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.
