Tumors can be either benign or malignant. However benign tumors are usually slow-growing extensive masses that compress rather than invade surrounding tissue. Benign tumors are not cancerous, i.e., cells do not extend to other parts of the body. But malignant tumors are cancerous. Cells in these tumors invade nearby tissues and extend to other parts of

LUNG CANCER STAGING CLASSIFICATION
Clinics in Chest Medicine, 1993In presenting the staging system, I recognize that in a given patient the total tumor burden cannot be precisely quantitated, and the balance between host defenses and the heterogeneity of the malignancy is not measurable. These and other complex interacting biological variables will influence the subsequent course of the disease.

Problems in the Classification of Breast Cancer
Radiologic Clinics of North America, 1983This article has sought to clarify the problems that beset the histologic classification of the numerous forms of breast cancer. Not only is classification itself difficult, but our lack of complete understanding of breast cancer often leaves us without criteria sufficiently clear to establish definite categories.

Classification of Pancreatic Cancer (Nonendocrine)
Mayo Clinic Proceedings, 1979From the records of 757 patients listed as having had pancreatic cancer at Memorial Hospital during the years 1949 through 1972, adequate clinical data and pathologic tissue were available for study in 508 patients. Review of these cases led to a histologic classification into 11 subcategories and one unclassified group.

Molecular Classification of Breast Cancer
PET Clinics, 2018Breast cancer is a heterogeneous disease, observed traditionally by morphology and protein expression but, more recently with the advent of modern molecular technologies, at the genomic and transcriptomic level. This review describes the association between the different molecular subtypes with the histologic subtypes of breast cancer alongside some of

The Classification and Staging of Cancer of the Larynx
The British Journal of Radiology, 1952The advantages and need for classification of cancer of the larynx are stated: anatomical and clinical classifications are discussed but preference is given to the topographical classification first developed at the Fondation Curie in Paris. A classification of this kind has been in use at the Royal Cancer Hospital and has proved satisfactory over a ...

A classification scheme for childhood cancer
International Journal of Cancer, 1987AbstractThe International Agency for Research on Cancer (IARC) is sponsoring a worldwide study of childhood cancer incidence. Cancers in children are highly specific and differ in many ways from cancers found in adults. Data for the international study will be presented according to the classification scheme described below which has been devised ...

Classification of Lung Cancer—to be Revised
JAMA: The Journal of the American Medical Association, 1967To the Editor:— The accuracy of lung cancer mortality data challenged inThe Journal( 198 :1374, 1966; 199 :674, 1967) may be considerably improved by the Eighth Revision of the International Classification of Causes of Death. The present nomenclature lists malignant neoplasm of bronchus and trachea and of lung, specified as primary (code No. 162), and

Molecular Classification of Breast Cancer
Surgical Pathology Clinics, 2012This article reviews the conceptual and practical implications of the intrinsic subtype classification of breast cancers and the limitations of this approach. It presents the most extensively validated gene expression assays proposed as predictors of clinical outcome and discusses their potential clinical utility and limitations.

Toward a molecular classification of cancer
Toxicology, 2010The diagnosis of cancer is typically made on the basis of clinical and histological criteria. However, molecular biology research over the past three decades has revealed that diagnoses based on clinical presentation and pathology evaluation are not always accurate.
