Does Lymphoma Show Up in Blood Work? What a CBC Can and Cannot Show

Routine blood work cannot diagnose or rule out lymphoma. A complete blood count is often normal in lymphoma, even in aggressive types. Some results, such as anemia, low or high white cells, high LDH or a high ESR, can prompt a closer look, but each has far more common causes. Lymphoma is diagnosed with a biopsy, usually of a lymph node.

Is Low Hemoglobin a Sign of Cancer? What a Low Result Usually Means

Low hemoglobin is usually not a sign of cancer. Iron deficiency is the most common cause of anemia, and most iron deficiency comes from diet, menstrual blood loss or pregnancy. Cancer can lower hemoglobin through slow bleeding in the gut or by crowding the bone marrow, and the rest of your blood count, ferritin and a few follow-up tests show which pattern you have.

Is High Calcium a Sign of Cancer? What a High Result Usually Means

High calcium on routine blood work is usually not cancer. An overactive parathyroid gland is the most common cause, and cancer that raises calcium is usually already advanced and causing other symptoms. Parathyroid hormone (PTH), measured with calcium, is the test that separates the two.

Is Low Potassium a Sign of Cancer? Low and High Potassium Explained

Low potassium is rarely a sign of cancer. Diuretics, vomiting, diarrhea, laxatives, low magnesium and aldosterone excess explain most low results.
