Invasive carcinoma NST is one of the most common types of all breast cancers, accounting for 55% of breast cancer incidence. [2] Of the invasive breast cancers, invasive carcinoma NST accounts for up to 75% of cases. [3] [4] It is also the most common form of breast cancer occurring in men, accounting for 85% of cases. [5] [6]
Ductal carcinoma in situ (DCIS), also known as intraductal carcinoma, is a pre-cancerous or non-invasive cancerous lesion of the breast. [1] [2] DCIS is classified as Stage 0. [3] It rarely produces symptoms or a breast lump that can be felt, typically being detected through screening mammography.
[9] Non-invasive apocrine carcinoma of the breast, i.e. apocrine ductal carcinoma in situ, is classified as a variant of ductal carcinoma in situ breast tumors. [9] Invasive carcinomas consisting of 10%–90% apocrine tumor tissue have been termed apocrine-like invasive carcinoma; these carcinomas sometime have estrogen receptor-positive [ 1 ...

Comedocarcinoma is a kind of breast cancer that demonstrates comedonecrosis, which is the central necrosis [1] of cancer cells within involved ducts. Comedocarcinomas are usually non-infiltrating and intraductal tumors, characterized as a comedo-type, high-grade ductal carcinoma in situ (DCIS).
Molecular classification of breast cancer from mRNA expression profiles. DNA microarrays have compared normal cells to breast cancer cells and found differences in the expression of hundreds of genes. Although the significance of many of those genetic differences is unknown, independent analyses by different research groups has found that ...
Mammography of non-invasive SPC generally shows round, circumscribed solid, well-defined masses while SPC with invasion may show a mass with irregular borders and/or architectural distortion. [3] Although usually localized to breast tissue, 3% to 5% of SPC tumors spread to nearby lymph nodes and ~2.8% metastasize to distant tissues. [20]
The prognosis is very positive since the cancer is at stage 0, meaning treatment will be less invasive and more effective, with a survival rate of 99%, according to the National Breast Cancer ...
