Acute lymphoblastic leukemia (ALL) signs and symptoms

Signs and symptoms are changes in the body that may indicate disease. A sign is a change that the doctor sees during an examination or on a laboratory test result. A symptom is a change that a patient can see and/or feel.  

A person who has signs or symptoms that suggest the possibility of leukemia is usually referred to a specialist. This is a hematologist-oncologist. A hematologist-oncologist is a doctor who has special training in diagnosing and treating blood cancers such as leukemia, lymphoma, and myeloma. 

It is common for someone with ALL to feel a loss of well-being because of the underproduction of normal blood cells. This happens when the leukemia cells in the bone marrow crowd out the normal blood-making cells. Consequently, patients with ALL do not have a sufficient number of mature red blood cells, white blood cells, and platelets. 

The information on this page covers signs and symptoms of ALL in adults. Visit childhood ALL to learn about signs and symptoms, diagnosis, and treatment information for children with ALL.

  • The appearance of pinhead-sized red spots on the skin, called “petechiae”
