Treatments for genital warts
Among the most common sexually transmitted infections (STIs) are genital warts caused by the human papillomavirus (HPV). The virus is easily transmitted through skin-to-skin contact during sexual activity. Genital warts usually occur on the vulva or cervix and can spread to other parts of the body. Although genital warts are usually benign, they can cause pain and discomfort during sexual activity.
There are several types of treatments available for genital warts. Some of the options include medications, topical agents, and surgery. Each treatment should be determined by your doctor. The final decision will depend on how extensive your warts are and the extent of your symptoms. It is also important to weigh the negative effects of any treatment. For instance, surgery may be necessary if you have recalcitrant warts that haven’t responded to other treatments.
The medications most commonly used to treat genital warts are imiquimod, podophyllotoxin, and Bichloracetic acid. The medications are applied directly to warts or used in conjunction with a local anesthetic. They may be applied at home or at your doctor’s office. They can be painful, but they may also be effective in reducing the severity of symptoms.
These medications can be applied directly to warts, and they may cause some side effects, such as rashes, blisters, and pain. Some medications can also cause damage to the surrounding skin. If you are pregnant, you should talk to your doctor before using any medication. You may also need to use contraception during treatment. You may also be able to get rid of your warts at home by using a special device called a cryoprobe.
There are also older treatments, such as podophyllin, that are still used to treat recalcitrant warts. Podophyllin is a plant-based resin that works by stimulating the immune system. Podophyllin is applied directly to warts, and it is a less painful option. However, you should be careful about using it during pregnancy, because it can weaken latex barrier devices.
Another option is laser treatment. Laser treatments are used for larger warts that are hard to remove, and they can cause scarring and pain. However, they can be expensive and are often reserved for very difficult warts. They can also cause side effects such as pain, swelling, and blisters.
Pap tests are also used to detect cervical changes due to genital warts. This test collects a small sample of the cervix and examines the cells using a microscope. The results of a Pap test are usually abnormal, and it may be necessary to have more frequent Pap smears. These tests can also detect early signs of cervical cancer.
You can also try home remedies for genital warts. These remedies are often touted as effective but have very little scientific evidence to support them. Some of the home remedies, such as using liquid nitrogen, may cause pain and swelling. If you use a liquid nitrogen treatment, you should not apply it to moist areas of the body, such as the vagina or anal area. It may also cause a burning sensation.
Cervical cancer
Papillomavirus (HPV) is a human viral infection that causes cancers of the reproductive tract, most commonly cervical cancer. HPV is most commonly spread through sexual contact. The virus infects the cervix, vagina, and anus. Some HPV types also cause warts. Most HPV infections are clear on their own, but some types can be persistent and lead to cancer. Some types of HPV are highly associated with cervical squamous cell carcinoma. Others rarely lead to cancer.
HPV infection is most commonly found in sexually active young women between 18 and 30 years of age. Women who have a history of cervical cancer or HIV are at increased risk of infection. HPV types 16 and 18 are the most common HPV types associated with cervical cancer. Other types, such as HPV-6, rarely lead to cancer. HPV type E6 and E7 gene products help distinguish high-risk HPV types from low-risk types. A nine-valent HPV vaccine protects against five additional high-risk HPV types. HPV vaccination is safe and effective. Vaccines are licensed in the US and approved by WHO.
Cervical cancer is the third most common cancer in women in the United States. It is estimated that about 604 thousand new cases will be diagnosed in 2020. The incidence of cervical cancer has been decreasing, in part because of widespread screening programs. However, cervical cancer still remains an important health concern worldwide. A global strategy for eliminating cervical cancer was adopted by the World Health Assembly in 2020. The strategy recommends a comprehensive approach to cervical cancer prevention that includes vaccination, screening, and interventions across the life course.
Most cervical cancers develop in the squamocolumnar junction, the junction between the squamous epithelial cells of the ectocervix and the columnar epithelial cells of the endocervix. Infections with HPV type 16 and 18 are associated with 70% of cervical cancers. In addition, HPV types 8 and 19 are also associated with cervical cancer.
The World Health Assembly defined the global strategy for eliminating cervical cancer as having less than four cases per 100,000 women per year. It also set 90-70-90 targets for reducing the incidence of cervical cancer in low- and middle-income countries. The strategy recommends interventions across the life course, with cervical cancer prevention and detection of high-risk lesions as primary goals. It also recommends a comprehensive approach to cervical cancer screening, including vaccination, community education, and surgical intervention.
The World Health Assembly defines HPV as a major cause of cervical cancer. It also suggests that HPV-independent tumors have worse oncologic outcomes. HPV-independent cervical cancers are associated with lower DNA methylation levels, lower expression of genes involved in inflammatory processes, and lower APOBEC mutagenesis signatures. HPV-independent cervical cancers also have higher epithelial-mesenchymal transition mRNA scores and lower p53 signaling. HPV-independent tumors are also more likely to have lymph node involvement in the early stages of the disease.
Some investigators have suggested that CIN2 is the true precursor of cervical cancer. However, HPV-independent cervical cancers are characterized by the lack of CDKN2A gene mutations. These tumors have lower expression of inflammatory genes and tend to use alternative pathways to maintain tumor growth. HPV-independent tumors also exhibit lower activation of NF-kb and KRAS.
