Urine test may help prevent cervical cancer, finds study

Urine testing may be as effective as the smear test at preventing cervical cancer and could significantly increase participation rates for screening, a study has found.

The research found that urine testing was just as good as the cervical smear at picking up high-risk human papillomavirus (HPV), the virus that causes cervical cancer.

Researchers  said a urine test could help increase the numbers of women who are screened for cervical cancer.

Urine testing could have a role in the developing world, where cervical cancer is up to 15 times more common and smear testing largely non-existent.

Around one in 20 women show abnormal changes which might go on to become cancer and are referred for colposcopy, where the cervix is examined under magnification, allowing abnormal areas to be seen, sampled and treated, before they ever cause cancer, researchers said.

According to the team, cervical smear samples, self-collected vaginal samples and urine samples are all effective at picking up high risk HPV infection.

Cervical cancer is most common in women aged 30 to 35 years. However, the precancerous stage is detectable in the 5-10 years before this, when up to a third of women fail to attend for their smear test.

"We're really very excited by this study, which we think has the potential to significantly increase participation rates for cervical cancer screening in a key demographic group," said the researcher who led the study.

Symptoms of Cervical Cancer

Cervical cancer is a form of cancer which occurs in the cervix or the lower part of the uterus in women, which opens up into the vagina. It has a high rate of being cured if detected early.
Causes of Cervical Cancer: Major cases of cervical cancer are caused by a virus known as the human papillomavirus or HPV. This virus gets transmitted from one person to another by sexual  contact. Abnormal changes in the cervix cells lead to cervical cancer. Usually, cell changes occur in the transformation zone in the cervix as the cells tend to change constantly, thereby leading to cancer.
Symptoms:

  1. Abnormal vaginal bleeding between menstrual periods, after menopause or after having sex.
  2. Pain is experienced during sex.
  3. Abnormal vaginal discharge is noticed.
  4. Abnormal changes in the menstrual cycle.
  5. Anemia due to abnormal bleeding from the vagina.
  6. Recurring pain in the pelvis, back or leg.
  7. Several urinary problems due to the blockage of the uterus.
  8. Urine or stool leakage into the vagina.
  9. Loss of weight.
Diagnosis
 Taking regular Pap smear test is recommended to detect abnormal cell changes so that cervical cancer can be prevented before hand. Other diagnostic tests include Colposcopy and cervical biopsy to determine the presence of abnormal cells in the cervix, Endocervical biopsy and Cone biopsy.


Treatment options available: 
Cervical cancer can be treated when detected at an early stage. The type of treatment depends on the stage and type of cervical cancer. The most common treatment methods are as follows:


  1. Surgery - Several types of surgeries exist and the ideal one depends on the location and severity of the cervical cancer.
  2. Radiation therapy involves the use of high dosage X-rays and implants within the vaginal cavity. This kills the cancer cells and is used in some specific stages of cervical cancer. This therapy is often used with surgery.
  3. Chemo-radiation is a combination of radiation therapy and chemotherapy. This procedure can be used at various stages of cervical cancer.
  4. Chemotherapy involves using medicines for killing cancer cells. It is used in advanced stages of cervical cancer.
