Cervical cancer: Prevention is simple

Just get to know HPV screening

Did you know that for Thai women, cervical cancer is second only to breast cancer in terms of the number of sufferers? However, cervical cancer is a form of cancer that if found in its pre-cancerous cells can be prevented from developing, and cured. This is done through care and attention to one’s health, regular internal checkups, and last but not least, HPV cancer screening. Once completed, HPV DNA cancer screening can alleviate any anxieties about this form of cancer.

HIGHLIGHTS:

  • Each year, around 6,000-8,000 Thai women contract cervical cancer and mortality rates are 8-10* women per day on average. 1
  • Any woman who has had sexual intercourse has an 80-90% risk of contracting the HPV virus during her lifetime. (However, the virus may or may not be the type that causes cervical cancer.)
  • All women who are at sexual maturity should undergo screening for cervical cancer. If all these women were to be screened, up to 15% of them would test positive for the high risk HPV virus (they would, therefore, also be at risk of developing cervical cancer).

 

Prevention is simple

If we are fit and healthy, it is unlikely HPV will able to affect us.

5 ways to ensure that the HPV virus, a leading cause of cervical cancer, is kept at bay:

  1. Diet: Fit and healthy people also need a balanced diet incorporating all of the 5 main food groups in moderation. This way, the body will receive the appropriate amounts of vitamins and minerals it needs to sustain a strong immune system.
  2. Exercise: Another way to improve the body’s immune system is through exercise. Regularity should be emphasized with sessions lasting around 30 minutes each time. Additionally, active exercise that burns energy should be undertaken at least 2–3 times per week because this will help to keep the body fighting fit. We can see this when someone who exercises regularly hardly ever seems to catch a cold.
  3. Rest: We need to get the right amount of good quality deep sleep. Waking up with a headache or not getting enough sleep are both referred to as bad quality forms of sleep.
  4. Stress: Most importantly, ‘Don’t stress!’. When we feel stressed, it has a knock-on effect on our immune system and causes our body to become sick easily allowing whatever sickness we have to spread easily throughout our weakened system. Be especially careful of the stress that is not so obvious, such as stomach complaints and stomach aches as these maybe our body’s way of signing us. The worse our eating habits are, the higher the chances of this happening. Alternatively, people with constipation should take it as a sign that the body may also be accumulating stress in some way.
  5. Cigarette Smoking: Whether smoking ourselves or inhaling smoke from those around us, it is all bad because it can weaken our bodies and strengthen the HPV virus. Generally, women who regularly smoke themselves or passively smoke will have low immunity levels, especially with regard to the area where the cervical mucus is located, which causes the virus to develop quickly. Furthermore, statistics show that women who smoke are up to 3 times more likely to develop cervical cancer than those who don’t.

All women are at risk of contracting the HPV virus!

Each year, between 6,000 and 8,000 Thai women develop cervical cancer, with 8 -10 women losing their lives to the disease each day.2  All women who have engaged in sexual intercourse are at risk of developing cervical cancer as almost 100% of cervical cancer cases are caused by the HPV virus because of how easily it is contracted. Aside from being sexually transmitted, the virus is also transmitted through contact alone (this contact is possible through a carrier bringing the virus into contact with the vagina). What is worrying is that once contracted, the virus may not display any outward symptoms such as pain, aches or any form of scarring, which means that by the time women find out they have the HPV virus, it may have taken hold for some years already.

HPV = The only cause of cervical cancer

While cervical cancer is exclusively caused by the HPV virus, only certain strains of the virus cause cancer. There are only 15 strains which cause the cancer from a total of 100 strains of the HPV virus, with strains 16 and 18 being particularly dangerous.

What is HPV Testing?

When carrying out an HPV test, the doctor will place a special device inside the vagina and inspect both the cervix and the vagina paying careful attention to the area of the cervix, which the virus prefers because it is where the cells actively reproduce. The virus will take over this area and cause some irregularities but the effects will be negligible and invisible to the naked eye. Symptoms of the irregularity will not present themselves: no bleeding will occur and any pelvic pain will be completely unrelated.

An assessment called a Pap Smear should be carried out alongside to identify the changes or any irregularities in the cells. This test is good for finding cancer cells or cells that may become cancer. However, Pap test alone will not be able to identify the virus itself and there is a chance too that 15–20% of pre-cancer signals will also be missed. Nevertheless, innovations in medical techniques mean that evaluations of HPV testing are possible and where the HPV virus is found, doctors can now identify exactly which strain it is and whether or not it has the potential to cause cervical cancer.

Even when the HPV virus has been in our body for a decade, it’s sequence is completely treatable if we can identify it.

Since HPV virus infection and precancerous cells are symptomless, most people will be unaware they even have it unless they undergo screening. This means that precancerous change may be left untreated for years with the patient only finding out about it once they already have cervical cancer. Hence, undergoing HPV DNA screening and carrying out a Pap Smear test will help to identify the virus and precancerous cells, which if treated appropriately, will definitely reduce the chances of developing into cervical cancer.

