Abstract
<jats:p>Prostate cancer is the most common malignancy amongst people assigned male at birth in the UK. Survival with prostate cancer has improved due to screening programmes and prostate‐specific antigen testing, resulting in earlier less advanced diagnoses and advancements in treatment. Prostate cancer does not usually cause symptoms until the cancer grows and puts pressure on the urethra. Prostate cancer prevention recommendations include maintaining a healthy weight, being physically active and eating a healthy diet. Obesity is a known risk factor for prostate cancer and is associated with higher prostate cancer‐specific mortality. In patients newly diagnosed with prostate cancer, nutritional interventions can play a key role in optimising their health for treatment. Surgery is usually used in patients treated with curative intent. Hormone treatment may use antiandrogens, luteinising hormone‐releasing hormone agonists, and gonadotropin‐releasing hormone antagonists. Radiotherapy is often used with curative intent and may have serious side effects.</jats:p>
