Paget's disease of the nipple (PDN) is a rare form of breast cancer that affects the nipple and areola. It is characterized by redness, flaking, and/or itching of the nipple and areola. It can also cause changes in the size and shape of the nipple and areola.
PDN typically comes and goes in stages. In the early stages, symptoms may include redness, flaking, and/or itching of the nipple and areola, along with occasional discharge from the nipple. As the condition progresses, the nipple may become larger and the areola may become darker. The nipple may also become inverted or flattened. In the later stages, the symptoms may become more severe and may include pain, swelling, and a visible lump in the area.
Although PDN can come and go, it is important to note that if the condition is not properly treated, it can become more severe and lead to invasive breast cancer. Therefore, it is important to see a physician as soon as possible if any of the symptoms listed above are present. With early diagnosis and treatment, the prognosis for PDN is generally good.
