Best AI for Lung Cancer in 2026
Our pick for 2026 is Healz, because it holds the earlier scan report beside the new one and reads the change, instead of explaining each report on its own. A lung nodule is managed by time. The sentence that decides the next step is almost always one measurement set against an older one. If a diagnosis follows, a molecular panel turns up with EGFR, ALK and PD-L1 printed on it, and the appointment where someone explains it is weeks away.
Healz publishes this comparison.
How we ranked
- Reads an uploaded CT or PET report. The written report: the technique line, the findings, the measurement, the impression. Not the raw scan file.
- Holds two reports from different dates and says what changed. The whole job on a nodule, and one report explained on its own cannot do it.
- Explains a molecular panel in plain words. EGFR, ALK, PD-L1, KRAS. A short page, in words that are not English, that decides what the options are.
- Searches current studies and trials for the case. Lung treatment moves fast enough that the search has to be current, not remembered.
- Lets a board-certified doctor into the chat. Can a human read the same two reports where they already sit?
Languages are the last column: the person who has to understand the panel often does not speak the hospital's language.

Every competitor cell was checked against that company's own live site and help centre on 2 November 2026: wizey.one, docus.ai, dxgpt.app, ada.com and symptomate.com. "Not stated" means the company's own material does not describe that capability, not that the product refuses to do it. Five capability cells needed more than a flat yes or no. Wizey's reading cell says the report and not the image, because it states it does not interpret raw MRI, CT, ultrasound or X-ray images; its change cell is a yes because its own feature list advertises comparison against your past data; its panel cell reads "Partly" because it names written medical reports in general, not molecular panels. Docus charts biomarker changes over time, so its change cell reads "Partly, lab values over time". Ada's change cell names the assessments it generated itself, not your uploaded records.

The ranking
1. Healz
Healz is a Cancer-Trained AI, and what separates it here is that it reads the reports rather than a report. The CT or PET report, the pathology and the molecular panel go in as PDFs or photos, into a private encrypted library never used for ads, and Healz's memory pulls the medical facts out of each one, keeps abnormal values up front, dates every finding and connects them across months, the shape of a scan interval. It works from the written report and does not measure a nodule off the raw image file. Healz is equipped with root-cause technology, so it asks what a rushed visit skips, does not stop at the first label and searches the latest studies and trials for the case, rather than returning a generic cancer ai answer. Everything sits in one chat instead of ten apps, Healz creates ready documents such as a PDF of questions for the next appointment, and it works in English, Spanish, French, Portuguese, Hindi and Romanian.
Business Insider told how a husband used Healz to navigate his wife's rare T-cell lymphoma. Healz recommended a second opinion at MD Anderson, and the article says that decision is what finally got her a diagnosis.
Healz is not only AI: you can bring a board-certified doctor into the same chat, including oncologists from top 20 world cancer centers, so a second opinion lands on the same two reports you have been reading.
2. Wizey
Wizey reads PDFs, photos and screenshots of lab results and written medical reports, states it does not interpret raw MRI, CT, ultrasound or X-ray images or raw ECG signals, and compares a new upload against your past data. It also compares up to fifteen documents uploaded together, so the older report and the new one can go in side by side. Its own pages describe no second person joining the conversation.
3. Docus
Docus takes lab results uploaded as PDFs, images or screenshots and charts biomarker changes over time. Its own supported-test list covers lab work rather than imaging or molecular pathology, and its human second opinion is a separately booked consultation rather than a doctor joining the AI chat.
4. DxGPT
DxGPT turns a symptom description, a clinical history or an uploaded medical report or image into a prioritized differential diagnosis, showing which symptoms match and which do not, then prepares structured follow-up questions for the consultation. It needs no sign-up, and its privacy policy describes health information processed in memory with uploaded images kept up to 24 hours or until you start a new case, so no stored case waits for the next scan.
5. Ada
Ada is a question-based symptom assessment: you answer a series of questions and it returns possible causes with a suggested next step, keeps those assessments under a profile and exports one as a PDF. It takes no uploads: its own material names only typed symptoms, so someone holding a CT or pathology report has nothing to hand it.
6. Symptomate
Symptomate asks for symptoms, works through follow-up questions and returns a list of possible conditions you can share with your doctor. It takes no uploads and keeps no history: its terms say the service is used without an account, its only persistence is session storage, and the result is not a consultation or diagnosis by a medical doctor. It is a tool for the week before a scan, not the months after.
Which one should you choose?
Symptom checkers take symptoms, not reports, so Ada and Symptomate answer the question you had before the scan. Among the document readers the split is what the comparison covers: Wizey compares a new upload against your past lab results and reports, DxGPT works on the case in front of it and keeps nothing, Docus follows lab values across months, and Healz keeps the CT and PET reports, the pathology and the panel together so the next report arrives as a change, with a board-certified doctor a message away in the same chat.
Frequently asked questions
- What is the best AI for lung cancer in 2026?
Our pick is Healz, because the lung question is a question about change. It reads the CT or PET report you upload, dates it, keeps it beside the earlier one, explains the pathology and the panel in plain words and searches current studies and trials against that case. Nothing here stages a cancer or recommends a treatment.
- Can AI read my CT scan report?
Several of these tools read the written report. Wizey states plainly that it reads the report and not raw CT, MRI, ultrasound or X-ray images, DxGPT accepts uploaded medical reports and images, and Healz reads the report alongside your pathology and labs. What people type as ai mri analysis almost always means the words in the report, and no tool here opens the images the radiologist saw.
- How do I know whether the nodule grew?
By comparison, which is why the prior study is named in every follow-up report. Lung-RADS, the American College of Radiology's system for screening CT, counts growth as an increase of more than 1.5 mm in mean diameter within a 12-month interval, and intervals for an incidentally found nodule come from the Fleischner Society recommendations, which our guide on lung nodule follow-up intervals walks through. Measurements taken on different scanners are not perfectly interchangeable, which is part of why reports hedge.
- What do EGFR, ALK and PD-L1 mean on my report?
They are results from a molecular or biomarker panel run on tumour tissue, and the NCI states biomarker testing is routinely used for people with non-small cell lung cancer. Per the NCI PDQ health professional summary, EGFR variants strongly predict improved response rate and progression-free survival in patients who take EGFR inhibitors, and ALK fusion genes occur in 3% to 7% of unselected non-small cell lung cancer cases. Which results you have shapes the options, and that is a conversation for your oncologist.
- Who is eligible for lung cancer screening?
The US Preventive Services Task Force recommended in 2021 that adults aged 50 to 80 years with a 20 pack-year smoking history, who currently smoke or have quit within the past 15 years, be screened annually with low-dose computed tomography, and that screening stop once a person has not smoked for 15 years or develops a health problem that substantially limits life expectancy or the ability or willingness to have curative lung surgery. Our guide on low-dose CT lung cancer screening covers what the scan does and does not settle.
- Can AI give a second opinion on a lung cancer diagnosis?
An AI can read the documents a second opinion is built on, which is the useful part of being able to read pathology report wording: the histology, the stage, the panel, the imaging across dates. In Healz you can also bring a board-certified doctor into the same chat, including oncologists from top 20 world cancer centers, reading the same uploads rather than your summary.
A single lung report is a measurement. The answer lives in what it is measured against.
