	Cancer
		Rather, evidence is accumulating that cancers arise in precursor cells — stem cells or "progenitor cells" — of the tissue: cells that are dividing by mitosis producing daughter cells that are not yet fully differentiated.
		Aneuploidy is one of the hallmarks of cancer cells suggesting that failure of the spindle checkpoint is a major step in the conversion of a normal cell into a cancerous one.
		A single cell — perhaps an adult stem cell or progenitor cell — in a tissue suffers a mutation (red line) in a gene involved in the cell cycle, e.g., an oncogene or tumor suppressor gene.

		Cancer cells often travel to other parts of the body where they begin to grow and replace normal tissue.
		When cells from a cancer like breast cancer spread to another organ like the liver, the cancer is still called breast cancer, not liver cancer.

	The cancer cell
		Cancer cells are different to normal cells in several ways.
		So the cancer cell keeps on doubling, regardless of the damage the extra cells cause to the part of the body where the cancer is growing.
		Cancer cells can lose the molecules on their surface that keep normal cells in the right place.

		A Mixture of Epithelioid and Sarcomatoid Cancer Cells
		Because biphasic mesothelioma cancer patients have two very different mesothelioma cellular types associated with their disease, it can be an easier form of cancer to diagnose than either sarcomatoid or epithelioid (two cellular types that can be confused with a variety of other cancers).

	PA-04-035: CIRCULATING CELLS IN CANCER DETECTION
		Enrichment will allow exfoliated cells and subcellular molecules, for example from urine, to be used for genomic, proteomic, and epigenomic analyses that may lead to improvements in the detection of bladder cancer through measurements of alterations in expressed genes, peptide profiles, and epigenetic markers.
		With the advent of PCR-based detection of DNA from rare neoplastic cells in body fluids, mutations have been detected in ras genes from the stools of patients with colorectal cancer, in p53 from the urine of patients with bladder cancer, and in p53 genes in the sputum of patients with lung cancer.
		However, the detection of abnormal exfoliated cells, for instance, cancer cells by routine cytopathological examination may be limited because the number of abnormal cells may be very small compared to the number of normal cells, is difficult.

	Defining Signatures of Cancer Cells (Site not responding. Last check: )
		All cell types, depending on their functions, have unique, identifiable signatures or special characteristics such as which genes are active and what proteins or other cellular products are manufactured by the cell.
		Cancers of the urinary tract may be signaled by cancer cells that are "shed" in the urine.
		Generate a complete catalog of the distinguishing molecular signatures of normal, pre-cancerous, and cancerous cells; at all stages; in all tissues, and use the catalog to develop diagnostic techniques for the earliest detection of pre-cancerous lesions and cancers, develop signature-based therapies, and identify subsets of patients with different prognoses to predict therapeutic response.

	Epithelioid Mesothelioma Cancer - Mesothelioma Cancer Cells
		Epithelioid mesothelioma is the most common form of mesothelioma and accounts for 50 to 70% of the mesothelioma cancer cells.
		For example, epithelial cells are found in the skin, which separates the outside of the body from the inside of the body.
		Carcinoma, however, is a type of cancer that originates in the epithelium and adenocarcinoma is a special type of carcinoma that originates in the lining or inner epithelium of an organ.

	What Is Cancer?
		Cancer is actually a group of many related diseases that all have to do with cells.
		Cells are the very small units that make up all living things, including the human body.
		Sometimes cancer cells break away from the original tumor and travel to other areas of the body, where they keep growing and can go on to form new tumors.

	Sarcomatoid Mesothelioma Cancer - Mesothelioma Cancer Cells
		These cells are typically oval shaped, but more irregular, and with the nucleus not as clearly visible under an electron microscope as the nuclei of the epithelioid mesothelioma cancer cells.
		Although sarcomatoid cancer appears in other parts of the body, such as the kidney, sarcomatoid cancer is relatively rare in the lungs.
		In these cases, the pathologist must be careful to compare the appearance and staining of the cells, along with the overall appearance (localized versus diffuse pleural-based mass) and regularity of the tumor when making a definitive diagnosis of malignant mesothelioma.

	Defining the Signatures of Cancer Cells: Detection and Diagnosis, Scientific Priorities for Cancer Research, Plans and ... (Site not responding. Last check: )
		We have learned that during the transformation of a normal cell to a cancer cell, the signature changes, and that change becomes a signal of the presence of cancer.
		For example, tobacco-induced molecular changes in the mouth may predict the risk of developing lung cancer, and cancers of the urinary tract may be signaled by cancer cells that are "shed" in the urine.
		By assessing the meaning of individual changes in the cell's signature, we will be able to determine which cancers are most likely to progress and which are less likely to do so – a dilemma that confronts, for example, doctors treating patients with prostate cancer – thereby avoiding the consequences of unnecessary treatment.

	CNN.com - Study: Microbeams have big impact on cancer cells - Dec. 2, 2003
		Scientists at Britain's Cancer Research UK charity have dubbed it the "bystander effect" because the cancer cells zapped by the microbeams not only die but send out suicide signals to other abnormal cells, telling them to self destruct.
		Prise and his colleagues, who reported their findings in the journal Cancer Research, tested microbeams in the laboratory on brain cancer cells that were highly resistant to conventional radiotherapy.
		An estimated 50 percent of patients diagnosed with cancer would benefit from radiotherapy, which kills cancerous cells with tight beams or radiation aimed at specific areas of the body.

	STEM CELLS' REPAIR SKILLS MIGHT BE LINK TO CANCER
		Johns Hopkins researchers say there is growing evidence that stem cells gone awry in their efforts to repair tissue damage could help explain why long-term irritation, such as from alcohol or heartburn, can create a breeding ground for certain cancers.
		Over the last 10 years, researchers have found examples of these so-called cancer stem cells -- the cells within a tumor that are capable of regrowing the tumor -- in certain malignancies of the blood, breast and brain.
		"Cancers associated with chronic irritation may be a good setting in which to determine whether stem cells are the starting place of tumors," says Phil Beachy, Ph.D., professor of molecular biology and genetics in Hopkins' Institute for Basic Biomedical Sciences and a Howard Hughes Medical Institute investigator.

		As a result, students might perceive cancer as a group of foreign cells that are "invading" their normal cells, instead of knowing that cancer cells are simply normal body cells that have mutated.
		Students might also be unaware of the fact that all cells in every human being have the potential to become cancerous.
		Thus, students might think that cancer is a disease that you "catch" from others and the environment.

		In the July issue of Cancer Cell, the scientists explain how cancer tumor cells attach themselves to a protein on the surface of cells lining blood vessel walls.
		Wang speculated that if jagged1 is not secreted but found on the surface of tumor cells, then perhaps HGF gets jagged1 levels to increase, and that prompts a connection between the tumor and endothelial cells.
		Wang said he found it interesting that although much research has looked at cancer cells' secretion of proteins to form blood vessels, notch's function in cancer angiogenesis has not gotten the same attention.
