What does the Detection and Diagnosis of Prostate Cancer Entail?
Like all other types of cancer, men with prostate cancer must get diagnosed to determine the root or origin of the cancerous cell growth. It is primarily because early detection can help the doctors in deciding and suggesting a suitable treatment regime. It also aids in curing the ailment efficiently and promptly.
As such, scientists have developed several methods to help diagnose prostate cancer. Let us see what they are.
Imaging
The two chief imaging methods utilized for prostate cancer detection include:
- Ultrasound: Transrectal ultrasound, employed during biopsies, uses sound waves sent from a probe in the patient’s rectum to receive an image of the unusual cell growth.
- Magnetic Resonance Imaging (MRI): Since 2011, MRIs have played a vital role in target identification for prostate biopsies. It has accurately and precisely detected clinically significant prostate cancer in 80% of men. Dynamic contrast-enhanced MRI and combined diffusion-weighted (DW) imaging help distinguish between malignant and benign prostate lesions. The merged images of MRI and DW, with an enhancement in the dynamic contrast, helps visualize areas of fast wash-out effect and low-intensity signal. These aid in cancer discovery as they are the carcinoma characteristics.
Biopsy
A biopsy helps considerably in prostate cancer diagnosis. During the process, a radiologist or urologist acquired tissue samples from the patient’s prostate by inserting a biopsy gun through the rectum or the perineum and removing special hollow-core needles in a matter of mere seconds.
Systematic biopsies can accurately detect up to 63% of cases of prostate cancer successfully. However, antibiotics are necessary to prevent further complications like sepsis, fever, and urinary tract infections.
Tumor Marker
Doctors can determine the origin of malignant cells of prostate cancer that have metastasized by staining the tissue samples for the presence of PSA.
Biochemical Diagnosis
Alkaline phosphatase levels are more elevated in metastasizing cells. Detection of the intensity of these levels can help in detecting carcinomas cells in the prostate gland.
Gleason Score
The Gleason grading system helps in evaluating the prediction of prostate cancer and guides the therapeutic process. It depends predominately on the appearance of the tumor. A high score indicates a worse prognosis and a higher possibility of mortality.
Advanced prostate cancer is arduous to cure. Nevertheless, doctors trust the use of Zytiga when the cells move to the other parts of the body. It interrupts the androgen-making process at a crucial step, stopping the spread of cancer cells.
