Will my pituitary tumour affect breastfeeding?
A prolactinoma is a non-cancerous tumour in the pituitary gland, a small gland located under the brain that produces hormones. A prolactinoma can cause a range of problems, including headaches, changes in vision, and an increased level of the hormone prolactin. Increased prolactin can cause infertility and irregular periods among other symptoms. During pregnancy, the tumour is usually stable, but some women need treatment if it is growing or causing symptoms. If there are no symptoms, breastfeeding with a prolactinoma is considered safe. The tumour can be treated with medication or surgery, but both can decrease a mother’s ability to produce milk.
