Acting as judge, jury and executioner against the myriad microscopic hazards that bombard us, the immune system’s diverse army of white blood cells patrols the body. Yet even these protective cells are at risk of cancer. When white blood cell (T and B lymphocyte) cancers arise in tissues such as lymph glands and spleen, they form lymphomas. Here PET scans highlight lymphomas in white (left) and demonstrate their eviction after successful chemotherapy (right; the normal bladder appears as a white sphere in both). Lymphomas, like the cells from which they arise, are highly nuanced. Some are curable while others prove slowly or rapidly fatal. Conventional treatments: chemotherapy, radiotherapy, stem cell transplants and targetted antibodies; aren’t necessarily tailored to the subtleties of each tumour. Lymphoma gene expression profiling is now helping clinicians to deliver more personalised treatment options.

BPoD stands for Biomedical Picture of the Day. Managed by the MRC Laboratory of Medical Sciences until Jul 2023, it is now run independently by a dedicated team of scientists and writers. The website aims to engage everyone, young and old, in the wonders of biology, and its influence on medicine. The ever-growing archive of more than 4000 research images documents over a decade of progress. Explore the collection and see what you discover. Images are kindly provided for inclusion on this website through the generosity of scientists across the globe.
BPoD is also available in Catalan at www.bpod.cat with translations by the University of Valencia.
