Unfold, from a Chinese medical perspective, cancer, cancer treatments, and the role of jing. Cancer is a disease defined in Western biomedical terms, yet practitioners of Chinese medicine must gain a better understanding of this condition and how to best serve their oncology patients, including how the impact of jing can be seen on a cellular level. Insight into cancer and cancer development can be understood by a careful observation of jing, the meeting of jing and shen to create life, and constant changes in the jing as part of growth and development. This lecture will focus on diagnosis and the clinical application of acupuncture to support jing. It will include new insights into the role of marrow, extra meridians, toxins in cancer, and modern treatments such as chemotherapy, as well as discussion of case studies and research.
