Breast cancer is the most common form of cancer in the UK. Often represented by a distinctive shade of hot pink, charities have invested millions to overcome the disease. This image demonstrates an important area of cancer research – understanding how tumours develop. Most breast cancers start in a cluster of cells known as mammary acini. Here, two clusters (stained red) can be seen interacting through long lines of collagen (stained green), a structural protein found throughout the body. Clusters that interact through collagen chains are more likely to disorganise than non-interacting clusters. Beautiful though it may be, this disorganisation may lead to the formation of a cancerous tumour. Research into the development and growth of tumours will help scientists to design better, more targeted treatments for patients, paving the way to a cancer-free future.
