Scientists look to 3-D printing to help treat cancer

British scientists have developed a new use for 3-D printing, putting it to work to create personalized replica models of cancerous parts of the body to allow doctors to target tumours more precisely. The initiative is the latest example of medicine harnessing the rapidly emerging technology, which has already been used to manufacture some medical implants. The new cancer work involves printing 3-D “phantoms” of tumours and organs based on CT scans taken of patients during treatment. These plastic moulds can be filled with liquid, allowing experts to see in detail the flow of so-called radiopharmaceuticals. Read more here.
