How to read the evidence
Evidence tier — overall strength of the evidence for the whole compound
- StrongWell established — backed by strong, consistent human research.
- ModerateSome genuine support, but mostly from small or lower-quality studies. Promising, not proven.
- PreliminaryEarly-stage evidence — a promising hypothesis, not an established effect yet.
- LimitedVery limited evidence — treat this as a hypothesis, not proof.
- InsufficientNot enough good evidence to draw conclusions yet.
Certainty — how sure we can be that the effect is real
- Very highVery sure — strong, consistent evidence
- HighFairly sure — consistent evidence from good studies
- MediumModerately sure — new studies could change this
- LowNot sure — little or mixed evidence
- Very lowVery unsure — almost no usable evidence
Source — where the data comes from
- Meta-analysisPooled analysis of many trials — the strongest evidence
- RCTRandomized controlled trial — a strong human study design
- ClinicalA human clinical study
- Reference knowledgeFrom general health-science or pharmacology references, not a study of this exact claim
- Animal researchStudied in animals, not humans
- Community reportsAggregated user reports — anecdotal signal, not evidence
- TheoreticalMechanism-based reasoning, not yet tested
Study grade — quality of each underlying study (A best, D weakest)
- AHigh-quality — strong, consistent human trials
- BGood — solid evidence with some limitations
- CModerate — limited, small, or mixed-quality studies
- DWeak — preliminary, indirect, or animal-only
Confidence — how strongly the sources back a finding
A 0–100 score from study quality and agreement
Most supplement evidence is graded C–D. Read it as preliminary signal, not proof.
Full write-up
What is it
Lung Cancer is an oncology condition. Research discussed for this condition includes approaches such as Tai Chi, Meditation, Green Tea Extract (EGCG), and Selenium, but these are not interchangeable: findings include clinical research, a review, and laboratory research, with some comparisons made with standard care or standard treatment.
These findings concern particular outcomes and should not be read as a general definition of the condition or as a guarantee of treatment benefit.
Evidence-backed options
The options associated with Lung Cancer span supportive practices, supplements, and laboratory or review-based findings. The clearest clinical signal is for Tai Chi and Meditation as additions to standard care, with reported improvements across wellbeing, sleep, mood, fatigue, physical function, and selected lung-function measures rather than evidence that either treats or removes the cancer itself. Meditation was studied as an 8-week MBSR program in people with NSCLC; the available information does not establish how quickly benefits appeared or provide a treatment dose for Tai Chi.
The supplement evidence is less directly applicable to patient care. Green Tea Extract (EGCG) is supported here by findings from laboratory research, while Selenium and Vitamin C are linked to review-level observations involving lung-cancer risk or treatment-related effects rather than a clearly defined therapeutic course for diagnosed disease. Turkey Tail has been studied as an adjunct, but the supporting information is limited to a pharmacology reference and describes potential survival benefits without specifying a regimen, duration, or onset.
Overall, these options should not be read as interchangeable. Evidence from supportive-care studies in patients does not establish anticancer effectiveness, and laboratory, prevention, or adjunctive findings may not translate directly to an individual with Lung Cancer. Specific doses, schedules, and time to benefit are not established for most options in the information provided. Any consideration of these approaches alongside cancer care warrants discussion with a clinician.
