The adenoma, lacking the "carcinoma" attached to the end of it, suggests that it is a benign version of the malignant adenocarcinoma. The gastroenterologist uses a colonoscopy to find and remove these adenomas and polyps to prevent them from continuing to acquire genetic changes that will lead to an invasive adenocarcinoma.
A VIPoma or vipoma (/ v ɪ ˈ p oʊ m ə /) is a rare endocrine tumor [1] that overproduces vasoactive intestinal peptide (thus VIP + -oma). The incidence is about 1 per 10,000,000 per year. VIPomas usually (about 90%) originate from the non-β islet cells of the pancreas. They are sometimes associated with multiple endocrine neoplasia type 1.
Cancers are usually named using -carcinoma, -sarcoma or -blastoma as a suffix, with the Latin or Greek word for the organ or tissue of origin as the root. For example, the most common cancer of the liver parenchyma ("hepato-" = liver), arising from malignant epithelial cells ("carcinoma"), would be called a hepatocarcinoma , while a malignancy ...
The most common, pancreatic adenocarcinoma, accounts for about 90% of cases, [11] and the term "pancreatic cancer" is sometimes used to refer only to that type. [10] These adenocarcinomas start within the part of the pancreas that makes digestive enzymes . [ 10 ]
The signs and symptoms of colorectal cancer depend on the location of the tumor in the bowel, and whether it has spread elsewhere in the body ().The classic warning signs include: worsening constipation, blood in the stool, decrease in stool caliber (thickness), loss of appetite, loss of weight, and nausea or vomiting in someone over 50 years old.

Signet ring cell carcinoma (SRCC) is a rare form of highly malignant adenocarcinoma [1] that produces mucin. It is an epithelial malignancy characterized by the histologic appearance of signet ring cells .
Adenocarcinoma is more common in patients with a history of cigarette smoking, and is the most common form of lung cancer in younger women and Asian populations. The pathophysiology of adenocarcinoma is complicated, but generally follows a histologic progression from cells found in healthy lungs to distinctly dysmorphic, or irregular cells ...
Some people, such as those with nevoid basal cell carcinoma syndrome or retinoblastoma, are more susceptible than average to developing cancer from radiation exposure. [74] Children and adolescents are twice as likely to develop radiation-induced leukemia as adults; radiation exposure before birth has ten times the effect.
