Sofia Vergara is encouraging women to Follow the Script when it comes to their health.

The 40-year-old Colombian actress and Modern Family star has been named the spokeswoman for Follow the Script, a campaign to raise awareness of hypothyroidism.

Vergara, who has spoken out about her own bout with thyroid cancer, was diagnosed with thyroid cancer at 28 and had to have her thyroid removed.

“I was very young, and when they tell you that word (cancer), it’s like, ‘What are you talking about?’ You always think, ‘death.’ You don’t – that’s all you think when they tell you that. So it was – it was pretty scary,” Vergara said on ABC’s Nightline.

She first learned of the problem when she took her son Manolo to his endocrinologist and the doctor noticed an inflammation in her thyroid gland.

The removal of her thyroid left Vergara with hypothyroidism, a condition that requires daily medication.

“In my career, I’m known to ad lib and go off-script-but not when it comes to my health. I make sure to ‘Follow the Script’ so I get exactly what my doctor prescribed,” the actress said.

Roughly one in eight women will suffer from a thyroid condition during the course of their lives, Vergara’s endocrinologist, Dr. Jordan L. Geller, said during the campaign launch at the Trump SoHo in New York.

An estimated 30 million people in the United States suffer from hypothyroidism.
