How can blood tests be used to determine which site (bone marrow or lymph nodes) has cancer tumours?

The site of the cancer is important but the info in the link below is invaluable. I do not care about points but the info could save your life.

To find the cause of symptoms, the doctor asks about the patient's medical history, does a physical exam, and may order laboratory studies. The patient may also have one or all of the following exams:\n\nFecal occult blood test \nUpper GI series \nGastroscopic exam \nAbnormal tissue seen in a gastroscope examination will be biopsied by the surgeon or gastroenterologist. This tissue is then sent to a pathologist for histological examination under a microscope to check for the presence of cancerous cells. A biopsy, with subsequent histological analysis, is the only sure way to confirm the presence of cancer cells.\n\nTreatment\nTreatment is usually adapted to fit each patient's individual needs and depends on the size, location, and extent of the tumor, the stage of the disease, the patient's general health and other factors.\n\nMany patients with cancer are motivated to learn all they can about the disease and their treatment choices so they can take an active part in decisions about their medical care. The doctor is the best person to answer questions about their diagnosis and treatment plan.

white blood cells, which is why when someone has bone cancer their white cell count drops

All you need is to be in pretty goo d health.  If you're in the UK you register through the blood donation service - go down to see them, tell them you'd like to go on the bone marrow register.  They make sure you're healthy, check your blood type and add you to the register.  This doesn't mean you'll ever donate, if someone needs bone marrow they check the register and contact potential matches, they then check all those matches to see who comes closest - but they give you all that info at the blood donation centre.

Basically, you'll first do blood tests and stuff (real simple) to see if you match him closely enough genetically for it to be feasible (if it's not a good match, it will cause problems.  Once a match is found, they'll give your nephew really high doses of chemo to get him into a temporary remission.  The chemo is so strong that the body cannot recover from it on its own.  With the BMT, however, the new, stronger, bone marrow can help him recover once he receives it via an IV.\nYour part in it would be, of course, the initial blood test first.  Then, if you were a match, you would have your marrow harvested from the back of the pelvic bone (this hurts really badly, but is worth it and it doesn't last too long).  That marrow then goes to your nephew.

It's useful to detect bone invasion of the cancer (usually prostat)

You could measure the level of glycosylated hemoglobin. Assuming the level of glucose is relatively steady (NOT a diabetic), the level of Glycosylated HgB will be a function of the length of time the RBC was in circulation. Higher level, older the RBC.

Adding to the above answer, make sure that a "morphology" study is done.  This is where they take the cells and directly look at them.  "Morphology" refers to the shape and size of different cells in your blood -- this is an important sign of cancer and other diseases of blood.\n\nCBC was traditionally done by counting a sub-sample under a microscope, but is now often done by machines, so morphology may not be looked at unless your doctor specifies it.

You can use a variety of things. Normally we will test it with this protein substance called luminol; they even have preswabbed cotton buds to test for it on scene. However if you do with for a more accurate measure what they normally do is they go to the mobile field lab and test it with RH-Antibodies.

Your son has lymphoblasts in his blood, they should only be in his bone marrow.  When there is leukaemia, there is an overload of the immature white cells, when they run out of room in the bone marrow, they spill into the blood stream. The cancer cause the white cell to never mature, so it never does its job of fighting infections. Although the blood test may show high levels of white cells, these are cancerous cells.\n\nBone marrow biopsy is done to confirm

blood tests can determine any and all infections but there are very many different tests for different reasons\npathology  department will need to know in what infection area to check\nin  u.k.  ---  ear- nose and throat  [ e.n.t] is a specialist  area and can diagnose inner ear problems  often without blood tests\nbe  well

They look at your HLA types...\n\nThese are molecules "advanced" that are present in one's DNA, that rearrange to make antibodies. There are three classes, HLA-A, B, and C.\n\nThere are many types within each class, and so they look for a match which has the closest similarity (along with blood type) to the individual who needs bone marrow.

The only way to know is if she takes a test - either an antibody test or a blood test. There's no other way for you to make a diagnosis, just like you couldn't diagnose if she had cancer.\n\nOnce she does take this test, there are tons of sites with information about AIDS. But I suggest that you first get her to take the test.\n\nGood luck

As with all acute leukemias, acute lymphoblastic leukemia is characterized by proliferation of blasts (lymphoblasts) in the bone marrow. Commonly the peripheral blood and other organs are involved.\n\nThe initial laboratory evaluation of a suspected leukemia requires a complete blood count (CBC) including a platelet count and an examination of a peripheral blood smear.\n\nAlthough the white blood cell count (WBCc) is typically thought of as being greatly increased in leukemia, the WBCc is really highly variable, ranging from severe leukopenia to extreme leukocytosis.\n\nThe platelet count is generally decreased in acute leukemias, but is often normal in chronic leukemias.\n\nThe hematocrit and hemoglobin usually reflect a normocytic/normochromic anemia.\n\nThe diagnosis and clasification of leukemia is accomplished largely through the laboratory examination of peripheral blood and bone marrow.\n\nThe principle studies include:\n\nMorphology \nperipheral blood smear \nbone marrow aspirate & biopsy \nCytochemistry \nGenetic analyses-chromosomal and molecular \nImmunology

You would need a biopsy to know.  Cancer will kill you, so find out.  Caught early enough, surgery can cure a cancer.

Hi,\n\nFirst you need to register and get screened.  this starts with some forms, questionnaire and health screen then a simple blood test.  Besides Marrow donation,  you can also donate "peripheral" blood cells - such as platelets, stem cells and plasma; these help other types of cancers and blood problems.\n\nThere are a number of "factors" in  the blood that make you a match for someone.  Your information will be put in a large data base and if someone needs a marrow transplant ( blood cancers are a big cause to need one)  you will get called to go in and make a donation if you match a bunch of these factors,  the more factors you have in common the better chance the transplant will be successful.\n\nIn advance;  THANK YOU  it is really scary to need a transplant and they put your info into the 'puter and no matches come out so you wait and hope for a match.  The more people in the database, the more chances that if you need a transplant it will be available.\n\nI am very fortunate that I don't need one yet [have Myeloma];  but if that day comes,  you may be my match.\n\nGood luck,\n\nJewells\n27 month survivor and still going strong

Yes.  To be more explicit, the oncologist may tell you if it is in the small intestine, or the large intestine.
