What makes radioisotopes so valuable is that they can be used selectively. Isotopes of iodine, for example, incorporate in the thyroid gland, where they can be used in both the detection and treatment of cancer, in some cases even eliminating the need for surgery. Fluorine, a related element, has a radioactive isotope (F18) that concentrates in bones, facilitating the detection of bone cancers...
...hidden in the pelvic cavity of the lower abdomen. Before recent technical advances they were relatively difficult for the surgeon to reach. In the man, a tube called the vas deferens (literally, the "carrying-away vessel") arises from each testicle to carry the spermatozoa to the prostate gland where the seminal fluid is finally compounded for ejaculation through the urethra. Near its origin in the scrotum, the vas deferens is readily accessible to the surgeon's scalpel...
...result of uncommon-sense reasoning, doctors are inducing early abortions with prostaglandin F2 alpha, a hormone-like substance derived from semen. The prostaglandins are a class of chemicals, 16 of which have now been isolated, that were originally believed to be secreted in the prostate gland. The first were found in human semen, which is still the richest source known. Now prostaglandins are known to occur in many other human tissues and in menstrual fluid. They are also found in the semen of sheep, and it was from the seminal vesicles of rams that medical researchers obtained their early supplies...
