Resources about cancer

Cancer is a class of diseasescharacterized by uncontrolled celldivision and the ability of these cells to invade other tissues, either by direct growth into adjacent tissue (invasion) or by migration of cells to distant sites (metastasis). This unregulated growth is caused by a series of acquired or inherited mutations to DNAwithin cells, damaging geneticinformation that define the cell functions and removing normal control of cell division. These invasive tissues are said to be malignant. The word tumor("swelling" in Latin) refers to any mass of abnormal tissue, but may be either malignant (cancerous) or benign(noncancerous).

Cancer can cause many different symptoms, depending on the site and character of the malignancy and whether there is
metastasis(spread). A definitive diagnosis usually requires the microscopic examination of tissue in the form of a biopsy. Once diagnosed, cancer is usually treated with surgery, chemotherapyand/or radiation.

If untreated, most cancers eventually cause
death; cancer is one of the leading causes of death in developed countries. Most cancers can be treated and many cured, especially if treatment begins early. Many forms of cancer are associated with environmental factors that are avoidable. Smoking tobaccoleads to more cancers than any other environmental factor.
