Can Spiders Cause Cancer?
WouterSpiders are often considered dangerous and venomous, but it is not uncommon for spider bites to cause serious health issues. Venom can cause a variety of symptoms, including pain, swelling, nausea, and a rapid pulse. It is best to see a doctor or emergency room if you experience severe allergic reactions, or if you notice more than two symptoms after being bitten.
In addition to being venomous, some spiders can cause necrosis, which is a skin injury that causes the skin to die. This condition usually takes several weeks to heal.
The venom from some spiders, such as brown recluse and black widow, can be toxic. These venoms can cause systemic illnesses, such as heart failure. They also cause a wide range of skin lesions. Some people are sensitive to the venom, and others are not.
Several species of venomous spiders are common, though some are rarer. There are over 30,000 species of spiders in the world, many of which are considered medically relevant.
Historically, the white tailed spider and the black house spider have been linked to necrotising arachnidism, or skin inflammation. However, the Centers for Disease Control and Prevention notes that these spiders rarely cause serious injuries.
There are other types of venomous spiders, such as the woodlouse and the widow spider. Woodlouse spiders pierce the skin, producing a burning sensation and a sharp nip. Meanwhile, the widow spider can be found in undisturbed areas such as outdoor toilets.
