Cervical Cancer : A Preventable Death

HeLa cells have had a positive influence on medicine in many ways including with giving us knowledge about the human papillomavirus (HPV) DNA and HPV18-positive. HeLa cells have been linked to changes in microRNA expression. Since HPV18 has been associated with very aggressive adenocarcinomas, this finding may explain why Dr. Gey was surprised by the prolific growth of HeLa cells in culture. Routine Papanicolaou smear screening may not detect rapidly progressive cervical carcinomas; the new HPV vaccine holds the promise of preventing these tumors. (Hutchins).

The human papillomavirus remains one of the highest common sexually transmitted infections in the United States. The human papillomavirus dates back to the nineteen hundreds. Scientists during the nineteen hundreds did not comprehend on why people who had sexually transmitted infections also had cancer. It was not until the nineteen-eighties, that a scientist discovered that the human papilloma virus caused cancer (Preventing Cervical Cancer). Moreover the human papillomavirus causes genital warts in both men and women. In the year two thousand and six, a scientist generated two vaccines that protect the human body from contracting the virus. The Food and Drug Administration approved Gardasil and Cervarix since they are clinically tested

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) is a double stranded DNA virus. There are many genotypes HPV and some of them are oncogenic. They have envelope proteins E6 and E7 on their cell wall which are associated to initiate cancer. Anogenital lesions associated to HPV are divided into ‘low-risk’ types (6, 11, 34, 40, 42, and 43) and ‘high risk’ types (16, 18, 31, 33, 35, 39, 45, 51, 52, 56, 58, 59, 68, 69, 73, and 82). Most of the low risk HPV infections are asymptomatic and are not fatal, however infection to high risk HPV such as type 16 and 18 may cause cervical, anal, vaginal, vulvar and penile cancer (Centre of Disease Control, 2012). Low risk HPV generally cause warts on the skin surface which rarely develop into malignancy. Type 16 and 18 both were originally isolated from cervical carcinomas of human body. More than 70% of human cervical is due to the infection of either HPV 16 or 18. According to CDC, in 2008 it was estimated 11,070 cases of cervical cancer in United States and about 3,870 deaths due to cervical cancer. Higher percentage of HPV persistent infection occurs by HPV-16 and the risk of getting cervical cancer due the progression of disease is higher for HPV 16 and 18 and 45 (Tino F. Schwarz, 2008).

Human Papillomavirus (HPV) is a sexually transmitted virus that spreads from person to person by direct contact of infected tissue. According to the CDC, nearly all men and women will contract HPV at some point in their life (Centers for Disease Control and Prevention [CDC], 2013). HPV can cause cervical, vaginal and vulvar cancers in females. HPV can also cause anal, throat, and neck cancer in both males and females. HPV is also known to cause genital warts in both males and females. According to the National Cancer Institute (2013), “approximately 12,340 new cases of cervical cancer will be diagnosed in the US, and 4,030 US women will die

Cervical cancer has a major impact on women’s lives; it is the second most common cause of cancer-related diseases and death among women worldwide. According to the Center for Disease Control and Prevention (2010), cervical cancer is the cancer that forms in tissues of the cervix. The cervix is the lower, narrow end of the uterus that connects the vagina to the upper part of the uterus. Cervical cancer is a slow-growing cancer that may not cause any symptoms at first but may cause pelvic pain or bleeding from the vagina later. It is mostly caused by a human papillomavirus (HPV) infection. HPV is a common virus that is passed from one person to another during sexual activity (Center for Disease Control and Prevention [CDC], 2010).

One of the first signs of HPV came in Italy in 1842 when a doctor noticed that married women and prostitutes developed cervical cancer, but nuns did not. While the doctor did not successfully determine the cause, this research was one of the first signs that cancers could be sexually transmitted. In 1907 Giuseppe Ciuffo determined that skin warts and genital warts were related and the likely cause of both types of warts was a virus. This hypothesis was confirmed in 1949 when technology became available to observe the virus itself. The overall study of papillomaviruses took a large step forward in 1930 when Peyton Rous discovered that the viruses could cause skin cancer in rabbits. In 1976 Dr. Harald zur Hausen proposed that the HPV caused cervical

Cervical cancer is the second foremost occurring cancer in women after breast cancer. Cervical cancer is a sexually transmitted disease caused by the human papillomavirus, or HPV. Infection by HPV typically occurs in the early years of sexual activity according to the World Health Organization (WHO), but it can take up to a full twenty years for it to develop into a full-blown malignant tumor. Scientists believe that for all intents and purposes all cervical cancer cases are caused by infection with a few types of cancer. Great strides have been made in recent years in the development of a vaccine to treat the cervical cancer. Scientists have cultivated a prophylactic vaccine that would protect against the human papillomavirus. HPV's

Human papillomavirus (HPV) is the most prevalent virus in the human population. Almost all people will be exposed to HPV infections in their lifetime. HPV-associated cancers comprise 5% of all human cancers. Two prophylactic vaccines that are designed to block the four most prevalent HPV types (>150 types) in the genital infection have reduced the incidence in the vaccinated population. However, the vaccines offer no therapeutic effect against pre-existing infections. Furthermore, the vaccination completion rate was 26 % overall. The large unvaccinated population will continue to be at the risk of developing HPV-associated diseases and cancers until an effective treatment is available.

The Human Papilloma Virus, in short terms known as HPV, is a sexually transmitted infection that can potentially lead to cervical cancer and genital warts. All cases of HPV do not cause cervical cancer, only certain strains. Yet, the rising number of deaths from cervical cancer actually caused by HPV has undeniably caught the attention of the public. In response to the cervical cancer death rate, pharmaceutical companies have developed an HPV vaccine. The vaccine was considered a major medicinal breakthrough for some, but raised a number of concerns for others. Although the safety along with the effectiveness of the vaccine has been proven, it continues to originate controversy as both advocates and opponents assess their views of whether

Human Papillomavirus is a broad term used to describe over one hundred and fifty related viruses. The Human Papillomavirus, better known as HPV is named for the warts (papillomas) that become present on the skin of an HPV victim. HPV is transmitted via intamainte skin-to-skin contact. Each year a small number of cases of HPV go unknown because no symptoms are present or the body fights away the virus. Other cases that do not go away commonly are expressed in genital warts and cancers. Some cancers commonly developed from HPV are cervical, vaginal, anus, back of the throat, tonsil and tongue cancers (What). In recent years researchers,

Human Papillomavirus is a part of the papillomaviridae family and it’s named for papillomas (warts) produced by polyoma (tumors), and vacuolation (cytoplasmic vacuoles

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’

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.
