  • There is no established cause for small intestinal cancer.
  • However, some genetic syndromes are associated with small intestine cancers.
  • Intestinal cancer caused by the genetic syndrome in the presence of a family history, are diagnosed at a younger age.
  • Single nucleotide mutations, either on the same chromosome or on different chromosomes are considered to be associated with such cancer-associated genetic syndromes.
  • Small intestinal cancers may also be sporadic.[1]
  • According to some studies done in Europe and United States, tobacco, alcohol, and obesity are considered to play a role in the etiology of small intestine cancers.[2]
