The examination of cyst gene is mostly for the need of eugenics and childbearing. Especially for women with familial polycystic kidney or polycystic liver, it is recommended to check the cyst gene in a regular hospital. If problems are found, they should be treated in time. Remember not to blindly conceive, do a good job in preventing this disease, and also do a good job in eugenics. Ordinary cyst patients do not need to worry too much, nor do they need to do gene testing. Because most cysts are benign diseases, patients generally do not have any discomfort. If they are found to be benign diseases, they can not be treated specially, as long as they are followed up. However, when the cyst is large or complicated with infection and cannot be excluded as malignant, surgery is required. If it is indicated by postoperative pathology that it is malignant, it needs to go to the oncology department for radiotherapy and chemotherapy. Therefore, patients with cysts should go to a regular hospital to see whether gene testing or other examinations and tests are needed.
