Uncommon Breast Cancer Type

For proper treatment, it is necessary to know the type of breast cancer you have developed. Causes, symptoms and treatment vary for different types of breast cancers, just as treatment may vary depending on the stage of your cancer.

Breast cancer can either be invasive or non-invasive. Non-invasive breast cancers, also called in situ breast cancers, have a very high survival rate. Cancer cells in non-invasive breast cancers are confined to the site where the cancer originated, and have not spread to other organs. The most common non-invasive breast cancer is Ductal Carcinoma In Situ or DCIS, which develops in the breasts’ milk ducts and does not metastasize. The best and easiest treatment for DCIS is mastectomy, and patients are cured fully, most of the times.

Metastasis occurs when the cancer cells do not remain in the site where they initially develop, but spread to other parts of the body and start malignant cell formation there. When this happens, the cancer is called Invasive breast cancer. The two commonest types of invasive breast cancer are Invasive Ductal Carcinoma and Invasive Lobular Carcinoma.

Invasive Ductal Carcinoma accounts for 70% to 80% of all breast cancer cases. Originating in the ducts of the breast, the cancer spreads outside the ductal lining and attacks the breast tissue. There is no certainty if the cancer cells remain confined to the breast or metastasize to other organs. Invasive Lobular Carcinoma, on the other hand, is characterized by cancer cells originating in milk-producing lobules of the breast and then spreading out the same way as in IDC. One typical attribute of ILC is that no distinct lump formation is necessary. The breast usually 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.

Here is why it is necessary that you know even about the rarer breast cancer types: Inflammatory breast cancer, however uncommon, develops very rapidly, and, within very few days, can reach a very advanced stage; by the time you seek medical advice, it might be too late to fully cure you.

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.

You should be well-informed about everything related to these cancers, that you know when a symptom suggests you might have breast cancer, when to seek medical advice, that the progress of your treatment is good or not, and all the measures necessary to ensure you stay healthy and get cured.
