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 .
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]
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]
Triple-negative breast cancer (up to 15% of cases) and inflammatory breast cancer (up to 5% of cases) are particularly aggressive and have relatively poor prognoses. [ 82 ] [ 83 ] Those with triple-negative breast cancer have an overall five-year survival rate of 77% – 91% for those whose tumors are confined to the breast; 12% for those with ...
Histopathologic types of breast cancer, with relative incidences and prognoses, with "invasive lobular carcinoma" at top right. Invasive lobular carcinoma (ILC) is breast cancer arising from the lobules of the mammary glands. [ 1] It accounts for 5–10% of invasive breast cancer. [ 2][ 3] Rare cases of this carcinoma have been diagnosed in men ...
T 3 is the more metabolically active hormone produced from T 4.T 4 is deiodinated by three deiodinase enzymes to produce the more-active triiodothyronine: . Type I present in liver, kidney, thyroid, and (to a lesser extent) pituitary; it accounts for 80% of the deiodination of T 4.
James Paget. Paget's disease of the breast (also known as mammary Paget's disease) is a rare skin change at the nipple nearly always associated with underlying breast cancer. [ 2] Paget's disease of the breast was first described by Sir James Paget in 1874. [ 3] The condition is an uncommon disease accounting for 1 to 4% of all breast cancers ...
Inflammatory breast cancer is a high-grade aneuploid cancer, with mutations and overexpression of p53, [ 13] high levels of E-cadherin and abnormal cadherin function. It is often regarded as a systemic cancer. A large number of IBC cases present as triple negative breast cancer (TNBC).
