00 · Why it matters

Why cancer awareness matters

Most changes are not cancer. But knowing what is worth a conversation, what a test can and cannot show, and which questions to ask helps people get the right care sooner. Awareness is about confidence, not fear.

Can OncoGx tell me whether I have cancer?

No. OncoGx is an education and awareness resource. It cannot examine you, diagnose anything or tell you whether a symptom is serious. It can help you understand what you are experiencing and prepare questions for a qualified healthcare professional.

I have a symptom and I'm worried. What should I do?

Many symptoms have causes that are not cancer, but a symptom that is new, lasts more than a few weeks or keeps getting worse deserves a check. Book an appointment with a doctor or health worker. If symptoms are severe or getting worse quickly, such as difficulty breathing, chest pain, heavy bleeding, confusion or fainting, seek emergency care.

What is the difference between screening and a diagnostic test?

Screening tests people who feel well and have no symptoms, to find cancer or pre-cancer early. Diagnostic tests are used when there is a symptom or an abnormal result, to find out what is causing it. If you have a symptom, you need a diagnostic assessment, not a screening appointment.

Is there one blood test that can find all cancers?

Not yet. Multi-cancer early detection blood tests are being studied in large trials. They can miss many cancers, can give false alarms, and have not been shown to reduce cancer deaths. They do not replace recommended screening. Watch our interactive video Can one blood test find cancer early?

Does OncoGx store what I type into the tools?

No. The symptom explorer, screening checklist and question generator run entirely in your browser. We do not send your answers anywhere. Saved items and your theme choice are stored only on your own device and you can clear them at any time.
