper published by the Asian Pacific Prostate Society and recorded in the National Library of Medicine, if a patient’s first biopsy result is negative, doctors recommend they get a PSA assessment and a digital rectal exam (DRE) once a year. After that, doctors will decide whether the patient needs another biopsy based on their risk level for prostate cancer. The risk level depends on the patient’s last test result, family medical history, living habits, etc.

During a repeat biopsy, the physician must either avoid previously biopsied tissue (in cases of prior negative biopsy) or target the same anatomical site for patients with non-diagnostic, atypical small acinar proliferations (ASAP).

What Are Symptoms of Prostate Cancer?

Despite its high prevalence, prostate cancer often does not show any symptoms in its early stages, making regular screening important for early detection. However, some common symptoms of prostate cancer may include difficulty urinating, frequent urination, blood in the urine or semen, and pain or stiffness in the lower back, hips, or upper thighs can also be symptoms of prostate cancer. In more advanced cases, prostate cancer can spread to other parts of the body, leading to additional symptoms such as unexplained weight loss, fatigue, and swelling in the legs.

Okay, we talked a lot about prostate biopsy, which essentially is to tell patients whether they have prostate cancer. However, what exactly could cause prostate cancer in the first place?

What Causes Prostate Cancer?

The exact causes of prostate cancer are still not fully understood, but certain risk factors have been identified, such as age, family history, and race. Prostate cancer is more common in men over the age of 50 and those with a family history of the disease. Additionally, African American men are more likely to develop prostate cancer and are also more likely to die from it.

How Is Prostate Cancer Diagnosed?

Prostate cancer can be diagnosed through a variety of methods, including a digital rectal exam, a prostate-specific antigen (PSA) blood test, and a prostate biopsy. The PSA blood test measures the level of a protein produced by the prostate gland and can help detect early signs of prostate cancer. However, the test is not always accurate and can produce false positives or false negatives. A digital rectal exam involves a doctor manually examining the prostate gland for any abnormalities, but this method is also not always reliable.

How Is Prostate Cancer Diagnosed?

A prostate biopsy is considered the most accurate method of diagnosing prostate cancer. During the procedure, a doctor inserts a thin needle into the prostate gland to extract a small sample of tissue, which is then examined under a microscope for any signs of cancerous cells. However, the biopsy has a 30-40% false negative rate, meaning that even if a man has prostate cancer, the biopsy may not detect it. This can lead to a delayed diagnosis and unnecessary stress and fear for the patient.

If prostate cancer is diagnosed, there are several treatment options available, depending on the stage and severity of the cancer. These may include surgery, radiation therapy, hormone therapy, chemotherapy, or a combination of these methods. The best treatment option will depend on the individual case and should be discussed with a doctor.

How to prevent prostate cancer?

Although some patients got prostate cancer due to family DNA, but there are ways to lower the chance of it happening. So listen up, fellas! If you want to keep your prostate gland happy and healthy, here are some tips:

  • Eat your veggies! That’s right, Mom was right all along. Leafy greens, broccoli, and tomatoes are all good for your prostate.
  • Get movin’! Exercise helps keep everything in your body running smoothly, including your prostate.
  • Skip the bacon cheeseburger and go for the salmon instead. Fatty foods can increase your risk of prostate cancer.
  • Quit smoking. I know it’s tough, but smoking increases your risk of prostate cancer (along with a bunch of other health problems). So, put down the cigarettes and pick up a healthier habit, like knitting.
  • Put down the beer and pick up a glass of water. Drinking too much alcohol can also increase your risk.
  • And finally, get regular check-ups with your doctor. They’ll keep an eye on things and catch any issues early on.

Remember, a healthy prostate is a happy prostate!
