Self-detection methods of cervical cancer are unreliable, and individuals should not believe in them blindly. Cervical cancer is the second most common gynecological malignant tumor in terms of incidence rate, second only to breast cancer, and in recent years, its incidence has shown a trend of rejuvenation. Before treating cervical cancer, the disease must be diagnosed clearly through scientific examination, while the so-called self-examination method is unreliable and has no scientific basis, so women should not blindly believe in the so-called self-examination method. Individuals who suspect that they are suffering from cervical cancer should be examined and diagnosed through colposcopy, HPV test, gynecological examination, imaging examination and pathological examination. Comprehensive and scientific examinations can not only confirm the diagnosis of cervical cancer, but also understand the severity of the disease and the actual lesions, providing an accurate basis for the next step of treatment. Individuals diagnosed with cervical cancer should cooperate with the treatment as soon as possible, so as to prevent the condition from deteriorating and bringing more harm.
