Breast cancer is now increasingly becoming one of the most prevalent tumors in urban women. Early detection and early treatment can lead to longer survival time and better quality of life for most early stage patients. Benefits of early detection and early treatment: If the breast is large, you can choose breast-conserving surgery with the cooperation of plastic and cosmetic surgeons, the appearance is basically symmetrical with the opposite breast, which does not affect the quality of life and reduces the pressure on yourself and your spouse. If the breasts are smaller one can also choose simple mastectomy without removing the pectoralis major muscle. After surgery, you can have breast implants in plastic surgery, which can have a better feel and appearance and greatly improve your quality of life. After surgery, you can choose radiotherapy and endocrine therapy according to your condition. What are the methods of early detection and diagnosis: 3-10 days after each menstruation is the best time for self-examination of the breast, you can lie in a flat position and touch the various parts of the breast with both hands, do not grasp and pinch. If a swelling is found then go to the hospital for a physical examination. You can also visit the hospital for regular checkups.
