Before too long, though, the blister came back, and this time it was worse. My feet wept from the build-up of fluid, and then the blisters began to spread like a rash across my toes, on the bottom of my feet, and finally up the sides of my feet. It was agony. The incessant itch would wake me up at night and my skin bled from my scratching. Any skin I managed not to scratch wasn't much better, and would often fall off in sodden layers as the blisters oozed fluid all over my feet. I needed crutches to get around, making my daily commute a struggle.
Nonmelanoma skin cancer frequently affects sun-exposed areas, including the head, face, neck, hands, and arms. There are two types of nonmelanoma skin cancer, including basal cell carcinomas (they may be dome-shaped with visible blood vessels and can look like open sores that won’t heal) and squamous cell carcinomas (they may form a crusty lump on the skin or rough, scaly patches that sometimes bleed). Melanoma (above), the most dangerous type of skin cancer, may cause dark spots, changes in moles, or a bruise that doesn’t heal. Depending on what type of skin cancer you have and how severe it is, treatment can include surgery, radiation, and chemotherapy.
The most common fungi to cause skin infections are the tinea group of fungi. For example, athlete's foot (tinea pedis) is a common fungal infection of the toes and feet. Tinea infection also causes ringworm (tinea corporis) and ringworm of the scalp (tinea capitis) . It also causes many fungal nail infections . A common fungal infection of the mouth and of the vagina is called thrush. This is caused by an overgrowth of candida which is a yeast (a type of fungus). Small numbers of candida commonly live harmlessly on the skin. However, certain conditions can cause candida to multiply and cause infection . Candida is also sometimes the cause of some fungal nail infections.
