Local applications of medicinal substances mean that the active ingredients of certain preparations are absorbed through the skin and then onto the cancer site. Through the slow absorption process, there is less risk to develop general poisoning reactions, it also enables drugs to bypass the interference from the kidney and liver as well as avoid adverse stimulation on the intestinal tract. During application, physicians will change the base constantly so as to avoid local reactions like itchiness and rashes appearing.
