Moxibustion can be applied to treat advanced rectal cancer, which can relieve pain and poor appetite and other symptoms, but simply treating advanced rectal cancer symptomatically with moxibustion may only play a certain degree of adjuvant treatment, and may not completely alleviate metastasis and recurrence caused by advanced rectal cancer from the root. Once the symptoms of advanced rectal cancer appear, besides symptomatic treatment, nutritional support therapy can be applied, including subclavian vein puncture to give a certain amount of nutritional fluid, which can maintain the physiological needs of energy of patients with advanced rectal cancer, and also maintain life through intestinal and parenteral nutrition. Allopathic treatment programs such as traditional Chinese medicine, microwave physical therapy and western medicine can be applied to improve the quality of survival and reduce pain and suffering in advanced rectal cancer.
