Human Papilloma Virus And The Prevalence Of Cervical Cancer

The most common sexually transmitted infection (STI) is human papillomavirus (HPV) (CDC, 2013). Over half of sexually activity people will become infected with HPV at some point in their lifetime (National Cancer Institute, 2012). HPV can fall into two categories: low-risk HPV and high-risk HPV (National Cancer Institute, 2012). Low-risk HPV, also known as HPV types 6 and 11, cause about 90% of genital warts (National Cancer Institute, 2012). High-risk HPV, also known as HPV types 16 and 18, causes about 70% of cervical cancer (National Cancer Institute, 2012).

Prophylactic vaccination against high risk human papilloma virus 16 and 18 represents an exciting means of protection against HPV related malignancy. However, this strategy alone, even if there is a level of cross protection against other oncogenic viruses, cannot completely prevent cervical cancer. In some countries cervical screening programs have reduced the incidence of invasive cervical cancer by up to 80 percent although this decline has now reached a plateau with current cancers occurring in patients who have failed to attend for screening or where the sensitivity of the tests have proved inadequate. Cervical screening is inevitably associated with significant anxiety for the many women who require investigation and treatment following abnormal cervical cytology. However, it is vitally important to stress the need for continued cervical screening to complement vaccination in order to optimize prevention in vaccines and prevent cervical cancer in older women where the value of vaccination is currently unclear. It is likely that vaccination will ultimately change the natural history of HPV disease by reducing the influence of the highly oncogenic types HPV 16 and 18. In the long term this is likely to lead to an increase in recommended screening intervals. HPV vaccination may also reduce

HPV is the number one sexually transmitted infection (STI) in the United States, and anyone who is sexually active is at risk of contracting the virus. HPV is transmitted through intimate skin-to-skin contact with someone who has the virus, and it is so common that most all sexually active men and women encounter a strain without ever knowing they’re infected (CDC). There are many strains of the HPV virus, some of which don’t cause cervical cancer. To help understand and classify the types of HPV, the terms low-risk and high-risk HPV are used. Some

Cervical cancer is the leading cause of cancerous death, in women, since 1950. Approximately 200,000 cervical cancer patients die each year in developing countries. Strains like HPV 16 and 18 cause about 70% of cervical cancer in women– one of the top causes of death in the world (WebMD, 2010, p.1). In the Unites States, about 10,000 women acquire the disease and 3,700 die annually Human Papilloma Virus (HPV) is directly associated as a cause of cervical cancer. This virus affects the skin and genital area and, in some cases, it can also infect the throat and mouth. Since the HPV is passed from one person to another through skin-to-skin or sexual contact, sexually active people are more prone to this virus. Merck

Human Papillomavirus(HPV) is the most common sexually transmitted infection in the United States, according to Centers for Disease Control and Prevention(CDC) around 20 million people are infected with HPV and additional 6.2 million people are newly infected every year. According to National Health and Nutrition Examination Survey in 2003-2004 among sexually active women (57% of 14 to 19 years and 97% of 20 to 59 years) HPV was highest prevalent in youngest age group (40% of 14-19 years and 50% of 20-24 years). Infection rates decrease after age of 24 years. There are more than 100 types of HPV viruses out of which 40 cause genital infections. Out of

Human Papillomavirus (HPV) is a double -stranded deoxyribonucleic acid (DNA) virus that only infects humans with an attraction to both cutaneous and mucosal surfaces such as the cervix, anus, tonsil, and oropharynx (Clark, 2013). HPV is a type of oncogenic virus that goes into the cells and can cause several diseases. Over the years, research has surfaced connecting genital HPV to several types of cancer. There are over a hundred strains of HPV but the most high risk strains, 16 and 18, have been shown to cause vulvar, vaginal, anal, and the most concerning, cervical cancer (Chan, Ng, & Wong, 2012). Genital HPV

Human Papilloma Virus (HPV) accounts for the third most prevalent cancer in females worldwide,15 as it is the most common sexually transmitted infection (STI).2 There are more than 100 subtypes of HPV; 16 of those subtypes are known to be high-risk.15 HPV is a crucial precursor to cervical cancer in 99.8% of those affected,2 with subtypes 16 and 18 being the most common types.15

Human papillomavirus (HPV) is one of the most common sexually transmitted viral infections in the United States. There are nearly 1 out of 4 women who have been diagnosed with HPV (CDC, 2015). The Centers for Disease Control and Prevention (CDC) reported that at least 80% of women acquire a genital HPV infection by the age of 50 (CDC, 2015). HPV is an important topic that needs to be discussed because it has been estimated that 6.2 million cases of HPV has been reported (CDC, 2015). HPV is one third of all new sexual transmitted infections (CDC, 2015).

