Human papillomavirus (HPV) primarily damages epithelial tissues and mucous membranes, potentially leading to cancers in the cervix, anus, mouth/throat (oropharynx), penis, vagina, and vulva. The specific organs or areas affected depend on the type of HPV and the site of infection.
Certain strains of HPV can cause cervical cancer. These strains also might play a part in cancers of the genitals, anus, mouth and upper respiratory tract.
HPV can cause six types of cancer: These include anal cancer, cervical cancer, oropharyngeal cancer, penile cancer, vaginal cancer, and vulvar cancer. HPV vaccination can prevent cancer: HPV vaccines can prevent infection with disease-causing HPV types, preventing many HPV-related cancers and cases of genital warts.
One of the challenges with HPV-related cancers is that they may not present symptoms until the disease has progressed. However, there are certain signs to watch for, including persistent sore throat, difficulty swallowing, ear pain and a lump or mass in the neck.
HPV lives in the skin and the cells lining the inside of our body, so it can pass between people through close skin to skin contact, often during sex. This includes penetrative vaginal and anal sex, oral sex, touching and using sex toys with a partner, such as vibrators or butt plugs.
HPV that affects your genitals doesn't usually cause symptoms. When symptoms do occur, the most common sign of the virus is warts in your genital area. Genital warts are rough, cauliflower-like lumps that grow on your skin. They may also appear like skin tags.
In most cases (9 out of 10), HPV goes away on its own within two years without health problems. When HPV does not go away, it can cause health problems like genital warts and cancer. The types of HPV that cause warts do not cause cancer.
Most commonly there are no symptoms. Sometimes HPV can develop into warts although it is important to remember that not everyone gets warts from HPV. For anyone with a cervix, HPV may be identified during cervical screening which is now primarily an HPV test.
Most cases of HPV infection tend to be cleared by the immune system without intervention 1–2 years post-exposure; it is thought that persistent infection is most likely due to a lack of HPV-specific T-cell immunity [74].
HPV infection that does not go away on its own can cause changes to cervical cells, which lead to precancers that may become cervical cancer if left untreated. It usually takes 15–20 years for cervical cancer to develop after HPV infection.
The immune system modifications induced by HPV infection include tumor-associated macrophage differentiation, a compromised cellular immune response, an abnormal imbalance between type 1 T-helper cells (Th1) and Th2 cells, regulatory T cell infiltration, and downregulated DC activation and maturation.
High-risk HPV doesn't have symptoms
In most cases, cervical cancer is preventable if your doctor catches the warning signs early. A Pap test, sometimes called a Pap smear, finds abnormal cells on your cervix caused by HPV — but it doesn't directly test for cancer or HPV.
Autoimmune diseases (AD), specifically systemic lupus erythematosus (SLE) and rheumatoid arthritis (RA), have been associated with persistent HPV infection and with an increased risk of high-grade cervical dysplasia and cervical cancer.
Does HPV cause pain in the lower abdomen? If you are experiencing warts due to HPV and at risk of developing cancer, this might cause pain in your lower abdomen. If you notice any unusual cramps in your lower abdomen outside of regular period cramps, it's best to consult a doctor.
If you test positive for HPV and your Pap test is normal, your doctor will most likely recommend repeating the Pap and HPV screening exams in one year. If your second HPV test comes back negative, continue regular Pap and HPV tests. If your second HPV test comes back positive, your doctor may recommend a colposcopy.
Using ISH, Kamel et al. investigated 56 renal cell carcinomas for the presence of HPV DNA (subtypes 6, 11, 16, 18, 31 and 33) and concluded that the presence of HPV DNA in these tumors implicated HPV viral infection in the etiology of kidney cancer as HPV positivity was found in 52% (38).
HPVs are involved in the development of cervical, vagina, vulvar cancer in females, penile cancer in males, and anal cancers in both genders [11]. Due to the proximity of the genital tract and urinary tract, the risk of urinary tract infection with HPV is high [12].
PID is a condition characterized by inflammation of the female reproductive organs, including the uterus, fallopian tubes, and ovaries. Research indicates that certain high-risk types of HPV, such as HPV 16 and 18, may be associated with an increased risk of PID.
The putative stages, in cervical cytology, are atypical glandular cells (AGC), adenocarcinoma in situ (AIS), and Adenocarcinoma.
Infection with high-risk HPV can lead to more extensive cervical and anal dysplasia and eventually certain types of cancer. There are at least 14 high-risk strains of HPV, but two—types 16 and 18—cause the majority of HPV-related cancers, including those involving the cervix, vagina, vulva, penis, and anus.
The most common are small, hard sores called warts, but not everyone who has HPV gets them. They may be raised, flat, or shaped like a cauliflower, and they can be different sizes. They can show up on your genital area or other places, depending on the type of the virus you have. These warts often go away on their own.
If you've been diagnosed with HPV, you should know that most cases of the condition clear up on their own within two years. To help you fight HPV and stay healthy, you can take steps to build your immune system by quitting smoking, decreasing your stress level, and altering your diet.
Infection with high-risk HPV (hrHPV) types that are not cleared by the immune system can cause cervical cancers and a significant proportion of cancers of the anus, oropharynx, vagina, vulva and penis. HPV cancers take many years to develop.
First, there's no test that can tell you whether you'll clear an HPV infection. So there's no way to tell if you're going to be in that 90% or not. And if you have a high-risk type of HPV and don't clear it within 2 years, you are at a higher risk for developing cancer in the future.
