One hospital's push to bring genetic cancer testing to more Black women

- Tashauna Reid

Breast cancer tends to hit Black women at younger ages and be more aggres‐ sive, but they're underrep‐ resented when it comes to genetic screening, say doc‐ tors launching a new awareness campaign.

The awareness campaign, announced Wednesday by Women's College Hospital in Toronto, focuses on genetic screening for changes or mu‐ tations in two key genes, BR‐ CA1 and BRCA2, as well as others.

Dr. Aisha Lofters, a family physician and researcher at the hospital, helped start the Take Action, Take Control ini‐ tiative that is designed to em‐ power Black women to learn more about genetic cancer testing.

Screening aims to catch a disease like breast cancer be‐ fore it causes any problems that the patient notices, Lofters said.

WATCH | Program offers genetic cancer testing to Black women:

"The idea of that is that by catching it very early, you're able to change the path of that disease, so you're actual‐ ly able to literally save lives," she said in an interview.

When the BRCA1 or BR‐ CA2 genes aren't working properly due to mutations, they are strongly associated with breast, ovarian and prostate cancers. According to Women's College Hospital, it's estimated one in every 300 to 400 Canadians carries a BRCA1/2 gene mutation, which is about the same in the U.K. and more common in the U.S.

The hospital and Canadi‐ an Cancer Society estimate BRCA mutations predispose people to a higher lifetime risk of cancers compared with the average lifetime risk in the general population:

Breast cancer - 70 per cent vs. 13 per cent. Ovarian cancer - 20 to 40 per cent vs. 1.4 per cent. Prostate cancer - 35 per cent vs. 12.3 per cent.

Researcher­s at Women's College Hospital say Black people are vastly underrep‐ resented in its Screen Project program, making up 1.5 per cent of participan­ts since it launched in 2017. Black indi‐ viduals make up 9.6 per cent of Toronto's overall popula‐ tion.

"We see these genes oc‐ curring in all ethnic and racial communitie­s, but what we do realize is that the knowl‐ edge about these genes is lower than it should be in the Black community," said Lofters.

The screening is done through blood tests, cheek swabs or saliva samples. The Screen Project is promoting saliva based self-test kits for a fee and results take up to eight weeks.

BRCA status leads woman to opt for mastec‐ tomy

Provincial programs cover the testing and genetic coun‐ selling depending on imme‐ diate family history or if an individual has cancer. Other people with a less direct con‐ nection to cancer can choose to pay several hundreds of dollars out of pocket for di‐ rect-to-consumer testing, which provide results alone and may not include genetic counsellin­g.

Elysia Bryan of Toronto was offered free genetic provincial screening after she noticed a lump growing on her right breast in 2021 when she was 34.

"My first thought was 'I'm going to die,' " Bryan re‐ called. "My mind went to the darkest possible option, and I know now that the doctor was telling me at the time it was treatable."

Bryan, who had a lumpec‐ tomy and eight rounds of chemothera­py, has a family history of breast cancer, which she wasn't aware of at the time of her diagnosis. She says that's what "opened up that conversati­on," with her family.

After she learned she has the BRCA2 mutation, Bryan decided to have a double mastectomy with reconstruc‐ tion as well as a month of ra‐ diation to prevent a recur‐ rence of cancer.

Bryan says it was impor‐ tant for her to have the testing and to know the infor‐ mation it provided so she could make plans for her family and career. She also shared her diagnosis with rel‐ atives so they know they could also be at risk.

Encouragin­g accessibil‐ ity and awareness

Other options for people with BRCA1 or 2 mutations include taking medication­s, depending on the type of cancer, and more breast ex‐ ams.

Bryan had provincial­ly funded genetic screening at another hospital, but she wanted to share her story as part of the campaign at Women's College.

"When I was searching for informatio­n, there wasn't a lot of stories of people who looked like me or who were in my age range," she said.

Dr. Onye Nnorom, an as‐ sistant professor at the Dalla Lana School of Public Health and a family doctor, is not in‐ volved in the Women's Col‐ lege project, but her work fo‐ cuses on anti-Black racism as a driver of inequities in Cana‐ da.

Among "Black women, particular­ly women of West African descent and Central African descent … there is a risk of more aggressive breast cancer that presents at younger ages," Nnorom said, noting it tends to be harder to treat.

Knowing genetic screen‐ ing is available is key, Nnorom said. "What we're hearing in community is that a lot of women do not know about this."

Lofters suggests people talk to their family openly about cancer and if there is a history of it.

"I think for many people and many communitie­s, we don't talk sometimes about why aunty so and so died and why grandma died," she said. "It is so important to know what you might be at high risk for."

Lofters and Nnorom also want physicians to have con‐ versations with their patien‐ ts.

"We really need to make sure that our health-care providers are aware of this is‐ sue that we're seeing interna‐ tionally with Black women having poorer outcomes when it comes to survival," Nnorom said.
