(NEW YORK) — Mammograms are not something most women look forward to, but just like the 37 million other women who get a routine mammogram each year, Judy Valencia of Saginaw, Mich., has been vigilant about her check-ups.
“My sister had breast cancer, my mother had breast cancer and my three aunts also had breast cancer,” Valencia told ABC’s Nightline anchor Cynthia McFadden.
But when doctors saw an abnormality on one of her mammograms, they decided to biopsy Valencia’s breast tissue. Based on the results of that biopsy, she was told she had cancer.
“There is no one who questions a biopsy and gets it double checked,” Valencia said.
According to the American Cancer Society, more than 230,000 new cases of invasive breast cancer in women are diagnosed each year and breast cancer is the second leading cause of death in women, after lung cancer. But Dr. Elisa Port, one of the nation’s leading breast surgeons who works at Mount Sinai’s Dubin Breast Center, said women must absolutely get a second opinion if they have been diagnosed.
“We see patients all the time, they come in with their reports all the time and their diagnosis says breast cancer,” Port said. “We pass the slides off to our pathologists, who sends me back a report a day later saying, ‘don’t agree, this is not cancer,’ and it’s very clear cut that it is not.”
“That’s probably one of the most critical pieces of information,” she added. “That’s why no one gets near an operating room until those slides are reviewed.”
In 2006, Susan G. Komen for the Cure, the prominent breast cancer survivors’ organization in the U.S., released a study that estimated that as much as 4 percent of breast cancer diagnoses were incorrect, meaning more than 90,000 people currently living with breast cancer may have been misdiagnosed.
Dr. Ira Bleiweiss, one of the country’s leading breast pathologists, said diagnosing breast cancer these days can be more difficult because mammograms have become so much better, now able to detect smaller and smaller lesions.
While some diagnoses are straightforward, not all cancers are the same. Bleiweiss said it is a “very common occurrence” for him to be presented a slide where the tissue can seem ambiguous.
“These are things that are subject to interpretation and more expertise in making that interpretation is better,” Port added.
