Biology CalyxCanines

Cancer is a group of diseases in which cells are aggressive (grow and divide without respect to normal limits), invasive (invade and destroy adjacent tissues), and sometimes metastatic (spread to other locations in the body).

 


Cancer cells may be immortal; that is, proliferate indefinitely in culture. Example: HeLa cells are cultured in laboratories around the world.

Cancer
Introduction
Cancer is the uncontrolled growth of cells (mitosis). It ultimately kills the organism.

Cancer cell
a cell that divides and reproduces abnormally with uncontrolled growth. This cell can break away and travel to other parts of the body and set up another site, referred to as metastasis.

Cancer
Cancer is a group of diseases characterized by uncontrolled cell growth. Cancer begins when a single cell mutates, resulting in a breakdown of the normal regulatory controls that keep cell division in check.

Cancer-Detecting Microchip May Work as Assay
A new technique for detecting proteins associated with prostate cancer may serve as a sensitive assay for this common killer and have wide applications beyond diagnostics as well.

Cancer
Disease(s) in which abnormal cells divide and grow unchecked. Cancer can spread from its original site to other parts of the body and can also be fatal if not treated adequately. [Talking Glossary]

Cancer is caused by somatic mutations (mutations in cells of the body) in genes that are responsible for controlling cell division. Usually this requires several mutations since the cellular controls all have backups. Cancer is clonal.

Oncogene: A gene in a tumor virus or in cancerous cells which, when transferred into other cells, can cause transformation (note that only certain cells are susceptible to transformation by any one oncogene).

Defects in apoptosis are associated with maintenance of the transformed state and cancer. Anti-apoptotic proteins include Bcl-2 and HSP families (see also caspase).
