Types of breast cancer

There are different types of breast cancer and some are more common than others. Knowing your type can help you and your doctor make decisions on treatment and therapy.

Invasive or Infiltrating Ductal Carcinoma (IDC)

IDC is the most common type of breast cancer representing 78% of all malignancies. These lesions appear as stellate (star-like) or well-circumscribed (rounded) areas on mammograms. The stellate lesions generally have a poorer prognosis.

Invasive or Infiltrating Lobular Carcinoma (ILC)

Infiltrating lobular carcinoma is a type of breast cancer that usually appears as a subtle thickening in the upper-outer quadrant of the breast. This breast cancer type represents 5% of all diagnoses. Often positive for oestrogen and progesterone receptors, these tumours respond well to hormone therapy.

Inflammatory Breast Cancer (IBC)

Inflammatory breast cancer is a rare and very aggressive type of breast cancer that causes the lymph vessels in the skin of the breast to become blocked. This type of breast cancer is called “inflammatory” because the breast often looks swollen and red, or “inflamed.” According to Cancer Research UK, 1 to 4 out of every 100 diagnosed breast cancer are inflammatory breast cancer.
