Infiltrating duct carcinoma, also known as invasive ductal carcinoma, is a type of breast cancer that originates in the milk ducts and spreads beyond the ducts into the surrounding breast tissue. It is the most common type of breast cancer, accounting for approximately 70-80% of all cases.
In infiltrating duct carcinoma, cancer cells infiltrate and invade the breast tissue, forming a solid tumor. The tumor can vary in size and may or may not be palpable during physical examination. It is typically characterized by irregular borders and an uneven surface.
This type of breast cancer often presents as a painless lump, although it can also cause other symptoms such as nipple retraction or discharge, skin changes, or breast pain. Due to its invasive nature, infiltrating duct carcinoma has the potential to spread to the lymph nodes and other organs, leading to metastasis.
Diagnosis of infiltrating duct carcinoma is usually done through imaging techniques, such as mammography or ultrasound, followed by a biopsy to confirm the presence of cancer cells. Treatment options for this type of breast cancer may include surgery (lumpectomy or mastectomy), radiation therapy, chemotherapy, targeted therapy, or hormonal therapy, depending on the stage and characteristics of the cancer.
Early detection and timely treatment are crucial for a favorable prognosis in infiltrating duct carcinoma. However, the prognosis can vary depending on several factors, including the stage of cancer, the presence of hormone receptors, and the individual's overall health. Regular breast self-examinations, clinical breast examinations, and mammograms are essential for early detection and potential prevention of infiltrating duct carcinoma.
