Ovarian cancer

1380604767

The ovary in the woman’s pelvis is as large as the size of the thumb.
There are one on each side of the uterus, floating in the pelvis supported by the ligament of the uterine body part. A wide variety of tumors develop in those ovaries.
Ovarian tumor is classified into 3 types, depending on where the tumor is formed:
Ⅰ. Superficial epithelial / interstitial tumor
Ⅱ. interstitial interstitial tumor
Ⅲ. germ cell tumor.

Furthermore, the tumor is divided into three types: (1) benign, (2) boundary malignant (intermediate between benign and malignant), (3) malignant.

The most common occurrence is surface epithelial / interstitial tumor, and approximately 90% of malignant ovarian tumors are of this type. Speaking of “ovarian cancer”, it generally refers to this malignant tumor. The complaint of "getting hungry“ and “gaining weights" are seen in patients, but it is difficult to detect at an early stage because there are few subjective symptoms. On the other hand, ovarian cancer is also classified by “tissue type” (type of cancer cell tissue). The majority is a type called adenocarcinoma, which is divided into four types: ①serous gonad cancer, ②endometrial adenocarcinoma, ③mucinous adenocarcinoma, ④clear cell adenocarcinoma.

Even if it says ovarian cancer, the way in which anticancer drugs are effective depends on the tissue type. Therefore, it is important to know what kind of tissue your cancer is in order to proceed with treatment.

Symptoms of ovarian cancer

The ovaries are called "organs of silence", and even if they are malignant or benign, the symptoms do not appear at all in the degree that the ovaries are somewhat swollen. When the tumor becomes extremely large, it may be noticed by a stomach feeling of pressure or the like, but there are many cases that happen to be discovered by chance at the medical checkup or examination by other symptoms. When it become the size exceeding the height of navel, it seems that you may be aware of the symptoms such as “Stomach feels bloated" or "Waist is tight”. This is because the lower abdomen is pressed indeed. There are some patients who did not notice anything until the examination even if there was a tumor of about 20 cm in size. As it progresses, symptoms such as lump in the lower abdomen, pain in the lower abdomen, frequent urination, dysuria, constipation, low back pain, and weight loss are seen. In addition, as it metastasize, pleural effusion, ascites, dyspnea, swollen lymph node swelling are seen.

Ovarian cancer examination

· Abdominal palpation, internal examination
· Ultrasonic examination
· Blood test (tumor marker)
· CT, MRI
· PET-CT test

Recommendation of medical examination

Taking CT or MRI once a year at medical checkups is quite inefficient and it will be a waste of medical expenses. If you receive ultrasonography from the vagina at the same time when undergoing uterine cancer examination, the swelling of the ovaryes will be checked. By doing so, it is possible to check simultaneously whether there is uterine fibroids or endometriosis, whether the endometrium is too thick or not, and so on.

Ultrasound examination to be performed during regular uterine cancer screening etc. will be self-expensive, however, we recommend that you get it at the same time as other screening.
