Question

Hey, I was just wondering, can a blood test reveal cancer?

Please Help

Answer 1

Quoting my source:

"Blood tests alone can rarely, if ever, show the presence or absence of cancer. If your doctor suspects you may have cancer, he or she may order certain cancer blood tests or other laboratory tests, such as an analysis of your urine, to help guide the diagnosis."

Short answer, no.

Answer 2

If they are looking for blood based cancers.

If it is just a basic check, then no.

Answer 3

Yes, it can.

Answer 4

There really isn't any single test to detect all cancers and general blood tests cannot usually identify cancer unless a request was made to check for specific markers that could be associated with a particular type of cancer. Usually an analysis of other symptoms along with a range of blood tests may confirm that there is something not quite right, which may require further detailed tests and evaluations. This may include X-Rays, CT, MRI or PET scans.

A general blood test such as a Full Blood Count can however provide a lot of information, which in conjunction with other symptoms may establish the need for more specific tests that could identify the particular ailment more precisely.

FBC measures include;

- the amount of haemoglobin in the blood;

- the number of red blood cells (red cell count);

- the percentage of blood cells as a proportion of the total

blood volume (haematocrit or packed cell volume);

- the volume of red blood cells (mean cell volume);

- the average amount of haemoglobin in the red blood cells (known as mean cell haemoglobin);

- the number of white blood cells (white cell count);

- the percentages of the different types of white blood cells (leucocyte differential count); and

- the number of platelets.

Answer 8

I think it can only identify some cancers not all of them.

Yes, it can be an indicator.  If your white count is down for instance it could be a sign of leukemia.
