“Routine self-examination of the body every month is a good basis for the prevention of any disease.” Now the following self-examination methods are introduced for women: 1. Observe the amount of monthly bleeding. Any change in the amount of bleeding that accompanies menstruation is generally cause for alarm. 2, observe the white belt. Normal leucorrhea is a small amount of slightly sticky white secretions, along with the menstrual cycle, its thinness and volume will be some slight changes, such as a significant increase, then need to pay attention to. 3, timely investigation of the source of pain. Frequent pain in the lower abdomen, lower back or sacrococcygeal area, or severe menstrual cramps need to be noted. It may be that the pelvic nerve is compressed by tumor, or various symptoms trigger irregular contractions, and severe tumor compresses the cervix and hinders blood flow, which will cause severe menstrual cramps. 4. Be alert to the difficulty of urination and defecation caused by pressure. If lesions such as fibroids occur in the uterus, they may press on your bladder, rectum and ureter, causing difficulty in urination, defecation and back pain. 5. Self-touch. Lie flat on an empty stomach, bend your knees slightly, relax your abdomen and feel your lower abdomen, from light to heavy, if there is a large lump can be found.
