Ultrasound or CT scans detecting ovarian masses, in combination with biopsy or cytological examination that identify cancer cells, can diagnose ovarian cancer. A common method of biopsy includes ultrasound-guided procedures or transvaginal cul-de-sac puncture biopsy of ovarian masses, enabling clear pathological confirmation. Additionally, exploratory laparotomy or early radical surgery for ovarian cancer patients can yield a postoperative pathological diagnosis of ovarian cancer. Moreover, the presence of ascites is a common symptom in ovarian cancer patients; finding cancer cells, especially adenocarcinoma, in ascites, coupled with significantly elevated tumor marker CA125, or ultrasound or CT imagery revealing ovarian masses, can also diagnose ovarian cancer.

Early Symptoms of Ovarian Cancer

Patients with ovarian cancer may have relatively hidden clinical symptoms in the early stages, possibly without any specific discomfort, or just mild lower abdominal bloating or pain. Symptoms tend to become more apparent only when the tumor progressively enlarges or when ascites occur, such as increased abdominal bloating and pain. Furthermore, during a physical examination, a solid or cystic-solid mass can be palpated in the pelvic area. Ascites can also lead to clinical symptoms such as nausea and vomiting. In the late stages, partial intestinal obstruction or symptoms related to pelvic compression may appear.

early symptoms of ovarian cancer

The early symptoms of ovarian cancer in patients are often not very obvious, so they are not easily noticed. The more common symptom is an abdominal mass, meaning you can feel a lump in the abdomen. In its early stages, the abdominal mass is not large and is not easily detectable. Most patients only discover it during gynecological examinations. As the disease progresses, the mass grows larger and the abdomen visibly expands, leading to symptoms like abdominal pain, bloating, or lower abdominal discomfort. Another symptom is ascites, which is a more common sign in patients with advanced ovarian cancer.

ovarian cancer specific drug

Ovarian cancer does not have any specific cure-all treatment. Most ovarian cancers are epithelial ovarian cancers, and there is also ovarian cancer resulting from malignant germ cells, which is a rarer pathology type. For epithelial ovarian cancer, treatment methods include surgery, radiation therapy, chemotherapy, and some targeted therapies, mainly using Bevacizumab, which is a monoclonal antibody that inhibits angiogenesis, and is usually used in combination with chemotherapy drugs. For patients with advanced ovarian cancer, those who are resistant to chemotherapy, or those in poor general health unable to endure chemotherapy, palliative treatments like hormone treatment using progestogens are an option, along with immune therapy being available nowadays. Surgery is primarily for early-stage ovarian cancer patients, where curative surgical resection is possible, or for debulking surgery in patients with advanced ovarian cancer. Chemotherapy is frequently used as it is relatively effective for epithelial ovarian cancer, a type of cancer that is somewhat sensitive to such treatments. The drugs used mainly include taxane combined with platinum-based chemotherapy. For intravenous administration or intraperitoneal delivery—for the latter, mainly for ovarian cancers complicated by extensive ascites—, positioning an abdominal drainage tube and then infusing platinum-based chemotherapy drugs into the abdominal cavity are utilized.

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.

Does ovarian cancer cause abdominal pain every day?

Patients with ovarian cancer often experience abdominal pain as a common symptom. This is because ovarian cancer can widely implant itself within the pelvic and abdominal cavity, or directly invade the uterus, fallopian tubes, and other tissues and organs within the pelvis, resulting in symptoms of abdominal pain. However, not every patient with ovarian cancer will necessarily exhibit abdominal pain as a clinical symptom, nor is it the case that abdominal pain will occur every day. For instance, some patients with early-stage ovarian cancer may have more concealed clinical presentations and may not experience any specific discomfort. They might discover the disease through physical examinations, gynecological exams, or through ultrasound scans of the uterine adnexa conducted during physical check-ups.
