As recently as the s, cervical cancer was a major cause of death among women of childbearing age in the United States. However, with the introduction in . Cervical cancer used to be the leading cause of cancer death for women in the United States. However, in the past 40 years, the number of cases of cervical. Cervical cancer was once one of the most common causes of cancer death for American women. The cervical cancer death rate dropped.
a Death Leading Cancer Cervical of is Cause
Noncarcinoma malignancies which can rarely occur in the cervix include melanoma and lymphoma. For cases treated surgically, information obtained from the pathologist can be used in assigning a separate pathologic stage, but is not to replace the original clinical stage.
Cervical cancer is staged by the International Federation of Gynecology and Obstetrics FIGO staging system, which is based on clinical examination, rather than surgical findings. It allows only these diagnostic tests to be used in determining the stage: Checking the cervix by the Papanicolaou test Pap test , for cervical cancer has dramatically reduced the number of cases of and mortality from cervical cancer in developed countries. The treatment of low-grade lesions may adversely affect subsequent fertility and pregnancy.
Educational materials also help increase the likelihood women will go for screening, but they are not as effective as invitations. According to the European guidelines, the age at which to start screening ranges between 20 and 30 years of age, but preferentially not before age 25 or 30 years, and depends on burden of the disease in the population and the available resources.
In the United States, screening is recommended to begin at age 21, regardless of age at which a woman began having sex or other risk factors. There are a number of recommended options for screening those 30 to Screening is not beneficial in women older than 60 years if they have a history of negative results. Liquid-based cytology is another potential screening method.
The United States Preventive Services Task Force supports screening every 5 years in those who are between 30 and 65 years when cytology is used in combination with HPV testing. Pap tests have not been as effective in developing countries. Condoms may also be useful in treating potentially precancerous changes in the cervix. Exposure to semen appears to increase the risk of precancerous changes CIN 3 , and use of condoms helps to cause these changes to regress and helps clear HPV.
Abstinence also prevents HPV infection. HPV vaccines are typically given to age 9 to 26, as the vaccine is only effective if given before infection occurs. The vaccines have been shown to be effective for at least four  to six  years, and they are believed to be effective for longer;  however, the duration of effectiveness and whether a booster will be needed is unknown.
The high cost of this vaccine has been a cause for concern. Several countries have considered or are considering programs to fund HPV vaccination. Since , young women in Japan have been eligible to receive the cervical cancer vaccination for free. Vitamin A is associated with a lower risk  as are vitamin B12 , vitamin C , vitamin E , and beta-Carotene.
The treatment of cervical cancer varies worldwide, largely due to access to surgeons skilled in radical pelvic surgery, and the emergence of fertility-sparing therapy in developed nations. Because cervical cancers are radiosensitive, radiation may be used in all stages where surgical options do not exist.
Surgical intervention may have better outcomes than radiological approaches. Microinvasive cancer stage IA may be treated by hysterectomy removal of the whole uterus including part of the vagina.
Alternatives include local surgical procedures such as a loop electrical excision procedure or cone biopsy. If a cone biopsy does not produce clear margins  findings on biopsy showing that the tumor is surrounded by cancer free tissue, suggesting all of the tumor is removed , one more possible treatment option for women who want to preserve their fertility is a trachelectomy. It is a viable option for those in stage I cervical cancer which has not spread; however, it is not yet considered a standard of care,  as few doctors are skilled in this procedure.
Even the most experienced surgeon cannot promise that a trachelectomy can be performed until after surgical microscopic examination, as the extent of the spread of cancer is unknown. If the surgeon is not able to microscopically confirm clear margins of cervical tissue once the woman is under general anesthesia in the operating room, a hysterectomy may still be needed.
This can only be done during the same operation if the woman has given prior consent. Due to the possible risk of cancer spread to the lymph nodes in stage 1b cancers and some stage 1a cancers, the surgeon may also need to remove some lymph nodes from around the uterus for pathologic evaluation.
A radical trachelectomy can be performed abdominally  or vaginally  and opinions are conflicting as to which is better. Complications are uncommon, although women who are able to conceive after surgery are susceptible to preterm labor and possible late miscarriage.
