D05: Carcinoma in situ of breast
Carcinoma in situ of the breast is a term that defines a group of non-invasive breast cancers. This condition occurs when abnormal cells are found in their place of origin, which, in this case, is the milk ducts or milk-producing glands of the breast. These cells have not spread or invaded other parts of the breast tissue. Since they remain inside their place of origin, these cancers are considered 'in situ' or 'in its original place'. Common symptoms may include a lump in the breast or underarm, change in breast size or shape, fluid leaking from the nipple, or altered skin on the breast or nipple. However, in many cases, this condition may not show any overt signs or symptoms. It's crucial to note that disease progression varies, with some cases remaining stable while others may evolve into invasive cancers over time. Therefore, regular screenings and follow-ups are essential for monitoring health status.
