Understanding Cervical Cancer: Unraveling Risk Factors and Prevention Strategies

-



 Cervical cancer, a formidable health challenge, continues to be a leading malignancy in developing countries, including India. In the United States, it ranks as the third most common gynecological neoplasm, following uterine and ovarian cancers. However, in developing nations where healthcare resources are limited, cervical cancer stands as the second most common cause of cancer deaths in women. In this blog, we will explore the risk factors associated with cervical cancer and delve into effective prevention strategies, considering the significant impact it has on women's health worldwide.

The Landscape of Cervical Cancer

Cervical cancer is unique in its potential for prevention due to its long pre-invasive state, the availability of cervical cytology screening programs, and the effectiveness of treating preinvasive lesions. With a mean age of 47 years, cervical cancer cases exhibit a bimodal distribution, peaking at 35-39 years and 60-64 years of age. Squamous cell carcinomas, the most common type, typically arise from the squamocolumnar junction of the cervix, preceded by precancerous stages such as CIN I, CIN II, and CIN III.

Cervical Cancer Risk Factors

Understanding the risk factors associated with cervical cancer is crucial for early detection and prevention. These factors include:

  • Infection with High-risk HPV (16,18,31,33): Human Papillomavirus (HPV) infection, particularly with high-risk strains, is a significant risk factor for cervical cancer.

  • Infection with HSV, Chlamydia: Infections such as Herpes Simplex Virus (HSV) and Chlamydia have been linked to an increased risk of cervical cancer.

  • Young Age at First Intercourse: Early initiation of sexual activity is associated with an elevated risk of cervical cancer.

  • Multiple Sexual Partners: Having multiple sexual partners increases the likelihood of exposure to HPV and other sexually transmitted infections.

  • High Parity: Women with multiple pregnancies, known as high parity, face an elevated risk of cervical cancer.

  • Low Socioeconomic Status: Limited access to healthcare and resources, often associated with low socioeconomic status, contributes to the prevalence of cervical cancer.

  • Immunosuppressed Individuals: Individuals with compromised immune systems, whether due to medical conditions or immunosuppressive treatments, are at an increased risk.

  • Smoking: Tobacco use, specifically smoking, is a well-established risk factor for cervical cancer.

  • Dietary Deficiency of VIT-C, E, and Folic Acid: A diet lacking essential vitamins like C and E and folic acid deficiency can contribute to increased susceptibility.

Screening Methods for Cervical Carcinoma

Early detection is key to successful cervical cancer management. Screening methods include:

  • PAP Smear (Conventional/LBC): The PAP smear is a widely used screening method involving examining cervical cells for abnormalities.

  • Visual Inspection with Acetic Acid (VIA): VIA is a visual examination of the cervix with acetic acid to detect precancerous lesions.

  • Visual Inspection with Lugol's Iodine (VILI): VILI involves applying Lugol's iodine to identify abnormal areas on the cervix.

  • HPV Testing: Testing for the presence of HPV, especially high-risk strains, is a crucial component of cervical cancer screening.

Prevention of Cervical Cancer

Preventing cervical cancer involves a multi-faceted approach, including vaccination and behavioural interventions:

  • HPV Vaccines: HPV vaccines, including Cervarix, Gardasil, and Gardasil9, have effectively prevented persistent infections.

  • Vaccine Schedule: Ideally administered to girls aged 9-13 years, the vaccine schedule varies based on age, with a two-dose regimen for those under 15 years and a three-dose regimen for those over 15 years.

  • Prevention of HPV Infection: Behavioral interventions, such as delaying sexual activity until cervical epithelium maturity, limiting sexual partners, maintaining hygiene, and quitting smoking, play a crucial role in preventing HPV infection.

Final Thoughts

As we dissect the intricacies of cervical cancer, it becomes evident that a comprehensive and proactive approach is essential. From understanding risk factors to embracing prevention strategies, the fight against cervical cancer requires a collective effort from healthcare providers, policymakers, and individuals. The advancements in vaccination, coupled with targeted screening methods, offer a beacon of hope in the battle against this formidable disease. Let us continue to prioritize awareness, education, and accessible healthcare to empower women in safeguarding their well-being.

Remember, knowledge is a powerful tool in the realm of healthcare, and the more we understand about cervical cancer, the better equipped we are to prevent its impact on women's lives.

WOMEN AND POST MARITAL DEPRESSION.

-
 Post-marriage depression is sometimes ignored in favour of an "adjustment phase." This absolves the problem of significance and proper consideration. Depression after marriage does exist. It goes beyond the post-wedding blues and mood fluctuations that a married lady experiences.  Persistent violence can make a woman feel alone, resentful of social interactions with her family and the wider world, and permanently anxious and panicked. Because it is typically referred to as an "adjustment phase," and since the woman is almost always the one doing the "adjusting," this violence never ends. When the woman decides to remain silent in the face of violence, the situation becomes even worse. The idea that a daughter-in-law is a "bearer of a family's pride" and "as calm and decent as a cow" makes violence 'normal' and then either kept a secret between the couple or among the family. The sanctions that a woman's parents and in-l...
