Frequently Asked Questions

Is Cancer Insight a medical advice website?

No.

Cancer Insight is designed for educational and research-exploration purposes only.

It does not provide diagnosis, individualized treatment recommendations, professional medical advice, or healthcare services.

Where does the research information come from?

Cancer Insight may use research information from sources including PubMed, PubMed Central, NCBI resources, DOI records, scientific publisher pages, and related research metadata.

Scientific images may also come from sources such as Wikimedia Commons.

What is PubMed?

PubMed is a database and search resource for biomedical and life-sciences literature maintained by the U.S. National Library of Medicine.

Cancer Insight may use PubMed information to display research titles, abstracts, journals, authors, publication dates, publication types, and source links.

What is PubMed Central?

PubMed Central, often called PMC, is a digital archive of full-text biomedical and life-sciences journal literature.

When Cancer Insight identifies a freely readable PMC version of a paper, the paper may be labeled “Free full text in PMC.”

Does “Free full text” mean I can reuse the paper?

Not necessarily.

Free full-text availability means the paper can be read without a normal paywall at the identified source.

Copyright and reuse permissions depend on the paper's original license and publisher terms.

Why do some papers have abstracts and others do not?

Abstract availability depends on the metadata provided by the research source.

Some papers may have a PubMed abstract while others may only provide title, journal, date, author, or source-link information.

What are study-type labels?

Cancer Insight may display publication-type labels from research metadata.

Examples include:

• Clinical Trial,
• Randomized Controlled Trial,
• Review,
• Systematic Review, and
• Meta-analysis.

These labels depend on the information available from the original research source.

Does a study-type label tell me which paper is best?

No.

A publication type describes the type of research record. It does not by itself determine study quality, reliability, certainty of evidence, clinical usefulness, or relevance to an individual patient.

How does the Study Type filter work?

The Study Type filter checks available publication-type metadata and displays papers matching the selected category.

A paper without the required publication-type metadata may not appear when a study-type filter is active.

How do the From Year and To Year filters work?

Cancer Insight extracts a publication year from available publication-date metadata.

The From Year filter keeps papers published in or after the selected year.

The To Year filter keeps papers published in or before the selected year.

Papers without a recognizable publication year may not appear while year filters are active.

Can I search within the papers that were found?

Yes.

The Research Papers page includes a filter that can search across available titles, abstracts, journal information, study-type metadata, and related research terms.

What does “Why this paper is relevant” mean?

Cancer Insight may show a short explanation based on information already available in the research record.

This may use the paper title, abstract, treatment tags, publication type, and the current cancer search.

It is a navigation aid, not an independent scientific conclusion, quality rating, or medical recommendation.

What does “Treatments mentioned” mean?

It means Cancer Insight identified one or more treatment categories associated with the paper or research record.

A treatment mention does not mean that a treatment is recommended, proven effective, safe, or suitable for a specific person.

What is Treatment Research?

Treatment Research lets users focus on research associated with one treatment category for the cancer currently being explored.

Cancer Insight may combine treatment-tagged papers from the original cancer search with additional PubMed evidence.

Duplicate papers are removed from research counts where possible.

What does Compare Treatments do?

Compare Treatments examines research coverage for two selected treatment categories.

It may compare measures such as:

• unique-paper counts,
• free full-text availability,
• latest publication year,
• journal coverage,
• clinical-trial counts,
• review counts, and
• meta-analysis counts.

It compares research literature, not which treatment is medically better.

Why are the papers different on the two sides of Compare Treatments?

The two treatment searches are performed independently.

Cancer Insight does not artificially pair one paper from one treatment with one paper from another treatment.

Each side shows supporting PubMed evidence for that treatment category.

Why can treatment paper counts be different?

Different treatment categories may return different amounts of research literature.

Counts can also vary because of search terms, source metadata, publication indexing, treatment tags, deduplication, and the current retrieved dataset.

A larger count does not mean a treatment is better or more effective.

How does Cancer Insight remove duplicate papers?

Cancer Insight attempts to identify duplicate research records using available identifiers such as PubMed IDs, DOI values, titles, or other metadata.

Duplicate records are removed from research counts where possible.

Some duplicates may remain if identifiers are missing or inconsistent.

What does Research Analytics show?

Research Analytics summarizes characteristics of the currently retrieved research dataset.

Depending on the available data, this may include:

• unique-paper counts,
• free full-text counts,
• latest publication year,
• journal coverage,
• clinical-trial counts,
• treatment coverage,
• publication-year trends, and
• top journals.

Does a larger bar in Research Analytics mean better evidence?

No.

Analytics bars describe the amount or distribution of retrieved research information.

They do not measure treatment effectiveness, safety, quality, or medical importance.

What are Cancer Images?

Cancer Images are scientific or medically relevant images retrieved from external sources such as Wikimedia Commons.

Cancer Insight may prioritize material such as pathology, histology, microscopy, MRI, CT, specimens, medical diagrams, or segmentation images.

Can I reuse images from Cancer Insight?

You should check the original source first.

Cancer Insight may display available creator and license information, but reuse rights depend on the original image license.

Can I download a research report?

Yes.

Cancer Insight can generate PDF research reports based on the current research dataset or filtered research set.

Reports may include research metrics, treatment coverage, study-type information, paper metadata, abstract excerpts, and links to original sources.

Can I export the research data?

Yes.

Cancer Insight can export research-paper data and certain analytics as CSV files.

CSV files are intended to make the retrieved research information easier to organize or analyze.

Can I save papers?

Yes.

Papers can be saved while browsing Cancer Insight.

Saved-paper preferences are stored locally in the browser, so they normally remain available on the same browser and device.

Why did my saved papers disappear?

Saved-paper information is stored locally in the browser.

Clearing browser data, using private browsing, switching browsers, or using another device may remove or hide saved papers.

Does Cancer Insight contain every relevant cancer paper?

No.

Cancer Insight displays research returned by its search and retrieval process.

Some relevant papers may not appear because of search limits, indexing, metadata availability, database changes, source availability, or other technical factors.

Can Cancer Insight research results change over time?

Yes.

Research databases continue to change as new papers are published, metadata is updated, records are corrected, and external services change.

Cancer Insight itself may also improve its search, filtering, and processing methods.

Why might a paper have missing information?

Cancer Insight depends on available source metadata.

Some records may not include an abstract, publication type, DOI, PMC link, author list, treatment tag, or other information.

What should I do if a source link is broken or information looks wrong?

You can report the problem through the Cancer Insight contact page.

Including the paper title, cancer type, or broken source information can help identify the problem.

Can I ask Cancer Insight a personal medical question?

Cancer Insight is not designed to provide personal medical guidance.

Do not enter private health records or other sensitive personal information into research search fields.

Personal medical questions should be discussed with a qualified healthcare professional.