Radiation therapy is given as external beam radiotherapy to the pelvis and brachytherapy internal radiation. Women treated with surgery who have high-risk features found on pathologic examination are given radiation therapy with or without chemotherapy to reduce the risk of relapse.
When cisplatin is present, it is thought to be the most active single agent in periodic diseases. On June 15, , the US Food and Drug Administration approved the use of a combination of two chemotherapy drugs, hycamtin and cisplatin, for women with late-stage IVB cervical cancer treatment. For surgery to be curative, the entire cancer must be removed with no cancer found at the margins of the removed tissue on examination under a microscope.
Prognosis depends on the stage of the cancer. These statistics may be improved when applied to women newly diagnosed, bearing in mind that these outcomes may be partly based on the state of treatment five years ago when the women studied were first diagnosed.
Regular screening has meant that precancerous changes and early-stage cervical cancers have been detected and treated early.
Figures suggest that cervical screening is saving 5, lives each year in the UK by preventing cervical cancer. All of the Nordic countries have cervical cancer-screening programs in place. In Africa outcomes are often worse as diagnosis is frequently at a latter stage of disease. Worldwide, cervical cancer is both the fourth-most common cause of cancer and deaths from cancer in women. Australia had cases of cervical cancer in The number of women diagnosed with cervical cancer has dropped on average by 4.
In Canada, an estimated 1, women will have been diagnosed with cervical cancer in and will have died. In India, the number of people with cervical cancer is rising, but overall the age-adjusted rates are decreasing. In the European Union, about 34, new cases per year and over 16, deaths due to cervical cancer occurred in An estimated 12, new cervical cancers and 4, cervical cancer deaths will occur in the United States in The median age at diagnosis is Hispanic women are significantly more likely to be diagnosed with cervical cancer than the general population.
The rates of new cases in the United States was 7 per , women in Epidemiologists working in the early 20th century noted that cervical cancer behaved like a sexually transmitted disease. These historical observations suggested that cervical cancer could be caused by a sexually transmitted agent.
Initial research in the s and s attributed cervical cancer to smegma e. In summary, HSV was seen as a likely cause because it is known to survive in the female reproductive tract, to be transmitted sexually in a way compatible with known risk factors, such as promiscuity and low socioeconomic status.
HSV was recovered from cervical tumour cells. In Australia, Aboriginal women are more than five times more likely to die from cervical cancer than non-Aboriginal women, suggesting that Aboriginal women are less likely to have regular Pap tests. After controlling for stage, there still existed differences in survival rates. From Wikipedia, the free encyclopedia.

Abramson Cancer Center of the University of Pennsylvania. Cochrane Database Syst Rev 5: Archived PDF from the original on 1 February Retrieved 8 November Most countries in the region offer Pap screening but they lack prevention programs and do not offer follow-up or treatment in cervical cancer cases detected by the smear.
Overall, 63 percent of women in the region have had a Pap smear at least once, but there are great differences across countries. While 70 percent of women in Brazil and Costa Rica have had at least one Pap smear, only 35 percent of women in Nicaragua have had at least one test. The vast majority of these women have been screened during their reproductive life, at young ages when the risk of precancerous lesions is lower.
It is important to note that one Pap test alone is essentially useless; women need to obtain regular Pap tests. Women from lower socioeconomic status and those with less education are less likely to know of the Pap test. Furthermore, women with the least education are more likely to be diagnosed with later stages of cervical cancer.
In most instances, they do not have the financial resources to obtain treatment. Whatever the screening test used, a fundamental problem in the region is the follow-up of screened women and the provision of diagnosis and treatment for cancer cases detected during the screening. A recent study in Peru showed that only 20 percent of women who had a Pap smear that identified a precancerous lesion received a diagnosis and follow-up treatment.
There are effective alternatives to Pap tests and efforts to use HPV testing to identify women at high risk for cervical cancer. Researchers are also working to produce a viable vaccine against one or two types of HPV. There are also simple and inexpensive techniques to treat precancerous lesions, like cryotherapy, that can be applied in primary care clinics throughout Latin America and the Caribbean, thus reducing much potential suffering for affected women. They told me what I had, and I started crying, for blocks and blocks, as if someone had died within me.
