'Encouraging signs' from new prostate therapy

A new prostate cancer treatment could provide more effective and targeted results:

  • A light beam of ultrasound heats up cancer cells in an area as big as a grain of rice to 80 degrees
  • The intensity of heat totally destroys the cancer cells
  • It cuts down on damage to healthy tissues and reduces side-effects
  • Treatment is known as HIFU (high-intensity focused ultrasound)
