We need new treatments that target all types of secondary breast cancer cells before they have the chance to grow into tumours wherever they may be in the body. Secondary breast cancer is currently a managed disease; there is no cure. This is because it is impossible to know if every breast cancer cell that has moved from the breast has been targeted and destroyed. Some tumour types are resistant to treatments that are currently available and resistance can also develop over time. Against Breast Cancer is working with expert scientists at the University of Oxfords Glycoprotein Therapeutic Laboratory to investigate how to target treatment to secondary cancers. This will enable cancer-destroying drugs to be delivered specifically to secondary tumours before they grow and symptoms are experienced.
