Genetic testing: do we really want to know the results?

On the 20th, the Financial Times published an article entitled "Genetic Testing: Do We Really Want to Know the Results?" written by the senior American business reporter for David Crowe.

The article says that many of my maternal relatives have cancer

This is one of the calls I will never forget

Soon after Uncle John’s diagnosis, his two younger brothers also underwent prostate cancer tests and found that they also had the disease
.
Uncle Allen lived for another 10 years, but at the beginning of last year, he died after a short period of fighting esophageal cancer, just a few weeks after his 59th birthday

Everyone in our family firmly believes that they will be tortured by this genetic curse
.
After we learned that there is a clear genetic link between prostate cancer and ovarian cancer, this belief became more deeply ingrained-my mother died of ovarian cancer in 1984, when I was only 9 months old and she was only 35 years old

When Uncle John died, I never thought that I might die of cancer myself; like most people in their 20s, death was very far away from me
.
But as time passed, I began to think about whether I might have inherited the disease-causing genes

Genetic testing is a lucrative industry
.
Last year, the industry’s oldest and most prestigious giant genetic company generated $632 million in revenue for genetic testing, including a "my risk" test that analyzes 28 genes (related gene defects may increase the risk of cancer)

One in five women with ovarian cancer has a mutation in this type of gene
.
In 2013, actress Angelina Jolie underwent preventive double mastectomy after undergoing massive genetic testing

For those who want to undergo genetic testing, the first step is to seek the help of a genetic counselor
.
A genetic counselor is a scientist who finds out the risk of disease by combing through an individual's family genetic history

In the end she drew a detailed family map

Males are replaced by squares and females are replaced by circles
.
Those who were diagnosed with cancer were shaded, while those who died of cancer were crossed out with a diagonal line
.
The situation of the Hayes family on my mother's side is worrying
.
Of the 7 nuclear family members-parents and 5 children-5 people were diagnosed with some kind of cancer, and only 1 of them survived
.

My aunt Alma is the only one of the five children in the Hayes family who has never been diagnosed with cancer
.
Her mother and my grandmother also died of cancer
.
She can feel the pain of loss without looking at the map
.
"Looking at all the photos, I found that I was almost the only one still alive," she said
.
"This is terrible.
You will ask yourself why God didn't destroy other families like ours
