Complete, consent-logged case files for cancer patients seeking a second opinion
TL;DR Folioway assembles the full case file a cancer patient needs before a second opinion at a big cancer hospital: reports, scans, discharge notes and the biopsy slides themselves. Tertiary hospitals pay per complete file because incomplete files waste specialist time. Families can also pay directly.
A second opinion is only as good as the file that reaches the reviewer. At a regional cancer institute in eastern India, pathologists re-reviewed 2,551 outside tissue diagnoses in one year and found significant discrepancies in 171 of them (6.7%). They advised a fresh biopsy in 69 cases, and 24 were hard to read purely because the original slides were badly processed[1].
A 2026 review of 60 studies found that when patients sought a second opinion themselves, up to 69% saw a change in diagnosis, treatment plan or prognosis, though results varied widely between studies[2]. Yet families still turn up with paper folders, a scan CD that won't open and no slides, because nobody asked the first lab to release them.
What it does, in regulatory terms - records collection and logistics only. Folioway gives no medical opinion and makes no diagnosis. The reviewing doctor does that, under the rules that already govern them.
After the patient signs up, often at the referral desk of the receiving hospital, a coordinator pulls records through ABDM where the first provider is linked, and chases the rest by phone, email and courier. That includes the paraffin blocks and slides, which travel by tracked courier to the reviewing pathology lab. The hospital receives one indexed file with a checklist showing what is complete and what is missing, plus a log of every consent the patient gave.
The seed proposed a blockchain exchange for health data. I've dropped the blockchain, and I don't miss it one bit. ABDM's consent manager already records who shared what and when, and over 90 crore ABHA accounts exist[3]. The real gap is the unlinked records and the physical slides.
The patient and family use it. The first payer to target is the tertiary cancer hospital's second-opinion or international desk, which gains a complete file before the first consult. There's no public price list for Indian hospital second-opinion services, so a per-file fee in the low thousands of rupees is an assumption you'll need to test. Families travelling from another state are a second payer, buying the service directly before they book.
ABHA crossed 90 crore accounts in May 2026[3], so more first providers can push records through consented links instead of paper. The DPDP Act 2023 now sets clear consent, withdrawal and breach-notification duties[4], which favours a service that keeps a clean consent trail over chat-app forwards between strangers.
There is no public figure for how many cancer second opinions happen in India, or what families spend on gathering records. The firmest signal is clinical - a 6.7% significant-discrepancy rate across 2,551 re-reviewed cases at one institute[1]. Treat volumes as unknown until you count referrals at two or three hospitals yourself.
Big Indian hospitals run second-opinion desks, but I couldn't find a public page that explains how they collect records or slides. Included Health in the US is the clearest model: its care team gathers records, labs and imaging, then a specialist writes an opinion in 7–14 business days[5]. Folioway does only the gathering, which lets it serve any reviewing hospital instead of competing with them.

| Time to launch | 6–9 months |
The software is modest. The difficulty is in chasing small labs and nursing homes that don't answer, getting blocks released and courier handling that keeps tissue safe. A hospital also has to trust that your checklist is accurate before it lets you anywhere near its intake process.
No licence to operate a records service, but data and tissue handling carry real rules.
Building this outside India? The categories above usually have a local equivalent, so check with your own regulator.
Don't let AI summarise or interpret pathology or imaging for the reviewer. Folioway gives no medical opinion, and that line is what keeps it outside device rules.

Here's what can go south -
I like this for an operator who enjoys process and can run a coordinator team with tight turnaround targets. If you're hoping to build a pure software platform then it is a poor fit. Prove one thing first - you can deliver a complete file, slides included, within 10 days for 30 consecutive patients at one hospital.
Plan for roughly ₹45–85 L, mostly coordinators, tracked courier, ABDM integration and the months spent signing the first cancer hospital.
No sector licence, but you must comply with the DPDP Act, register for ABDM to pull linked records and avoid interpreting clinical content.
Yes, the gathering problem exists almost everywhere. Check local health data law and the rules for shipping tissue samples before you start.

Thinking about building Folioway or something close to it? The hard part is signing the first cancer hospital and hitting a 10-day turnaround on slides. If you need a hand, you know where to find me. Talk to Yash →
