Tailbone pain is not necessarily cervical cancer and should not be used as an indication of whether it is cervical cancer.
Tailbone pain may appear in the late stage of cervical cancer, but it is also related to pelvic inflammatory disease, lumbar vertebrae, tail vertebrae and many other factors, so it cannot be generalized.
Meanwhile, the typical symptoms of cervical cancer are contact bleeding, discharge with fishy odor, and diagnosis is confirmed by cervical cytology and/or HPV test, colposcopy, and cervical biopsy.
Tailbone pain is very strong, then it is recommended to seek medical treatment in time, it may be caused by advanced cancer involvement, or it may be caused by osteoporosis or pathological conditions in the bones, so you need to find out the cause and treat the symptoms.
