Ovarian cancer is one of the common malignant diseases of female reproductive system, and the symptoms before death may include the following: 1. Excessive thinness and depression, because patients with advanced ovarian cancer have poor mental status and extremely weak immunity, resulting in limited intake of nutrients; on the other hand, cancer cells are very dominant and will draw nutrients from body fat and protein, resulting in patients with advanced cancer being too thin. 2. Most of the ovarian cancer cells will spread and metastasize in the late stage of ovarian cancer, and the cancerous ascites will keep leaking out, resulting in the patient’s abdomen enlarging and even difficult to breathe on their own. At the same time, difficulty in breathing on one’s own will also affect sleep.3. Poor appetite, not only patients with advanced ovarian cancer or other cancerous tumors will have poor appetite, even unwilling to eat or drink. Because of the anatomical structure of ovaries and the lack of obvious discomfort in early stage lesions, early stage lesions are difficult to detect. Therefore, women are strongly urged to take care of their ovaries.
