Leukemia
Leucemia
What it means
Leukemia is a term for cancers of the blood cells. It starts in blood-forming tissues such as the bone marrow. In leukemia the bone marrow makes large numbers of abnormal cells, most often white blood cells; they build up in the bone marrow and blood and crowd out the healthy blood cells. Which type of leukemia a person has depends on the type of blood cell that becomes cancer and whether it grows quickly or slowly: acute leukemia is fast growing and chronic leukemia is slow growing. Symptoms may include feeling tired, fever or night sweats, easy bruising or bleeding, and weight loss or loss of appetite. Blood tests, such as a complete blood count, and bone marrow tests are among the tools used to diagnose it.

Leucemia is the title of the MedlinePlus en español page and the headword in the Real Academia Española dictionary, which marks it as a feminine noun: la leucemia. The dictionary defines leucemia as a neoplastic disease of the organs that form blood cells, characterized by the malignant proliferation of leucocitos. The National Cancer Institute's Spanish dictionary entry for leucemia calls the abnormal blood cells glóbulos anormales.
MedlinePlus en español names the two growth patterns leucemia aguda (fast growing) and leucemia crónica (slow growing), and gives the main types as leucemia linfocítica aguda, leucemia mielógena aguda, leucemia linfocítica crónica and leucemia mielógena crónica. Words that appear with the term are médula ósea (bone marrow), glóbulos blancos (white blood cells), plaquetas (platelets), moretones (bruises) and conteo sanguíneo completo (complete blood count).
