The cervical cancer vaccine is administered in the same way as regular vaccines, which is an injection in the deltoid muscle. However, the scheduling of the subsequent doses of the cervical cancer vaccine differs. For the bivalent cervical cancer vaccine, the second dose is administered one month after the first dose, and the third dose at six months. For the quadrivalent and nonavalent vaccines, the second dose is administered two months after the first, with the third dose given at six months.

Self-exam method for cervical cancer

There aren't many methods for self-examination of cervical cancer. If symptoms such as vaginal bleeding or discharge occur, it is crucial to visit a hospital for a gynecological examination promptly. Of course, the diagnosis of cervical cancer should still rely on the examination by specialist doctors at hospitals. There are cytological examinations of cervical scrapings available, as well as examinations of cervical and endocervical tissue to confirm whether it is cervical cancer or not. Particularly, the examination of cervical and endocervical tissue is the main basis for confirming cervical cancer. Therefore, we should still undertake pathological examinations to confirm whether it is cervical cancer or not, rather than relying solely on self-examination to diagnose cervical cancer.

Cervical cancer leukorrhea characteristics

The characteristics of vaginal discharge in cervical cancer may include the presence of blood in the discharge. This is because cervical cancer often leads to increased vaginal discharge, which may also increase in quantity and might contain streaks of blood or bloody material. The discharge could be thin and watery or resemble rice wash water, and it might have a foul smell. In advanced stages, due to necrosis of the cancer tissue accompanied by infection, there can be a substantial amount of foul-smelling, purulent discharge resembling rice wash water. Therefore, these characteristics of the vaginal discharge are specific symptoms of cervical cancer. If such symptoms occur, it is crucial to seek medical consultation promptly to evaluate for cervical cancer.

Precursors of cervical cancer

The occurrence and development of the cervix is a process from quantitative to qualitative change, evolving gradually to a sudden shift over a long period. The precursor might be the heterotypic zone of the cervix, which is a common site for abnormalities. During the formation of this heterotypic zone, cervical epithelial metaplasia is relatively active, and, compounded by infection with the human papillomavirus and further stimulated by external carcinogens, immature or proliferative squamous epithelial cells may exhibit gradual changes or atypical hyperplasia, potentially leading to sarcomatoid changes in the cervical epithelium. This might be a precursor sign.

Does cervical cancer hurt?

For patients with cervical cancer, the most common clinical manifestations are bleeding during sexual intercourse and irregular vaginal bleeding. Patients who have undergone menopause may also experience irregular vaginal bleeding post-menopause, and some patients may not show any clinical signs at a very early stage. As the cancer progresses, and when it invades nearby organs and metastasizes, it may cause lower abdominal distension and pain, and even more severe pain if the metastatic organs compress nerves or directly invade areas containing nerves.

There are several types of cervical cancer vaccines.

There are three types of cervical cancer vaccines: bivalent, quadrivalent, and nonavalent, and the recommended vaccination ages vary for each. The bivalent cervical cancer vaccine is suitable for females aged 9 to 45; the quadrivalent vaccine is suitable for females aged 20 to 45; the nonavalent vaccine is suitable for females aged 16 to 26. Vaccinations can be scheduled at hospitals within these age ranges. The younger the age at vaccination, the higher the antibody production after receiving the cervical cancer vaccine, meaning the effectiveness is better.
