Types Of Breast Cancer

What Are The Types Of Breast Cancer?

Breast cancer is categorized into different types depending on the extent of spreading of the disease and the seriousness of complications. The specific types of Breast cancer originating in inner tissue layers are suffixed with the term “carcinoma”. Depending on the extent of spread, the site/source of growth and the responsiveness to hormonal treatment, breast cancer may be classified as below:

  • Ductal carcinoma in situ (DCIS): This is the most harmless and common type of breast cancer which is non-invasive. It starts in a milk duct and is curable. Although this type of stage is not in a spreading mode, the nature of cells is malignant which needs medical treatment. If left untreated, DCIS would turn itself harmful to the organ.

  • Invasive Ductal Carcinoma (IDC): This type is the most common breast cancer and more harmful than the earlier variety DCIS, since the malignant cells originating milk duct break through the duct wall and ramify into the surrounding tissues, with a potential danger to spread other adjacent organs of the body. Invasive Ductal Carcinoma is further divided into sub-categories based on the nature of tumors it forms.

  • Lobular Carcinoma in situ (LCIS): This type is also known as Lobular Neoplasia originating in lactating lobules. In spite of the word “carcinoma” present in its title, the disease is not considered as breast cancer but has a harmful potential into developing into breast cancer.

  • Inflammatory Breast Cancer (IBC): The main features of this type are redness and swelling of the breast. Patients can sense the heaviness, increased warmth and tenderness of the affected breast. The skin of the affected breast loses its softness and the external surface becomes thick and rough, akin to rugged rind of an orange. It is not detectable in the tests of mammogram.

    Types Of Breast Cancer

  • Paget disease of the breast (or Nipple): This variety of breast cancer causes itchiness, hardening of skin on the nipple and also on the circular dark patch around the nipple called “aerola”. There is a possibility of developing one or more cancerous tumors in & around the nipple or in the same breast. Oozing out of yellow or bloody fluid from the nipple of the affected breast may also be noticed.

  • Metaplastic breast cancer: The name “metaplastic” itself indicates the invasiveness of the cancer that originates in a milk duct forming bigger tumours. The appearance of cancerous cells is different from their typical counterparts in other categories, making it difficult to identify and finalize the method of treatment.

  • Angiosarcoma of breast: This occurs as a rare malignant tumor arising in endothelial layers in vascular channels. It is more likely to spread through blood vessel network rather than lymph system. It is not identifiable in prognosis and the sole method of treatment is mastectomy or resection. Chemotherapy is selectively resorted to in such cases.
