|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.
Journal Article is sometimes called a Scientific Article, a Peer-Reviewed Article, or a Scholarly Research Article. Together, journal articles in a particular field are often referred to as The Literature.
Journal articles are most often Primary Research Articles. However, they can also be Review Articles. These types of articles have different aims and requirements. Sometimes, an article describes a new tool or method.
Because articles in scientific journals are specific, meticulously cited and peer-reviewed, journal databases are the best place to look for information on previous research on your species. Without a background in the field, journal articles may be hard to understand - however, you do not need to understand an entire article to be able to get valuable information from it.
