@function estimates over 1000x growth in Annul MRI's this decade. The traditional checkup is obsolete.

In the last year we've had to expand from ~30 to ~200 locations to meet demand for @function's 22-minute Annual MRI.

It is now under $1,000 and scans for cancers across brain, pancreatic, prostate, uterine, ovarian, bladder, kidney, spleen, gallbladder, liver, and thyroid. Also scans for aneurysms, strokes, hernias, tears, diverticulitis, iron overload, endometriosis, abnormal cysts, fatty liver. If you add time, it scans the spine and the skeletal system.

Before AI, this took hours and many thousands of dollars. The 22 minute scan time is on track to be reduced much further, and the cost will deflate with it.

AI is the most important technology is medical history.

@PalmerLuckey Widespread MRI usage done at least annually with AI reviewing the data would greatly improve wellbeing and mortality

One chart should change how many think about cancer.

This is U.S. survival data from patients diagnosed between 2011 and 2017.

Local = cancer is only in the organ where it started.

Regional = cancer has reached nearby lymph nodes or tissues.

Distant = cancer has spread to other organs.

Look at what happens to 5-year survival:

Breast cancer
99% (local)
86% (regional)
29% (distant)

Colon cancer
91%
72%
14%

Melanoma
99%
68%
30%

Prostate cancer

99%
99%
31%

Lung cancer
60%
33%
6%

Pancreatic cancer
42%
14%
3%

The numbers are not current. This data is now several years old.

Since then, treatment has improved significantly for melanoma, lung cancer, kidney cancer, and some blood cancers thanks to immunotherapy and targeted therapies.

Progress has been slower for pancreatic cancer, stomach cancer, and metastatic colorectal cancer.

The percentages have changed. The pattern has not.

For many cancers, the biggest difference is not the cancer itself. It’s whether it is found before or after it spreads.

Okay sick. Robinhood just launched a Platinum Card and it's be looking like the single best credit card deal out there

The best perk: Function Health. It's 100+ lab tests covering organ function to cancer markers. The kind of panel insurance won't cover. Normally costs $499/year. Now included.

The card's annual fee is $695.
So after one perk, you're $196 away from breaking even.

Then stack on:
- $250 in DoorDash credits + DashPass
- $200/year for Whoop or other wearables
- Free Amazon One Medical
- Unlimited Priority Pass lounges
- 5% back on flights AND restaurants

It also doesn't force the stupid miles game, every dollar earned goes directly into your brokerage account as cash to invest.
Not even paid to say this i'm just excited to not need to pay $900 for my Amex anymore
