A California teen who was diagnosed with a rare lung cancer two months ago has died.

The 16-year-old Azusa High School cheerleader died on March 6, just a few days before a benefit was to be held to help raise money to assist with her medical costs. Her family chose to remove her from life support since her condition wasn’t improving, reports KABC. They posted the following message on a Facebook page dedicated to the Martinez:

"It's with a heavy heart that I regret to inform everyone that Sandra passed away at 12:05 this afternoon. She was surrounded by family and went peacefully. Our family would like to thank everyone for their prayers and support as well as ask for privacy during this time. Thank you again."

Sandra was diagnosed with lung cancer in January. After cheering at a basketball game, Martinez told her mother she was having trouble breathing. Her mother took her to the emergency room, where doctors discovered a 7-inch cancerous tumor on her lungs. Doctors attempted to get a biopsy of the tumor during a risky procedure, but one of her lungs collapsed. She then placed in a medically-induced coma.

Many people from around the country continue to share their condolences with Martinez’s family on the teen’s Facebook page.
