PROLONGED IRRITATION AS A CAUSE OF CANCER
Tuesday, June 28th, 2011It has been known for centuries that prolonged mechanical, physical and chemical irritation of the skin or mucous membranes can cause cancer. The edge of a broken tooth rubbing against the tongue, gall stones rubbing constantly against the gall-bladder, and smoking of short clay pipes used by labourers in Europe, have led to cancers of tongue, gallbladder and the lips respectively.
In the Godavari region of Andhra Pradesh, many men and women smoke locally rolled cigars (chutta) with the burning end inside the mouth. Some of these people are known to develop cancer of the mouth. Cancer below the umblicus, seen among Maharastrain men and women has been attributed to wearing of tight dhotis and sarees causing chronic irritation.
Excessive and continued drinking of very hot beverages may cause cancer of the throat and stomach. Prolonged irritation of the skin by chemicals or drugs may lead to skin cancer and continuous irritation of warts, pimples or slow healing sores may result in malignant tumours.
