A drawing of ductal carcinoma in situ in the anatomical context of the whole breast A drawing of a breast duct containing ductal carcinoma in situ. Most of the women who develop DCIS do not experience any symptoms. The majority of cases (80-85%) are detected through screening mammography. The first signs and symptoms may appear if the cancer ...

The overall 5-year survival rate of lobular carcinoma in situ has been estimated to be 97%. [16] LCIS (lobular neoplasia is considered pre-cancerous) is an indicator (marker) identifying women with an increased risk of developing invasive breast cancer. This risk extends more than 20 years.
Papillary carcinomas of the breast (PCB), also termed malignant papillary carcinomas of the breast, are rare forms of the breast cancers. [1] The World Health Organization (2019) classified papillary neoplasms (i.e. benign or cancerous tumors) of the breast into 5 types: intraductal papilloma, papillary ductal carcinoma in situ (PDCIS), encapsulated papillary carcinoma (EPC), solid-papillary ...
Invasive carcinoma NST accounts for half of all breast cancer diagnoses in women and is the most common type of invasive breast cancer. It is also the most commonly diagnosed form of male breast cancer. Invasive carcinoma NST is classified by its microscopic, molecular, and genetic features.
The most severe cases of dysplasia are referred to as carcinoma in situ.
