the only way to do it is with medicine. Im studying platyhelminthes at uni at the moment, trust me if it were 30 foot you'd be dead. by the way pulling it does no good. It is segmented and each segment is capable of producing 1000's more tapaeworms. you could pull out a foot of the worm but it will grow back within 6 weeks. If you try to pull it out the tumor it creates in your stomach will lock the head of the worm under it and it will just regrow... good luck
