TCM Local Applications for Cancer Pain Management
Cancer pain takes many forms. It may be caused when a tumor presses on bone, nerves or organs. In addition, certain painful conditions are due to cancer treatment including chemotherapy, radiotherapy and surgery. Sometimes patients may experience headaches and muscle pain that has nothing to do with the illness or treatment. According to TCM understanding, cancer pain can be classified in two major categories.
1. Obstructive pain: this is due to one or several evils attacking an organ or meridian leading to sluggish flows of qi (vital energy) or blood in the region. The pain is usually sharp, relatively localized, and with certain characterisitics. See the "nature of pain". TCM therapies will aim at removing the stagnation so as to resume smooth circulation. 2. Deficient pain: due to the progressive exhaustion of cancerous tissues, the other healthy tissues inside the body generally lack nutrient supply for normal functioning. This always causes dull pain that occurs gradually but persistently and relatively less localized. TCM therapies will aim at nourishing the organs and meridians as well as replenishing blood and qi.
TCM local remedies are mainly targeted on obstructive type of pain. The selected drugs are mostly chosen from insects, worms, living animal parts or toxic substances; TCM holds that these categories can activate blood and qi, removing stasis and coldness, warming meridians and relieving pain. In addition, certain anti-cancer herbs, or herbs with warming and stimulant properties are added to the prescriptions to have more broaden effects. Common ingredients are:

In addition to application on painful areas, these drugs are also applied to specific acupoints on the trunk. It is said that this can promote meridian flow to obtain a general regulating effect, which readjusts neural sensitivity to lower the threshold of pain. Some of the selected acupoints are:
Origin of pain Selected acupoints Nasopharyngeal cancer Da-zhui, feng-chi, fei-shu, shen-que Esophagus cancer Ge-shu, shen-que, Lung or skin cancer Fei-shu, ru-gen, shen-que Liver cancer Qi-men, gan-shu Gall bladder cancer Dan-shu Stomach cancer Wei-shu, zhong-wen, shen-que Intestinal cancer Da-chang-shu, shen-que Pancreatic cancer Pi-shu, shen-que, Cervical cancer Shen-que, shen-shu Bladder cancer Shen-shu, pang-guang-shu, shen-que
Shen-que (umbicius) is an important acupoint in TCM local application.
