Ill with cancer, even the most ancient invertebrates

Cancer least the first multicellular organisms. This discovery led Professor Thomas Bosch, from Kiel University at the conclusion that humanity will never be able to eliminate it.





BOSH with his colleagues not only discovered the cancer cells have the most primitive animals, but have recorded real cases of malignant tumors Hydra. The Professor has spent many years of his life to the study of the functioning of stem cells and tissue growth of these freshwater invertebrates (are relatives of jellyfish and corals). According to reports, these appeared in the Precambrian, around 550 million years ago. Cancer detection such primitive creatures became the first act in history.





Cancers Hydra recorded at the cellular level. Cancer develops only in females hydras and resembles a carcinoma of the ovaries in women. Thus, the invasiveness of cancer cells developed at the dawn of evolution. The insights of Thomas Bosch largely support the theory of the American physicist Paul Davies, who suggested the existence of cancer even in the earliest multicellular organisms. Cancer successfully passed through billions of years of evolution and has reached our days. Also Paul Davies has concluded the option of activating cancer in the body due to stress factors.
