Prostate biopsy is a procedure in which small hollow needle-core samples are removed from a man's prostate gland to be examined for the presence of prostate cancer. It is typically performed when the result from a PSA blood test is high. [ 1 ]
The doctor uses ultrasound and X-ray pictures to make sure the seeds are in the right place. A special computer software program is used to make sure the prostate gland is completely covered by just the right dose of radiation (see Figure 4) to ensure that all cancer cells present in the prostate have been completely treated.

Clinical applications of PDT for prostate cancer have demonstrated potential benefits in terms of efficacy and safety, particularly for patients with localized, low to intermediate-risk tumors. PDT offers the advantage of targeting specific areas within the prostate, which can help preserve urinary and sexual functions that are often affected ...
Medical ultrasound includes diagnostic techniques (mainly imaging techniques) using ultrasound, as well as therapeutic applications of ultrasound. In diagnosis, it is used to create an image of internal body structures such as tendons, muscles, joints, blood vessels, and internal organs, to measure some characteristics (e.g., distances and velocities) or to generate an informative audible sound.
Transrectal biopsy is a biopsy procedure in which a sample of tissue is removed from the prostate using a thin needle that is inserted through the rectum and into the prostate. [1] Transrectal ultrasound (TRUS) is usually used to guide the needle. [2] [3] The sample is examined under a microscope to see if it contains cancer.
Transrectal ultrasonography, or TRUS in short, is a method of creating an image of organs in the pelvis, most commonly used to perform an ultrasound-guided needle biopsy evaluation of the prostate gland in men with elevated prostate-specific antigen or prostatic nodules on digital rectal exam.
A further transurethal method utilizes a robotically-controlled waterjet to remove prostate tissue. Visualization is provided by a combination of cystoscope and transrectal ultrasound methods. This procedure claims risk reduction advantages as a result of being heat free.
Prostate cancer was estimated to be the second leading cause of death by cancer in the US in 2018. [35] There are different methods used in screening for prostate cancer prostate biopsy, prostate-specific antigen testing (PSA), and digital rectal examination (DRE). In the DRE the examiner inserts a finger in the rectum of the patient and ...
