Found Cancerous 40 times.

Displaying results 1 to 10.

1. Acridine orange
3,6-bis(dimethylamino)acridinium chloride. A toxic, fluorescing dye that stains DNA and RNA and is typically used to identify cancerous tumor cells. When it binds to double-stranded DNA , it fluoresces green; when it binds with the phosphate groups of single-stranded DNA or RNA , it fluoresces orange. The chemical also causes frameshift mutations.

2. Adenocarcinoma
A cancerous tumor originating in glandular tissue.

3. Apoptosis (programmed cell death)
Programed cell death as signalled by the nuclei in normally functioning human and animal cells when age or state of cell health and condition dictates. cancerous cells, however, are unable to experience the normal cell transduction or apoptosis-driven natural cell death process.

4. Benign
Refers to a tumor that is non-cancerous; its cells do not proliferate, nor do they invade surrounding tissues.

5. Benign prostatic hyperplasia (BPH)
Benign prostatic hyperplasia is a common, noncancerous condition of men above 50 years old (it affects about 30 to 50% of older men). The enlarged prostate (a walnut-sized gland at the base of the penis) obstructs the urethra (the small tube that carries urine from the bladder) and causes frequent urination.

6. Calcification
Calcification is the process of deposition of calcium salts. In the formation of bone this is a normal condition. In other organs, this could be an abnormal condition. Calcification of the aortic valve causes narrowing of the passage (aortic stenosis). Calcification of breast tissues should be investigated as there is a high potential of cancerous growth.

7. Carcinemia (cancerous cachexia) (adj.: carcinemic)
Debilitation and emaciation caused by advanced-stage cancer .

8. Carcinoembryonic antigen (CEA)
This is an antigen in blood which is elevated in certain cancers of epithelial origin, notably colon, breast, lung and stomach. CEA is a molecule expressed on surfaces of epithelial cells during embryogenesis but is later confined to only the apical surface. Its function is related to cell adhesions. Tumor formation is accompanied with elevated expression of CEA. Blood CEA levels is a tumor marker to detect the recurrence of cancer or residual activity of cancer after surgery. However, CEA is a non-specific marker of cancer, and may be elevated in noncancerous conditions such as cigarette smoking, ulcerative colitis, liver disease, and lung infection. Therefore, CEA is not useful as a screening test. (Normal levels of serum carcinoembryonic antigen are 0 to 2.5 ug/L.)

9. Carcinogenesis
The process of a normal cell becoming cancerous.

10. Carcinoids (gastrointestinal carcinoid tumors)
Yellow, cancerous tumor s of hormone-making cells in the gastrointestinal tract (specifically, they are classed as neuroendocrine or amine precursor uptake and decarboxylation tumors). They produce excess endocrine s such as kallikrein (an activator of bradykinin release) and serotonin . These tumors can be found in the intestine, stomach, or sometimes on the liver. In later stages, this type of cancer causes symptoms such as diarrhea, wheezing, heart murmurs, enlarged liver, and a dusky appearance to the skin. Carcinoids can be diagnosed with a urine test or with a CAT scan.
