1. Can early stage breast cancer be cured? Whether it can be cured or not is the main concern of breast cancer patients. In reality, our doctors are also considering this question. In the very early days, doctors thought that some methods could cure the cancer, so many surgical methods were called radical surgery. But now we think it is not accurate to evaluate the treatment effect by radical cure or not, we prefer to use survival rate to evaluate the effect. 2.What is the survival rate of early breast cancer? There are some foreign statistical tools that can calculate the 10-year survival probability of patients based on the size of their breast cancer, lymph node metastasis and staging. After calculation, most of the stage 0~1 breast cancers, meaning those with in situ cancer or lump less than 2cm without lymph node metastasis, have a 10-year survival rate of over 90%. In other words, less than 10% of patients will die, including deaths caused by diabetes, high blood pressure and even car accidents and suicides, but very few people die from breast cancer. For those with stage 2 or higher breast cancer, including breast cancer with lumps larger than 2cm or lymph node metastasis, the 10-year survival rate is about 80%, and the number of deaths due to breast cancer has increased. stage 3 breast cancer is considered locally advanced breast cancer, and stage 4 breast cancer represents breast cancer with organ metastasis, and its survival rate is lower and the treatment plan is more complicated. 3.Do I need chemotherapy for early stage breast cancer? The purpose of applying chemotherapy is to kill the tumor cells in the areas that can be reached by blood through the toxic effect of chemotherapy drugs and prevent the tumor cells in these areas from growing into new tumors. Clinically, the decision of whether chemotherapy is needed or not is mainly based on the stage of the tumor. The earlier the cancer is, the less chemotherapy is needed because it has less chance of bloodstream metastasis. It is clear that in situ cancer definitely does not require chemotherapy. Of course, whether chemotherapy is needed for early-stage breast cancer also needs to be combined with other high-risk factors, such as age, the younger the patient, the more chemotherapy is needed, such as staging, the more malignant the type is, the more chemotherapy is needed.
