Can routine blood tests find tumors?

Not generally. Most tumors are not diagnosable with routine blood tests. Leukemias are one exception in that a complete blood cell count can provide a strong indication for the diagnosis of some leukemias.
Depends on type. Some routine blood tests may make us think there is something else going on. Almost no routine result will make a doctor immediately leap to the "cancer" diagnosis, but some things can be strange. A white blood cell (WBC) count in excess of 200, 000, for instance. Platelet counts >1, 000, 000. But for actual cancer diagnosis, those take very specific tests looking for specific markers.

Would blood tests show cancerous tumors, or even benign one's in the body? OR Would a regular blood test show indications of cancer / a tumor inside?

Not very helpful. We don't have reliable blood tests to look for the common cancers. Your best bet is cancer surveillance (in your case, I trust you get pap smears if you have ever had someone special), and know the usual warning signs and get seen if they come up. Read more...

Been almost six years since sweating started. How r tumors detected? Blood tests?

Sweating. Sweating is caused by many things. It's impossible to say what you have without knowing more information. You need to find the cause. The first thing is always blood tests.

Oncology: Since no blood tests or scans can identify a single malignant cell it means that people wait til a mass, tumor or lesion form?

Yes. In the future star trek generation, we may have a blood test to identify a single malignant cell or identify a gene marker that will tell us that a cancer ca develop but the ethical question is do you start treating things before they become a problem. Read more...

Limited. Blood tests are not real sensitive in the detection of potential causes of back pain in most cases. Typically, an mri scan allows one to see any potential structural causes to back pain. Tumors in the spine are usually diagnosed in part based on there radio graphic characteristics and then potentially a tissue diagnosis through abiopsy. Thank you for the question. Read more...

Can blood tests indicate the presence of cancer? I am quite worried that I have cancer, however I have had numerous blood tests (full cbc with diff, tumor marker, thyroid, etc) all coming back normal

Blood test . The only true and diagnostic way of telling if you have cancer is not by blood test, images, CT scans. The only way is by biopsy of the tissue of concern either by CT guided, FNA, or surgical resection. By doing this a pathologist can determine the severity and aggressiveness of the cancer and specifically the type of cancer so an oncologist can modify chemotherapy to target the cancer type. .
