![]() “All that for prostate cancer?” asked one of the vet students, glancing over at my notes. ![]() Many treatments for prostate cancer work by blocking testosterone’s generation within the testicles – with no testosterone, the growth of the tumour slows. In health, the prostate gland stores semen and mature sperm it has strong muscular walls that squeeze during ejaculation.Įxposure to a lifetime of testosterone increases the growth of the gland as well as its susceptibility to cancers. One day I was revising prostate cancer: the appearance of its malignant cells under a microscope, the stages of its spread, the radiotherapy, brachytherapy (embedding of radioactive pellets into the tumour), and standard chemotherapies used to treat it. It was reassuring to see how much common ground there was between medicine for humans and medicine for animals. Sometimes I’d find myself at a desk opposite one of the vet students we’d glance at one another’s textbooks with curiosity, occasionally open at the same subjects – haematology, say, or orthopaedic surgery. The university library at my medical school was shared with students of veterinary medicine.
