Words You Might Encouter Concerning Prostate Cancer (5)
HEMATOSPERMIA: the occurrence of blood in the semen
HEMATURIA: the occurrence of blood in the urine
HEREDITY: the historical distribution of biological characteristics through a group of related individuals via their DNA
HEREDITARY: inherited from one's parents and earlier generations
HISTOLOGY: the study of the appearance and behavior of tissue, usually carried out under a microscope by a pathologist (who is a physician) or a histologist (who is not necessarily a physician)
HORMONE: biologically active chemicals that are responsible for the development of secondary sexual characteristics
HORMONE THERAPY: the use of hormones, hormone analogs, and certain surgical techniques to treat disease (in this case advanced prostate cancer) either on their own or in combination with other hormones or in combination with other methods of treatment; because prostate cancer is usually dependent on male hormones to grow, hormonal therapy can be an effective means of alleviating symptoms and retarding the development of the disease
HOT FLASH: the sudden sensation of warmth in the face, neck and upper body; a side effect of many forms of hormone therapy
HYPERCALCEMIA: abnormally high concentrations of calcium in the blood, indicating leeching of calcium from bone (tumors raise serum calcium levels by destroying bone or by releasing PTH or a PTH-like substance, osteoclast-activating factor, prostaglandins, and perhaps, a vitamin D-like sterol). Symptoms of hypercalcemia may include drowsiness, lethargy, headaches, depression or apathy, irritability, confusion; weakness, muscle flaccidity, bone pain, pathologic fractures; signs of heart block, cardiac arrest in systole, hypertension; anorexia, nausea, vomiting, constipation, dehydration, polydipsia; renal polyuria, flank pain, and eventually, azotemia (excess of urea or other nitrogenous substances in the blood).
HYPERPLASIA: enlargement of an organ or tissue because of an increase in the number of cells in that organ or tissue; see also BPH
