There’s no “good” cancer, but some are certainly worse than others when it comes to prognosis. Pancreatic cancer, for example, has a dismal survival rate. It’s inoperable in many cases, and in general it’s hard to deliver chemo to the tumor because its internal pressure keeps drugs at bay.
Researchers have been devising strategies to concentrate chemo in the most recalcitrant tumors, from injecting drugs directly into tumors themselves to directing chemo-coated magnetic particles to the site. The latest takes some of these ideas a step further while using existing drugs, a time-saving step. It comes in the form of a device that stores chemo and produces electric fields that carry the drugs directly into the tumor. Because many existing drugs are polar molecules, they are carried along with the electric current.
