German porn star Caroline Berg hoped to upgrade her bust size from 34F to 34G. On January 11, she underwent her sixth breast enlargement surgery in Hamburg, but fell into a coma due to severe postoperative complications shortly after the operation. Her heart stopped twice, and she could only rely on an artificial cardiopulmonary machine to maintain her breathing and circulatory system. After struggling against death for 9 days, she was declared dead at 14:30 on January 21. According to industry insiders, Berg's cause of death might be due to the doctor injecting her with an overdose of estrogen. These sex hormones used to stimulate breast growth triggered the complications, leading to her heart stopping while under anesthesia.
