Stage Ia ovarian cancer belongs to the early stage of ovarian cancer, and timely surgical treatment will give patients a good prognosis. Ovarian cancer stage Ia is ovarian cancer that has just appeared, the tumor is confined to the ovary and has not metastasized, that is, it has not spread beyond the ovary. Active surgical treatment has a chance to stop its development and minimize the harm to the body. Patients with stage Ia ovarian cancer who are relatively young and have not had children can also undergo surgery to preserve their fertility and have a chance to have children after surgery. Most patients with stage Ia ovarian cancer are found to have abnormal enlargement of one ovary during physical examination, and often have no clinical symptoms. After ovarian cancer surgery, pay attention to regular review, usually once every one year or three months after surgery, once every 4-6 months after two years, and once a year after five years. In life, we should pay attention to rest, reasonable nutrition, avoid fried and spicy stimulating food, and strengthen physical exercise to enhance physical fitness.
