Women with breast cancer that has spread to the bone could benefit from a new pill they can take at home. Bondronat helps to stop cancer from spreading into the bone, while also reducing pain and the risk of fracture. Up to 80% of women with advanced breast cancer will develop secondary bone cancer, and most have to visit hospital in order to receive treatment. This drug has fewer side-effects than its predecessor, a bigger pill that has been linked to gastric problems. The drug has also been shown to provide patients with up to two years pain relief. The pain caused by bone cancer is often severe and constant, and can be resistant to pain killers such as morphine.
