How to Obtain the Greatest Chemotherapy Drug
Cancer refers to the uncontrolled growth of cells combined with malignant behavior – invasion and metastasis. The cause for this disease is believed to be the interaction of environmental toxins and the genetic susceptibility. Basically, the principle that makes a chemotherapy drug functional is the impairment of the cellular division of tissues with a fast growth rate. The fact that these drugs destroy cells leads to their being named cytotoxic.
In broad general terms, chemotherapy kills cells by means of chemical substances. Particularly speaking, chemotherapy is used to kill the cells of micro-organisms or cancer. Chemotherapy usually refers to antineoplastic drugs which are used to treat cancer or to the combination of these drugs into a cytotoxic standardized treatment regimen. Besides the reference to cancer treatment, chemotherapy also has an antibacterial dimension when it involves the use of antibiotics.
A chemotherapy drug, or better a combination of such drugs, functions by destroying cells that divide quickly. Unfortunately, these drugs cannot make a selection between normal fast-dividing body cells and cancer cells. These other cells that get attacked by a chemotherapy drug are digestive tract linings, the bone marrow and the hair follicles. Thus, the main side effects of chemotherapy will include hair loss, the inflammation of the digestive tract and the reduced production of blood cells.
Among the other uses of the chemotherapy drug and cytostatic chemotherapy agents there are the treatment of autoimmune diseases (multiple sclerosis, rheumatoid arthritis) and the suppression of transplant rejections. There are newer anti-cancer drugs which were designed to act directly against abnormal proteins in cancer cells; this treatment option is known as targeted therapy.
When talking about a chemotherapy drug, we should be aware that there are different types available at present. Thus there are antimetabolites, alkylating agents, topoisomerase inhibitors, anthracyclines and several others. While all these chemicals interfere with the DNA structure, there are newer and revolutionary medicines like the tyrosine kinase inhibitors or the monoclonal antibodies that leave the nucleic acids unaffected.
These ones target a molecular abnormality in particular types of cancer such as chronic myelogenous leukemia or gastrointestinal stromal tumors. More special chemotherapy drug options only change the behavior of the tumor cells without affecting other tissues. From these so-called adjuvant therapies, the hormone treatment will be commonly used. The decision to administer only one chemotherapy drug or a combination of several medicines belongs to the doctor and it is taken depending on the stage of the disease and the purpose of the treatment.
