Cervical cancer is a type of cancer that
affects the cervix, which is the lower part of the uterus that connects to the
vagina. It is caused by a virus called human papillomavirus (HPV), which is
spread through sexual contact. HPV can cause abnormal changes in the cells of
the cervix, which may become cancerous if not treated.
Cervical cancer is one of the most preventable
cancers, if detected early and treated appropriately. In this blog post, we
will discuss the symptoms, causes, risk factors, complications, diagnosis,
treatment, and prevention of cervical cancer.
Symptoms of Cervical Cancer
In its early stages, cervical cancer may not
cause any signs or symptoms. However, as it progresses, it may cause:
- Vaginal bleeding after intercourse, between periods, or after menopause
- Abnormal vaginal discharge with a foul odor
- Pelvic pain or pain during intercourse
- Difficulty urinating or defecating
If you experience any of these symptoms, you
should see your doctor as soon as possible.
Causes and Risk Factors of Cervical Cancer
The main cause of cervical cancer is Human
Papilloma Virus (HPV) infection. HPV is a common virus that can infect the skin
and mucous membranes of the genitals, mouth, throat, and anus. There are more
than 100 types of HPV, but only some of them can cause cervical cancer. The
most common types are HPV 16 and HPV 18, which are responsible for about 70% of
cervical cancers.
HPV infection is very common and often does
not cause any symptoms or problems. However, in some cases, it can persist and
cause abnormal changes in the cells of the cervix. These changes are called
cervical dysplasia or precancer. If left untreated, these changes can progress
to cervical cancer over time.
Some factors that can increase your risk of
getting HPV infection and cervical cancer are:
- Having multiple sexual partners
- Having sex at an early age
- Having other sexually transmitted infections (STIs) such as chlamydia, gonorrhea, syphilis, or HIV/AIDS
- Smoking
- Having a weakened immune system due to certain diseases or medications
- Having a family history of cervical cancer
Complications of Cervical Cancer
If untreated, cervical cancer can spread to
other parts of the body and cause serious complications. Some of these
complications are:
- Severe pain
- Kidney failure
- Blood clots
- Bleeding
- Fistula (an abnormal connection between organs or tissues)
- Vaginal discharge
Cervical cancer can also affect your fertility
and sexual function. Depending on the stage and treatment of your cancer, you
may not be able to get pregnant or carry a pregnancy to term. You may also
experience early menopause, vaginal dryness, narrowing of the vagina, or
lymphedema (swelling of the legs due to fluid buildup).
Diagnosis of Cervical Cancer
The best way to diagnose cervical cancer is to
have regular screening tests that can detect precancerous changes or cancer in
its early stages. The screening tests for cervical cancer are:
- Pap test (or Pap smear): A test that collects cells from the cervix and examines them under a microscope for abnormalities.
- HPV test: A test that checks for the presence of high-risk types of HPV in the cervical cells.
These tests can be done in a doctor's office
or clinic. Depending on your age and risk factors, you may need to have these
tests every 3 to 5 years. If your test results are abnormal, you may need
further tests to confirm the diagnosis and determine the extent of your cancer.
These tests may include:
- Colposcopy: A procedure that uses a magnifying instrument called a colposcope to examine the cervix more closely.
- Biopsy: A procedure that removes a small sample of tissue from the cervix for analysis.
- Cone biopsy: A procedure that removes a cone-shaped piece of tissue from the cervix for analysis.
- Endocervical curettage: A procedure that scrapes tissue from the inside of the cervix for analysis.
- Imaging tests: Tests such as X-ray, CT scan, MRI scan, or PET scan that create pictures of the inside of your body to see if the cancer has spread.
Treatment of Cervical Cancer
The treatment options for cervical cancer
depend on the stage and type of your cancer, your overall health, and your
preferences. The main treatment options are:
- Surgery: A procedure that removes the cancerous tumor and some surrounding tissue. The type of surgery depends on how much tissue needs to be removed. It may include simple hysterectomy (removal of the cervix and uterus), radical hysterectomy (removal of the cervix, uterus, part of the vagina, and lymph nodes), or trachelectomy (removal of the cervix and some surrounding tissue, but leaving the uterus intact).
- Radiation therapy: A treatment that uses high-energy beams such as X-rays or protons to kill cancer cells. It may be given externally (from a machine outside your body) or internally (by placing radioactive sources inside your body near the tumor).
- Chemotherapy: A treatment that uses drugs to kill cancer cells. It may be given by mouth, injection, or infusion. It may be used alone or in combination with radiation therapy.
- Targeted therapy: A treatment that uses drugs that target specific features of cancer cells, such as proteins or genes. It may help stop the growth or spread of cancer cells. One example of targeted therapy for cervical cancer is bevacizumab, which blocks the formation of new blood vessels that feed the tumor.
- Immunotherapy: A treatment that uses drugs that stimulate your immune system to fight cancer cells. It may help your body recognize and destroy cancer cells. One example of immunotherapy for cervical cancer is pembrolizumab, which blocks a protein that prevents your immune system from attacking cancer cells.
Prevention of Cervical Cancer
The most effective ways to prevent cervical
cancer are to get vaccinated against HPV and to have regular screening tests.
Other ways to reduce your risk of cervical cancer are:
- Practicing safe sex, such as using condoms and limiting your number of sexual partners
- Avoiding smoking or quitting if you smoke
- Eating a healthy diet rich in fruits and vegetables, especially those that contain beta-carotene, folic acid, lycopene, and vitamin C
- Maintaining a healthy weight and being physically active
Cervical cancer is a serious disease that can
affect your quality of life and survival. However, it can be prevented and
treated if detected early. By following the recommendations in this blog post,
you can protect yourself from cervical cancer and live a longer and healthier
life.
