  2. Gastrointestinal cancer - Wikipedia

    en.wikipedia.org/wiki/Gastrointestinal_cancer

    Cancer of the esophagus is often detected late inasmuch as there are typically no early symptoms. Nevertheless, if the cancer is caught soon enough, patients can have a five-year survival rate of 90% or above. By the time esophageal cancer is usually detected, though, it might have spread beyond the esophageal wall, and the survival rate drops ...

    en.wikipedia.org/wiki/Leukoplakia

    The white lesion may be seen during cystoscopy, where it appears as a whitish-gray or yellow lesion, on a background of inflamed urothelium and there may be floating debris in the bladder. Leukoplakia of the bladder may undergo cancerous changes, so biopsy and long term follow up are usually indicated. [26]

  4. Papillary urothelial neoplasm of low malignant potential

    en.wikipedia.org/wiki/Papillary_urothelial...

    Delayed presentation with recurrent low-grade urothelial carcinoma is an unusual entity and potential mechanism of traumatic implantation should be considered. Characteristically low-grade tumors are resistant to systemic chemotherapy and curative-intent surgical resection of the tumor should be considered. [citation needed]

    About 70% occur in the stomach, 20% in the small intestine and less than 10% in the esophagus. Small tumors are generally not aggressive, especially when cell division rate is slow. GIST tumors commonly metastasize to the liver (in 28% of cases) and/or to the greater omentum, lesser omentum, or mesentery (in 30% of cases). Less common areas of ...

  6. List of cancer types - Wikipedia

    en.wikipedia.org/wiki/List_of_cancer_types

    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]

  7. Inflammatory fibroid polyp - Wikipedia

    en.wikipedia.org/wiki/Inflammatory_fibroid_polyp

    The inflammatory fibroid polyp is a benign lesion whose cause is unknown; [13] some reports attribute its genesis to myofibroblasts, [16] while others propose vascular or perivascular tissue. [17] It is widely acknowledged that this is a reactive process to chemical, physical, or microbiological stimuli rather than a neoplasm . [ 18 ]

  8. Bladder cancer - Wikipedia

    en.wikipedia.org/wiki/Bladder_cancer

    Bladder cancer is most common in wealthier regions of the world, where exposure to certain carcinogens is highest. It is also common in places where schistosome infection is common, such as North Africa. [56] Bladder cancer is much more common in men than women; around 1.1% of men and 0.27% of women develop bladder cancer. [2]

  9. Esophageal cancer - Wikipedia

    en.wikipedia.org/wiki/Esophageal_cancer

    Most esophageal cancers fall into one of two classes: esophageal squamous-cell carcinomas (ESCC), which are similar to head and neck cancer in their appearance and association with tobacco and alcohol consumption—and esophageal adenocarcinomas (EAC), which are often associated with a history of GERD and Barrett's esophagus. A rule of thumb is ...
