Stomach cancer, also known as gastric cancer, is 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] Lymphomas and mesenchymal tumors may also develop in the stomach. [2]
Constitutional Symptoms. Unexplained weight loss: Weight loss that is unintended and not explained by diet, exercise or other illness may be a warning sign of many types of cancer. Unexplained pain: Pain that persists, has no clear cause, and does not respond to treatment may be a warning sign of many types of cancers.
Cancer of the stomach, also called gastric cancer, is the fourth-most-common type of cancer and the second-highest cause of cancer death globally. [2] Eastern Asia (China, Japan, Korea, Mongolia) is a high-risk area for gastric cancer, and North America, Australia, New Zealand and western and northern Africa are areas with low risk. [5]
Cancer-related fatigue is a symptom of fatigue that is experienced by nearly all cancer patients. [1] Among patients receiving cancer treatment other than surgery, it is essentially universal. Fatigue is a normal and expected side effect of most forms of chemotherapy, radiation therapy, and biotherapy. [2] On average, cancer-related fatigue is ...
Carcinoid syndrome is a paraneoplastic syndrome comprising the signs and symptoms that occur secondary to neuroendocrine tumors (formerly known as carcinoid tumors). [1] The syndrome is caused by neuroendocrine tumors most often found in the gut releasing biologically active substances into the blood causing symptoms such as flushing and diarrhea, and less frequently, heart failure, vomiting ...
Gastric lymphoma. Endoscopic image of gastric MALT lymphoma taken in body of stomach in patient who presented with upper GI hemorrhage. Appearance is similar to gastric ulcer with adherent blood clot. Primary gastric lymphoma (lymphoma that originates in the stomach itself) [1] is an uncommon condition, accounting for less than 15% of gastric ...
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).
Cancer is caused by genetic changes leading to uncontrolled cell growth and tumor formation. The basic cause of sporadic (non-familial) cancers is DNA damage and genomic instability. [1][2] A minority of cancers are due to inherited genetic mutations. [3] Most cancers are related to environmental, lifestyle, or behavioral exposures. [4]
