Classification Of Breast Cancer By WHO
Classification Of Breast Cancer By WHO
SM. MOHABBOT HASAN
I have study hard on Who transcript on breast cancer and their all appendix and now sit to write on their idea. This information is very important to increase the rate of knowing about the classification of breast cancer. Histo pathologic classification relies upon characteristics seen upon lightweight research of diagnostic test specimens. The 3 most typical histo pathological varieties together represent some three-quarters of breast cancers:
Invasive ductal cancer - fifty fifth of breast cancers
Ductal cancer in place - 13%
Invasive lobe cancer - 5%
The overall 5-year survival rate for each invasive ductal cancer and invasive lobe cancer was some eighty fifth in 2003.[5] Ductal cancer in place, on the opposite hand, is in itself harmless, though if untreated some hour of those low grade DCIS lesions can become invasive over the course of forty years in follow-up.
WHO classification
The 2003 World Health Organization (WHO) classification of tumors of the breast[7] which incorporates benign (harmless) and malignant (cancerous) tumors, recommends the subsequent pathological types:
Invasive breast carcinomas
Invasive ductile cancer
Most area unit "not otherwise specified"
The remainder area unit given subtypes:
Mixed sort cancer
Pleomorphic cancer
Carcinoma with bone cell big cells
Carcinoma with choriocarcinoma options
Carcinoma with melanotic options
Invasive lobe cancer
Tubular cancer
Invasive cribriform cancer
Medullary cancer
Mucinous cancer and alternative tumours with voluminous glycoprotein
Mucinous cancer
Cystadenocarcinoma and columnar epithelial cell glycoprotein cancer
Signet ring cell cancer
Neuroendocrine tumours
Solid system cancer (characinoid of the breast)
Atypical tumour neoplasm
Small cell / oat cell cancer
Large cell system cancer
Invasive appendage cancer
Invasive micropapillary cancer
Apocrine cancer
Met plastic carcinomas
Pure animal tissue met plastic carcinomas
Squamous cell cancer
Adenocarcinoma with spindle cell metaplasia
Adenosquamous carcinomasukers
Mucoepidermoid cancer
Mixed epithelial/mesenchymal metaplastic carcinomas
(Other well-accepted subtypes of metaplastic duct gland cancer thought to possess clinical significance however not enclosed within the decade recent UN agency classification:
Matrix-producing cancer
Spindle cell cancer
Carcinosarcoma
Squamous cell cancer of duct gland origin
Metaplastic cancer with osteoclastic big cells)
Lipid-rich cancer
Secretory cancer
Oncocytic cancer
Adenoid cystic cancer
Acinic cell cancer
Glycogen-rich clear cell cancer
Sebaceous cancer
Inflammatory cancer
Bilateral breast cancer
Mesenchymal tumors (including sarcoma)
Hemangioma
Angiomatosis
Hemangiopericytoma
Pseudoangiomatous stromal dysplasia
Myofibroblastoma
Fibromatosis (aggressive)
Inflammatory myofibroblastic neoplasm
Lipoma
Angiolipoma
Granular cell growth
Neurofibroma
Schwannoma
Angiosarcoma
Liposarcoma
Rhabdomyosarcoma
Osteosarcoma
