Breast cancer diagnosis: Breast cancer is the most common malignant tumor in women. the incidence rate of women over 30 years old is increasing year by year, and the peak incidence is between 45 and 55 years old. With early diagnosis and proper treatment, the survival rate of breast cancer is almost 100%, so for accurate early diagnosis, please receive regular professional checkups. Breast cancer treatment: The current treatment is based on surgery, radiotherapy, endocrine therapy and Chinese medicine treatment. Advantages of Chinese medicine in treating breast cancer: According to Chinese medicine, “where evil comes from, its qi must be deficient”, the decisive factor of breast cancer recurrence and metastasis is the deficiency of positive qi. Although the residual cancer cells are eliminated as much as possible by surgery, radiotherapy and chemotherapy, eventually there are still a small portion of cancer cells that cannot be completely eliminated by the above-mentioned comprehensive therapies, and the residual cancer cells can grow again under certain circumstances, and recurrence and metastasis occur. Moreover, after the comprehensive treatment, most of the patients have a deficiency of positive energy and an imbalance of qi, blood, yin and yang. Chinese medicine treatment for breast cancer is based on the treatment principle of supporting the positive and eliminating the evil, balancing the qi, blood, yin and yang in the body by improving the patient’s own immune function. ”Breast Cancer Treatment Formula”: Our department adopts Professor Lu Deming’s experienced formula “Breast Cancer Postoperative Formula” to treat postoperative patients with breast cancer. This formula is based on the principle of strengthening the spleen and the kidney, and it can help to support the righteousness by tonifying the innate and the postnatal; it is combined with the herbal medicine of invigorating blood and detoxifying to dispel the evil. Through several clinical trials and animal experiments, we found that “Postoperative Breast Cancer Formula” can prolong the disease-free survival of early-stage breast cancer, improve clinical symptoms and quality of life of breast cancer patients during and after chemotherapy, improve the side effects of endocrine therapy for breast cancer, and enhance the immune function of breast cancer patients.
