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]
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 ...
Breast cancer incidence in women by age group. Breast cancer is the most common invasive cancer in women in most countries, accounting for 30% of cancer cases in women. [151] [113] In 2022, an estimated 2.3 million women were diagnosed with breast cancer, and 670,000 died of the disease. [151]
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. A defining feature of this ductal carcinoma is that it lacks the "specific differentiating features" of other types of ductal carcinomas.
The Triple Negative Breast Cancer Foundation ("TNBC Foundation") is a nonprofit organization dedicated to raising awareness of triple negative breast cancer.The foundation supports scientists and researchers in their efforts to determine the definitive causes of triple negative breast cancer so that effective detection, diagnosis, prevention, and treatment can be pursued and achieved.
In any case, the concentration of T 3 in the human blood plasma is about one-fortieth that of T 4. The half-life of T 3 is about 2.5 days. [3] The half-life of T 4 is about 6.5 days. [4] T 3 levels start to rise 45 minutes after administration and peak at about 2.5 hours.
Metastatic breast cancer, also referred to as metastases, advanced breast cancer, secondary tumors, secondaries or stage IV breast cancer, is a stage of breast cancer where the breast cancer cells have spread to distant sites beyond the axillary lymph nodes. There is no cure for metastatic breast cancer; [ 1] there is no stage after IV.
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 ...
