Most cancer is still treated with surgery, chemotherapy and radiation. While these often do the job, doctors can’t always predict who will respond. And because chemo and radiation kill healthy cells, too, they can have debilitating side effects. But as scientists decode the DNA of tumors, they’re able to target cancer more precisely. Here’s the scoop on the latest treatments.

The new drugs are directed at specific genetic glitches that “drive” a person’s cancer. (It’s more of a laser-guided missile than an atomic bomb.) This allows doctors to target mutations in tumors rather than just in the organ of origin (breast or lung, for example).
