Because of the special position of ovaries “deep in the pelvis”, they are not easy to be touched during gynecological examinations, so ovarian tumors with early symptoms are often easily overlooked. Although the early symptoms of ovarian tumor are not obvious, there are still signs. Most of the early ovarian cancer patients have no change in menstruation, but as the cancer tumor increases, the cancer cells will destroy the normal ovarian tissues and cause ovarian dysfunction, resulting in menstruation or amenorrhea. 2. Pain in the lower back and abdomen If the tissues adjacent to the ovaries are infiltrated or adhered by tumor cells, it will easily cause hidden pain or dull pain in the lower back and abdomen. 3.Oedema in the vulva and lower limbs As the ovarian cancer tumor increases, the pelvic veins are compressed, resulting in poor blood flow and obstructing lymphatic flow, resulting in edema in the vulva and lower limbs. 4.Gastrointestinal symptoms If menopausal women often feel bloated and lose appetite, and no gastrointestinal disease is found after gastroenterological examination, ovarian tumor detection can be considered at this time. Because ovarian tumor will cause the surrounding ligaments to be compressed and stretched, coupled with ascites irritation, gastrointestinal symptoms will often appear. 5.Sex hormone disorder Ovarian cancer has complex and variable pathological types. Some tumors that secrete too much estrogen may cause precocious puberty, menstrual disorders or postmenopausal vaginal bleeding; if it is testicular mother cell carcinoma, it will produce too much androgen and show masculine signs. 6.Unexplained wasting As ovarian tumor grows gradually to form ascites, it can mechanically compress the gastrointestinal tract, causing reduced food intake and indigestion. In addition, cancer cells consume a lot of nutrients in human body, which makes patients lose weight, become anemic and weak, and have a pale complexion. What are the factors related to ovarian tumor? 1.Endocrine factors Ovarian cancer mostly occurs in women who have not yet given birth or have not yet had children, and pregnancy seems to have an antagonistic effect on ovarian cancer. Because of the repeated ovarian epithelial lesions caused by cyclic ovulation is related to the etiology of ovarian cancer. In addition, breast cancer and endometrial cancer are mostly complicated by ovarian cancer, and all three diseases are estrogen-dependent. 2.Environmental factors The etiology of ovarian cancer may be related to high cholesterol in the diet. In addition, ionizing radiation, asbestos and talcum powder can affect oocytes and increase the chance of ovarian cancer; smoking and vitamin A, C and E deficiency may also be related to the cause of ovarian cancer. Genetic and family factors About 20-25% of ovarian cancer patients have tumor patients in their immediate family members. This is one of the more common causes of ovarian cancer. When your body (especially the middle-aged and elderly women who have gained weight) suddenly “gets fat”, don’t be careless, maybe gynecological tumor is coming to you quietly at this time. We should pay attention to the maintenance of our ovaries and reproductive system, so that we can overcome the sudden diseases!
