Cervical polyps usually come back. Sometimes, one or more of the symptoms you experience are abnormal bleeding, pain, or spotting. The cause of this is not known with certainty, but it is most likely due to the changing hormone levels in the body, or prolonged infection that has not been cured. The polyp is often removed because it is usually problem-free. The doctor should closely monitor your health to know precisely everything is normal.

Please let me know what was your question. I can provide you with the answer once you have asked the question.

you should see a gynaecologist right away. The presence of a yellowish discharge could bear witness to an infection or inflammation in the reproductive system.
