Why do benign tumors grow back?

The exact cause of a benign tumor is often unknown. It develops when cells in the body divide and grow at an excessive rate. Typically, the body is able to balance cell growth and division. When old or damaged cells die, they are automatically replaced with new, healthy cells.

Benign tumors generally have a slower growth rate than malignant tumors and the tumor cells are usually more differentiated (cells have more normal features). They are typically surrounded by an outer surface (fibrous sheath of connective tissue) or stay contained within the epithelium.

Do benign tumors need to be removed?

AG: Benign tumors will sometimes be removed for cosmetic reasons. Some fibroids or moles can grow or spread to other parts of the body. They should be frequently checked to make sure they’re not becoming precancerous. Even though most benign tumors are harmless and can be left alone, it’s important they be monitored.

Can a tumor disappear?

The process is typically called “spontaneous regression” or “spontaneous remission,” and a considerable body of literature confirms that cancer and benign tumors do indeed “disappear” and, in exceptional cases, patients are cured of the disease — in which case the phrase “miraculous healing” is sometimes invoked.

This sounds scary, but many people can live months or years with the right treatment. For them, the cancer becomes more like a chronic illness, such as diabetes or heart disease.

Does Chemo shorten your life?

Cancer survivors tend to have shorter telomeres than normal persons at the same age. This means that they are older than their actual years. It could be the intensive and toxic chemotherapy and radiation therapy that has led to this finding say researchers.
