However, six months later at a follow up appointment the patient complained of bone pain in her hips and sternum and her oncologist noticed swollen lymph nodes and ordered a biopsy, CBC, and PET scan. The blood tests identified an abnormally high number of circulating antibodies in the blood and a high blood viscosity (thickness) as a result.
