Does the HPV Vaccine Prevent Cervical Cancer? The Science Explained
What is HPV? Understanding the Virus Behind Cervical Cancer
Human Papillomavirus (HPV) is a group of more than 200 related viruses that can affect the skin and mucous membranes. Certain types of HPV are classified as high-risk because they are known to cause cancers, including cervical cancer. In fact, almost all cases of cervical cancer are caused by persistent infection with high-risk HPV strains, particularly HPV types 16 and 18. These viruses can invade the cells of the cervix, leading to mutations and potentially progressing into cancer if left untreated.
HPV is highly common, and most sexually active individuals will contract the virus at some point in their lives. However, in many cases, the body clears the virus on its own. When the infection does not resolve, it can lead to precancerous changes in cervical cells, which can develop into cancer over time.
The Link Between HPV and Cervical Cancer
HPV infection is the primary cause of cervical cancer, a leading cancer in women globally. When the virus persists in the cervical cells, it can cause changes that lead to dysplasia, a condition where the cells begin to grow abnormally. Over time, these abnormal cells may develop into cervical cancer if not detected early.
This is why regular screening through Pap smears and HPV tests is crucial. However, prevention through vaccination offers an even more effective way to reduce the risk of cervical cancer. The HPV vaccine helps protect against the strains that cause most cases of cervical cancer, potentially preventing the cancer before it can develop.
At Second Spring Women’s Clinic, our expert team emphasizes the importance of both HPV vaccination and regular cervical cancer screenings to ensure optimal prevention and early detection.
