Patients suffering from follicular membranous cell tumor may have no obvious discomfort in the early stages of the disease. As the disease progresses, symptoms such as abdominal pain, abdominal masses, and vaginal bleeding may occur. In the early stage of the disease, if the tumor is small, the patient may have no discomfort. When the size of the follicular membranous cell tumor gradually increases, the estrogen level in the patient’s body will gradually increase, causing the patient to experience symptoms such as menstrual cycle disorders and irregular vaginal bleeding. As the tumor increases in size, the patient may develop abdominal masses, which can be palpated on palpation, usually with smooth surface and no pressure pain. At this time, the patient’s abdomen may also be accompanied by a sinking, drawing pain. If follicular membranous cell tumor has malignant transformation, it means ovarian cancer, and the patient may have systemic manifestations such as body weakness, fever, loss of appetite and so on. Patients with follicular membranous cell tumor have different degrees of illness, and the corresponding clinical manifestations are also different. Once diagnosed with follicular membranous cell tumor, it is recommended to seek medical treatment in time to avoid delaying the condition.
