Breast cancer is a malignant tumor that seriously threatens women’s health and life, and its incidence rate is increasing year by year, ranking the first among female malignant tumors. After treatment, the most important thing that every breast cancer patient fears is recurrence and metastasis, which is the main reason and key factor that long-term survival rate has not been significantly improved. So, how to prevent or interrupt recurrence and metastasis? 1.Post-operative radiotherapy and chemotherapy can only remove the tumor, while radiotherapy and chemotherapy can clear the residual cancer cells in one step. Generally, they should be applied reasonably according to the surgery, tumor stage, pathological type, lymph node metastasis and tissue receptor status, etc. Breast cancer is a local reaction of systemic disease. Surgery and radiotherapy mainly solve local problems, while chemotherapy does not distinguish between the enemy and me, which kills cancer cells and at the same time kills normal cells and damages the immune function of the body. As part of the comprehensive treatment of breast cancer, Chinese medicine treatment, combined with surgery, radiotherapy and chemotherapy, can regulate the function of the body as a whole, balance the body’s yin and yang, enhance the body’s constitution, improve the symptoms, promote recovery, create favorable conditions for surgery, radiotherapy and chemotherapy, eliminate their toxic side effects, strengthen the therapeutic effect, improve the immune function of the body, and prevent post-operative cancer. immune function of the body, prevent postoperative spread and metastasis; prolong the survival period and improve the quality of life. Therefore, Chinese medicine must be taken early, one week after surgery. Research shows that the proliferation cycle of breast cancer cells takes a long time, and a cancer cell must undergo 30 times of repeated multiplication and take 2 ∽ 17 years to grow into a lump of 1 cm in diameter. Therefore, the cure medicine for breast cancer can only be confirmed after long-term observation. In the 3 years after surgery, the supporting Chinese medicine and the anti-cancer medicine are given equal importance to remove the residual cancer cells and reduce the chance of recurrence and metastasis; in the 3 years after surgery, the supporting Chinese medicine is the main focus, and the anti-cancer detoxifying medicine is gradually reduced; after 5 years after surgery, the main focus should be to support and strengthen the root and cultivate the vital energy, thus improving the quality of life. The survival period is prolonged. The main drugs used to improve the immune function are Astragalus membranaceus, Radix et Rhizoma prince’s ginseng, Atractylodes macrocephala, Poria, Radix Angelicae Sinensis, Radix Rehmanniae, Fructus Lycii, Fructus Lycii, Dendrobium, Dendrobium, Asparagus, Radix Salviae Sinensis, Rhizoma Polygonati, Spleen, Boneset, Deer Antler, Turtle Board and Turtle Nail. The mushroom, seaweed, whole gourd basket, oyster, coix seeds, etc.; the qi-regulating and blood-activating August zha, Yanhuosuo, Curcuma longa, Shijiazhuang, etc.; the poison fighting with poison, Shengnanxing, snake Liuggu, beehive, centipede, Tianlong, whole scorpion, etc. Generally, 5 years after surgery, you can take Chinese medicine, such as Zhi Ling capsule, Liu Wei Di Huang Wan, Guei Qi punch, etc., to improve the immune function of the body, and regularly go to the hospital for review and follow-up, and cooperate closely with the physician to prevent breast cancer recurrence and metastasis. According to the World Health Organization, “1/3 of cancer can be prevented, 1/3 can be cured and 1/3 can be prolonged”. Breast cancer is a serious disease, but it is not an incurable disease. The patient’s relatives should give the patient the utmost consideration and love, so that the patient can be distracted and tell the fear, bitterness or loneliness that exists in the mind, thus eliminating the psychological fear of cancer, relieving the psychological pressure, maintaining a relaxed, stable, optimistic and cheerful mood, and improving the patient’s confidence and joy of life. This can obviously improve the treatment effect. 5.Rational diet Avoid eating hormone-containing health products and poultry fed with hormones. Avoid eating moldy, pickled, smoked and fried foods, and pay attention to rationalization, diversification and nutrition of diet to nourish the righteousness. Don’t be partial, pay attention to the combination of cereals, fruits, meat and vegetables, eat more vitamin-rich foods, and eat more fresh green vegetables and fruits. Eat more fruits and vegetables with anti-cancer and anti-cancer effects, such as soybeans, carrots, cabbage, mushrooms, cabbage, rape, capers, mustard, dasheen, garlic, shiitake mushrooms, silver fungus, as well as hawthorn, figs, sugar cane, water chestnuts, ling, kiwi, apples, dates, pineapples, mandarin oranges, lilies, etc. In addition, you can eat more sesame seeds, pumpkin seeds, watermelon seeds, peanuts, raisins and other nutritious dried fruit foods and more soy products and yogurt. Research shows that long-term physical exercise, especially aerobic physical exercise, can reduce the risk of breast cancer recurrence and metastasis. Therefore, appropriate physical activities should be encouraged, but only if physical strength allows, so as not to feel fatigue. Such as ballroom dancing and appropriate qigong therapy. 7. Be careful with hormonal drugs Because of the improvement of living standard and people’s demand for quality of life, some people often take estrogen-containing drugs to prevent aging, rub estrogen-containing skin creams or take estrogen drugs during menopause to reduce the symptoms of hormonal withdrawal, which relatively increase the risk of breast cancer recurrence and metastasis. Our principles are: not to use them as much as possible; even if you want to use them, you should choose the smallest dose and the shortest course of treatment (of course, under the condition of ensuring the efficacy); avoid using estrogen-containing contraceptives as much as possible, and use other methods of contraception. 8, develop good habits Do not smoke and stay away from smoking environment; try not to drink alcohol; drink less coffee, tea, chocolate, etc.; keep bowel movements smooth and regular bowel movements. 9.Lose weight Excessive nutrition and weight gain can increase the risk of breast cancer recurrence and metastasis. Therefore, it is necessary to reduce the intake of high-fat, high-calorie and high animal protein foods, such as fatty pork, cream and various kinds of sweet food. After the first treatment of breast cancer (surgery, radiotherapy, chemotherapy, etc.), very few tumor cells still remain, which are the root cause of recurrence and metastasis, and coupled with the low immune function, poor mental and nutritional status, and overwork, the tumor is prone to resurgence. Recurrence of metastasis often occurs within 5 years after treatment, especially within 2-3 years, and can also occur after 5 years, thus regular follow-up is lifelong. The closer the time to the end of the first treatment, the shorter the interval between follow-up visits should be. Usually, the review is done every 3 months for 2 years after surgery. The next 3 years, every 6 months, and then once a year. The review includes treatment local, contralateral breast, bilateral axillary and supraclavicular lymph nodes, lung and abdomen. In addition, routine blood, liver function, immune function, CEA, CA-125, CA-153, chest X-ray, contralateral breast radiograph, ultrasound of liver and pelvis, etc. For patients with possible metastatic cancer, bone, liver, brain and lung scans, etc. should be done.
