Definition and causes

Tumors (knots) in the small intestine are rare and most are benign. Malignant (malignant) tumors in the small intestine is less than 1 of all malignant tumors of the gastrointestinal tract. The most common isadenocarcinoma(tumors removed from kirtelvæv - 40%)karcinoid(25%) andmalignantlymphomas(approx. 20%).

The cause is unknown, but chronic inflammation may be involved, and you have an increased risk of malignant tumors by celiac disease (gluten intolerance), Crohn's disease and AIDS.

Adenocarcinoma is the most commonly located in the upper part of the small intestine, while the other most frequently sits in the lower part.

Symptoms of tumors in the small intestine

The symptoms are often the same regardless of whether the tumor is benign or malignant:

  • Pain.

  • Tarmslyng.

  • Bleeding (anemia) by prolonged illness - emerges as fatigue and pallor).

  • Weight loss (by malignant tumors).

  • Perforation (breakthrough of the intestine - seen by lymphomas).

  • Diarrhea (in lymphomas and karcinoid).

  • Red coloration of the face (flushing - seen by karcinoid).

In some cases of lymphoma can chemotherapy (see diagnosis and treatment of cancer) possibly. combined with radiotherapy to be effective.

Select and complications of tumors in the small intestine

Most of adenocarcinoma has spread at the time of diagnosis, and they are often associated with a poor prognosis.

By lymphomas are forecast better, but unfortunately not good. Best if surgery is possible, and worst, if the tumor is associated with celiac disease.

Karcinoider also has a serious prognosis, but this is very dependent on the spread and whether there is proliferation.
