Infiltrating ductal carcinoma

Infiltrating Ductal Carcinoma (IDC), also known as Invasive Ductal Carcinoma, is the most common type of breast cancer, accounting for about 80% of all breast cancer diagnoses. It is a type of cancer that begins in the milk ducts of the breast and then invades the surrounding breast tissue.

Overview

IDC can occur at any age, but it is most commonly diagnosed in women over the age of 55. It can also occur in men, although this is rare. The exact cause of IDC is unknown, but certain factors such as age, family history of breast cancer, and certain genetic mutations can increase the risk of developing this disease.

Symptoms

The symptoms of IDC can vary from person to person, but they often include a lump or thickening in the breast or underarm, changes in the size or shape of the breast, changes in the skin of the breast (such as dimpling or puckering), and nipple discharge that is not breast milk.

Diagnosis

The diagnosis of IDC typically involves a combination of physical examination, mammography, ultrasound, and biopsy. The biopsy, which involves removing a small sample of tissue for examination under a microscope, is the only definitive way to diagnose IDC.

Treatment

The treatment for IDC depends on the stage of the disease, the patient's overall health, and the patient's personal preferences. Treatment options may include surgery, radiation therapy, chemotherapy, hormone therapy, and targeted therapy.

Prognosis

The prognosis for IDC varies widely depending on the stage of the disease at diagnosis, the patient's overall health, and the effectiveness of the treatment. Early detection and treatment can significantly improve the prognosis.
