The term "chronic myeloid" is used to describe a type of cancer that affects certain blood cells. The word "chronic" means long-lasting or ongoing, while "myeloid" refers to the type of cell that is affected. The spelling of the word can be explained using the International Phonetic Alphabet (IPA) as /ˈkrɒnɪk ˈmaɪəlɔɪd/. The symbol ɪ stands for the short vowel sound in "hit", while the symbol ə represents the schwa sound in "about". This transcription helps to break down the word into its individual sounds, making it easier to understand and pronounce.
Chronic myeloid refers to a medical condition known as chronic myeloid leukemia (CML). This condition is a type of blood cancer characterized by the abnormal growth and proliferation of white blood cells in the bone marrow.
The term "chronic" indicates that CML progresses slowly and may go unnoticed for several years before symptoms appear. "Myeloid" refers to the specific subtype of white blood cells, called myeloid cells, which are affected in this condition. Myeloid cells are responsible for fighting bacterial and fungal infections, as well as regulating the immune system.
In chronic myeloid leukemia, a genetic mutation in the bone marrow cells leads to the production of an abnormal protein called BCR-ABL1. This protein causes an overproduction of immature myeloid cells, known as blast cells. These cells accumulate in the bone marrow and gradually invade the bloodstream, affecting the production of healthy blood cells.
Symptoms of chronic myeloid leukemia may include weakness, fatigue, enlarged spleen, unexplained weight loss, night sweats, and bone pain. Treatment options for chronic myeloid leukemia have significantly improved in recent years, with targeted therapies such as tyrosine kinase inhibitors being the mainstay of management.
Overall, chronic myeloid refers to a specific subtype of leukemia characterized by the slow progression of abnormal myeloid cells in the bone marrow, leading to the disruption of normal blood cell production.
The term "chronic myeloid" is a medical term used to describe a specific type of blood cancer known as chronic myeloid leukemia (CML). The etymology of the term can be understood by breaking it down into its components:
1. Chronic: The word "chronic" comes from the Greek word "khronikos", which means "lasting a long time" or "prolonged". In medical terminology, it is used to describe a condition or disease that persists for an extended period rather than resolving quickly.
2. Myeloid: The word "myeloid" originates from the Greek word "myelos", which means "marrow". In the context of CML, "myeloid" refers to the type of blood cells that are affected by the disease.
