These include the skin, lips, mouth, esophagus, urinary bladder, prostate, lungs, vagina, and cervix. It is a malignant tumor of squamous epithelium. Despite the common name, these are unique cancers with large differences in manifestation and prognosis. Most squamous-cell carcinomas are removed with surgery. A few selected cases are treated with topical medication. Squamous-cell carcinoma can generally be treated by excision or mohs surgery. Nonsurgical options for the treatment of cutaneous SCC include topical chemotherapy, topical immune response modifiers, photodynamic therapy (PDT), radiotherapy, and systemic chemotherapy. less

Basal cell carcinoma often appears as a waxy bump, though it can take other forms. Basal cell carcinoma occurs most often on areas of the skin that are often exposed to the sun, such as your face and neck. Most basal cell carcinomas are thought to be caused by long-term exposure to ultraviolet (UV) radiation from sunlight. Avoiding the sun and using sunscreen may help protect against basal cell carcinoma. It may look like a pearly white or waxy bump on your face, ears or neck, a flat, scaly, brown or flesh-colored patch on your back or chest. Some commonly used basal cell carcinoma treatments include electrodesiccation and curettage, surgical excision and topical treatments. less

It is caused by a DNA poxvirus called the molluscum contagiosum virus (MCV). This common viral disease has a higher incidence in children, sexually active adults, and those who are immunodeficient, and the infection is most common in children aged one to ten years old. MC can affect any area of the skin but is most common on the trunk of the body, arms, and legs. It is spread through direct contact or shared items such as clothing or towels. The lesions are flesh-colored, dome-shaped, and pearly in appearance. They are often 1–5 millimeters in diameter, with a dimpled center. They are generally not painful, but they may itch or become irritated. Picking or scratching the bumps may lead to further infection or scarring. Treatment is often unnecessary depending on the location and number of lesions, and no single approach has been convincingly shown to be effective. less

Corns and calluses are often confused, but they're not the same thing, Corns are smaller than calluses and have a hard center surrounded by inflamed skin. Corns tend to develop on parts of your feet that don't bear weight, such as the tops and sides of your toes, corns can even develop between your toes. Corns can be painful when pushed. Calluses usually develop on the soles of your feet, especially under the heels or balls, on your palms, or on your knees. Calluses are rarely painful and vary in size and shape, though they're often larger than corns. Pressure and friction from repetitive actions cause corns and calluses to develop and grow. Treatment for corns and calluses usually involves avoiding the repetitive actions that causes them to develop. Wearing properly fitting shoes, using protective pads and other self-care measures contains salisilic acid can help resolve them. less

The appearance of warts can differ based on the type of wart and where it is located on the body. There are usually no symptoms. Tenderness on pressure occurs with plantar warts, itching on anogenital warts. Most warts are well defined, with skin thickening. Warts are usually painless and do not pose a serious threat to a person’s health. In addition to recommending the home care treatments, such as taping and salicylic acid, the doctor may typically choose to treat the wart more aggressively. Aggressive treatment for warts are cryotherapy with liquid nitrogen, laser therapy, and surgical removal. less
