When breast cancer is very early, it is clinically asymptomatic and lumpless, and is very difficult to detect unless special screening methods are applied. In order to detect breast cancer early, the best way is for women to learn to examine their own breasts regularly, so that the tumor can be detected before it grows. If you find nipple discharge or eczema-like changes in the breast or a small nodule during self-examination, don’t let it go, because most of these abnormalities are the first signs of breast cancer. Nipple discharge or eczema-like changes are easy to detect due to water stains in underwear, while small nodules are painless and easy to ignore if you don’t pay attention to them. Whenever this happens, you should immediately go to the hospital for further examination. Patients and medical personnel should pay great attention (not nervousness) to any small abnormalities in the breast, such as mild depression of the breast skin (medically called “dimples”), or thickening of the skin of the breast and enlargement of pores (medically called “cellulite”). “These abnormal changes are also often characteristic of breast cancer. Sometimes it may not be reliable to rely on these conditions alone to detect early clinical cases, and we should analyze them comprehensively with the age of the patient. Those aged between 35 and 55 are the high incidence stage of female breast cancer. In addition to clinical confirmation of benign tumors, various methods of detecting breast cancer such as local needle aspiration of lumps, cytological examination, excisional biopsy and thrift are often required for suspected cancerous tumors to make a definite diagnosis and avoid the occurrence of missed diagnosis and misdiagnosis. Therefore, we hope that every woman can insist on self-examining her breast once a quarter, so that most cancers can be detected at an early stage. The cure rate of early breast cancer can reach 80-90%, which can greatly improve the efficacy of breast cancer. According to our experience, more than 95% of breast cancers can be diagnosed through a combination of multiple tests and clinical examination.
