There are more than 1.2 million new cases of breast cancer worldwide each year, and more than 500,000 patients die from breast cancer each year. The incidence rate of breast cancer in China is lower than that in Europe and the United States, but it is increasing at a rate of 2% to 3% per year, and the peak age of incidence is 40 to 50 years old, about 10 years earlier than that in Europe and the United States. The efficacy and quality of survival of breast cancer mainly depends on the clinical stage of breast cancer at the time of consultation, i.e., the size of breast cancer, whether there is infiltration and metastasis. Therefore, early diagnosis and early treatment of breast cancer are especially important. Currently, the examination of breast disease mainly relies on the clinician’s consultation, infrared examination, color ultrasound and mammography, etc. The accuracy of color ultrasound and mammography is about 90%, while the accuracy of infrared examination is lower. CT and MRI are also good examinations, but they are more expensive and are not used as a routine technique for breast diseases. The most common pathological type of breast cancer is invasive ductal carcinoma, most of which has a more characteristic malignant presentation and has a higher diagnostic accuracy than other pathological types. Other pathological types of breast malignant tumors, such as mucinous carcinoma, medullary carcinoma, malignant lobular tumor, sarcoma, etc., are easily misdiagnosed as benign tumors, and are usually only taken seriously when the tumor is found to be growing during the review. If a lump is found to be enlarged, an accurate diagnosis can be made by biopsy or surgical removal of the lump. The majority of patients with breast pain have no clear masses on ultrasound and radiography, and are usually clinically diagnosed with “mastopexy” the above examination may be described as not seeing an exact mass, and whether these patients with “mastopexy” are medicated depends mainly on the severity of the pain The degree of pain, firmness and uniformity of palpation. The majority of patients with no lumps of breast enlargement only need to be aware of their health care, and they can have a follow-up ultrasound or mammogram once or twice a year. For patients with lumps, if they are cysts, they are usually benign. If it is a solid mass, it requires ultrasound or radiologist as well as clinician to determine the benign and malignant nature of the mass. For solid masses judged to be benign, regular follow-up is required, and for those judged to be malignant, prompt treatment is needed. The most effective treatment is surgical excision, whether breast-conserving surgery is possible, whether chemotherapy or radiotherapy is needed, and whether chemotherapy should be used before or after surgery, need to be guided by a breast specialist. Patients with breast cancer must face the disease bravely, treat it actively and live optimistically. Breast cancer patients can also live a wonderful life.
