TCT is normal but I have cervical cancer

People nowadays have realized the importance of physical health. Therefore, both men and women should have regular physical examinations. Especially for women, gynecological diseases are very common and the uterus is often prone to disease problems. Cervical cancer is a common disease. When women undergo physical examinations, the uterus is the focus of the examination. TCT is a test to examine the uterus, but how can the patient have cervical cancer when the TCT is normal?

TCT, or thin-layer liquid-based cytology, is a cytological examination that uses a special sampling brush to penetrate deep into the cervical canal and rotate to collect cervical cell samples, which are then observed under a microscope for changes in cell morphology.

From a methodological point of view, there is indeed a possibility of false negatives in cervical TCT, which means that the cervical TCT test results may be normal, but in fact there is a possibility of cervical precancerous lesions. This is because errors may occur in the process of collecting cervical cells, making films, and doctors reading films.

The cervical mucosa is also called the endocervical mucosa. Its surface is covered with a single layer of columnar epithelial cells that can secrete mucus. The outside of the cervix from the external cervical os to the top of the vaginal vault is covered with stratified squamous epithelial cells. There is a junction between the columnar epithelium of the endocervical mucosa and the squamous epithelium of the cervical vagina. The cervical mucosa undergoes cyclical changes under the influence of ovarian hormones. The junction of the columnar epithelium and squamous epithelium of the external cervical os is a common site for cervical cancer.

At the same time, since cervical adenocarcinoma is mostly endocytic and often extends to the lower segment of the uterus and deep into the myometrium, it is difficult to obtain samples. The poor sensitivity of cervical cytology screening and the low positive rate of endocervical curettage make early detection of cervical adenocarcinoma more difficult.

Therefore, early cervical adenocarcinoma can almost only be prevented by increasing vigilance against high-risk factors, injecting HPV vaccines, regularly screening for precancerous lesions, and actively treating precancerous lesions. HPV testing plays a very important role in the prevention of cervical adenocarcinoma.

Women should go for regular check-ups. Regular check-ups can detect diseases and provide timely treatment, which will greatly increase the possibility of cure. Although cancer is very scary, today's medical technology has been constantly improving. We should be full of confidence and not give up treatment. For female patients suffering from cervical cancer, their families should also be around to give more encouragement and support to help them overcome cancer. It is recommended to exercise more often to improve the body's immunity.
