Ovarian teratomas can be safely consumed with red dates if there is no allergy to the food ingredient; red dates can help nourish the body. Ovarian teratoma is a type of germ cell tumor, which can be divided into mature and immature ovarian teratomas. The mature ovarian teratoma, also known as dermoid cyst, is a benign tumor. The cyst is multi-chambered and may be filled with sebum and hair; sometimes teeth and bones may also be present. Immature teratomas are malignant tumors, most commonly found in females aged 11 to 19. Once an ovarian teratoma occurs, it is necessary to visit a hospital for an examination promptly. If required, a CA125 test may be combined with other diagnostic tests. Depending on the results, timely surgical treatment is necessary.
