Prostate cancer occurs in the prostate, the small walnut-shaped gland in men that produces the seminal fluid that nourishes and transports sperm, it is one of the most common types of cancer in men, it grows slowly and is initially confined to the prostate gland, where it may not cause serious harm. Some types of prostate cancer grow slowly and may need minimal or even no treatment, other types are aggressive and can spread quickly.
Researchers at Dundee University in Scotland have found a new ultrasound that is less invasive, more accurate and easily detect prostate cancer. Cancerous tissue feels harder than normal so an ultrasound is far better equipped to pick it up. Professor Ghulam Nabi, the university’s team leader for the project was able to show a stark difference in results between old technology and existing techniques such as MRI.
The new technology can detect cancers which MRI did not reveal, see with much greater accuracy what tissue is cancerous, where it is and what level of treatment it needs. Presently, there is no single test to detect prostate cancer. A combination of MRI scans, biopsies and physical examinations are carried out to determine if there are higher levels of prostate-specific antigen (PSA) in the blood. The new technology used by the Scottish university, known as shear wave elastrography (SWE), could help reduce prostate cancer-related fatality rates.
