What are the percentages you’ll develop breast most cancers in your lifetime? Not a lady’s common threat—13%, in keeping with the American Cancer Society—however your private threat primarily based in your age, genetics, household historical past, and different threat components?
That’s a statistic you must know off the highest of your head, Dr. Thaïs Aliabadi, an OB/GYN in Beverly Hills, California, and cohost of the brand new podcast SHE MD, tells Fortune.
“I was diagnosed with breast cancer myself, so it’s a condition that’s near and dear to my heart,” she says. “I don’t want another woman to go through what I went through.”
In line with Aliabadi, at 49 she had no genetic mutations, no household historical past of breast most cancers, and her mammograms, ultrasounds, and MRIs have been benign. Nonetheless, she says a breast biopsy seven months earlier had proven precancerous cells. She knew different elements of her medical historical past—akin to having dense breasts and giving birth for the first time after age 30—heightened her threat. She decided her lifetime threat of creating breast most cancers was 37%; the American College of Radiology considers girls with a lifetime threat at or above 20% to be high-risk. Aliabadi requested her physician for a prophylactic double mastectomy, a surgical procedure by which each breasts are eliminated to decrease possibilities of getting breast most cancers.
“Someone with 37% lifetime risk, they need regular imaging every six months and I didn’t want to go through all that; I was too busy,” says Aliabadi, now 53. “I didn’t want to get diagnosed with breast cancer, I just didn’t want to deal with it. To me, that number was high, and it’s a very personal decision.”
Her docs insisted a double mastectomy was pointless. Nonetheless, Aliabadi went by means of with the process. Per week later, she was notified most cancers had been current.
“Do you know how many doctors at my hospital approached me the following month—’cause I’d made a post on Instagram—and asked me, ‘How did you calculate your lifetime risk?’ And these were gynecologists,” Aliabadi tells Fortune. “I realized I got breast cancer so I can change this in the world.”
How do you calculate lifetime breast most cancers threat?
Aliabadi says her dream is for each lady to know her lifetime threat of breast most cancers—data that would probably save her life.
Earlier this month, actress Olivia Munn announced on Instagram that she’d been recognized with luminal B breast cancer in 2023. The 43-year-old had examined adverse for BRCA1 and BRCA2 gene mutations, and her imaging outcomes have been regular. Despite this, Munn’s physician, Aliabadi, assessed her breast most cancers threat, which was additionally 37%. Additional testing revealed most cancers and Munn, too, opted for a double mastectomy.
“I wouldn’t have found my cancer for another year—at my next scheduled mammogram—except that my OB/GYN, Dr. Thaïs Aliabadi, decided to calculate my Breast Cancer Risk Assessment Score,” Munn wrote in a March 13 Instagram post. “The fact that she did saved my life.”
Aliabadi will quickly supply a risk calculator of her own on the SHE MD web site and declined to inform Fortune which algorithm she used on Munn. A number of free variations are accessible on-line, together with the Breast Cancer Risk Assessment Tool (BCRAT), the IBIS/Tyrer-Cuzick Risk Assessment Calculator, the Breast Cancer Surveillance Consortium (BCSC) Advanced Breast Cancer Risk Calculator, and the Black Women’s Health Study Breast Cancer Risk Calculator.
Every has benefits and limitations. The BCRAT, for instance, is easy however primarily based on limited biomedical data for nonwhite women. The IBIS/Tyrer-Cuzick instrument eliminates race however incorporates extra of your reproductive historical past, and the BCSC calculator doesn’t apply to girls underneath 40. Collectively, they analyze components akin to:
- Age
- Age at time of first menstrual interval
- Age at time of first childbirth
- BRCA1 and/or BRCA2 gene mutations
- Breast biopsy historical past
- Breast density
- Breastfeeding historical past
- Household historical past of breast and prostate most cancers
- Peak and weight
- Hormone substitute remedy historical past
- Menopausal standing
- Oral contraceptive use
- Ovarian most cancers historical past
- Race and ethnicity
Relying on the instrument, you’ll be given your short-term threat of creating breast most cancers inside 5 to 10 years and/or your lifetime threat. Plenty of calculators are publicly accessible however meant to be used by medical professionals. Girls shouldn’t solely know their threat, Aliabadi says, but additionally focus on it with their well being care staff.
“This needs to be done at the primary care office, at the gynecologist’s office, at the family practitioner’s office, at the plastic surgeon’s office—offices that basically deal with women directly,” she tells Fortune. “I want this to be standard of care.”
The upcoming SHE MD threat evaluation will embody a printer-friendly motion plan girls can deliver to their subsequent medical appointment “and if their doctor refuses to do something about it, I want them to be empowered to be their own breast advocate and go find a doctor that would do the right thing for them,” Aliabadi says.

What does my lifetime breast most cancers threat imply?
No instrument is ideal, with some underestimating threat amongst sure populations. A girl at low threat could develop breast most cancers, whereas a lady at excessive threat could not. Your physician might help you select which evaluation could provide the finest estimate and decide whether or not further screenings are needed.
Don’t wait till you strategy center age to have these nuanced discussions along with your physician, says Dr. Rebecca Kaltman, an oncologist on the Inova Saville Cancer Screening and Prevention Center in Fairfax, Virginia, who tends to make use of the IBIS/Tyrer-Cuzick instrument for her sufferers.
“We are working [to] educate primary physicians on quick models and tools that they can use to risk assess, so that we’re capturing people early on,” Kaltman tells Fortune. “For those that might be at risk from a hereditary perspective, screening would start a lot earlier. So instead of waiting until 40, when the guidelines say to start screening, we need to be thinking about women at a much younger age, in their 20s and 30s.”
The American Most cancers Society recommends breast imaging for ladies in these age teams:
- 40–44: Annual mammograms elective
- 45–54: Annual mammograms
- 55+: Biannual mammograms, annual elective
Affected person training is important, notably for ladies of colour, Kaltman says, noting that whereas breast most cancers is more common among white women, it happens earlier and extra aggressively amongst Black girls. Early illness detection is a promising answer.
“I think that our obligation as providers is to make sure that we’re getting out into every community and educating women,” Kaltman says. “The more that we can empower patients to know what their risk is and bring this to their primary providers, be it an OB/GYN or an internist, the more likely they are to get risk stratified and appropriate screening going forward.”
