Causes of Breast Cancer

Although breast cancer is the most common malignant tumor in women, its incidence rate ranks first both at home and abroad. However, there is no clear reason for this. Epidemiological surveys have found that the occurrence of breast cancer may be related to the following high-risk factors: 1. Early menstruation, late menopause, and long menopause in women; 2. Unmarried, childless, and non-breastfeeding; 3. Family history of breast cancer, that is, history, that is, breast cancer patients in direct relatives; 4. According to the judgment of professional doctors, atypical proliferative breast disease and other precancerous lesions.

Symptoms of breast cancer recurrence after surgery

Breast cancer patients need regular checkups after treatment. Patients in the late clinical stage may relapse and metastasize early, with a peak relapse rate of 2-3 years, especially triple-negative patients, who need to be checked in a timely manner. Common metastatic sites of breast cancer include the liver, lungs, bones, etc. When metastatic lesions are found through liver ultrasound, lung CT, and bone scan imaging, patients generally have no obvious symptoms, and are often manifested as an increase in tumor markers. Symptoms of postoperative recurrence in breast cancer patients include cachexia, cough, hemoptysis, dyspnea, bone pain, etc.

Side effects of long-term breast cancer medication

LuminalA and LuminalB breast cancers require long-term medication after surgery. Treatment drugs include estrogen antagonists and aromatase inhibitors, the former of which is commonly used in clinical practice. According to evidence-based medicine, patients are often encouraged to take medication for ten consecutive years. The side effects are mainly osteoporosis and cardiovascular and cerebrovascular diseases caused by changes in blood viscosity. Patients who take medication for a long time are advised to increase outdoor activities appropriately and take drugs or foods that are conducive to calcium absorption. If the side effects are obvious, they should be controlled in time, but the medication should not be stopped. Please combine the specific medication with clinical practice and follow the doctor's face-to-face guidance.
