tubular, medullary, mucinous, papillary, and adenocystic. These cancers are rare and the prognosis for women who have them is excellent.An in situ cancer is one that is confined to its site and shows no tendency of spreading. It can be detected only through a mammogram. An in situ breast cancer appears in the ducts or lobules.An in situ cancer of the duct is often referred to as DCIS.DCIS cancers can be detected very earlyLCIS (lobular neoplasm) is most common in pre-menopausal women.If LCIS appears in one breast, it will likely appear in the other. Therefore the other breast must be closely watchedAn infiltrating, or invasive, cancer is one in which the cancer spreads to tissue surrounding the ducts or lobules. This type of cancer can be detected by physical exams.An invasive cancer is not one that has spread to other parts of the body, but only to other breast tissue.Infiltrating cancer of the duct is the most common form of breast cancer. It produces a lump larger than that produced by cancer in the center of the breast, thus making detection easier. Warning signs include nipple retraction, nipple discharge, and skin changes.Infiltrating cancer of the lobules accounts for about fifteen percent of cases of breast cancer. It is harder to detect on a mammogram and so will be larger when detected. The tumor itself is also softer, more a thickening than a lump. If present in one breast, might be present in other one as well.There is a condition called Pagets Disease of the breast whose presence usually indicates underlying in situ or invasive ductal cancer. The symptoms are oozing from the nipple, scaliness, or skin hardening. This condition is very rare.There is a rare condition called Cystosarcoma phyllode which can be cancerous usually appears only in women in their 30s or 40s. When cancerous, it usually does not spread to other parts of the body, but may spread to other parts of the breast and tends to recur. Removal of surrounding...