In the United States, cervical cancer is known as one of the most common cancers amongst females and it is estimated that 1/3 of the females diagnosed will die (Parkin, Bray, Ferlay, & Pisani, 2005). HPV 16 is the most common detected virus in cervical cancer patients, but there are 14 HPV types that are considered high-risk (Parkin, Bray, Ferlay, & Pisani, 2005). HPV is related to cervical cancer as the virus changes the cells of the cervix and causes cervical dysplasia, which untreated, leads to cancer (Dizon & Krychman, 2010). Examining the problem from a global perspective, Biological Study on Cervical Cancer (IBSCC) study group, concluded that “HPV DNA was detected in 93% of the tumors and … HPV 16 was present in 50% of the specimens…” (Bosch, Manos, Muñoz, Sherman, Jansen, Peto & Shan, 1995). This group collected samples of 1000 patients whom were diagnosed with stage 3 cervical cancer from 32 hospitals in 22 countries (Bosch, Manos, Muñoz, Sherman, Jansen, Peto & Shan, 1995). As, represented earlier with current statistics, it’s evident that more people are diagnosed each year with cervical cancer that have HPV present

The human papilloma virus (HPV), a sexually transmitted infection, is considered necessary for the development of cervical cancer condition. HPV types 16 and 18 are responsible for the vast majority of cervical cancers. Therefore, HPV infection is more likely to be in women who start having sex at an early age and have multiple sexual partners or a partner who has had many sexual partners. This is because their behaviour is more likely to be exposed to HPV. However, a woman with only one partner can get HPV if partner has already been in contact with the virus (Public Health England, 2013).

Human papillomavirus is a virus that can cause warts, or as the name suggests papilloma, along with some types of cancers. Papillomas are benign tumors that in this case are caused by the human papillomavirus. Human papillomavirus is a group of over a hundred viruses with at least fifteen that are a high risk for causing cancer. HPV is usually passed from person to person during sexual intercourse, though it usually is addressed as a virus that can be passed via skin-to-skin contact. Human papillomavirus has been linked to cancers of the reproductive system, along with the head and neck. Cervical cancer is probably the most well known cancer that comes from certain strains of HPV. The strains of HPV that cause cervical cancer first start off as cervical dysplasia and may develop into cancer, but doesn’t always. Cervical dysplasia is the abnormal change to ones’

The most common sexually transmitted infection in the U.S is Human Papillomavirus (HPV). HPV is often asymptomatic and benign. However, it can lead to serious complications. It can cause genital warts, bumps in the genital area that can vary in size and are often painful and itchy. Furthermore, HPV can cause several cancers such as cervical, oropharyngeal, or cancers of the genitals (vulva, vagina, or penis). These cancers often don’t appear for years after contraction of the virus. HPV is spread through sexual/skin to skin contact (vaginal, anal, or oral) with an infected person, regardless if the person is symptomatic. Both females and males can carry the disease. Most symptoms associated with HPV affect both men and women, such as genital

According to the Centre for Health Protection of the Department of Health (2011), cervical cancer becomes the tenth commonest cancer in Hong Kong in 2008. Cervical cancer usually arises from sexual activity and human papillomavirus (HPV) (Bellentir, 2002). In this essay, Human papillomavirus would be further discussed. For example, the signal transport pathway of HPV 16 and HPV 18, which many scientists believe that they are closely related of causing cervical cancer, as well as the HPV vaccine and chemotherapy of cervical cancer, would be discussed.

Human Papillomavirus (HPV) is an extremely commonly detected DNA virus widely known as the most cause of HNSCC, in most cases, the virus doesn’t cause any health problems and it goes away on its own, however, HPV can sometimes cause health problems such as cancer and warts. Furthermore, the world health organisation (WHO) reported that HPV accounts approximately 600,000 cases of oropharyngeal cancer, anal cancer, cervix cancer as well as genital wart worldwide.

The Human Papillomavirus (HPV) is a set of 150 connected viruses. This group of viruses is very large and thus each HPV virus is assigned a number that is called the corresponding HPV type. The names of such HPV types are called after warts it produces as a visible sign of the infection.1 One very easy way to spread HPV viruses is by means of sexual contact. In addition, more than 40 HPV types are involved in the sexual transmittance of the infections. There are two different categories for sexually transmitted HPV types: low-risk and high-risk. Low-risk HPVs will not cause cancer but cause warts to grow on the skin or other openings on the body such as genitals and mouth. On the other hand, high-risk HPVs do lead to
