Hello Everyone,
On Monday August 6, 2018, I underwent an elective bilateral salpingo-oophorectomy (surgery to remove both ovaries and Fallopian tubes). This was done because I have the BRCA2 gene mutation. This was a totally accidental and shocking finding when I did a 23andMe saliva test, just because I was curious. 23andMe is a direct-to-consumer genetic testing service which evaluates your DNA via saliva then sends a report with information about your ancestry and genetic predisposition to some diseases.
BRCA1 & BRCA2 Genes
The surgery went well, and I am doing fine. My reason for sharing this is because some women and men carry the BRCA1 or BRCA2 gene yet have no idea that they possess a variant. Human DNA is about 99.5% identical from person to person. However, there are small differences that make each person unique. These differences are called variants. It is crucial to know if you possess a variant in the BRCA1 and BRCA2 genes because variants in these genes are associated with an increased risk of developing certain cancers, including breast cancer (in women and men) and ovarian cancer. Also, there is a risk of transmitting the gene to your children.

About 1 in 400 people in the general population has a BRCA1 or BRCA2 variant linked to hereditary breast and ovarian cancer. Among people of Ashkenazi Jewish descent, about 1 in 40 has a variant.
The risk estimates shown in the table below represent the proportion of people expected to develop a given cancer during their lifetime. Estimates for the general population are based on observed cancers among people in the United States.

BRCA1 & BRCA2 Variant Gene mutation
Women with a BRCA1 variant have a 45-85% chance of developing breast cancer by age 70 and a 39-46% chance of developing ovarian cancer. They may also have an increased risk for pancreatic cancer.
Women with a BRCA2 variant have a 45-85% chance of developing breast cancer by age 70 and a 10-27% chance of developing ovarian cancer. They may also have an increased risk for pancreatic cancer and melanoma.
Men with a BRCA1 or BRCA2 variant have an increased risk for male breast cancer and may have an increased risk for prostate cancer, pancreatic cancer, and melanoma.
Doing this test quite possibly saved my life. Because of what I now know, I’m undergoing surveillance of my breasts every 6 months and investigating protocols for pancreatic cancer screening. At least I can be proactive which is what anti-aging medicine is all about.
