Dhaka - growing like a cancer, unchecked and uncontrolled

IS it possible to decentralize the government and move a big part of it outside Dhaka, may be in Joydebpur area or in Tangail? Also, is it possible to limit the population of Dhaka?
Something drastic should be done to check the unruly growth of Dhaka city. Instead of a planned growth, which is healthy, the city is growing like a cancer (unchecked and uncontrolled).
