What You Need to Know about Cervical Cancer

Thursday, February 6th, 2014

Cervical cancer, just as the name implies, forms in the tissues of the cervix, which connects the vagina and the uterus. Generally slow growing, cervical cancer usually does not cause any symptoms. This makes it extremely important to get regular pelvic exams, during which screening tests are done that can find early-stage cervical cancers and even precancerous cells.

Any women can get cervical cancer, but it is typically found in women over 35. There are about 12,000 new cases diagnosed in the United States each year. Almost all cervical cancers are caused by HPV (human papilloma virus), the virus that causes genital warts.

Who Is at Risk?

There are several risk factors that increase a woman’s chances of developing cervical cancer. If you have none of these risk factors, your odds of getting it are very low. These risks include HPV infection (which you may not be aware of, another reason why those pelvic exams are so important); smoking or exposure to secondhand smoke; HIV infection, which can significantly weaken the immune system; certain medications which weaken immune system response; and multiple sexual partners.   

Can Cervical Cancer Be Prevented?

The good news is that cervical cancer is highly preventable. The first step for younger women and girls is to get vaccinated against HPV. Gardasil, a vaccine that prevents HPV infection, protects against the four types of HPV that are responsible for most cervical cancers as well as genital warts (70% and 90% respectively). The vaccine is administered via a series of three simple injections and has very few and mild side effects.

An annual visit to your gynecologist is another excellent way to be sure that, should cervical cancer be present, it is caught in its early and easily treatable stage. It is important for women to realize that even if they haven’t been sexually active recently, they are still at risk for cervical cancer if they have ever had sex. For this reason, continued screening is vital and saves numerous lives every year.

Keep in mind that anyone can lower their risk of various types of cancers by living a healthful lifestyle. Eating plenty of fruits and vegetables, getting enough exercise and enough sleep, and avoiding smoking and other dangerous chemicals are all effective ways to protect yourself and your family.

While cancer cannot always be prevented, it can often be found early and treated. If you haven’t seen your gynecologist recently and it’s closing in on a year (or has been longer than that), make an appointment today. Ignorance is not bliss when it comes to cancer – it’s often a death sentence.

Cancer Deaths Down; More Progress Still Needed

Monday, February 3rd, 2014

Great news: the death rate from cancer is falling. Over the past 20 years, cancer deaths have decreased dramatically and steadily. After peaking in 1991, deaths from cancer have fallen 20%. That’s well over a million deaths prevented over 20 years!

The American Cancer Society’s research shows progress – for example, middle-aged black men are the group with the largest decline in cancer deaths – but also the need for continued research and improvements in care, as cancer deaths are still more common in black men than in white men. Experts estimate that there will be over 1.5 million new cases of cancer in the US in 2014, about 586,000 of which will result in death.

The divide in cancer cases and deaths between races and ethnicities is starkly evident when one considers that even though the rate of deaths has been effectively cut by half in middle-aged black men, their deaths from cancer are still significantly more common than those of white men. The lowest rate of cancer deaths is seen in Asian Americans. Even more deaths could be prevented if the knowledge we now have about fighting cancer were applied across all groups of people – including the poorest subset of the population.

Lung cancer continues to top the list of fatal cancers, along with breast, colon, and prostate cancers. These four cancers alone are responsible for almost half of all cancer deaths in the US, with lung cancer causing more than a quarter of cancer deaths. Researchers estimate that this year, these four cancers will be the most common cancers diagnosed.

Still, the rates of not only deaths but new cases of cancer are also falling. One reason is that more people are having regular colonoscopies, during which pre-cancerous polyps can be removed and full-blown cancer avoided. Lung cancer occurrence has also decreased, thanks in large part to declining numbers of smokers.

Doing Your Part

The number of new cancer cases as well as the number of deaths from cancer can be further reduced by individuals taking a proactive approach to preventing cancer – or catching it early. This is one reason why your annual appointment with your gynecologist is so important; cervical and other cancers can be detected and treated in the early stages, before metastasis complicates your prognosis. Screening for other types of cancers, such as breast cancer and colorectal cancer, is also highly effective at detecting cancer early on. Most cancers are highly treatable when caught early. Free and low-cost cancer screenings are available in many states.

You can further reduce your cancer risk by getting an HPV vaccine and/or a hepatitis B vaccine; ask your doctor if these are right for you. Besides getting regular preventive medical care, avoiding tobacco, limiting sun exposure and avoiding tanning beds, keeping alcohol use to a minimum, getting plenty of exercise, and eating lots of fruits and vegetables can all go a long way toward helping your prevent – and fight – cancer.