People were looking at me and my little girl; I was looking at the trees, as though I had never seen them in my entire life. I thought that tomorrow I was going to be dead, and who would care for my children. Countries with low and medium low economic status, however, exhibit higher mortality levels. Among the sub-regions, Central America has the highest incidence and mortality rates.
According to PAHO, trends in the region suggest that mortality due to cervical cancer did not decline between and but remained fairly constant five to six deaths per , women. Three countries — Chile, Costa Rica, and Mexico — have recorded changes over time, but not always for the better. For instance, in Costa Rica, there was a reduction in mortality from to ; however, this may be due to improved coverage and accuracy in the certification of deaths rather than due to real reductions.
Chile realized a decline in mortality from cervical cancer among women under 35, but not among older women, who represent the majority of cases. In Mexico, on the other hand, there appears to have been an increase in deaths from cervical cancer, but this may be due to better certification of deaths.
Cervical cancer is a disease that largely affects middle-aged and elderly women. Sixty percent of this type of cancer occurs in women between 35 and 60 who are in the prime of life and important supporters of their families. Unlike many cancers, cervical cancer can be prevented. The first step is to educate women about how to protect themselves against HPV, a common sexually transmitted infection STI that can cause cervical cancer.
Other important factors associated with the disease include tobacco use, number of sexual partners for either the woman or her partner , early age at first intercourse, and early age at first birth.
Women typically become infected with HPV during their teen years and in their twenties or thirties. However, it may take 20 or more years for cervical cancer to develop after the initial infection. Cervical cancer develops slowly from precancerous lesions dysplasia.
There are typically three stages: Seventy percent of low-grade dysplasia disappears over time and does not require treatment. High-grade dysplasia, which will progress to cancer within 10 years if left untreated, requires both treatment and regular monitoring.
Invasive cancer, if not treated with surgery and radiation therapy, is always fatal. Primary prevention, which includes a focus on using condoms or other barrier methods and engaging in mutually monogamous sexual relationships, help prevent cervical cancer, but it is unclear how these strategies affect the overall incidence of the disease. It is easily transmitted, asymptomatic, and the virus can remain in the body for years. Furthermore, HPV can occur in the genital and anal parts of the body, including areas not covered by male condoms.
Secondary prevention strategies such as inexpensive screening, treatment, and follow-up have been highly effective in reducing the incidence of cervical cancer. To date, prevention efforts have focused on using the Pap smear to screen at-risk women and then treating the pre-cancerous lesions by removing the diseased tissue. In situations where screening quality and coverage is high, this procedure has significantly reduced the incidence of cervical cancer.
In Latin America and the Caribbean, an estimated 63 percent of women have had a Pap smear. There is, however, great variability in coverage across countries. For example, PAHO survey data suggest that only 35 percent of women in Nicaragua have had a Pap smear at least once, compared with 70 percent in both Brazil and Costa Rica. In Haiti, there is no national screening policy for cervical cancer, and there are only a small number of cytologists throughout the country.
Other factors such as age, education, income, and residence contribute to large differences in Pap smear coverage across the region. For instance, according to PAHO, in Brazil, Chile, and Mexico, women from lower socioeconomic status are less likely than their better-off counterparts to know of the Pap test or to have undergone a test.
In addition, in some countries such as Ecuador, the incidence of cervical cancer is almost twice as high among women with no education or only primary education when compared to those with secondary or higher education. And women with the least education are more likely to be diagnosed with later stages of cervical cancer stages III or IV whereas women with higher education have their cancers detected earlier.
When implemented properly, screening can be an effective intervention for cervical cancer. According to the IARC, screening once every three years can produce a 91 percent reduction in lifetime incidence of the disease, while an interval of five years confers an 84 percent benefit.
In addition to being easy and effective, screening and treatment of precancerous lesions is cost-effective when compared with expensive hospital-based treatment of invasive cancer. While screening and treatment programs have been highly successful in reducing deaths from cervical cancer in more developed countries, they have not been applied successfully in Latin America and the Caribbean.
