The bulge of
is likely to be warts (yóu).

Why do the body develop warts?
"
warts are often called " warts " and "stings". As a benign growth on the surface of the skin, how do warts "appear"? After the skin mucosa lesions of
, human papillomavirus (HPV) enters the skin epithelial cells;
then the virus replicates and proliferates in it, causing abnormal differentiation and proliferation of epithelial cells , forming warts. For example, common warts , flat warts , plantar warts .
usually needs to meet two conditions for wart infection:
has broken skin;
has low immunity.
When the skin is damaged, the virus has an opportunity to take advantage of. If the autoimmunity can kill the virus, the infected person will not be infected; if the immunity is not enough to compete with the virus, the virus can cause chaos on the skin and grow warts.
Therefore, the skin in the exposed area of has a higher chance of contacting the virus, and is the high incidence of warts .

5 warts are related to HPV infection
"
HPV is a big family, including more than 200 different subtypes, among which low-risk infections account for the majority, which generally only leads to the generation of "warts". There are more than a dozen types of high-risk HPV, and it is currently found that HPV16 and 18 are related to 70% of cervical cancer .
Due to the different subtypes of virus infection in humans and the different locations of infection, the shapes of warts are also different, and the treatment methods are also different.
Common warts: the susceptible part
commonly known as "sting" or "sting", and is often related to HPV infections of types 1, 2, 4 and 7.
Preferential position : Parts that are prone to trauma, such as fingers, elbows, knees and face, can spread to any part of the body.
Features : The warts are gray-brown, brown or keratinous papules with a rough surface and can appear individually. They can also cause the warts to be "inoculated" due to scratches, and are arranged in a linear manner.
Treatment method : Usually there are no conscious symptoms and will subside within 2 to 4 years.
Filamentous warts : The most common one on the head and neck
It is a special subtype of ordinary warts.
Preferential position : eyelids, perioral oral and neck.
Features : The warts are filamentous or elongated, with narrow roots and finger-like protrusions on the surface.
treatment methods : including resection, clipping, scraping and liquid nitrogen freezing, and can also be treated with antiviral drugs or retinoid drugs.
However, when liquid nitrogen freezes, patients with dark skin may leave long-lasting hypopigmentation spots after treatment, so they should be selected with caution.
Plantar warts: Large foot will cause pain
Preferential position : Sole foot
Features : Skin lesions are initially small and shiny papules , which slowly grow into soybean size or larger, with a central depression similar to an anthill, manifested as single or multiple "mosaic"-like skin lesions. Larger or deeper plantar warts can cause pain due to pressure when walking.
Treatment method : Due to the hypertrophic stratum corneum in the foot, plantar warts are difficult to treat, and it is difficult for the drug to reach the deep layer effectively. You can try externally applying corrosive acids, liquid nitrogen freezing and other methods.
For those with a large and thick rash, they can be combined with retinoic acid , antiviral, and regulated immune system treatment.
Flat warts: It is most common on the face
Flat warts are related to HPV infections of types 3, 10, 26~29, and 41.
Preference position : Most commonly occur on the back of hands, arms and face, and children and adolescents are high-profile people.
Features : shaped like a round or oval shape to the size of a soybean, and can be light brown, pink or skin tone.
Treatment method : Common topical drugs include 0.05%~0.1% retinoic acid ointment, 5% imiquimod cream, etc., but they need to be considered based on the characteristics of the skin lesions, the site of the disease, etc., and they cannot be used blindly.
For example, some drugs can cause pigmentation, facial flat warts should be used with caution. For those with less skin lesions, physical therapy can be used, and facial treatment should also be used with caution.
General warts : Near the genital organs
This type of "wart" is also called anal genital warts.
Preferential position : At the junction of the external genitals and the perineum, perianum or skin mucosa, it is a sexually transmitted disease and can also be transmitted through the birth canal or direct contact.
Features : Skin lesions are usually dispersed, pedicle-free, smooth-surface warts, and large fusion plaques may appear, showing skin color, brown or white (especially in wet areas).
Treatment method : Patients need to remove warts as early as possible, eliminate infections around warts as much as possible, and reduce recurrence; 0.5% podophyllotoxin tincture (disabled for pregnant women), etc. can be used topically, or physical methods or combined with photodynamic therapy .

Warts on the skin
These behaviors are not recommended to operate
"
➊ Use plasters indiscriminately
especially those that grow on the soles of the feet. They blindly use corn ointment to apply money, and not only waste money, the key is that it is difficult to take effect if it is not correct.
➋ Search the online and get the seat by yourself
. Because there are many types of warts, ordinary people cannot judge it. It is very easy to misjudgment by searching the seat by yourself. If it causes excessive treatment and delayed treatment, it will not be worth the cost.
➌ Pruning
warts by yourself is contagious. Eliminating one or two with external forces is not only ineffective in treating them, but also at risk of local infection.

1 // Vaccination as soon as possible
HPV vaccine can reach more than 90%, and the earlier the vaccination, the better. For people who already have sex, the protection power has been reduced, but it can still reach 60-70%.
2 // does not mix private items
HPV virus can be transmitted through indirect contact, so it is best not to share private items.
3 // Pay attention to sexual hygiene
HPV virus can be transmitted through sexual intercourse. Therefore, it is recommended to avoid premature sex (under 18 years old), avoid having sex during menstruation and puerperal periods, eliminate multiple sexual partners, etc.
4 // Improves autoimmunity
People with strong immunity are more difficult to damage their health even if they suffer from low-risk HPV infection. If they have weak immunity, they will have the virus to take advantage of. Balanced diet, regular exercise, and adequate sleep are the easiest ways to improve immunity.
