The following is a list of cancer types. Cancer is a group of diseases that involve abnormal increases in the number of cells, with the potential to invade or spread to other parts of the body. [1] Not all tumors or lumps are cancerous; benign tumors are not classified as being cancer because they do not spread to other parts of the body. [1]
Compared to malignant (cancerous) tumors, benign tumors generally have a slower growth rate. Benign tumors have relatively well differentiated cells. They are often surrounded by an outer surface (fibrous sheath of connective tissue) or stay contained within the epithelium. Common examples of benign tumors include moles and uterine fibroids.
Common sites for squamous metaplasia include the bladder and cervix. Smokers often exhibit squamous metaplasia in the linings of their airways. These changes don't signify a specific disease, but rather usually represent the body's response to stress or irritation. Vitamin A deficiency or overdose can also lead to squamous metaplasia. [1]
A leiomyoma, also known as a fibroid, is a benign smooth muscle tumor that very rarely becomes cancer (0.1%). They can occur in any organ, but the most common forms occur in the uterus, small bowel, and the esophagus. Polycythemia may occur due to increased erythropoietin production as part of a paraneoplastic syndrome.
Clinically, mild glycogenic acanthosis is a normal finding, and does not progress to esophageal cancer or to stricture. [4] It is not related to leukoplakia, and is not dysplastic or premalignant. It was originally thought to be associated with gastroesophageal reflux disease (GERD), but the association is not entirely clear. [2]
Gastrointestinal stromal tumors (GISTs) are the most common mesenchymal neoplasms of the gastrointestinal tract. GISTs arise in the smooth muscle pacemaker interstitial cell of Cajal, or similar cells. [2] They are defined as tumors whose behavior is driven by mutations in the KIT gene (85%), [2] PDGFRA gene (10%), [2] or BRAF kinase (rare).
Esophageal cancer is the sixth-most-common cancer in the world, and its incidence is increasing. [4] Some three to five males are affected for each female. [ 4 ] An "esophageal cancer belt", in which the incidence of esophageal squamous cell carcinoma (SCC) is more than a hundred times that of adjacent areas, extends from northeastern China ...
