Duct cancer, also known as ductal carcinoma, is a type of cancer that originates in the ducts of certain organs, predominantly the breast. It specifically refers to the abnormal and uncontrollable growth of malignant cells within the milk ducts of the breast.
In the context of breast cancer, duct cancer accounts for approximately 80% of all breast cancer cases. It typically begins as a small lump or mass within the milk duct, and if left untreated, has the potential to invade nearby tissues and spread to other parts of the body through the lymphatic system or bloodstream.
Symptoms of duct cancer may include a lump or thickening in the breast, changes in breast size or shape, nipple discharge (particularly if it is bloody), nipple inversion or retraction, skin dimpling or puckering, and redness or scaling of the nipple or breast skin.
Early detection of duct cancer is crucial in order to increase treatment success and improve prognosis. Diagnostic methods may include mammography, ultrasound, biopsy, and magnetic resonance imaging (MRI) scans. Treatment options typically involve surgery, such as lumpectomy or mastectomy, followed by radiation therapy, chemotherapy, targeted therapy, or hormone therapy, depending on individual factors such as tumor size, stage, and hormone receptor status.
Regular self-examinations, mammograms, and clinical breast examinations are important in the early detection and prevention of duct cancer in order to enhance survival rates and foster better outcomes.
