Stomach Cancer May Start in Bone MarrowTopics: Stomach cancer
Findings, published in the Nov. 26 issue of Science, are in stark contrast to the commonly held belief that cancers originate from the tissue in the surrounding area, such as in stomach cancer, in which it has been believed that stomach cancer begins from stomach stem cells. The new study in mice found that stomach cancer cells began as bone marrow cells that had migrated to the stomach which traveled to the stomach in response to inflammation caused by an infection with Helicobacter pylori, the bacterium that causes ulcers. Read more on the here.
This research could eventually lead to new treatments and new ways of diagnosing stomach cancer, a disease without significantly effective treatments at the present.
As is mentioned in the article, it's important for people to realize that not everyone with H. pylori, a relatively common infection, will go on to develop stomach cancer, and we should keep in mind that some scientists doubt the theory and suggest the cells could just be fusing with existing cells in the stomach.
