Appendix cancer occurs when cells in the appendix become anomalous and grow without control. These cells form an escalation of tissues called tumor. A lump can be benign (noncancerous) or malignant (cancerous, meaning it can reach to other parts of the body). One more name for this type of cancer is appendiceal cancer.

Types of appendix tumors

There are a variety of tumors that can start in the appendix:

Carcinoid Tumor

A carcinoid cancer starts in the hormone-producing cells that are usually present in petite amounts in approximately every organ in the body. A carcinoid tumor starts mainly in either the GI tract or lungs, but it also may crop up in the pancreas, a man’s testicles, or a woman’s ovaries. An appendix carcinoid lump most often occurs at the tip of the appendix. Roughly 66% of all appendix tumors are carcinoid tumors. This kind of malignancy typically causes no symptoms until it has spread to other organs and often goes unobserved until it is found at some stage in a test or process performed for another reason. An appendix carcinoid cancer that remains restricted to the area where it started has a high possibility of successful cure with surgery.

Mucinous Cystadenocarcinoma

Mucinous cystadenocarcinoma is the most ordinary non-carcinoid appendix cancer and accounts for about 20% of appendix cancer cases. This kind of cancer produces a jelly-like material called mucin that can fill the abdominal nook and can cause abdominal pain, bloating, and changes in bowel function if the growth breaks through the appendix or cultivates in the stomach.

Colonic-type Adenocarcinoma

Colonic-type adenocarcinoma accounts for about 10% of appendix cancers and frequently occurs at the bottom of the appendix. This kind of tumor looks and behaves like the most ordinary kind of colorectal malignancy. It often goes unobserved, and an analysis is regularly made during or after surgical procedure for appendicitis (swelling of the appendix that can result in abdominal pain or inflammation, loss of appetite, sickness, queasiness, constipation or diarrhea, incapability to pass gas, or a low fever that begins after other signs).

Signet-ring Cell Adenocarcinoma

Signet-ring cell adenocarcinoma (so called for the reason that, under the microscope, the cell looks like it has a signet loop inside it) is unusual and well thought-out to be more belligerent and harder to care than other types of adenocarcinomas. This sort of cancer frequently occurs in the abdomen or colon, and it can cause appendicitis when it grows in the appendix.

Paraganglioma

Paraganglioma is an uncommon tumor that develops from cells of the paraganglia, a compilation of cells that come from nerve tissue that persevere in tiny deposits after fetal (pre-birth) maturity, and is found near the adrenal glands and some blood vessels and nerves. This kind of cancer is usually considered gentle and is often fruitfully treated with the comprehensive surgical elimination of the tumor. Paraganglioma is uncommon outside of the head and neck region.
