A pituitary tumour is a growth in your pituitary gland, a small organ in your brain that produces hormones influencing nearly every part of your body, including growth, blood pressure, and reproduction. Most of these tumours are noncancerous and grow slowly. Depending on their size and type, they can affect your health by disrupting your hormone levels, which might lead to symptoms like vision problems, fatigue, or changes in menstrual cycles for women. Treatment varies from monitoring to medication, surgery, or radiation, aimed at managing the tumour’s effects and restoring your hormone balance.
