What is it?

There are many types of benign, non- cancerous, breast lumps or neoplasms. They are more common in women but can appear in men as well.
The two most common benign neoplasms are fibroadenoma and simple cyst.
A fibroadenoma is a solid, non-tender breast lump, most commonly found in younger women, between the age of 20 and 35, or in post-menopausal women taking hormonal therapy.
A simple cyst is a fluid filled cavity inside your breast, most commonly appearing in women aged 35 to 50.
In men, an abnormal benign growth of breast tissue is called gynecomastia – it is very common, especially in teenage boys and older men.
