Choosing a Prostate Cancer Liquid Biopsy over a Tissue Biopsy

When it comes to determining the best level of care possible for prostate cancer treatment, getting the proper diagnosis using a prostate cancer liquid biopsy is essential right from the start. Without knowing what you may be dealing with from the beginning, it can be difficult to figure out which approaches to treatment can be most effective. With the rise of prostate cancer occurring in men and the difficulty that can arise with treatment, getting the best diagnosis possible is crucial. With improvements in methodology and technology over the years, there has also been controversy regarding what method may be best – a prostate cancer liquid biopsy, or a
traditional tissue biopsy.

Tissue Biopsy is the Standard

The tissue biopsy has long been the best standard method for analyzing tumors to determine their status. The removal of tissue gives doctors and pathologists direct tissue to analyze and evaluate so that they can determine the proper diagnosis for patients. The problem has always been that tissue biopsies can be very invasive, causing extra pain and hardship for patients. Tissue biopsies can also be impractical, particularly where cancer that has metastasized and spread to different areas is concerned. It is not practical to biopsy many areas around the body, looking at different tumors. Also, very often the tumors are located in difficult locations in the body, making it risky to insert a needle or perform surgery.

A Prostate Cancer Liquid Biopsy Alternative

Opting for a prostate cancer liquid biopsy can be a much better alternative for the doctor and the patient involved. The liquid biopsy is easier on the patient, typically requiring a blood test or urine test so that there are no invasive procedures involved. Doctors can then analyze the samples taken to get the information they need to perform a diagnosis and get the results they are seeking. The blood test lets doctors see the DNA of the tumor so that they can then decide which forms of treatment may be best for the patient. A cell-free DNA extraction kit is used for the procedure here’s a link to one  Having the ability to look at tumor DNA this way allows doctors to determine immunotherapies that will be most appropriate for the patient, mitigating potential risks to the patient that certain treatments may cause.

Less Risk, Less Expensive

The use of a prostate cancer liquid biopsy vs. tissue biopsy has other pluses. The testing used for a liquid biopsy is significantly less expensive for the procedures needed for a tissue biopsy. Tissue biopsy often involves surgical procedures or samples taken from bone, both of which can be quite costly. A simple liquid test is a blood draw or urinalysis. Tissue biopsies can also leave the patient at risk for infections, bleeding, and other complications, something that does not happen with a liquid biopsy.

The Future of a Biopsy

As time goes on and the technology and testing methods become more exact and developed, it is likely that the prostate cancer liquid biopsy will become more of the standard for use with patients. Current studies have already shown that these biopsies can be highly effective in detecting metastasized cancer in patients, and as the use and understanding of the methods continue to grow, a liquid biopsy will become faster, more effective, and less invasive alternative.
