Cervical dysplasia is an abnormal change in cells of your cervix . It needs to be monitored by a health care provider, because it could progress to cervical cancer if left untreated. Regularly scheduled Pap smears are an important detection tool, because many women do not experience any symptoms of dysplasia. Smoking and a weakened immune system can make you more vulnerable to developing cervical dysplasia.


Cervical dysplasia is usually linked to a common sexually transmitted infection called HPV (human papillomavirus). Different types of HPV can produce different reactions in the body, including cervical dysplasia. HPV can take years to show signs in the body, so even if you haven’t been sexually active in a long time, it’s important to have Pap smears. Women who have sex with women can transmit HPV to their partners, so they should also make sure to have Pap smears.

Diagnosis and treatment

Cervical dysplasia is first detected through Pap smears. If you have a Pap smear that is abnormal, your doctor may recommend you have a colposcopy, a procedure using a special microscope to examine your cervical cells more closely. During a colposcopy, a bit of tissue can be removed and sent to a lab for examination. This is called a cervical biopsy.

Treatment depends on the size and severity of the affected area. The goal is to be the least invasive but the most effective in removing the problematic cells:

  • cryosurgery: liquid nitrogen is applied to the area to freeze the cells, which then die.
  • laser treatment: a laser light beam removes abnormal tissue.
  • loop electrosurgical excision procedure: a fine wire charged with an electrical current removes the tissue.
  • cone biopsy: a cone-shaped cut removes the abnormal tissue.

Untreated, dysplasia may lead to cervical cancer, which can progress faster in women with HIV than in women without the virus. Women with lower CD4 counts are more vulnerable to dysplasia. HIV treatment may decrease the risk of developing cervical dysplasia in women with HIV because it reduces viral load and increases CD4+ counts, thereby strengthening the immune system. Antiretroviral drugs may also improve cervical dysplasia by causing abnormal cells to shrink and disappear.


You can lower your risk of cervical dysplasia by doing the following:

  • Practise safer sex
  • Get regular Pap tests
  • Quit smoking
  • Talk with your doctor about HIV treatment
