Ovarian cysts are a relatively common disease of the ovaries. The ovary is a smaller organ in the body and is a frequent site of tumors. Long-term dietary structure, poor living habits, and excessive psychological stress may lead to ovarian pathology. Ovarian cysts can be closely observed if they are less than 5cm. If it is larger than 5cm, surgery should be considered. Nowadays, surgical treatment can be open surgery or minimally invasive laparoscopic surgery, both of which are not too invasive. Then consider doing pathological section to see the nature of the cyst and exclude malignant tumor, which is allowed to grow in an acidic environment. So keeping the body weakly alkaline can inhibit tumors. Usually eat more weak alkaline food, seafood, fresh vegetables and fruits, develop good living habits and keep a good state of mind.
