Immunotherapy for Cancers: questions to ask before it is too late
This guide helps patients and families prepare questions. It does not diagnose cancer, recommend treatment, replace your oncology team, or tell anyone to start, stop, delay, or refuse treatment.
Immunotherapy can help some patients greatly and does not help others. Not being offered immunotherapy can be medically appropriate because of cancer type, stage, biomarkers, prior therapy, autoimmune disease, organ transplant, performance status, infection risk, or other health factors.
Immune-related inflammation can affect the lungs, bowel, liver, endocrine glands, skin, kidneys, heart, nervous system, or other organs. Ask which symptoms need same-day advice or emergency care.
The better question: "Is immunotherapy appropriate for my exact cancer type, stage, biomarkers, and current health - and if so, should it be used now?" Start with: "Could biomarker testing change the first treatment choice?"
What is my exact diagnosis, stage, treatment goal, and urgency? Is there enough tissue for biomarker testing?
Which biomarkers are ordered, when will results be back, and could any result change the first treatment choice or trial options?
Who handles prior authorization, copay support, manufacturer assistance, public funding rules, transport, lodging, and financial navigation?
Biomarker testing
Testing can change the first treatment choice
Ask whether tissue testing, blood-based testing, or both are appropriate. Sometimes a repeat biopsy is considered if the original sample is too small or old.
MSI-H, dMMR, and tumor mutational burden can make immunotherapy more relevant in some cancers, including some tissue-agnostic approvals.
In some cancers, especially lung cancer, EGFR, ALK, ROS1, BRAF, RET, MET, NTRK, HER2, KRAS, and related results can affect treatment sequence.
In advanced non-small cell lung cancer, molecular results can be critical before first-line therapy when possible. Some driver mutations point to targeted therapy first, and starting immunotherapy before complete molecular results can lead to the wrong sequence or avoidable toxicity.

Questions to ask before it is too late
The practical question is not "should I get immunotherapy?" It is: "Is immunotherapy appropriate for my exact cancer type, stage, biomarkers and current health - and if so, should it be used now?"
Biomarker results such as PD-L1, MSI/MMR, TMB, NGS and disease-specific driver mutations can change the first treatment choice. In lung cancer especially, molecular results can affect whether immunotherapy should wait.
U.S. checkpoint-inhibitor courses can involve six-figure gross drug spending, while CAR-T and cellular therapies can be several hundred thousand dollars before surrounding care. That is not the patient's bill and not a promise that treatment is suitable.
Drug price is not the same as the patient's bill. In the U.S., branded checkpoint inhibitors can involve roughly $100,000-$250,000 in gross drug spending for a treated patient depending on therapy, duration, discounts and stopping early. CAR-T and cellular therapies can list in the several-hundred-thousand-dollar range before surrounding care. Actual out-of-pocket cost depends on insurance, public funding, hospital contracts, assistance programs, country and clinical choices.
Delays can come from biopsy, pathology, biomarker testing, referral, prior authorization, local access barriers, transport, cost, comorbidities, infections, rapid decline, or poor performance status.
When will biomarker results be back? Is treatment safe to wait for results? Should a major cancer center or tumor board review this? Are trials relevant before starting treatment?
Competition, patent expiry, biosimilars, negotiated prices, public funding decisions, trial access, and patient awareness can affect access over time. None guarantee lower personal cost.

Cost and coverage
Approval is not the same as funding
Immunotherapy access changes frequently. A drug can be approved but not publicly funded, funded only for a precise biomarker or stage, or covered only after standard treatments. Patients should confirm the latest local rules with the treating oncologist, cancer center pharmacist, insurer, public formulary, or hospital financial navigator.
