Should a painful benign adrenal adenoma on the left side be left untreated?
About adrenal adenoma:
Usually we recommend surgery for adenomas over 4 cm despite their characteristics in MRI or CT scan. Furthermore, the mass dimensions have increased during the last few years, that is another criteria to remove it.
You should also exclude hormonal production by checking the adrenal gland hormonal secretion, if you have noticed that during these years you have gained weight, have high blood pressure, Diabetes etc.
You should probably discuss once again with your physician about it.
Hope I have answered your query.
