Today saw a report, and caused widespread concern and discussion, said that cervical cancer screening is expected to 7 seconds of rapid determination, namely to have breath direct detection of cervical cancer, so, it can be powerful.
The researchers at the Hefei Institute of Physical Science.CAS have developed a real-time online breath mass spectrometer, which allows direct measurements of exhaled breath in a single patient in 7 seconds. They through breath detection of 13 cervical cancer patients and 34 healthy people, four kinds of Statistics found that expiratory mass characteristic ions distinguish cervical cancer, for distinguishing true positive rate of cervical cancer and true negative rate reached 92.3% and 88.2% respectively. The research results are published in the international authoritative magazine "Analytical and Bioanalytical Chemistry", the study itself is certainly worthy of belief.
To identify the characteristic ion of breath mass spectrum in cervical cancer patients? Can cervical cancer be detected by real time? I don't know much about this technology, so I don't comment on it for the moment.But certainly, this is just a research result, providing a possibility, and whether it will eventually be put into practical use, is not yet to come to a conclusion, and I certainly hope so.However, for the moment, screening for cervical cancer still relies mainly on cervical cytology and HPV testing.
Cervical cancer is one of the most common malignant tumors of women, in addition to breast cancer after second female malignant tumors, both can be said to be Confidante killer, but fortunately, both breast cancer and cervical cancer, are relatively easy for early detection of malignant tumors, and have a more effective screening method.
How to screen for cervical cancer? According to the comprehensive guidelines for screening of cervical cancer, the American Cancer Society, the American Society of the American Society for colposcopy and cervical pathology, clinical pathology of American College of Obstetricians and Gynecologists, the national comprehensive cancer network released, gives the following suggestions:
(1) screening has age requirements, and not all women of all ages need to be screened every year.
(2) women recommend screening at the age of 21, and women younger than 21 years of age do not need to be screened;
(3) more than 21 women under the age of 29, every 3 years to do 1 cervical cytology, namely cervical smear, cervical smear, the age of women is not recommended for routine detection of human papilloma virus HPV, do not recommend screening, cytology and HPV HPV course and if the cytology positive, according to the situation can also consider the human papilloma virus HPV detection;
(4) more than 30 women under the age of 65, every 5 years, 1 times the human papilloma virus HPV detection and cervical cytology screening, the first recommendation of course, can also be every 3 years or 1 cervical cytology cytology, if the result is positive, then taking into account the human papillomavirus HPV detection;
(5) if the results of previous screening are normal, more than 65 year old woman can stop screening, but should meet the following conditions: after 10 years of the last 5 years, 3 consecutive cervical cytology screening results were negative, or 2 consecutive human papilloma virus HPV detection combined with cervical cytological test results were negative. No, and high grade squamous intraepithelial lesions and adenocarcinoma in situ or a history of cancer.
The above is for the general risk women, if it is high-risk women, screening should be more frequent. If the above screening measures are found abnormal or suspicious abnormalities, should be further considered colposcopy according to specific circumstances, if necessary, take biopsy, and then according to the pathological results of biopsy to do the corresponding treatment.
