The annual San Antonio Breast Cancer Symposium kicked off on Tuesday.

Experts in the field come from all over the world to share research breakthroughs and hear what’s next in the fight against the disease.

“I came in the last six years and it’s always exciting to see how much we get improvement,” said Dr. Giampaolo Bianchini, from Milan. “Even every year there is a small improvement. Overall, we have really seen a dramatic change in breast cancer in the last 10 years.”

A scientific finding out of Scotland showed how older women with breast cancer may not need radiation after surgery to survive.

There are a total of four major announcements planned for this year’s symposium, which runs through Saturday.
