According to Cancer research UK, the symptoms an individual develops depend on if the tumour makes hormones or not.
Tumours that do not make hormones, known as non secreting, can affect your eyesight, due to the location of the gland itself.
Tumours that create hormones, known as secreting, are more complex depending on the type of hormone that is released.
The most common type of secreting tumour is known as a Prolactin-secreting tumour, which can cause:
- Loss of sex drive
- Disruption of monthly periods
- Difficulty getting an erection
- Increased milk production in the breasts of women
