Breast cancer can be of many types but some of these are extremely rare and are not found commonly. In some cases, breast tumors can be diagnosed as a combination of in situ and invasive cancer or a mixture of two or more types from among those mentioned below.
Types of Breast Cancer
Ductal Carcinoma In Situ
Ductal Carcinoma in situ, also referred to as intraductal carcinoma, is one of the most common types of breast cancer. Non invasive in nature, this type of cancerous growth develops within the ducts and does not spread to the adjoining areas and breast tissues.
Diagnosed with the help of a mammogram, DCIS accounts for over 20 percent of breast cancer cases and can be cured if diagnosed in its early stages.
Invasive Ductal Carcinoma
IDC is the most common type of breast cancer which begins in the milk ducts of the breasts and infiltrates through the walls of the duct, to spread into the fatty tissues present in the region of the breasts. Invasive Ductal Carcinoma can also spread to other parts of the body through the blood stream or lymphatic system. Over 80 percent of invasive breast cancers are IDCs.
Invasive (or infiltrating) Lobular Carcinoma
The milk producing globules, known as the lobules are the point of origination of Invasive Lobular Carcinoma. Just like IDC, this form of infiltrating breast cancer can metasize or spread to other portions of the body. 10 percent of all known invasive breast cancer cases are diagnosed as ILCs.
This type of breast cancer is hard to detect through a normal mammogram and requires other advanced means for diagnosis.
Less Common Types of Breast Cancer
Inflammatory Breast Cancer
Accounting for only 1-3 percent of all known cases of breast cancer, it does not reveal any tumor or single lump. It makes the breast skin and adjoining areas feel warm and look inflamed and red. Inflammatory Breast Cancer gives the skin of the breast a pitted and thick appearance, which makes it appear like the peel of an orange. These changes in the breast are linked with the blocking of the lymph vessels under the skin by cancerous cells. IBC results in the breasts becoming, firmer, larger, itchy or tender than before.
Triple-negative Breast Cancer
This type of breast cancer is often used to describe invasive cells which lack estrogen and progesterone receptors. This type of breast cancer is more commonly found in Afro-American and younger women.This very invasive type of breast cancer spreads at a much faster rate than the other known types of breast cancer.
Paget Disease of the Nipple
Starting in the ducts of the breast, this type of breast cancer first spreads to the nipple skin and then to other parts of the areola. Very rare and uncommon, Paget Disease accounts for only 1 percent of breast cancer cases and makes the skin appear scaly, crusted and red with instances of oozing or bleeding.
Phyllodes Tumor, Angiosarcama, Adenoid cystic (or adenocystic) carcinoma, Medullary, Mucinous or Papillary carcinoma and so forth are other types of breast cancers, which effect women globally.
