Different Types of Fibroadenoma
There are several types and subtypes of fibroadenomas. The majority, ranging from 60 to 90 percent, fall under the category of “simple” fibroadenomas. These are characterized by their uniformity and typically measure around one to three centimeters or 0.4 to 1.2 inches in size.
Another type is known as juvenile fibroadenomas, which primarily affect adolescents between the ages of ten and 18. These fibroadenomas tend to grow rapidly but often resolve on their own without causing any complications.
Complex fibroadenomas, on the other hand, have a mixed composition when observed under a microscope. They are characterized by the presence of both calcifications and cysts. Complex fibroadenomas are more commonly found in individuals over the age of 40.
Giant Fibroadenoma
Giant Fibroadenoma, also known as GFA, refers to a lump that exceeds five centimeters (approximately two inches) in size. In some cases, these lumps can grow to such an extent that they cause deformity in the breast or result in visible asymmetry. A study conducted on patients with GFA revealed that nearly two-thirds of them had an average tumor size of around 10.2 centimeters (four inches) and weighed approximately 7.2 ounces. Although these tumors are usually benign at this stage, the only available treatment option is their removal.
