If there are small bumps at the cervix, they are likely to be caused by one of the following conditions: first, polyps of the cervix, due to long-term chronic inflammatory stimulation of the cervix, resulting in local tissue hyperplasia of the cervix and the formation of redundancies, which are often bright red and cause bleeding at intercourse during sex. The second, the cervical nuchal cyst, is also due to long-term chronic inflammatory stimulation of the cervix, so that the local glandular ducts of the cervical mucosa are blocked, so that the fluid inside cannot flow out, forming small bumps, i.e. small nuchal cysts, which can be treated by laser or microwave therapy. The third is the presence of warts on the cervix, which is a sexually transmitted disease through sexual contact. So if you find a small bump on your own at the cervix, be sure to go to the hospital for a detailed examination so that your doctor can make a preliminary diagnosis of what is causing it under visual observation before giving the next step of treatment.
