This is a magical, hopeful idea of dolphins as extraordinary, advanced creatures but it’s fantasy.
Can dolphins detect cancer in people? To some scientists, it’s not even a legitimate hypothesis; and to many animal-rights activists, “swim-with-the-dolphin” cancer diagnostic centers would be no less objectionable than any other form of captivity.
The post goes on to give examples of what appear to be cases of extraordinary dolphin “knowledge”
“A woman swimming with Dreamer thought she had been rammed,” Hyson writes. “The woman was taken to hospital for examination. The woman had a large bruise. X-ray revealed that under the ribs, near the center of the bruised area, there was a small tumor. It is my feeling that Dreamer likely ‘zapped’ the tumor with a powerful sound pulse, perhaps to heal it, and the high intensity sound left bruising from hydrostatic shock. At the least, the bruising called medical attention to the tumor.”
Meanwhile, “Dolphins have been known to detect certain types of cancer and pregnancy in some people,” WJHG reports, “But experts say there is no clinical research to back up those behaviors.
As described, there does seem to be a way to test such claims but it still involves a good degree of subjectivity. We have no mechanism for this and we have no testing. We do have a situation where hits are remembered and misses forgotten. And coincidences. Should you believe this is a real thing? No. Not at all.
Many people find magic and mystery in dolphins and project stories and attributes onto them. This is speculation. They can’t see your tumor and “zap” it. But this kind of thinking is common.
But to make things interesting, the article mentions detection of pregnancy as well. This is slightly more plausible (but still dubious) since the fetus is a living thing, moving and giving off signals from the heart beat. This article is a longer version of the one linked above that explains more.
