A papilloma is a benign tumor that is known to grow outward. It produces leafy tumors that can develop anywhere in the body. The most common places for a papilloma can be the neck, upper chest, groin, and armpits. Because these tumors are not malignant, they are not generally considered dangerous. Surgery can be done to remove a papilloma, but only when it causes discomfort or pain.
An intraductal papilloma develops in the breast. It grows into the breast tissue and produces a small, wart-like bump. These are mainly made up of fibrous tissues and can form within the milk ducts. Occasionally, a papilloma can cause a milk duct to burst, causing a clear or bloody discharge from the nipple. When small tumors form elsewhere within the breast, they often go unnoticed.
A small wart-like growth is often called a papilloma because of its appearance. While these are not considered cancerous, they can develop into cancers because they are caused by a virus that is known to cause cancer in some parts of the body. Warts that form on the hands or feet probably won't turn into cancer. However, if a papilloma forms on the genitals or in the throat, it can be considered cancerous.
Papilloma warts that form on the genitals are often called human papillomavirus (HPV) and can lead to cancer. HPV is generally thought to be sexually transmitted, but the initial cause of the viral infection cannot be determined. In most cases, an HPV infection goes unnoticed because it is asymptomatic. The infection may go away on its own over a period of time. If the infection does not clear up on its own, it can cause cell damage and progress to cancer.
Oral human papillomavirus can also develop into cancer. This can occur when the disease comes into contact with the base of the tongue or the tonsils. Excessive consumption of alcohol and tobacco can increase the chances of contracting this type of virus.
One-third of all types of human papillomaviruses are spread through physical contact. This condition is more likely to affect people with damaged immune systems. Using oral contraceptives, having more than one sexual partner, and smoking cigarettes can significantly increase the risk of human papilloma.
