There are many different types of benign growth. They can develop internally as well as on the skin— most of them can grow considerably bigger than warts! However, benign growths are usually easy to treat—in many cases it is best and easiest just to leave them alone. Removal may be recommended if they are causing cosmetic problems, discomfort or interfering with normal body functions, for example, by causing a blockage of the intestine. Also, if there is any doubt as to whether growths are benign or malignant, they should be removed or at least sampled so that they can be examined under the microscope. The cells of a benign growth are always well differentiated, that is, they look very similar to the normal cells of the organ in which they occur. Once completely removed, benign growths are very unlikely to grow back.
These then are benign growths. Malignant growths (cancer) develop when there is a much more serious disturbance of the normal relationship between our cells and the control over growth and differentiation.
