The medical profession has experienced much difficulty and frustration in detecting and treating ovarian cancer, but researchers at the Yale School of Medicine, Connecticut, believe they have made a major breakthrough. They say eliminating cancer stem cells (CSCs) within a tumor could hold the key to successful treatments.  Read More

Blood vessels that supply tumors are more porous than normal vessels, makes nanoscale drug delivery systems a particularly attractive prospect. If properly engineered, nanoparticles can in fact get inside a tumor, targeting it precisely and allowing much higher drug dosages as they reduce side effects to a minimum. Two recent studies featured in the latest issue of the journal Nature Materials specifically address these issues and give us promising leads in the fight against cancer.  Read More

The IsoFlow Isolation Catheter in action.

A Silicon Valley entrepreneur, after watching helplessly through his sister's painful and terminal battle with cancer, has spent the last 9 years working on a system that lets doctors cut off blood flow to tumors, isolating them from the rest of the body and allowing the injection of a targeted dose of high intensity chemotherapy. Since the chemo drugs aren't let loose around the rest of the body, the usual devastating side-effects aren't an issue - and the drug dosage at the tumor site can be safely administered at a much higher concentration than usual. The IsoFlow Isolation Catheter has just received FDA marketing approval in the USA.  Read More

Nanotechnology is preoccupying science to the point where it's starting to seem unremarkable. But a group of researchers from the University of Washington has released findings that could profoundly improve the chances of surviving brain cancer. The team has developed a fluorescent nanoparticle that is capable of penetrating – for the first time – the blood-brain barrier without damaging it. The fluoro nanoparticle targets tumors using a derivative of scorpion venom and enables precise imaging of the size and location of cancerous growths. When the particles meet the tumor, they light up like Christmas.  Read More
