Comparing economic growth to cancer is extremely incorrect. Cancer grows unchecked causing pain and then death due to a failure of the body's regulatory system. Economic growth happens broadly because your population is growing and you are keeping up production per unit of labor and/or because you develop technology/business improvement that increases production per unit of labor. The latter causes abundance and better life for everyone (even when an outsized portion of the benefit is captured by the creator of the benefit) and the former keeps the standard of living possible for everyone and are very good things. If you want to talk cancer in economic terms that would be market power abuse, not growth. Market power abuse comes in the form of monopoly/oligopoly and the pricing power that situation allows and almost always slows growth (as the monopolist/oligopolist raises prices and decrease production to maximize profits).
In the context of a functioning regulatory system growth is extremely good. Right now governments fail at regulating by regulating both too much (try getting a new drug through the FDA for example) or too little (why hasn't microsoft, google, amazon, facebook, etc. all been broken up by antitrust regulation???). It is correct to lay blame on the regulator and incorrect to lay blame on growth.
