Carcinoma is a cancerous growth of surface tissues i.e. epithelial tissue of the digestive tract, skin, blood vessels, and various organs. Carcinoma cells tend to spread surrounding healthy tissues and give rise to secondary growth distant from the original tumour. The process of spreading cancer form one tissue to another is called as metastasis. In addition to the skin and digestive tract, carcinomas will develop in the reproductive tract, mucous membranes, lungs, and other internal organs and glands, including the liver, pancreas, thyroid, ovaries, and prostate. Cancers of the nervous system, blood, bone, and muscle are not carcinomas. The causal study on disease of the cancerous growth is referred to as Carcinoma pathology.
Scientific journal is a periodical publication intended to further progress of science, usually by reporting novel research. There are thousands of scientific journals in publication, and many more have been published at various points in the past. Most journals are highly specialized, although some of the oldest journals publish articles and scientific papers across a wide range of scientific fields. Scientific journals contain articles that are peer reviewed, to ensure that articles meet the journal's standards of quality, and scientific validity. The publication of the results of research is an essential part of the scientific method. If they are describing experiments or calculations, they must supply enough details that an independent researcher could repeat the experiment or calculation to verify the results. Each such journal article becomes part of the permanent scientific record.
