The most commonly used screening method for ovarian cancer is the B-ultrasound examination of the adnexa uteri. The B-ultrasound can detect ovarian masses and tumors, and when these are found, the possibility of ovarian cancer should be considered, necessitating further examinations for confirmation. Another method involves the tumor marker CA125, which is relatively sensitive and specific for epithelial ovarian cancer. Therefore, for ovarian cancer screening, we can perform a blood test for CA125 in conjunction with a B-ultrasound of the adnexa uteri.

How is ovarian cancer treated?

Our treatment principle is that once an ovarian tumor is detected, surgical treatment should be performed. First and foremost, we need to confirm the diagnosis. Second, we should clarify the pathological staging of the ovarian cancer to guide the treatment. It's not a single approach; it's a comprehensive treatment plan. For example, if it is early stage and there are no surgical contraindications, we can proceed with surgical treatment. After the surgery, we can provide adjunctive chemotherapy. If surgery is not immediately feasible, we can also provide neoadjuvant therapy to reduce the stage before proceeding with ovarian cancer surgery. Moreover, there is now targeted therapy and immunotherapy for ovarian cancer, so it is a comprehensive treatment plan.

Ovarian Cancer Dietary Precautions

The occurrence of ovarian cancer is not greatly related to dietary habits, so there are no special dietary restrictions or forbidden foods for patients with ovarian cancer. In Western medicine, unlike Traditional Chinese Medicine, which mentions certain "stimulating foods," there are no such prohibitions. Therefore, the diet for patients with ovarian cancer is the same as for anyone else, only requiring a balanced, comprehensive nutrition, and a combination of meat and vegetables. There are no special dietary considerations needed.

What are the symptoms of ovarian cancer?

Some early symptoms of ovarian cancer patients include a lump in the abdomen that can be felt during gynecological examination or by the patients themselves. In advanced ovarian cancer, as the tumor progressively enlarges, there may be symptoms like abdominal pain, bloating, decreased appetite, and weight loss. Moreover, the tumor may compress other organs in the pelvic cavity, causing symptoms such as a feeling of heaviness in the lower abdomen or even constipation. Additionally, many patients with ovarian cancer may develop significant ascites, which can also cause abdominal distension, decreased appetite, and even nausea and vomiting, along with other gastrointestinal symptoms.

How is ovarian cancer diagnosed?

Ovarian cancer is discovered through transvaginal ultrasound of the adnexa uteri revealing ovarian tumors, or through imaging studies such as abdominal CT scans or MRIs showing ovarian tumors, combined with tumor markers, particularly the ovarian epithelial cancer tumor marker CA125, which will be significantly elevated. Generally, with these findings, ovarian cancer can typically be clinically diagnosed. Confirmation, however, requires pathological diagnosis, which involves obtaining a biopsy of the tumor. This can be done through a puncture biopsy or through pathological examination after surgical excision to confirm ovarian cancer. Additionally, some patients with ovarian cancer present with substantial ascites at the time of discovery. If cancer cells are found in the abdominal fluid, combined with a significant increase in CA125 and imaging studies showing ovarian tumors, ovarian cancer can also be diagnosed.

What are the early symptoms of ovarian cancer?

The early symptoms of ovarian cancer are not severe or common clinically. Some patients may experience abdominal distension and pain. Some may have menstrual irregularities, such as prolonged or shortened menstrual cycles, increased menstrual flow, or irregular bleeding outside of menstruation. Additionally, a small number of patients may experience pelvic pain due to local tumor compression caused by ovarian cancer. This pain occasionally radiates to the perineal area and is generally mild, rarely affecting the patient's quality of life. Furthermore, a minor proportion of ovarian cancer patients, particularly those with tumors having endocrine functions, may exhibit symptoms associated with paraneoplastic syndromes.
