Is there only one type of breast cancer?

Breast cancer is not a single disease but rather encompasses various types that can differ significantly in their biological characteristics, histopathology, treatment responses, and prognoses. The most common types include invasive ductal carcinoma, which originates in the milk ducts, and invasive lobular carcinoma, arising in the lobules. Additionally, there are other subtypes, such as triple-negative breast cancer and hormone receptor-positive breast cancer, each with its own unique properties and treatment protocols.

Furthermore, breast cancer can also be classified based on genetic factors, histologic characteristics, and how the cancer behaves. This diversity highlights the importance of individualized treatment plans and the need for thorough understanding and research into the various types of breast cancer. Recognizing this variety underlines the complexity of breast cancer and reinforces that the statement claiming there is only one type is inaccurate.
