A positive stage 1 breast cancer indicates breast cancer, the cause of which is not yet known but may be related to heredity, exposure to radiation, etc. Breast cancer belongs to a kind of malignant tumor, the cause of which is not yet completely clear. However, it is clinically found that 10% to 15% of breast cancer patients have a family history of the disease, so it is easy to increase the chances of breast cancer if the immediate family members have a history of breast cancer. At the same time, those who receive long-term radiation treatment or examination of the chest may increase the chance of breast cancer due to the gene mutation prompted by radiation. In addition to the above factors, endocrine disorders, over-nutrition, obesity, high-fat diet and other factors may also increase the risk of breast cancer, which need to be emphasized. Early breast cancer symptoms are usually not obvious, but with the discovery of the disease, patients will experience breast pain, nipple discharge, dimple sign, orange peel sign, painless lumps and other symptoms, which seriously affect the quality of life and health. It is recommended that patients with stage 1 positive breast cancer undergo further detailed examination in order to clarify the nature of the disease and the severity of the disease. Patients are advised to adjust their mindset and actively cooperate with doctors for treatment.
