Embryonal cancer is a type of cancer that primarily affects children and adolescents. The word "embryonal" is spelled with five syllables and pronounced /ɛm.brɪˈjɒn.əl/. The first syllable "em" is pronounced as "em" in "embassy". The second syllable "bryo" is pronounced as "bree-oh". The third syllable "nal" is pronounced as "nal" in "final". The word "cancer" is spelled with two syllables and pronounced /ˈkæn.sər/. The first syllable "can" is pronounced as "can" in "candy". The second syllable "cer" is pronounced as "ser" in "serve".
Embryonal cancer, also known as embryonal neoplasms or embryonal tumors, is a type of cancer that originates from embryonic tissue. It is characterized by the abnormal growth and development of immature (undifferentiated) cells that resemble embryonic cells. This type of cancer primarily affects children and adolescents, although it can occur in individuals of any age.
Embryonal cancer can occur in various parts of the body, including the central nervous system, kidneys (nephroblastoma or Wilms tumor), liver, ovaries, testes, and soft tissues. The tumors associated with embryonal cancer are often highly malignant and tend to grow rapidly, posing a significant risk to the affected individuals.
The exact causes of embryonal cancer are not fully understood, but genetic factors and abnormal development of embryonic tissues are believed to play a role in its development. Symptoms may vary depending on the specific type and location of the tumor, but common signs can include pain, masses or lumps, abdominal swelling, neurological symptoms, and other signs of organ dysfunction.
Treatment for embryonal cancer typically involves a combination of surgery, chemotherapy, and radiation therapy, depending on the specific characteristics and stage of the tumor. The prognosis of embryonal cancer can vary widely, ranging from highly curable to more aggressive and difficult to treat. Early detection and prompt intervention are crucial in order to achieve the best possible outcomes for affected individuals. Regular screenings and medical monitoring may be recommended for individuals with certain genetic predispositions or family history of embryonal cancers.
The word "embryonal" is derived from the Latin word "embryon" meaning "unborn child" or "embryo". It is often used to describe something that is in an early stage of development.
The term "cancer" comes from the Latin word "cancer" which means "crab". It was used to describe tumors because the swollen veins around a tumor reminded early observers of a crab's legs.
Thus, the term "embryonal cancer" refers to a type of cancer that originates from embryonic or immature cells. These are cancers that typically occur in early development or childhood, and are composed of rapidly growing, undifferentiated cells.
