Invasive Ductal Carcinoma
Invasive Ductal Carcinoma (IDC), also known as infiltrating ductal carcinoma, is a type of breast cancer that occurs when abnormal cells growing in the lining of the milk ducts change and invade breast tissue beyond the walls of the duct. The cancer cells then spread to the lymph nodes or bloodstream and further into other organs and areas in the body. This leads to metastatic breast cancer.
Causes of Invasive Ductal Carcinoma
It is not quite known what the causes of IDC are, but specialists have identified certain risks associated with it. These include:
Symptoms of IDC
Common symptoms of Invasive Ductal Carcinoma include:
Diagnosis of Invasive Ductal Carcinoma
To make a definitive diagnosis, the specialist will perform a physical exam by manually examining the patient’s breast to detect a lump. If the doctor feels the presence of a lump or any thickening, he/she may recommend the following tests to rule in/out IDC:
Digital mammography: This is an improved method for breast imaging usually performed much like a regular mammogram. It is more advanced because it is the most suitable test for detecting cancer in younger patients who normally have dense breast tissue.
Breast ultrasound: The procedure uses sound waves to examine breast tissue. During the procedure, the doctor can gauge the patient’s blood flow. Since ultrasound doesn’t use radiation, it is safe for examining expectant patients
Breast Magnetic Resonance Imaging (MRI): It uses a large magnet, radio waves, and a computer to detect small breast lesions. MRI is more useful in examining patients with a high risk of breast cancer.
Fine Needle Biopsy: During the procedure doctor takes a sample of breast tissue from a suspected area, and sends it to the lab for further evaluation under a microscope.
Staging workup: This is a procedure that helps the doctor to determine how far the cancer cells have spread to the lymph nodes or to the bloodstream and other parts of the body.
Treatment of Invasive Ductal Carcinoma
Treatment of invasive carcinoma is based on the following factors:
