MammaPrint is based on the Amsterdam 70-gene breast cancer gene signature and uses formalin-fixed-paraffin-embedded (FFPE) or fresh tissue for microarray analysis. [3] It is a laboratory developed test (LDT) which falls into the class of In Vitro Diagnostic Multivariate Index Assays (IVDMIA).
A new study is raising fresh questions about the value of breast cancer screening in older women, finding that those 70 and older who underwent mammograms were more apt to be diagnosed with tumors ...
The American Cancer Society reports 5-year relative survival rates of over 70% for women with stage 0-III breast cancer with a 5-year relative survival rate close to 100% for women with stage 0 or stage I breast cancer. The 5-year relative survival rate drops to 22% for women with stage IV breast cancer. [3] In cancer types with high survival ...
Mucinous carcinoma of the breast is a form of mucinous carcinoma and a breast cancer type.

[2] Rare cases of this carcinoma have been diagnosed in men (see male breast cancer). [3]
Staging of breast cancer is one aspect of breast cancer classification that assists in making appropriate treatment choices, when considered along with other classification aspects such as estrogen receptor and progesterone receptor levels in the cancer tissue, the human epidermal growth factor receptor 2 status, menopausal status, and the ...

Staging breast cancer is the initial step to help physicians determine the most appropriate course of treatment. As of 2016, guidelines incorporated biologic factors, such as tumor grade, cellular proliferation rate, estrogen and progesterone receptor expression, human epidermal growth factor 2 (HER2) expression, and gene expression profiling into the staging system.
Metastatic breast cancer can be treated, sometimes for many years, but it cannot be cured. [2] Distant metastases are the cause of about 90% of deaths due to breast cancer. [3] Breast cancer can metastasize anywhere in body but primarily metastasizes to the bone, lungs, regional lymph nodes, liver and brain, with the most common site being the ...
