Fibroadenomas, also known as breast mice, are a type of non-serious breast tumour.[2] They often feel round, firm, and are easy to move within the breast.[2] They are typically up to 3 cm in size and are not painful.[2][3] In about 70% of cases they occur singularly.[1] They are not associated with breast cancer;[2] though may result in anxiety or unequal breast size.[1]
The cause is unknown.[1] They may become more noticeable during pregnancy or hormone replacement therapy and shrink following menopause.[2] They contain a mixture of connective and glandular tissue.[2] Diagnosis may be supported by examination, ultrasound, mammography, and needle biopsy.[3][1] It involves ruling out other types of breast lumps including breast cancer and phyllodes tumors.[3]
If there are no symptoms, no treatment beyond reassurance and follow-up is required.[3][1] In cases that are bothersome, removal by surgery or biopsy is an option.[3] Other techniques that are being looked at include cryoablation and high-intensity focused ultrasound (HIFU).[3] Fibroadenomas affect about 25% of women.[3] They most often begin between the age of 15 and 35 years.[3] The name breast mice refers to their high mobility within the breast.[1]
