Are white discharge with vaginal inflammation some symptoms of cervical cancer?

Likely infection. Vaginitis or cervicitis ( inflammation on the vaginal canal wall or inflammation on the cervix) would give the same exact symptomsi.Ie..- vaginal discharge, redness, itchiness/ inflammation etc. Thiis's likely caused by infection ( bacteria, yeast) , chemical irritant (douche, soap ) etc.See you gynecologist for examination. Dont forget to do a pap smear to screen for cervical cancer- as recommended.
Infection more likel. Vaginal inflammation is not a usual symptom of cervical cancer, except in late stage, when it may have spread to the vagina. In any case, you should see your doctor and get the inflammation treated and a pap smear.
