Headline: 'Targeted' cancer treatment effective in older patients

Researchers are looking into ways to "target" cancer cells. The treatment involves attaching radioactive particles to man-made versions of immune system proteins called antibodies. If proven effective, "targeting" cancer cells will cause less damage than radiotherapy, which can damage a patient's organs. Researchers hope the new treatment will help to extend the lives of elderly cancer patients.
