Invasive Ductal Carcinoma is among the most common of all types of breast cancers. Every 8 of the 10 cases of breast cancer in women are that of Invasive Ductal Carcinoma. This type of breast cancer is also known as Infiltrating Ductal Carcinoma because it can infiltrate to other parts of the body.It is also the most common type of breast cancer diagnosed in men.
Invasive Ductal Carcinoma is the name given to the type of cancer that has infiltrated to the healthy breast tissues after having infected the milk ducts present in the breast. The term “invasive” relates to the invading nature of this cancer type while “Ductal” refers to the milk ducts from where this cancer originates. These ducts are responsible for carrying the milk to the nipples from the lobules that produce milk. “Carcinoma” is the medical name given to any cancer that affects the tissues covering a major organ which in this case is the breast. Because of its invasive nature, Invasive Ductal Carcinoma or IDC can start affecting the lymph nodes if not treated at an earlier stage.
Even though breast cancer is not limited to a particular age group, older women are more at risk for developing Invasive Ductal Carcinoma than young women. American Cancer Society notes that almost two-thirds of the patients of invasive breast cancer are women of ages older than 55. Cases of Invasive Ductal Carcinoma are observed in men as well.
Invasive Ductal Carcinoma does not exhibit many clear symptoms in the initial stages. You can however, feel a lump developing in your breast, which is the first sign of this type of invasive breast cancer. An abnormal finding on a mammogram is also among the indicators that can point towards the presence of IDC in a woman.
