People with chronic lymphocytic leukemia are at increased risk of developing certain infections or a secondary cancer.
From the symptoms and signs she has, seems like she is in advanced phases of leukemia (shortness of breath is caused by shortage of red blood cells; frequent infections-sinus infection are often because the white blood cells aren't functioning properly; easy bleeding and bruising, including frequent or severe nosebleeds, bleeding from the gums, or tiny red marks caused by bleeding into the skin are due to a shortage of blood platelets)
Does she feel bone and joint pain?
Is she having swelling of the liver and spleen, and enlargement of the lymph nodes in the neck, underarm, stomach or groin?
Doctor typically examines blood or bone marrow samples under a microscope and classifies blood cells into specific types based on their size, shape and other features. This helps establish the type and subtype of leukemia.
