This doctor detected a cancerous tumor in his neck using a pocket-sized ultrasound device connected to his iPhone. <br /><br />Dr. John Martin was testing the "Butterfly IQ" device after joining its creators' company as chief medical officer. After he had felt a thickness in his throat, he scanned the area with the device. He detected a three-inch mass, and a biopsy later confirmed it was cancerous. <br /><br />The device, developed by Connecticut-based start-up Butterfly Network, pairs with the user’s iPhone and is significantly cheaper than regular ultrasound machines, costing about 10 times less than the lowest-end system. That means easier access for users, and quicker diagnoses, which could save lives.
