Fuck cancer.
Take back some control.
I'm Russ. I've had stage 4 bowel cancer since 2021. FC:AI is where I share everything: my data, the AI tools I use, and what's actually helped. It's for patients and carers who want a bit more control, and for anyone who might know something I don't.
Right now: Cycle 4 of FOLFIRI + cetuximab rechallenge · profile updated 30 September 2026
What's changed in the last two weeks
Cycles 3 and 4 · 16 Sep – 1 Oct. I rebuild this every two weeks, in time with my chemo cycle — bloods, tracking, the cycle map and anything new that's come out of sharing all this. If you've been here before, this is the bit that's new.
- CEA is 44.6, down from 50.9 on 14 September and 146.0 on 1 September. Third fall in a row — about 69% across three cycles of the restart.
- Cycle 3 was physically easier than Cycle 2. Same drugs, same doses; what changed was soup-only through the nadir weekend and stepping the laxatives down once things moved. No GI emergency this time.
- Haemoglobin (126) and red cells (4.09) have drifted just under range. ALP is still high at 169. Bilirubin 21, marginally over — I have Gilbert's syndrome.
- Cycle 4 started on 30 September. Cycle 5 is 14 October, with a CT scan after it.
- I finally pinned down what sequencing I've actually had: a 517-gene panel, aligned to hg19. Not whole genome. Not whole exome. A lot of people assumed otherwise, including me.
- The tumour panel is reported tumour-only, so my inherited variants are sitting inside it — that matters for anyone reanalysing it.
- Daily tracking now runs to 29 September: 40 days, morning and evening, across three cycles.
- The cycle map is now Cycle 4, with metformin established from day 4.
- The full manifest of my raw sequencing package — 17 files, 36GB, every size and MD5 checksum. The files themselves are available on request.
- Daily tracking as a CSV, 20 August to 29 September.
- The 29 September bloods as a PDF, identifiers redacted.
- The Cycle 4 map as a PDF.
- The card as PDF, plain text and JSON.
- A genomics researcher read this site and pointed out that panel testing isn't whole genome sequencing — and that sequencing tumour and normal tissue together is what opens a personalised therapy route. Three people have now said the same thing independently.
- There's an NHS route to it. The South West Genomic Medicine Service covers Bath. That's the next call I make.
- An oncologist has offered to work on vaccine design voluntarily, and flagged that sequencing deep enough for that is a different, deeper job than clinical sequencing.
- Five vials of blood went to a blood analysis company at the end of September.
- One gap I can't close yet: the platelet figure on my copy of the 29 September report is unreadable, so it's blank rather than guessed.
My whole cancer, on one card
Diagnosis, genetics, chemo and doses, latest bloods, scans, what I'm taking and what I'm looking for. One page, always the latest version, free to download.
Behind it sits the full record: every blood test since April 2025, every scan, the genomics and a daily chemo log. It's all public, because the more people who can see it, the more chance someone spots something.
Three things worth reading
Why I'm open sourcing myself
You already have a huge amount of information about yourself. Pulled together, it's useful to every doctor, nurse and second opinion you ever see. And the more people who see mine, the better my odds.
Read why → So farWhat it's done for me
A genetic specialist in Australia. The vaccine team at Serova. A specialist in Argentina. A genomics researcher who spotted what my testing was missing. None of that happens if the data stays in a drawer.

Why I've changed FC:AI, and what it is now
Less "here's how to build a tool". More "here's everything, go and do something useful with it".
I'm Russ
I was diagnosed with stage 4 colorectal cancer in 2021. It's incurable but treatable, and I'm still being treated. I spent almost 20 years in PR and communications, and I'm based in Bath.
I use AI every day to manage treatment: tracking chemo, keeping my records in one place, and asking better questions. FC:AI is where I share it, with no pink ribbons and no bullshit. I've spoken about it on the main stage at HIMSS Europe, in Health Awareness (distributed with the Guardian), in Business Insider and on a couple of podcasts.
I also run Known & Cited, an AI brand intelligence company. Different project, same person.
