A group of Scottish researchers made the news last year when they began 3D printing models of brain tumors and studying them to study the effects certain treatments had on the cancer cells. Now a team of scientists in New Zealand is doing something similar, starting with the most common type of cancer in women: breast cancer. Testing drugs on cells grown in lab environments isn't new, but cells cultured in 2D environments behave very differently from the ones that actually make up a three-dimensional tumor. By 3D printing tumors using actual cancer cells, researchers can get a better idea of how actual tumors might react to a certain drug.
