How Often Do I Need a Pap Test?

Posted on by

Almost 80 years ago, Dr. George Papanicolaou developed a simple test, the Pap test (also called the Pap smear), done in a doctor’s office to check for cervical cancer. During a pelvic exam, a doctor swabs a small sample of cervical tissue and looks for abnormal cells. If these precancerous cells are detected, it will lead to more tests or other more invasive treatments such as a colposcopy (in which actual tissue may be removed). In the 1930s, when Papanicolaou was developing his test, cervical cancer was more lethal than breast cancer. But since the development of this test, the number of women dying from cervical cancer has dropped dramatically. In 2009, of the 4,000 women in the United States who died of cervical cancer, most had never been screened or had not been screened in the 10 years before their diagnosis.

This year, the U.S. Preventive Services Task Force recommended less frequent Pap testing.

Cervical cancer is most common in women between ages 35 and 55, and usually develops from a human papillomavirus or HPV infection. Not all HPV infections lead to cervical cancer, and it can take decades for a persistent infection with a high-risk type of HPV to become cancer. High-risk HPV types are sexually transmitted and can lead to cervical cancer and also anal, penile, and oral cancers.

There are two types of screening: Pap tests and HPV tests. While they both require a pelvic exam in which cells are taken from the cervix, Pap tests look for abnormal or precancerous cells, and HPV tests look for DNA or RNA from high-risk HPV types in cervical cells. Both tests are used to try to catch cervical cancer in its earliest stages so that it can be successfully treated. Continue reading →

Welcome to the latest installment of “Over 90 Percent of What Planned Parenthood Does,” a series on Planned Parenthood Advocates of Arizona’s blog that highlights Planned Parenthood’s diverse array of services — the ones Jon Kyl doesn’t know about.

Pap tests are not beloved — there, I said it. Many people who receive them hope for the day that medical science devises an equally effective but noninvasive test, whatever that might entail, as they may find them to be anything from slightly awkward to incredibly traumatizing. However, the evidence overwhelmingly shows that access to Pap testing (also called Pap smears) has transformed cervical cancer from a top killer into something that can be caught early and treated before it can do much damage. As a tool to reduce cancer deaths, Pap tests have been a resounding success.

In countries with widespread access to Pap tests, cervical cancer rates have plummeted.

A Pap test involves an instrument called a speculum being placed into the vagina to hold it open while a health care provider uses a small spatula or a tiny brush to collect cells from the cervix, which is at the opening of the uterus. These cells are analyzed in a laboratory, where a technician can determine if they are precancerous. (Cervical cancer is caused by a sexually transmitted virus called human papillomavirus, or HPV.) When caught in its precancerous stages, cervical cancer can be treated with procedures such as colposcopy and cryotherapy.

Pap testing guidelines have recently changed. Continue reading →

Over 90 Percent of What Planned Parenthood Does, Part 6: Vaccinations

Welcome to the latest installment of “Over 90 Percent of What Planned Parenthood Does,” a series on Planned Parenthood Advocates of Arizona’s blog that highlights Planned Parenthood’s diverse array of services — the ones Jon Kyl doesn’t know about.

You know what they say: An ounce of prevention is worth a pound of cure. Public health experts agree that vaccines are one of the most important advancements in medicine, and are incredibly safe and effective in preventing infectious disease. Many infectious diseases that used to lay waste to their victims are now unknown to many of us in the developed world — polio, whooping cough, measles, and rabies struck fear in the hearts of our forebears, but most young people today barely know what they are (although low rates of vaccination can still lead to outbreaks, such as 2008’s measles outbreak in Tucson). Smallpox, once a terrifying scourge, has been wiped off the planet thanks to vaccination campaigns.

We offer vaccinations against hepatitis A and B, as well as HPV.

Vaccines work by introducing antigens to your immune system. An antigen is a substance, such as a protein on the surface of a virus, that the immune system can recognize as dangerous. It is then able to attack the pathogen and, often, create a “memory” of that pathogen so it can attack it in the event of reinfection. The antigens in vaccines are very safe, and can be derived from many sources, such as inactivated (dead) or attenuated (weakened) pathogens, or fragments of pathogens. Some vaccines, such as those protecting against human papillomavirus and hepatitis B, are made with laboratory-synthesized fragments of the surface proteins of viruses, which are sufficient to produce immune response despite being completely noninfectious.

