All you need to know about cervical cancer

Cervical cancer affects the entrance to the womb. The cervix is the narrow part of the lower uterus, often referred to as the neck of the womb.

Cervical Cancer

Cervical cancer affects the entrance to the womb. The cervix is the narrow part of the lower uterus, often referred to as the neck of the womb.

In the early stages of cervical cancer, a person may experience no symptoms at all. As a result, women should have regular cervical smear tests or Pap tests.

A Pap test is preventive. It aims not to detect cancer but to reveal any cell changes that indicate the possible development of cancer so that a person can take early action to treat it.

The most common symptoms of cervical cancer are:

  • bleeding between periods
  • bleeding after sexual intercourse
  • bleeding in post-menopausal women
  • discomfort during sexual intercourse
  • vaginal discharge with a strong odour
  • vaginal discharge tinged with blood
  • pelvic pain

These symptoms can have other causes, including infection. Anyone who experiences any of these symptoms should see a doctor.

Working out the stage of cancer is important, as it helps a person decide the most effective type of treatment.

Staging aims to assess how far cancer has spread and whether it has reached nearby structures or more distant organs.

A 4-stage system is the most common way to stage cervical cancer.

  • Stage 0: Precancerous cells are present.
  • Stage 1: Cancer cells have grown from the surface into deeper tissues of the cervix, and possibly into the uterus and to nearby lymph nodes
  • Stage 2: cancer has now moved beyond the cervix and uterus, but not as far as the walls of the pelvis or the lower part of the vagina. It may or may not affect nearby lymph nodes.
  • Stage 3: Cancer cells are present in the lower part of the vagina or the walls of the pelvis, and it may be blocking the ureters, the tubes that carry urine from the bladder. It may or may not affect nearby lymph nodes.
  • Stage 4: cancer affects the bladder or rectum and is growing out of the pelvis. It may or may not affect the lymph nodes. Later in stage 4, it will spread to distant organs, including the liver, bones, lungs, and lymph nodes.

Undergoing screening and seeking medical attention if any symptoms occur can help a person access early treatment and increase the chances of survival.

Cancer is the result of the uncontrolled division and growth of abnormal cells. Most of the cells in our body have a set lifespan, and, when they die, the body generates new cells to replace them.

Abnormal cells can have two problems:

  • they do not die
  • they continue dividing

This results in an excessive buildup of cells, which eventually forms a lump or tumour. Scientists are not completely sure why cells become cancerous.

However, some risk factors might increase the risk of developing cervical cancer. These include:

  • HPV: This is a sexually transmitted virus. More than 100 different types of HPV can occur, at least 13 of which may cause cervical cancer.
  • Having many sexual partners or becoming sexually active early: The transmission of cancer-causing HPV types nearly always occur as a result of sexual contact with an individual who has HPV. Women who have had many sexual partners generally have a higher risk of HPV infection. This increases the risk of developing cervical cancer.
  • Smoking: This increases the risk of cervical cancer, as well as other types.
  • A weakened immune system: The risk of cervical cancer is higher in those with HIV or AIDS, and people who have undergone a transplant, leading to the use of immunosuppressive medications.
  • Birth control pills: Long-term use of some common contraceptive pills slightly raises a woman's risk.
  • Other sexually transmitted diseases (STD): Chlamydia, gonorrhoea, and syphilis increase the risk of developing cervical cancer.
  • Socio-economic status: Rates appear to be higher in areas where income are low.

Cervical cancer treatment options include surgery, radiotherapy, chemotherapy, or combinations of these.

Deciding on the kind of treatment depends on several factors, such as the stage of cancer, as well as age and the overall state of health.

Treatment for early-stage cervical cancer, when cancer remains within the cervix, has a success rate. Further cancer spreads from its original area, the lower the success rate tends to be.
