How to screen for uterine and ovarian cancer in women

Uterine and ovarian cancer is a common disease among female friends. Symptoms include abdominal distension, back pain, distending pain or discomfort, increased abdominal circumference, constipation, fatigue, frequent or urgent urination, inability to eat normally, and unexplained weight loss. So how should women go to the hospital for screening for uterine and ovarian cancer? Let's introduce it to you below.

1. Colposcopy: With the assistance of colposcopy, the diagnostic accuracy of early cervical cancer can reach about 98%. Colposcopy cannot replace scraping cytology and biopsy, nor can it detect lesions in the cervical canal, but it can assist in selecting the biopsy site for cervical biopsy.
2. Biopsy of the cervix and endocervical canal: If the cervical biopsy is negative, four-point biopsies should be taken at 6, 9, 12 and 3 o'clock at the junction of the cervical squamous column, or multiple tissues should be taken for section examination in the unstained area of ​​the iodine test and the suspected cancerous site, or the endocervical canal should be scraped with a small scraper and the scraped material should be sent for pathological examination.
3. Iodine test: Normal cervical or vaginal squamous epithelium contains abundant glycogen, which can be dyed brown by iodine solution, while the columnar epithelium of the cervical canal, cervical erosion and abnormal squamous epithelium have no glycogen, so they are not colored. In clinical practice, after exposing the cervix with a vaginal speculum, wipe off the surface mucus, and smear the cervix and fornix with iodine solution. If an abnormal iodine-negative area is found, a biopsy can be taken from this area for pathological examination.
4. Cervical smear cytology examination: This is the main method for detecting cervical precancerous lesions and early cervical cancer, but attention should be paid to the correct sampling site and careful microscopic examination. It should also be combined with clinical conditions and regular examinations.
