Types and symptoms of uterine cancer


Types and symptoms of uterine cancer.   The histological types of cervical cancer are roughly divided into adenocarcinoma. Squamous carcinoma accounts for about 70% of the total, and adenocarcinoma accounts for about 20%.

Types and symptoms of uterine cancer

 


About the uterus

The uterus is an organ in the female pelvis, and the size of an adult woman is about the size of an egg. The uterus is divided into the lower cylindrical cervix and the upper bagged uterus. The underside of the neck of the uterus is connected to the vagina, and fallopian tubes emerge from the left and right sides of the uterus. In addition, there are ovaries on both sides of the uterus. The basal ligament is one of the tissues around the cervix (parauterine tissue) that supports the uterus.

The uterus is the organ that nurtures the fetus during pregnancy. It is formed by muscle, and the inner side is covered by the mucosa of the endometrium. When the endometrium is affected by estrogen (follicle hormone) secreted by the ovaries. Prepare for the implanted fertilized egg, proliferate and thicken, if there is no pregnancy, it will peel off, this is called menstruation. This cycle until amenorrhea is repeated every 4 weeks.


Uterine body cancer (endometrial cancer)

Uterine cancer is divided into “uterine corpus cancer” that occurs in the uterus and “cervix cancer” that occurs in the neck of the uterus.

Uterine body cancer is also called endometrial cancer because it originates from the endometrium.

In addition, there are some tumors that grow from the muscle layer of the uterus. The benign ones are called uterine fibroids, and the malignant ones are called uterine sarcomas (carcinosarcoma or leiomyosarcoma, etc.). Uterine sarcoma is very rare compared with uterine body cancer. It is a malignant tumor, but it is different from uterine body cancer.

Symptom

The most common subjective symptom of uterine body cancer is bleeding. If there is bleeding during non-menstrual periods or after menopause, please pay more attention. The degree of bleeding is bloody discharge, or only brown liquid. Other symptoms include pain or difficulty urinating during urination, pain during sexual intercourse, and pain in the lower abdomen. If you progress, you will feel bloating.

If the above symptoms occur, please go to the gynecology department as soon as possible for early detection.

Classification of histological type (classified according to the status of tumor tissue)

Uterine body cancer is classified into histological types such as endometrial cancer, serous cancer, and clear cell carcinoma according to the tissue state of the cancer. The most common of these is endometrial cancer. Serous carcinoma and clear cell carcinoma are considered to be highly malignant.

Related diseases

Endometrial hyperplasia is one of the uterine diseases, and endometrial hyperplasia is a state of abnormal endometrial proliferation. When the proliferating cells are abnormal, it is called endometrial dysplasia. After the onset of endometrial dysplasia, cancer of the uterus is likely to occur, and it should be clear that it has become cancer.

Number of patients (cancer statistics)

Approximately 16,000 people are diagnosed with cancer of the uterus in one year in Japan. The number of people diagnosed with uterine body cancer began to increase from around 40 years old, and reached a peak in the 50s to 60s.

Prevention and screening

1) Prevention

According to the research results of Japanese people, quitting smoking, drinking moderately, eating a balanced diet, physical activity, proper body shape and infection prevention can effectively prevent cancer.

2) Check

The purpose of cancer screening is to reduce cancer mortality through early detection of cancer and appropriate treatment.

If you have any symptoms you care about, it is recommended to go to the gynecology department as soon as possible. If you voluntarily accept medical examinations such as human examinations, please understand the advantages and disadvantages of medical examinations.

 

 

Cervical cancer

Uterine cancer is divided into “uterine corpus cancer” that occurs in the uterus and “cervix cancer” that occurs in the cervix. Cervical cancer occurs in the cervix at the entrance of the uterus. It usually occurs near the entrance of the uterus, and it is easy to observe and check in the gynecological examination, and is easy to be found. In addition, if early detection is easier to treat and has a good prognosis, but treatment is more difficult after progression, early detection is very important.

After cervical cancer progresses, it will spread to the lymph nodes in the pelvis, spread along the main ligament supporting the uterus, and metastasize through blood vessels and lymphatic vessels (lungs, etc.)

symptom

Cervical cancer does not change from a normal state to cancer immediately. Dysplasia is a pre-cancer state, which becomes cancer after several years of development. During the period of dysplasia, there are no symptoms, no discharge, bleeding, and pain.

After cervical cancer progresses, it may bleed during non-menstrual periods or during sexual intercourse, and there will be increased dark brown or pus-like secretions, and more watery or rice-like fluid will be discharged. After further progress, lower abdomen and low back pain may occur. If you have any symptoms of worry, please do not hesitate to go to the gynecology department as soon as possible.

Classification of histological type (classified according to the status of tumor tissue)

The histological types of cervical cancer are roughly divided into adenocarcinoma. Squamous carcinoma accounts for about 70% of the total, and adenocarcinoma accounts for about 20%. Both squamous epithelial carcinoma and adenocarcinoma have a precancerous state. Among them, dysplasia and intraepithelial carcinoma (cervical intraepithelial neoplasm CIN) called precancerous lesions must be treated.
