A benign tumor is an effect of DNA mutations. It manifests itself in an abnormal growth in your tissues. But it is not deadly and can be removed surgically.
What does tumor mean? It means swelling or inflammation. How does it form? It starts when cancer cells bond with each other and the growth starts inside the DNA of your cells through genetic mutations.
The characteristics of benign tumors are:
1. It is non-cancerous. DNA mutations caused it and the cells grow abnormally but not aggressively.
2. It does not invade other tissues and is contained in its origin unlike a malignant tumor.
Common examples of non-cancerous tumors are moles, myomas or uterine fibroids. They are rarely life-threatening and so prevention of their growth is not a necessity. In fact, many of them do not need to be treated or removed.
But it is recommended that tumors although benign be surgically removed if...
they cause symptoms like bleeding, to appear. Bleeding is likely in cases of myomas.
they pose a risk to your health because they obstruct other organs or stimulates your endocrines to overproduce hormones. Such DNA mutations are harmful because too much hormones increase risk for cancer.
they become a cosmetic concern like a mole on your face. Sometimes changes in moles should also be a concern because they may mean melanoma signs.
Once it is removed, a tumor that is benign usually doesn't grow back. Benign tumors also rarely or never develop into cancer at all. However, some types of tumors such as teratomas can turn malignant.
Two other methods of removing a non-cancerous tumor in addition to surgery are through radiation and cryosurgery.
In cryosurgery, thin probes with liquid nitrogen are inserted into the tumor to freeze it. Radiation and cryosurgery become an option when the mass can't be reached by the surgeon.
A word of caution, however, for the kind of therapy that emits ionizing radiation: It is a proven fact that radiation causes cancer.
