Cervical cancer is the one most women worry a lot because it threatens female’s health and life. Good cervical cancer screening and diagnosis are respectively helpful for cervical cancer prevention and cervical cancer treatment effect. The following methods are cervical cancer diagnosis methods introduced by experts of Modern Cancer Hospital Guangzhou.
Cervical Scraping Smear Cytological Examination
Cervical scraping smear cytological examination is the main approach for detecting precancerous lesion of cervical cancer and early cervical cancer. Be sure to draw the tissue of the wanted spot and careful microscopic examination for there might be 5-10% false negative rate, therefore, clinical situation shall be combined to conduct examination periodically. This is what we can apply as screening.
Normal squamous epithelium of cervix or vagina is rich in amylon and can be dyed into brown by iodine solution, while columnar epithelium of cervical canal, cervical erosion and abnormal squamous epithelium area (including squamous metaplasia, atypical hyperplasia, cancer in situ or infiltrating carcinoma area) are free of amylon, so they cannot be dyed. In clinical, vaginoscope is applied to expose cervix, and then superficial mucago shall be wiped out, after that smear the cervix and fomix with iodine solution, if there is any abnormal iodine negative area, then biopsy of such area shall be passed for pathology check.
Biopsy of Cervix and Cervical Canals
Perform smearing on these examination of III-IV or above of cervical scraping smear cytological examination, if the biopsy of cervix is negative, then the biopsy for 4 spots on point 6/9/12/3 of the section area between cervical squamous and columnar epithelium shall be carried out; or draw tissue multiple spots for biopsy
Vaginoscopic examination cannot directly diagnose cancer tumor, but can help biopsy to choose right position. It is estimated that if biopsy is performed with the help of vaginoscopic examination, then the diagnosis of early cervical cancer can reach to 98% accurate rate. However, vaginoscopic examination cannot replace scraping cytological exanimation or biopsy, and cannot detect the lesion inside cervical canals as well.
Experts of Modern Cancer Hospital Guangzhou remind that good cervical cancer examination and screening can help people to find cervical cancer in timely manner so as not to delay the treatment for cervical cancer.
