The importance of cervical cancer screening: What you need to know
Cervical cancer screening (including HPV and Pap tests) is a critical tool in the early detection of precancerous cells in the cervix. It can even prevent this type of cancer entirely by enabling doctors to administer treatment before symptoms develop.
Indeed, according to the U.S. CDC, the use of the Pap (Papanicolaou) test has even resulted in a 70% decrease in this cancer's incidence and mortality rate.
By understanding the importance of screening for cervical cancer, you can be more proactive in safeguarding your short- and long-term reproductive health. It can also protect the overall quality of your life and even your life itself, as this type of cancer, albeit highly treatable, can also be deadly.
Following cervical health tips and guidelines for early screening methods can help you prevent this cancer, find it early, and live a longer, more fulfilling life.
What Are the Warning Signs of Cervical Cancer?
One of the biggest concerns about cervical cancer is that it's a silent killer. As a study published in the journal Nature.com points out, it kills without almost any symptoms in women, particularly in the early stages of the disease.
If symptoms occur, they usually indicate the disease has already advanced to more dangerous stages. Advanced cervical cancer signs and symptoms include:
- Abnormal vaginal bleeding, which can occur between menstrual periods, after menopause, or after sexual intercourse
- Unusual vaginal discharge, usually tinged with blood
- Pelvic pain, which may present as pain in the pelvic region or during intercourse
- Back pain
- Urinary incontinence
- Increased need to urinate or more frequent urination
The fact that this cancer is often asymptomatic at its earliest stages further underscores the importance of cervical cancer screening.
Can You Have Cervical Cancer Without HPV?
HPV, which stands for human papillomavirus, is a highly prevalent sexually transmitted virus. It affects the skin and mucous membranes and can cause cervical infections.
According to the World Health Organization, persistent HPV infections of the cervix can lead to precancerous lesions, which, if not treated, cause about 95% of cervical cancer cases.
The remaining cases can arise from other causes and factors that are non-HPV-related. Health professionals refer to these as HPV-negative cervical cancer.
At What Age Is Cervical Cancer Most Common?
Cervical cancer often occurs in people over 30 years old, as explained by this web page discussing RCCA oncology services. However, it can develop in younger women, too, as well as in individuals over the age of 65.
Why Is Cervical Cancer Screening Crucial?
Considering that this disease is typically asymptomatic (without symptoms), screening is critical for early cervical cancer detection and treatment.
When diagnosed early, cervical cancer is at its most treatable, even curable. Treatment for early-stage cancer is also less invasive, resulting in shorter recovery times and better outcomes.
Preventing Cervical Cancer
Cervical health screening benefits women by helping reduce their risk of cancer of the cervix. It aims to detect high-risk HPV infections and identify precancerous cell abnormalities or changes that can ultimately lead to invasive cancer.
By determining the presence of these abnormalities, healthcare professionals can then remove them before they progress to cancer.
Treating or Curing Cervical Cancer Early
Cervical cancer screening is the most definitive way to find this disease, the identification of which is best at its earliest stages. When caught early, treatment can begin right away while the cancer is still at a localized stage (confined within the cervix).
Localized cancer cases have higher curability and survival rates.
The latest data from the American Cancer Society places the five-year relative survival rate for localized cervical cancer at 91%. It drops to 62% for regional cases (cancer that has spread around but is still close to the cervix) and 20% for distant cases (cancer that has spread to other parts of the body).
Allowing for Less Invasive Treatments
The earlier healthcare professionals catch cervical cancer, the less invasive the treatments they can use to treat or cure it.
There are surgical procedures, for instance, that can preserve fertility, such as cervical conization and radical trachelectomy. They're less intensive than a traditional hysterectomy, which involves removing:
- The entire uterus
- The cervix
- Nearby lymph nodes (in some cases)
Brachytherapy is another treatment option for cervical cancer that's less invasive than conventional chemotherapy or radiation therapy. It's a highly targeted form of radiation that delivers high-dose radiation to the tumor, sparing the surrounding healthy tissue from damage.
Frequently Asked Questions
What Causes HPV-Negative Cervical Cancer?
HPV-negative cervical cancers can result from genetic mutations. Risk factors, such as chronic inflammation and smoking, further increase the risk of developing them.
Who Should Undergo Cervical Cancer Screening?
According to the National Cancer Institute, the frequency at which women should undergo cervical cancer screening and the type of tests to get depend on their age and health history. The general recommendation is to get a Pap test by the age of 21 and to get it every three years until the age of 29.
Women between 30 and 65 years old should consider getting a Pap test every three years, an HPV test every five years, or an HPV/Pap cotest every five years. An HPV/Pap cotest combines both an HPV and Pap test.
Is There a Vaccine for Cervical Cancer?
There is: the HPV vaccine. It safeguards against most cases of cervical cancer and genital warts. It can also protect against other types of cancers caused by HPV (e.g., anal, penile, vaginal, and vulval cancers).
The ideal age to get the HPV vaccine is before someone becomes sexually active. The primary reason is that its goal is to prevent new infections, so if a person gets an HPV infection, it may not be as effective.
Gardasil 9 is a specific type of HPV vaccine approved by the U.S. Food and Drug Administration (FDA). Individuals aged nine to 45 can get it.
Cervical Cancer Screening Saves Lives
Cervical cancer screening, including HPV and Pap tests, is crucial to preventing, finding, and stopping cancers of the cervix. It allows for early treatment, even cure, and the use of less invasive procedures.
Anyone with a cervix who is 21 years or older should therefore consider undergoing these tests, as they can help save lives.
