Sharing Mayo Clinic: Stubborn Cancer and Proton Beam Therapy
Audra Popp has a rare tumor – anaplastic pleomorphic xanthoastrocytoma, also known as anaplastic PXA. Only a handful of people are diagnosed with this condition each year. Audra is the first person at Mayo Clinic with anaplastic PXA to be treated with proton beam therapy.
Audra had 20 proton beam therapy sessions to try to destroy fast-growing cells possibly left behind after surgery.
But proton beam therapy is just the latest step in the battle against Audra's tumor. She's had five craniotomies since 2001, and she has a scar from her right ear to the crown of her head as evidence. She had surgeries at Mayo in 2007, 2009, 2014 and 2015. She also has had three regimens of chemotherapy through the years and six weeks of radiation therapy at Mayo Clinic in 2007.
The tumor has become more aggressive. And each time her surgeons think they have it completely removed, it comes back. Read the rest of Audra's story.
