What is a Hyalinized fibroadenoma?

What is a Hyalinized fibroadenoma?

Fibroadenomas arise from the lobular stroma of the terminal duct lobular unit. They are a proliferation of epithelial and stromal components, likely related to estrogen. Over time, if left in situ, they undergo hyalinization of the stromal component with regression of the epithelial component.

What is borderline breast cancer?

Phyllodes (fil-oy-deez) tumors are a rare form of breast tumor; they can be benign (not cancerous), malignant (cancerous), or borderline (having characteristics of both). Phyllodes tumors account for fewer than 1% of all breast cancers.

Can fibroadenomas be mistaken for cancer?

While these changes in the breast tissue are very small, they may show up on mammograms as calcifications and can make lumps. Usually a biopsy is needed to rule out cancer. In addition, because the condition can be mistaken for cancer, the lumps are usually removed through surgical biopsy.

What is considered a fast growing breast tumor?

Phyllodes tumors tend to grow quickly, within a period of weeks or months, to a size of 2-3 cm or sometimes larger. This rapid growth does not automatically mean the phyllodes tumor is malignant; benign tumors can grow quickly, too. The lump is usually not painful.

Are fibroadenomas painful?

Usually, fibroadenomas are not painful. However, they can be uncomfortable or very sensitive to touch. Often women find that their fibroadenoma gets tender in the days before their period. Pushing or prodding at the lump can also make it tender.

Do breast fibroadenomas need to be removed?

Many doctors recommend removing fibroadenomas, especially if they keep growing or change the shape of the breast, to make sure that cancer is not causing the changes. Sometimes these tumors stop growing or even shrink on their own, without any treatment.
