The main ingredient of 714-X is camphor, which comes from the wood and bark of the camphor tree (see Question 1).
It is claimed that 714-X helps the immune system fight cancer (see Question 3).
No study of 714-X has been published in a peer-reviewed scientific journal to show it is safe or effective in treating cancer (see Question 6).
714-X is not approved by the US Food and Drug Administration for use in the United States (see Question 8).
External Validity: Poor. Studies on populations in high-risk areas may not be applicable to low-risk areas such as the United States.
Based on solid evidence, screening would result in uncommon but serious side effects associated with endoscopy, which may include perforation, cardiopulmonary events, aspiration pneumonia, and bleeding requiring hospitalization.
False-positive tests are also common in association with serum pepsinogen or gastric photofluorography.
Magnitude of Effect: Good evidence for rare but serious harms.
Description of the Evidence
Study Design: Evidence obtained from screening programs and from case series.
Internal Validity: Fair.
Consistency: Inadequate evidence.
External Validity: Poor.