Two key factors that have an effect on the development of cervical cancer:

  • Contracting the HPV virus: This virus causes cervical cancer, but it must be a particularly high-risk strain of the virus in order to do so. There are 15 such strains of the HPV virus, and of those 15 strains, some are stronger and therefore higher risk than others. Hence, if someone has already contracted the HPV virus, the chances of recovery are dependent on the severity of the strain they have contracted.
  • Our immune system: With regard to ‘viral infections’, there are usually no forms of medication available that directly attack the virus. Whether it can be defeated depends on when our immune system is able to kill the virus off by itself, just as when we suffer from a common cold. Factors which will slow our immune system’s response to infections include not getting sufficient rest, a weakened physical state, and stress. For example, when people who suffer from herpes start to feel stronger, get enough rest and drink plenty of water, they will see the herpes disappear. Fortunately, this type of infection has clear signs that we can see developing and subsequently clearing up after we have recovered from them, whereas the HPV virus has no outward signs. Moreover, it takes months or even years for the body to defeat this particular type of infection, with 60-70% of people being able to control the virus without treatment.

Why is cervical cancer still a possibility even after screening?

Since the development of the precancerous cells are particularly slow and sometimes takes years to fully develop to cancer, this is the only viral consequence that can be directly treated and cured if caught early enough. For this reason, patients who develop cervical cancer include those who have not undergone screening in a long while, those who underwent screening but failed to receive their results, or those who underwent screening and received results that identified an irregularity but failed to undergo any treatment because the change was symptomless. Some people even believe that just screening and getting back normal results once is enough to cover them for the rest of their life.

“Almost all women have the HPV virus”

This is quite shocking. Statistics gathered from a number of sources show that:

  • Women who have engaged in sexual intercourse have an 80-90% chance of contracting the HPV virus at some point in their life (although the strain that they contract may or may not be a strain responsible for causing cervical cancer).
  • From the first time that a woman engages in sexual intercourse, regardless of whether she has one lifelong sexual partner or does not have sex again for many years, statistics show that half of all women will come into contact with the HPV virus in the first 2 years after intercourse.
  • Each woman may have come into contact with the virus and subsequently recovered from it many times already without ever knowing that she has done so. This is because the HPV infection is symptomless, meaning that women can be completely unaware that they have contracted it. Whether or not their bodies then defeat the virus depends on numerous factors.

If all women who are at sexual maturity and have been sexually active were to undergo screening for cervical cancer, up to 15% of them would test positive for the high-risk strain of the HPV virus capable of causing cervical cancer.

Did you know?

Men can also contract the HPV virus but the chances of identifying the virus in males is very low. They are actually only carriers of the infection. So HPV screening is currently not a mandatory screening in men.

If we can track the progress of this virus, prevention is simple.

  • Women who have never engaged in sexual intercourse may have a low risk of developing cervical cancer.
  • The primary form of prevention available is to protect against contraction of the virus through a HPV virus vaccination. This type of vaccination has been available for over 10 years in Thailand. Recently, the vaccinations have been targeting the 2 most aggressive forms of the virus which are responsible for causing over 70% of all forms of cervical cancer, namely strains 16 and 18. Therefore, prevention prior to contact with either of these 2 forms is the best option with vaccines available that can be administered to children as young as 9-10 years old. Furthermore, from research into the virus over the last 10 years, it has been found that children do not need to receive the full course of 3 vaccinations which adults must receive to be fully protected. If the child is under 15 years of age, she only requires 2 HPV vaccinations and this gives her 100% protection against the 2 strains of the virus which cause cervical cancer.
  • However, if the child is over the age of 15, it is still recommended that the full course of 3 vaccinations be carried out.
  • Secondary prevention refers to cervical cancer screening techniques which may be carried out in order to identify the disease or virus before it can develop into cancer.
    • A Pap Smear test is an assessment which can identify all changes before the development of cancer, and therefore can provide a chance to seek treatment and cure the irregularity.
    • HPV virus screening, which is commonly referred to as a HPV Test, are capable of identifying the HPV virus through examining the DNA or MRNA. After examining the DNA or MRNA of the virus, if results come back positive, this shows that a strain of the virus, which causes cervical cancer has been found, whereas a negative result shows that these strains are not present. HPV Tests or HPV screening are currently capable of determining the exact group or strain of the virus found.
    • Identifying the HPV virus via a urine analysis is a new form of cervical cancer screening. It has been developed to take cells found in urine and screen them for HPV DNA. Such an assessment can be a viable alternative for women who may be too embarrassed or scared to undergo a lithotomy examination.
  • Prior to an internal examination you are only required to avoid making an appointment during the menstruation period, refrain from sexual intercourse and cease the use of medication used to treat vaginal dryness for a period of at least 1-2 days prior to the examination. These examinations should be carried out annually and, in cases where an irregularity of risk factor has been identified, it is highly recommended that all follow-up doctor’s appointments be attended.

Once HPV screening has been carried out, the next screening is not necessary until 3 years later.

Nowadays, many countries carry out HPV DNA screening as their standard form of screening for cervical cancer. Those who return negative results do not have the strain of virus which causes cervical cancer and do not need to screen again until 3 years later, during which time no assessments are necessary because cancer is unlikely to develop within those 3 years. Once the 3 years have elapsed and it is time to screen again, any irregularity that may be found will only be minor and will likely be completely treatable. As a rule, it is advised that Pap Smear test and pelvic examination be carried out annually, whereas HPV Tests are not as frequently required.
