Focused Ultrasound and Microbubbles Improve Chemotherapy Drug Delivery

Anticancer drugs stop the growth of cancer cells. However, they also affect the growth of normal cells of the body, like in the digestive tract and the hair, resulting in multiple complications. Attempts have been made in the recent times to direct the chemotherapy medications selectively to the cancerous tissues. This reduces the toxic effects of the drugs on normal tissues, and at the same time, increases their concentration in the cancers. Focused ultrasound may be effective in directing chemotherapy enclosed in special nanoparticles to cancer cells, thereby reducing its harmful effects on normal body cells.
