The regular holiday in chemotherapy has a certain impact. But overall, this problem requires specific analysis of individual circumstances. First of all, we must understand that whether it is weekly chemotherapy or a two-week, three-week cycle of chemotherapy, the rhythm of these chemotherapy is the most important.

Less than last resort, such as white blood cells are too low, fever infection, etc., will only delay chemotherapy. Therefore, the rhythm of chemotherapy is very important, and it is the most effective plan obtained after decades of clinical research. Therefore, the problem of menstruation is easy to understand. Unless the amount of menstruation is usually large, large or serious to anemia, these people, it is best to avoid chemotherapy, because menstrual blood loss is very bad, the constitution is very poor, and then chemotherapy, people will be unable to eat, will cause anemia to increase, physical fitness The decline, secondary infections, etc., have serious consequences for subsequent chemotherapy. If the menstrual flow is not very large and the physical decline is not very severe, it is better to schedule chemotherapy. Therefore, it must be individualized.

For a more intuitive and simple understanding, you can simply refer to the following situations:

　　1, no effect: Menstrual disorders, no amenorrhea;

　　2. Post-menopausal recovery: menopause resumes after a short period of amenorrhea for more than 3 months;

　　3. Amenorrhea does not recover: the amenorrhea has not recovered for more than 1 year. With the growth of female breast cancer patients, the proportion of amenorrhea increased significantly.

Chemotherapy drugs have an effect on ovarian function. Many patients will have menstrual disorders during chemotherapy, and they will stop temporarily or permanently. Generally, after the end of chemotherapy, some patients can gradually resume menstruation, and some patients may no longer recover from menopause, and the menopause will arrive earlier.
