Carcinoembryonic antigen is primarily found in malignant tumors of the digestive tract, such as colorectal cancer and gastric cancer, where it tends to be significantly elevated. It is also elevated in patients with lung adenocarcinoma. In cases of ovarian cancer, carcinoembryonic antigen may be elevated, but the most primary, sensitive, and specific tumor marker is CA125, which usually shows a significant increase. However, CA125 is specifically elevated in the pathological type of epithelial ovarian cancer.

Ovarian cancer requires the following examinations:

The examination for ovarian cancer begins with an abdominal ultrasound, which can clarify the tumor's size, shape, cystic or solid nature, location, and its relationship with neighboring organs. If necessary, CT scans and MRI can be conducted for a clearer view. Next are tumor markers, which are essential in the diagnosis of ovarian cancer. Additionally, CT scans of the lungs and head, or MRI, and a complete blood count of bone can help rule out distant metastasis. The most critical part is the pathological diagnosis, as the definitive diagnosis of tumors primarily relies on pathology. We can obtain a clear pathological diagnosis through laparoscopy or exploratory laparotomy.

Ovarian cancer pain symptoms

In the early stages of ovarian cancer, the symptoms can be quite hidden, and the patient may not feel any discomfort at all. However, as the tumor grows and ascites develops, the patient typically may experience abdominal bloating, or a palpable mass may be felt in the pelvic or lower abdominal area. At this point, symptoms such as pain in the lower abdomen may occur, especially when there is a substantial amount of ascites, leading to clinical symptoms like abdominal bloating and pain. In even more advanced stages of ovarian cancer, the tumor may invade surrounding pelvic organs, potentially causing partial intestinal obstruction or symptoms of pelvic compression. With conditions like intestinal obstruction, there will be significant abdominal pain, possibly accompanied by vomiting, especially after eating, which can exacerbate the symptoms.

What should be noted about having intercourse after ovarian cancer surgery?

Patients with ovarian cancer can have sexual intercourse after radical surgery or palliative surgery, but there are several precautions to consider: Firstly, it is not advisable to have sexual intercourse too soon after surgery, as early intercourse may lead to poor healing of the surgical site, or cause infections, which are detrimental to the patient's recovery. It is generally recommended to schedule sexual intercourse one or two months after ovarian cancer surgery, and some patients are advised to wait three months. After three months, most patients' physical conditions improve and the incisions heal. In such cases, the likelihood of infection from intercourse is low. Moreover, the frequency of sexual intercourse should not be too frequent or excessive, as it may impact the patient's physical strength or lead to concurrent infections. Furthermore, patients should practice contraception during intercourse after surgery, as pregnancy is not advisable for patients who have undergone radical or palliative surgery for ovarian cancer, since pregnancy can exacerbate the development of the disease.

How is ovarian cancer screened?

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.

Symptoms of ovarian cancer brain metastasis

Patients with ovarian cancer experiencing brain metastases are relatively uncommon in clinical settings. The primary symptom of brain metastasis is intracranial hypertension, which includes severe headaches, dizziness, nausea, and vomiting, including projectile vomiting during meals — all symptoms of increased intracranial pressure. Additionally, if there is significant brain swelling, the patient may experience weakness in the limbs on the opposite side of the body, similar to symptoms of paralysis seen in stroke patients. Furthermore, if the brain metastasis leads to the formation of a brain herniation, the patient may experience symptoms such as coma.
