After my father died final 12 months of pancreatic cancer at 72, I discovered myself desirous about a query that is simple to keep away from whenever you’re wholesome: How a lot of my future is already written into my biology?
To search out out, I enrolled in an government well being program at Human Longevity, a Silicon Valley clinic that mixes full-body imaging, blood testing, and genomic sequencing to evaluate well being dangers and longevity. In whole, the checks value about $12,000.
What I discovered was each reassuring and unsettling.

Over the course of about 4 hours, I underwent a battery of checks, together with a whole-body MRI, intensive blood work, and genetic sequencing. The upside is that a number of the outcomes supplied the information I hoped for.
My MRI scans had been clear, my arteries confirmed no calcification, and better of all, a blood take a look at designed to detect alerts from greater than 50 cancers got here again adverse.
On the similar time, nevertheless, the testing uncovered dangers I hadn’t anticipated.
The most cancers outcomes mattered most

Most cancers was the factor I cared about most going into the method. Throughout my follow-up session, I requested Dr. Keon Pearson, a clinician at Human Longevity, about my threat for pancreatic most cancers, particularly.
He pointed to 2 encouraging findings: a traditional CA19-9 (Most cancers Antigen 19-9) biomarker outcome and a adverse GRAIL Galleri liquid biopsy take a look at, which is especially delicate for pancreatic, liver, head and neck, and esophageal cancers, Dr. Pearson stated.

The excellent news was that he instructed me my take a look at outcomes indicated I had a 99% probability of being cancer-free.
After I later met with a genetic counselor to overview my genome sequencing outcomes, I discovered that the clinic hadn’t recognized any of the high-risk inherited mutations it screens for throughout greater than 2,000 circumstances. That included hereditary cancer syndromes.
For somebody whose father died of pancreatic most cancers, that was a aid.
The numbers that shocked me

A few of my outcomes had been much less easy, nevertheless.
At 6-foot-4 and 246 kilos, my physique mass index measured 30.1 kg/m², which technically locations me within the overweight class. Pearson rapidly identified that BMI doesn’t tell the whole story.
My body-fat proportion got here in at 23.6%, barely above the clinic’s most well-liked vary for males. On the similar time, my skeletal muscle index was so excessive that Pearson instructed me it was “one of many highest I’ve seen.”
My bone density was additionally robust, rating at the least within the 84th percentile. My coronary artery calcium rating was zero, that means no calcifications had been detected in my arteries that would in any other case elevate my risk of heart disease.
Nonetheless, there have been areas the place Pearson stated I might enhance.
My liver-fat measurement of three.1% fell throughout the regular vary, however he stated it was above what he would think about optimum for longevity.
Then there was the one marker I could not merely repair with diet or exercise.

Pearson instructed me I had elevated lipoprotein(a), or Lp(a), a cholesterol-related particle that’s genetically decided. Elevated Lp(a) is related to stiffer coronary heart valves and a raised threat for coronary heart assault and stroke.
“It is most likely six occasions extra harmful pound for pound in comparison with LDL cholesterol,” Dr. Pearson stated.
“It isn’t delicate to your eating regimen. It isn’t delicate to train,” he stated. Basically, this quantity will not budge with out prescribed drugs.
The DNA outcomes I wasn’t anticipating
What I did not anticipate was my genetic take a look at outcomes.
I discovered that I am a service for a number of recessive genetic problems, together with phenylalanine hydroxylase deficiency, higher referred to as PKU.
PKU is a genetic dysfunction that forestalls the physique from breaking down the amino acid phenylalanine and, if not handled, can construct up and trigger extreme mind harm. It is the explanation why meals and drinks with aspartame, a synthetic sweetener that accommodates phenylalanine, have a warning label.
As a result of I carry just one copy of the gene variant, I haven’t got the illness, and my spouse would not carry it, so our youngsters weren’t at risk.
Then we obtained to the neurological dangers.
My genetic counselor defined that I carry one APOE3 gene and one APOE4 gene. In response to Human Longevity’s evaluation, that raises my lifetime threat of Alzheimer’s illness above the overall inhabitants. However all of my grandparents made it to the tip of their lives with out dementia.
“I’ll simply say that my preliminary response to that is considerably alarmed,” I instructed the genetic counselor throughout the session.
The report additionally positioned me within the 99th percentile genetically for Parkinson’s disease threat. The counselor emphasised that absolutely the lifetime threat remained comparatively low — about 2.7%.
Then, in spite of everything of that, I obtained one closing piece of fine information.
I carry a variation of the FOXO3 gene, which researchers affiliate with a larger probability of residing previous age 90.
That discovering instantly made me consider my maternal grandfather, who lived to 98.
The expertise did not inform me how lengthy I will reside. No take a look at can do this.
What it did reveal was one thing extra sensible: which dangers seem hardwired into my DNA, and which of them nonetheless reply to the alternatives I make day-after-day.
Among the playing cards are already on the desk. What I do with the hand continues to be as much as me.