Planned Parenthood Arizona offers vaccinations against hepatitis A, hepatitis B, and human papillomavirus (HPV). All three of these viruses can be transmitted sexually, and hepatitis B and HPV can cause cancer if the infections become chronic. The hepatitis vaccines have led to all-time lows in rates of hepatitis A and hepatitis B; the HPV vaccine is still new, but emerging evidence suggests a possible decrease in HPV rates as herd immunity grows. Vaccination doesn’t just benefit you and your partner(s) — it benefits society as a whole. Continue reading →

Mobile Mammography Clinic: August 18 in Phoenix

According to Planned Parenthood’s information on screening, breast cancer is the second “most common type of cancer in American women. About 225,000 women will be diagnosed with breast cancer this year in the U.S. and 40,000 women will die from it.”

On August 18, free mammograms will be available in Phoenix.

Among the best screening tools for breast cancer is the mammogram, or X-ray of the breast. During a mammogram, the breast tissue is compressed between two plates and X-rayed. Those images are later checked for abnormalities. While this may not sound like fun, the entire procedure for a mammogram takes only about 20 minutes — and the actual compression, only a few seconds. Moreover, regular screening is a person’s best chance for early diagnosis.

Both the American Cancer Society and Planned Parenthood recommend annual mammograms starting at age 40. However, not everyone receives the recommended screenings, for various reasons. Some people may not know they fit the criteria for screening or may be confused by different organizations’ conflicting recommendations. (For instance, the U.S. Preventive Services Task Force recommends that annual screenings begin at age 50 rather than 40.) Others may find the procedure physically or emotionally uncomfortable. Still others, particularly in times of economic distress, may lack access to providers or the means to pay for such screenings. Continue reading →

World Hepatitis Day: The History of the Hepatitis B Vaccine

In the early 1970s, Ted Slavin, a hemophiliac, learned his blood was special. Over a lifetime of transfusions, he had slowly amassed a huge collection of antibodies, which are proteins produced by the immune system that attach to invaders, such as viruses and bacteria. When he started receiving transfusions in the 1950s, blood wasn’t screened for diseases, which meant that he’d been repeatedly exposed to some pathogens. His immune system manufactured large amounts of protective antibodies to battle these constant invaders, one of which was hepatitis B virus (HBV) — resulting in blood with extremely high concentrations of hepatitis B antibodies.

After sunshine and smoking, hepatitis B is the most common cause of cancer.

His physician relayed this discovery to Slavin — most doctors wouldn’t have bothered, and in fact might have surreptitiously sold his blood to researchers. Back then, scientists were at work on a hepatitis B vaccine, and hepatitis B antibodies were a hot commodity. Likewise, Slavin needed money — his medical condition precluded regular work, and treatments were costly. He contracted with labs and pharmaceutical companies to sell his antibodies directly, for as much as $10 per milliliter and up to 500 milliliters per order.

When someone has a chronic HBV infection, the virus has “hijacked” some of his or her cells, “tricking” them into manufacturing copies of the virus. A virus consists of an outer protein shell housing genetic information — the blueprint that cells follow when they produce virus copies. When hepatitis B viruses are manufactured in cells, an excess of surface proteins is produced — these waste products litter the bloodstream, and testing for their presence allows people to be diagnosed with HBV infections. These surface proteins are called antigens — and as luck (or evolution) would have it, the antibodies our immune systems produce can attach to viral antigens, helping us to keep pathogens at bay.

STD Awareness: HPV in Males

Human papillomavirus, or HPV, can affect both males and females.

Human papillomavirus, or HPV, affects people of all genders.

Whether it’s worries over Gardasil making girls go wild, or it’s somber discussion about cervical cancer, discourse about human papillomavirus (HPV) centers around its impact on females. But who are most of these females getting HPV from? For the most part, they’re getting it from male partners. And despite the fact that cervical cancer is the most common cancer associated with HPV, it is not the only one. A high-risk strain of HPV can lead to cancers of the penis, anus, mouth, and throat; additionally, there are strains of HPV that cause genital warts, which affect males and females equally. So why don’t males figure very prominently in discussions of HPV and the preventive vaccine, Gardasil?

Mouth, throat, penile, and anal cancers can all be caused by HPV.

Some people think that if they remain abstinent until marriage, they will be able to avoid sexually transmitted diseases (STDs) – but not very many people can say with certainty that their spouses have never had any other sexual partners. Eva Perón, the second wife of Argentine president Juan Perón and a leader in her own right, was made famous here by the musical Evita. According to physician and writer Shobha S. Krishnan, she died in 1952 of cervical cancer – the same fate that befell her husband’s first wife. Many believe that Juan Perón was the source of both women’s ultimately fatal HPV infections.

While one’s own sexual behavior can increase risk for acquiring an STD, it is not the only factor – the sexual history of one’s partner also plays an important role. HPV is especially tricky because there is currently no FDA-approved test for HPV in males – despite the fact that more than half of sexually active males are estimated to have been infected with HPV at some point in their lives. And, because it is so often asymptomatic, a male can carry this virus without knowing it, unwittingly infecting his partners. Continue reading →
