The Nottingham prognostic index (NPI) is used to determine prognosis following surgery for breast cancer. [1][2] Its value is calculated using three pathological criteria: the size of the tumour; the number of involved lymph nodes; and the grade of the tumour. [1] It is calculated to select patients for adjuvant treatment.
Terminology. Invasive carcinoma NST is a type of breast cancer. It is one of the invasive breast cancers that originates from the breast ductal system, so that it is a type of ductal carcinoma.

Breast cancer classification divides breast cancer into categories according to different schemes criteria and serving a different purpose. The major categories are the histopathological type, the grade of the tumor, the stage of the tumor, and the expression of proteins and genes. As knowledge of cancer cell biology develops these ...
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.

[3] It rarely produces symptoms or a breast lump that can be felt, typically being detected through screening mammography. [4][5] It has been diagnosed in a significant ...
MammaPrint. MammaPrint is a prognostic and predictive diagnostic test for early stage breast cancer patients that assess the risk that a tumor will metastasize to other parts of the body. [1] It gives a binary result, high-risk or low-risk classification, and helps physicians determine whether or not a patient will benefit from chemotherapy.
Triple-negative breast cancer comprises 15–20% of all breast cancer cases [3] and affects more young women or women with a mutation in the BRCA1 gene than other breast cancers. [4] Triple-negative breast cancers comprise a very heterogeneous group of cancers. TNBC is the most challenging breast cancer type to treat. [5]
