Oxygen supply and demand in tumours are intricately linked with disease progression, particularly in hormone sensitive tissues such as the breast and prostate. At present, there are few non-invasive methods with which we can reveal the spatiotemporal distribution of this process non-invasively. In this talk, I will focus on the use of photoacoustic imaging to: track the formation of new blood vessels in tumours using the absorption of light by haemoglobin; and probe levels of oxidative stress in cancer cells using a targeted photoacoustic contrast agent. I will conclude with future perspectives on clinical translation of this emerging new technology.
