Without nucleotides, the cell cannot replicate, cannot repair its DNA, and is incapable of synthesizing new proteins. Examples of these drugs are methotrexate, mercaptopurine, and fluorouracil. DRUGS THAT DAMAGE THE MITOTIC SPINDLE The mitotic spindle is a collection of microtubules that serve to carry the chromosomes to opposite poles of a dividing cell. Disruption of the spindle is an effective way of blocking cell division. Drugs in this class include Vinblastine, Vincristine, and Taxol. DRUGS THAT BLOCK HORMONE RECEPTORS Breast cancer may be caused by the lifelong exposure of breast cells to the growthstimulating effects of the female steroid hormone, estrogen.
Blood that is positive for PSA is strong evidence of prostate cancer. This test is sometimes followed up with a biopsy and ultrasonography. 16 Cancer STAGING At stage I, the tumor cannot be felt during a rectal exam and there is no evidence that it has spread beyond the prostate. At stage II, the tumor is large enough to be felt during a rectal exam, but is still noninvasive. By stage III, the cancer has spread outside the prostate to nearby tissues, and at stage IV, cancer cells have colonized the lymph nodes and many other parts of the body.
The carcinogens’ combined ability to form DNA adducts and to force a cell to divide when it should not accelerates the mutation rate and onset of cancers. An accelerated mutation rate increases the risk of damaging a tumor suppressor gene or of activating an oncogene. These changes set the stage for serious trouble to come. S. cancer deaths. Smokers are 20 times more likely to die of cancer than nonsmokers. Worldwide, 4 million people die every year of cancers caused by tobacco smoke. In China, where two-thirds of the adult male population smokes tobacco, close to 1 million die each year of tobacco-related cancers.
