We know that early detection is key. Covid-19 has taken a lot, but it shouldn’t change how health and routine screenings are prioritized.

“If anything good is to come out of what I’ve gone through, I hope it’s that someone else is inspired to take action and take care of themselves, even when it’s difficult,” Julie said.
