  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 ...

    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]

    [11] [12] [13] Alternatively, they may point to non-cancerous disease processes, benign tumors, or even be within the physiological range of normal. They may appear at the primary site of cancer or be symptoms of cancer metastasis, or spread. Further workup by a trained healthcare professional is required to diagnose cancer.

  6. Dysplasia - Wikipedia

    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 ...

    Symptomatic features of paraneoplastic syndrome cultivate in four ways: endocrine, neurological, mucocutaneous, and hematological.The most common presentation is a fever (release of endogenous pyrogens often related to lymphokines or tissue pyrogens), but the overall picture will often include several clinical cases observed which may specifically simulate more common benign conditions.

    Hypopharyngeal cancer is a disease in which malignant cells grow in the hypopharynx (also known as the laryngopharynx) the area where the larynx and esophagus meet. [ 1 ] It first forms in the outer layer ( epithelium ) of the hypopharynx (last part of the pharynx), which is split into three areas.
