[3] [4] Cancer can be difficult to diagnose because its signs and symptoms are often nonspecific, meaning they may be general phenomena that do not point directly to a specific disease process. [5] In medicine, a sign is an objective piece of data that can be measured or observed, as in a high body temperature (fever), a rash, or a bruise. [6]
Stomach cancer, also known as gastric cancer, is a malignant tumor of the stomach. It's a cancer that develops from the lining of the stomach . [ 10 ] Most cases of stomach cancers are gastric carcinomas , which can be divided into a number of subtypes, including gastric adenocarcinomas . [ 2 ]
The objective of cancer screening is to detect cancer before symptoms appear, involving various methods such as blood tests, urine tests, DNA tests, and medical imaging. [1] [2] The purpose of screening is early cancer detection, to make the cancer easier to treat and extending life expectancy. [3]
Gastrointestinal cancer refers to malignant conditions of the gastrointestinal tract (GI tract) and accessory organs of digestion, including the esophagus, stomach, biliary system, pancreas, small intestine, large intestine, rectum and anus. The symptoms relate to the organ affected and can include obstruction (leading to difficulty swallowing ...
To confirm the diagnosis of gastrinoma a series of blood tests must be made. One of those tests is the serum gastrin level, which is the most reliable test for patients with gastrinoma. The normal levels of gastrin are 150 pg/mL ( > 72.15 pmol/L); therefore elevated levels of > 1000 pg/mL (> 480 pmol/L) would establish the diagnosis of ...
The stomach is an organ of the gastrointestinal tract that sits in the abdomen. [1] Tumors of the stomach are known as gastric tumors, and can be either benign or malignant (gastric cancer). These tumors arise from the cells of the gastric mucosa which lines the stomach. Typically, most gastric tumors are cancerous and not detected until a ...
Barium X-ray examinations are useful tools for the study of appearance and function of the parts of the gastrointestinal tract. They are used to diagnose and monitor esophageal reflux, dysphagia, hiatus hernia, strictures, diverticula, pyloric stenosis, gastritis, enteritis, volvulus, varices, ulcers, tumors, and gastrointestinal dysmotility, as well as to detect foreign bodies.
Ultrasound can ablate tumors or other tissue non-invasively. [4] This is accomplished using a technique known as high intensity focused ultrasound (HIFU), also called focused ultrasound surgery. This procedure uses generally lower frequencies than medical diagnostic ultrasound (250–2000 kHz), but significantly higher time-averaged intensities.
