Be careful not to conflate chemical and mechanical properties. They share chemical properties, but do not share the mechanical property that makes Asbestos carcinogenic. Asbestos breaks down into particles of a dangerous size and shape. Glass and rock wool fibres are shaped differently and do not break in the same way. Glass/rock wool has been used extensively in practice and no link with cancer has been found to date.
