Uncommon Breast Cancer Type

Breast cancer is not a dark subject; it encompasses various types according to their area of occurrence and activity. Knowing about all types is necessary for prevention, and even during the course of your treatment, so that you know how to take proper measures and care of yourself.

In situ or non-invasive breast cancers usually have a good prognosis. This type of cancer is characterized by cancer cells limited to the original cancer site, without any metastasis. Ductal Carcinoma In Situ (DCIS), cancer that originates in the milk ducts of the breast and remains there, is the commonest In Situ breast cancer. DCIS has a great survival rate, mastectomy curing almost all DCIS cases.

Invasive breast cancers are characterized by cancer spreading out to body parts other than the site in which the cancer originates. These cells usually enter the lymph vessels and blood vessels and travel to other body parts, where they develop malignant tumors. The two most common invasive breast cancer types are Invasive Ductal Carcinoma, which is also the commonest breast cancer type, and, Invasive Lobular Carcinoma.

Seventy to eighty percent of all breast cancer cases are those of Invasive Ductal Carcinoma. Formation of cancer cells in the milk ducts of the breasts, which break through the ducts and spread to surrounding breast tissues and other parts of the body, is called Invasive Ductal Carcinoma. When such cells start forming in the milk lobules, and not ducts, and spread out, it is called Invasive Lobular Carcinoma. A distinguishing feature is that a lump is not necessarily formed in ILC, and usually the breast thickens as a whole.

All forms of breast cancer do not originate in ducts or lobes. Breast tissues, fibrous connective tissues, blood vessels and lymph vessels can also be the originating site for breast cancer. It is also possible that the cancer does not start in the breast, but spreads to the breast from cancer cells of another cancer. However uncommon these types are, it's always good to be informed. Inflammatory breast cancer, Paget's disease of the breast, metaplastic breast cancer, angiosarcoma, osteosarcoma and adenoid cystic carcinoma are some uncommon types of breast cancer.

Even though these types are uncommon, they can be very aggressive, like Inflammatory breast cancer, which develops so rapidly that it can cause a lot of harm within a week. It is important to be well-versed with the symptoms and causes of each of these types.

Invasive breast cancers are usually graded according to the semblance of the breast tissue compared to a normal breast tissue. Grades have three levels, from acceptable to worst, progressively. Grading helps determining treatments required and the urgency with which they're required. Grade I means the cells still have some normalcy; Grade III means cells are functioning abnormally and are physiologically degraded.

As you can see, knowing about all types of cancers can help you recognizing symptoms early on and advise you on how to make your treatment more effective, along with giving you proper knowledge and information on your treatment.
