We generally call small growths on the skin warts or warts. But they both occur for different reasons. The main reasons are:
Viral infection (for warts): Warts are caused by the human papillomavirus (HPV). This virus enters the body through small cuts or scratches on the skin and causes excessive growth of cells.
Skin friction (for warts): Skin tags are caused by constant rubbing of skin against skin or clothing in areas where the skin is folded (neck, armpits, eyelids). They are not contagious.
Risk of transmission: Warts are contagious. The virus can be spread to someone else by touching the warts of an infected person or by sharing towels or soaps used by them. It can also spread from one place to another within the body.
Immunity and hormones: When the body’s immune system is weakened, the risk of getting warts increases. However, warts are mainly associated with hormonal changes (pregnancy), diabetes, and obesity.
Genetic causes: If someone else in the family has such skin problems, the next generation is more likely to get warts or warts.
