A chromosome abnormality called aneuploidy can cause cancer, U.S. researchers said in a study published Monday, confirming what scientists have long suspected. 

With virtually all human cancers having an abnormal number of chromosomes, scientists have “long suspected that gene mutations which promote erroneous chromosome separation during cell division are to blame for tumor development,” researchers at the Mayo Clinic said in a statement…

“The cell loses the ability to suppress tumors, which is part of the immune system,” said Mayo Clinic spokesman Bob Nellis.
