Kaiser Permanente says it has broken the world record for the most mammograms performed within 24 hours.
Nationally, Kaiser Permanente performed a grand total of 5,939 mammograms in 24 hours.
On Thursday, the staff was going non-stop with more than 240 screenings at five Kaiser clinics in Hawaii.
Doctors say mammograms catch more than 95 percent of breast cancer cases.
Anna Fujimori is a 6-year breast cancer survivor. She says eating right, exercising and great support from her family helped her to get through it. And she knows getting a mammogram ultimately saved her life.
"Sometimes you might say, why go through with all this but it's well worth it and living today, being a 6-year survivor -- very important," said Fujimori.
"Mammograms are clearly not fun, but that simple test that takes a short amount of time can actually save their lives," said Dr. Mabel Wong, Kaiser chief of the OBGYN department.
Doctors say improved technology and higher-skilled staff are now frequently catching cancer well before it can be felt by hand.
