It is not common but when found in early stages, it can often be cured.
As such, regular preventive care is the most important ways to maintain your vaginal health. If you wait to see a doctor only when you notice a problem, it may be too late.
However, the Cancer Society noted few symptoms every woman should consider in relation to vaginal cancer:
Abnormal bleeding through the vagina: Experts stated that abnormal bleeding could happen after douching even when you are not having your menstruation or after intercourse.
Recurrent abnormal discharge: Some women have it in mind that discharge is normal. It is, but not all so if you notice any that is heavy, smelly, with colour or with itching, burning, or swelling please see your doctor.
Watery vaginal discharge or severe pain or bleeding after intercourse: This is an indicator that your cervix needs to be checked.
Lastly, do not ignore any lump or mass in your vagina. Any of these signs indicate that something is wrong somewhere and as such, it should not be neglected. Please see a gynaecologist even if you have been getting regular pap tests.
If it is an infection, it would need to be treated. If it is cancer, ignoring symptoms might allow it to progress to a more advanced stage but when detected early, there are higher chances of effective treatment.
