The short explanation
Usually not, at least not as advertised. Tumour marker blood tests such as CA-125, CEA or CA 15-3 are not reliable for screening healthy people without symptoms. They can be raised for many harmless reasons, leading to worry, repeat tests and scans, and they can also be normal when cancer is present. Medical guidelines do not recommend them for routine screening. The screening tests that do have good evidence for women are more specific: cervical screening with a Pap or HPV test, breast screening with clinical examination and mammograms at the appropriate age, mouth examination for tobacco users, and bowel screening from middle age or earlier with a family history. A doctor can advise which of these suit you.
What depends on your situation
The parts of this that change from woman to woman. Uncertainty is stated, not hidden.
- Packages can be useful for checking things like blood sugar, cholesterol and blood count, but these are different from cancer screening.
- If you have symptoms or a strong family history, a doctor may order specific tests, which is different from a general package.
- Government facilities offer free screening for mouth, breast and cervical cancer.
What this answer cannot determine
The boundary of online education. These need a clinician who can see you.
- This cannot tell you which tests are right for you. A doctor can advise based on your age and history.
Questions for your clinician

- Which cancer screening tests are recommended for someone my age?
- Do I need any tumour marker tests?
- Does my family history change what I should have?
