What are Moles/Warts/Keloids/Skin Tags?
A mole (nevus) is a pigmented (colored) spot on the outer layer of the skin (epidermis). Moles are one thing that is common to all humans. Every person has moles, maybe 1, maybe 40. Moles are not a cause for concern unless they develop certain signs like: Itching / Increase in size / Change of colour. In fact they are considered to be a beauty spot by many, especially on the face area. Some even consider this to be a sign of good luck and prosperity.
Moles can appear anywhere on the skin. They are of different shapes and sizes. Moles are usually brown to black in colour due to pigment melanin. Sometimes moles can be skin coloured. Moles are pre-determined at birth. They develop usually in the first 20 years of life and over the years due to sun exposure they can increase in numbers and darken in colour. Moles can be round, oval, flat, or raised. They can occur singly or in clusters on any part of the body. Most moles are brown, but colors can range from pinkish flesh tones to yellow, dark blue, or black..
A wart is a hardened, bumpy, or rough piece of skin that grows faster than normal. Warts are caused by infection with the human papilloma virus (HPV). Most warts are harmless, but the virus that causes warts is contagious and can be spread by direct contact with others. Warts may develop anywhere on the body, including the bottom of the feet, palm of the hands, fingers, and genitals. Warts are typically brown or flesh-coloured, although genital warts may also appear pink or red.
A skin tag is a small flap of tissue that hangs off the skin by a connecting stalk.Skin tags are not dangerous. They are usually found on the neck, chest, back, armpits, under thebreasts, or in the groin area. Skin tags appear most often in women, especially with weight gain, and in elderly people. Skin tags usually don't cause any pain. However, they can become irritated if anything, such as clothing or jewelry, rubs them.
A keloid, sometimes referred to as a keloid scar, is a tough heaped-up scar that rises quite abruptly above the rest of the skin. It usually has a smooth top and a pink or purple color.Keloids are irregularly shaped and tend to enlarge progressively. Unlike scars, keloids do not regress over time.
Cause of Moles/Warts/Keloids/Skin Tags
Moles occur when cells in the skin grow in a cluster instead of being spread throughout the skin. These cells are called melanocytes, and they make the pigment that gives skin its natural color. Moles may darken after exposure to the sun, during the teen years, and during pregnancy.
Common warts are actually an infection in the top layer of skin, caused by viruses in the human papillomavirus, or HPV, family. When the virus invades this outer layer of skin, usually through a tiny scratch, it causes rapid growth of cells on the outer layer of skin – creating the wart.
Keloids can develop from most types of skin injuries, including:
Skin tags are more common among people with diabetes as well as people who are overweight or obese — conditions that often go together. The friction created by skin rubbing against skin, a side effect of being overweight, is what causes skin tags in certain people, and explains why skin tags often grow in body folds.
