Your Health: Detecting hard-to-see cancers
LANSING, Mich. (WILX) - In the past 30 years, the death rate from breast cancer has decreased by 43%.
Mammography has long been the standard screening tool, followed by digital mammography, and 3D mammography, but mammograms may not always be the most effective tool for women with dense breast tissue. Now, an affordable abbreviated breast MRI might be the answer to catching cancer in these women earlier than ever before.
Tessa Gauzy’s story is an all too common one.
“I was taking my shower after I felt the lump. I was diagnosed with stage one, B invasive ductal carcinoma,” Gauzy said. “I have no family history.”
But less than 10% of breast cancers are hereditary. That’s why a yearly mammogram is vital to catch cancers before it’s too late.
“Our goal is to detect cancers when they are small, at their earliest, most treatable stage,” said Dr. Brett Parkinson.
But the denser a woman’s breast, the harder it is to detect tumors early.
“Mammography picks up about four cancers per 1,000 women,” Parkinson said. “MRI, on the other hand, can pick up anywhere from 12 to 16 early breast cancers.”
But a full breast MRI is expensive and time-consuming and is currently used now for only the most at-risk patients. Parkinson believes the abbreviated MRI will revolutionize cancer screenings.
“I think that we’re seeing the future unfold right before our eyes,” Parkinson said.
Abbreviated breast MRI uses the same MRI machines, but the difference is, the time inside the MRI is just 10 minutes, it costs less, there are fewer sequences so, less time is spent reading the reports, it’s just as sensitive as full breast MRIs, and it can pick up hard-to-see tumors that mammograms miss.
In dense tissue, mammography sensitivity goes down to less than 50%. Abbreviated MRI allows doctors to see the extent of the cancer and its margins.
The average risk of a woman in the U.S. to develop breast cancer is one in eight.
Parkinson said mammography is still the best and most efficient way to find early-stage tumors and women should get one every single year. Women whose breast cancer is caught at an early stage have a 93% or higher survival rate in the first five years.
