Linking HPV to Cervical Cancer in Women:What you Should Know Right Now

Cancer is a complex condition characterized by the uncontrolled growth of cells within the body. It is crucial to note that cancer is named according to its initial point of origin, regardless of whether it subsequently spreads to other areas. One such example is cervical cancer, a specific type of malignancy that develops in the cells of the cervix—the lower part of the uterus that connects to the vagina. Ordinarily, when the human papillomavirus (HPV) enters the body, the immune system effectively combats it, preventing any harm. Nonetheless, in a small percentage of individuals, the virus manages to persist for an extended period, contributing to the development of abnormal cervical cells and ultimately leading to cancerous transformation.

While multiple factors contribute to the development of cervical cancer, it is important to highlight the significant role played by various strains of the human papillomavirus (HPV), a sexually transmitted infection. In fact, HPV is the most prevalent sexually transmitted infection in the United States. The term "human papillomavirus" is derived from the presence of papillomas, commonly known as warts, which are a frequent manifestation of certain HPV infections. With over 100 distinct types, each HPV strain is assigned a specific number, denoted as the HPV type.

In both men and women, more than 40 HPV types can infect the genital areas, including the skin of the penis, vulva, and anus, as well as the linings of the vagina, cervix, and rectum. Furthermore, these HPV types can also infect the mucous membranes lining the mouth and throat.

HPV encompasses a diverse range of types, primarily classified into two main categories: Cutaneous HPV and Mucosal HPV. Cutaneous HPV specifically affects the skin, leading to the development of common warts, distinct from genital warts. On the other hand, Mucosal HPV targets cells residing in moist surfaces such as the vagina, cervix, vulva, anus, inner foreskin, and urethra of the penis. Furthermore, these types of HPV can also invade the inner linings of the nose, mouth, throat, windpipe or trachea, as well as the passageways to the lungs or bronchi. 

Over 40 mucosal HPV types can be transmitted through direct sexual contact, encompassing vaginal, anal, and oral sex.

The classification of Mucosal HPV is further subdivided into two primary types based on their potential to cause cancer: low-risk HPV and high-risk HPV. Low-risk HPV types do not give rise to cancer but can result in the formation of skin warts around the genital and anal areas. Notably, types 6 and 11 of HPV are responsible for approximately 90 percent of all cases of genital warts. Conversely, high-risk HPV has the potential to induce cancer. Among the identified high-risk types, approximately 12 are associated with the development of HPV-related cancers, with types 16 and 18 being the most prevalent culprits.

Contrary to popular belief, acquiring an HPV infection does not invariably lead to cancer. In fact, the majority of HPV strains do not cause any symptoms or complications at all. However, there are several strains, approximately a dozen, that possess the potential to progress to cancerous conditions. Notably, two specific HPV strains, namely types 16 and 18, account for 70 percent of all cases involving cervical cancer and precancerous cervical lesions. Furthermore, approximately 70 percent of head and neck cancers, particularly oropharyngeal cancers affecting areas such as the tonsils, soft palate, and base of the tongue, are linked to HPV.

Sexual transmission is the primary means through which HPV spreads, predominantly occurring via direct skin-to-skin contact during vaginal, anal, or oral intercourse with an individual carrying the virus. Importantly, it is worth noting that an individual infected with HPV can transmit the virus even in the absence of noticeable symptoms. It is crucial to understand that HPV is not transmitted through blood or other bodily fluids.

While not everyone experiences them, the most common manifestation of mucosal HPV infection is the presence of genital warts. It is important to highlight that the development of these warts typically takes some time, appearing weeks or even months after contact with a sexual partner who has HPV, but they can subsequently exhibit rapid growth.

In some cases, genital warts caused by HPV may be inconspicuous, causing minimal discomfort or no symptoms at all. However, in other instances, they can give rise to burning pain, itching, and various other uncomfortable sensations.

Initially, these warts appear as small, soft, moist growths with a pink or gray coloration. They have a tendency to grow rapidly and transform into rough, irregular bumps. Often, they manifest in clusters and exhibit a distinctive cauliflower-like appearance. It is worth noting that these warts can even develop in hidden areas, such as the cervix, urethra, or vulva, where they may go unnoticed, leading to a lack of awareness about their presence.

Ordinarily, the immune system is capable of clearing an HPV infection without intervention. However, persistent infections are the ones that can potentially result in cellular changes, which may, after several years, progress to cancerous conditions.

For women, an HPV test is typically conducted alongside a Pap smear, referred to as a co-test. During a pelvic exam, a sample of cells is collected from the cervix and subsequently sent to a pathologist for interpretation and analysis. This combined screening approach aids in the detection and monitoring of any potential HPV-related abnormalities or precancerous changes.

In the event of a positive HPV test or the identification of abnormal cells during a Pap smear that may indicate a potential risk of cervical cancer, your healthcare provider may opt for further testing or recommend a colposcopy. A colposcopy is a procedure that employs a magnifying lens and light to enable your doctor to examine the inside of your cervix with greater clarity. It is important to note that currently, there is no HPV test available for men.

In the United States, approximately 13,000 new cases of cervical cancer are diagnosed each year, and sadly, around 4,000 women lose their lives to this disease. According to the CDC, Hispanic women have the highest rates of developing cervical cancer, while Black women have the highest rates of mortality attributed to cervical cancer.

It is highly recommended to maintain regular visits to your gynecologist for comprehensive care. Stay informed about the risks of exposure you may encounter and take preventive measures to safeguard your health. Prevention is the crucial first and perhaps the easiest step in protecting your well-being.
