Headache before menstruation is not directly related to whether you have cancer, don’t worry. Headache before menstruation is most likely to be menstrual headache, which is a common disease during women’s menstruation and can be regulated by oral Chinese medicine. The etiology of menstrual headache in Chinese medicine is mainly due to the weakness of qi and blood, the weakness of kidney yin and hyperactivity of liver yang caused by housework, stagnation of silt and blood, and internal obstruction of phlegm and dampness, etc. Therefore, it can be regulated by replenishing qi and nourishing blood, nourishing the kidneys and submerging the yang, relieving the wind and relieving the pain, activating blood circulation to remove blood stasis, and drying the dampness and removing the phlegm, and the effect is generally satisfactory. While many gynecological cancers do not have obvious symptoms, some gynecological cancers, such as endometrial cancer, may be caused by irregular menstruation and thick endometrium, and lesions in the endometrium are found only after diagnostic scraping; for example, cervical cancer, some of which are found only when routine cervical cancer screening is performed, and some ovarian tumors may be caused by physical examination finding lumps, abnormally elevated tumor markers, and postoperative pathology suggestive of cancer, and the majority of these gynecological cancers do not have symptoms of premenstrual headache. Most of these gynecological cancers do not have the symptom of premenstrual headache. In conclusion, headache before menstruation is not a precursor of cancer, because if headache is caused by cancer, the onset of headache and menstruation are not necessarily cyclical changes, and you may usually have headache symptoms, not every time before menstruation, don’t worry about the onset of headache.
