neoplasm/cancer definition: new abnormal tissue that grows by excessive cellular division and proliferation more rapidly than normal and continues to grow after the stimuli that initiated the new growth cease; tumors perform no useful body function and may be benign or malignant; benign neoplasms are a noncancerous growth that does not invade nearby tissue or spread to other parts of the body; malignant neoplasms or cancer show a greater degree of anaplasia and have the properties of invasion and metastasis; neoplasm terms herein do not distinguish between benign or malignant states, use references listed to cover this concept.
Malignant Neoplasm definition: A tumor composed of atypical neoplastic, often pleomorphic cells that invade other tissues. Malignant neoplasms often metastasize to distant anatomic sites and may recur after excision. The most common malignant neoplasms are carcinomas (adenocarcinomas or squamous cell carcinomas), Hodgkin and non-Hodgkin lymphomas, leukemias, melanomas, and sarcomas.

Carcinogenesis definition: A pathological process in which normal cells are transformed into malignant cancer cells within a primary tumor. Metastasis occurs in advanced stage cancers, whereby cancer cells are released into the bloodstream and attach to sites distinct from the primary tumor, resulting in the formation of secondary tumors.
breast cancer definition: (brest KAN-ser) Cancer that forms in tissues of the breast, usually the ducts (tubes that carry milk to the nipple) and lobules (glands that make milk). It occurs in both men and women, although male breast cancer is rare.

Risk factors include country of birth, family history, menstrual and reproductive history, fibrocystic disease and epithelial hyperplasia, exogenous estrogens, contraceptive agents, and ionizing radiation. The vast majority of breast carcinomas are adenocarcinomas (ductal or lobular). Breast carcinoma spreads by direct invasion, by the lymphatic route, and by the blood vessel route. The most common site of lymph node involvement is the axilla.

Colon carcinoma is one of the most common malignancies in both males and females, and is especially common in North America and Europe. Grossly, most colon carcinomas are polypoid or ulcerating lesions. Microscopically, adenocarcinoma is the most frequently seen morphologic subtype. Prognosis depends on the stage of the disease (depth of invasion, metastasis to regional/distal lymph nodes or other anatomic sites). -- 2004

Atlas of Cancer Mortality in the United States definition: The NCI's Atlas of Cancer Mortality in the United States, 1950-94, shows the geographic patterns of cancer death rates in over 3,000 counties across the country over more than four decades. It contains the 254 color-coded maps (for about 40 cancers), that will make it easy for researchers and state health departments to identify places where high or low rates occur, and to uncover patterns of cancer that would escape notice if larger areas, such as states, were mapped. The atlas will not tell researchers why death rates are higher in certain localities than in others, but it will provide important clues for further in-depth studies into the causes and control of cancer.
Cancer Biology definition: The study of the origins, growth, and treatment of any of various types of malignant neoplasms, most of which invade surrounding tissues, may metastasize to several sites, and are likely to recur after attempted removal and to cause death of the patient unless adequately treated; especially, any such carcinoma or sarcoma, but in ordinary usage, especially the former.
Cancer Burden definition: A measure of the incidence of cancer within the population and an estimate of the financial, emotional, or social impact it creates. The burden of disease is not borne equally by all population groups in the United State.
Cancer Center definition: Facilities designated Cancer Centers generally conduct a combination of basic, population sciences, and clinical research, and are encouraged to stimulate collaborative research involving more than one field of study. Several of these centers conduct only laboratory research and do not provide patient care. The NCI-designated Cancer Centers that do provide patient care are also expected to conduct early-phase, innovative clinical trials and to participate in the NCI Cooperative Group Program.
Cancer Cluster definition: A geographic area displaying a higher-than-expected rate of cancer incidence.
Cancer Control definition: Integrated program having an objective of reducing risk, incidence, and mortality from cancer and to enhancing the quality of life for cancer survivors. Realized through an orderly sequence of measures from genetic, epidemiologic, behavioral, social, applied, and surveillance cancer research to the development and implementation of effective interventions, and monitor and analysis of cancer trends in all segments of the population.
Cancer Detection definition: The act of discovery of a malignant neoplasm, and after treatment, the discovery of minimal residual disease.
Cancer Etiology definition: Study of the causes and origins of cancer(s).

The repository has stringent guidelines regarding the standardized collection, handling, storage and documentation of biological specimens. These guidelines enable an extensive system for specimen storage that allows for the accurate establishment of disease incidences over long periods of time.
