Q: What is Healz and how did it help the Atlanta doctor’s wife? A: Healz is a healthcare chatbot and an AI assistant for cancer patients designed to help users navigate diagnosis, treatment, and recovery; it launched in beta last year. In the Atlanta case it helped the family track symptoms and records and encouraged a second opinion at MD Anderson that led to a rare T‑cell lymphoma diagnosis. Q: What practical tasks can an AI assistant for cancer patients perform? A: An AI assistant for cancer patients can collect and summarize labs, imaging, pathology reports, and notes, prompt follow‑up questions, flag when a second opinion or specialty center makes sense, help find oncologists and clinical programs by subtype, translate reports into plain language, and prep one‑page visit briefs and question lists. It can also help compare treatment options and track side effects, but its recommendations should be verified with your care team. Q: How does Healz handle large sets of medical records and documents? A: Healz layers workflows and a memory system on top of existing models to digest and store large volumes of medical files, and the founders say some users have uploaded over 1,500 documents. The tool can build timelines, reconcile duplicate records, and produce summaries to reduce the chaos that slows care. Q: What is Healz’s “root‑cause mode” and why does it matter? A: “Root‑cause mode” prompts the model to ask up to 20 follow‑up questions about a user’s symptoms before drawing conclusions or making suggestions, which is intended to avoid overly agreeable answers. That deeper questioning helps surface missing details and leads to more cautious, focused guidance rather than immediate definitive conclusions. Q: How should patients use an AI assistant for cancer patients alongside their clinicians? A: Use an AI assistant for cancer patients as a supplement, not a replacement, and bring app‑generated summaries or a short visit brief to appointments so clinicians see the same information. Ask the app for citations or guideline references you can share, and confirm dosing, monitoring plans, and any treatment recommendations with your oncologist. Escalate urgent symptoms to a clinic or 911 rather than relying on the app. Q: What accuracy and privacy limits should users be aware of? A: These tools cannot examine you and have known accuracy limits, with the Atlanta family noting a few misses on treatment specifics, so human oversight is essential. Review each app’s privacy policy and data‑storage practices — look for encryption, access logs, and deletion controls — and always verify dosing and monitoring plans with your care team. Q: How do I get started with an AI assistant for cancer patients? A: Set up a secure account, enter your diagnosis or symptoms, and upload PDFs, scans, lab results, and lists of current medicines and allergies so the tool can build accurate summaries. If available, test a free tier first with non‑sensitive items to see if summaries match your records before uploading full medical files. Q: Is Healz gaining traction and who is backing the startup? A: Healz launched in beta and reported about $100,000 in annual recurring revenue by early September after recurring revenue doubled month to month over the summer, with the founders saying most users are patients (about 97%) and month‑to‑month retention near 70%. The company has drawn investor interest, including backing from Alexey Dosovitskiy of Recursive Superintelligence.
