New Technique to Detect Cancer with Ultrasound

Recently, scientists have discovered a new technique to detect cancers using ultrasound.

Key Highlights

• The new method uses ultrasound to turn a small tissue into droplets released into the blood.
• These droplets contain molecules like RNA, DNA, and proteins that enable scientists to detect particular types of cancer.
• Ultrasound can generate high-energy waves that can detach small tissue fragments from potentially cancerous areas.
• Currently, cancer is diagnosed by biopsy, where a small tissue sample is extracted using a needle to confirm the presence and type of cancer through In vitro tests.

 

⇒ About Ultrasound

• It is a type of sound wave with a frequency higher than the upper limit of human hearing, typically above 20 kHz.
• Sound waves can create pictures of the inside of the body through Ultrasound imaging.

 

⇒ Applications of Ultrasound

• To examine the development of a fetus during pregnancy.
• To diagnose conditions affecting organs like the heart, liver, kidneys, and gallbladder. 
• To monitor blood flow through blood vessels (Doppler ultrasound).
