Detecting Cancer Early With Screenings

Cancer is a major medical issue with thousands of cases being diagnosed each year. Screening for cancer is complicated. A doctor may order a biopsy or conduct a urinalysis. However, they also may order a blood test.

Can a Blood Test Detect Cancer?

A blood test does not always yield a definitive diagnosis unless the specific disease is a cancer of the blood. Nonetheless, using a blood test as the first step in the screening process can reveal important clues about the patient’s condition. It may be that the ultimate diagnosis will not be cancer when the screening is complete.

Clues From Cancer Screening

When a screening by blood test is ordered, the results may show cancer cells in the blood. They also may reveal proteins or other byproducts of the disease in the blood. Essentially, this screening demonstrates how and whether internal organs are being affected by the disease.

Which Cancer Blood Test Will Be Used?

A lab may run a number of screening tests, including one for a complete blood count, which is used to measure the type and number of blood cells in a sample. The presence of abnormal cells or too many or too few cells can indicate a diagnosis. Similarly, blood protein testing can detect the presence of immune system proteins that are abnormal.

Further Screening

Doctors rarely make a cancer diagnosis based solely on a blood test. Instead, they may use a bone marrow biopsy and other screenings to make a definitive diagnosis. Regardless, it is imperative to have a blood test performed by a reputable laboratory facility to ensure the accuracy of the results.

Early detection and treatment are crucial when it comes to surviving cancer. Undergoing a blood test and other necessary screenings at the first signs of the disease is critical.
