Benign tumors can appear anywhere in the body

As said previously, benign tumors and cysts can appear in any organ in the body, including the brain and the heart.

The most common types of benign tumors are leiomyomas ( develop in the smooth muscle layer of internal organs); lipomas ( develop in adipose tissue and more prevalent in babies and children); neuromas ( in nerve tissue) and hemangiomas ( in blood vessels).Tumors that tend to interfere with hormone production and regulation are adenocorticoadenomas, thyroid adenomas and pituitary adenomas. Osteoblastomas ( benign tumors found in the bones) are very scarce. Leiomyomas can develop on the smooth muscle layer of any organs, but are more prevalent in the uterus, small bowel and oesophagus.

Cysts in the other hand have a higher tendency to develop in the ovaries ( ovarian cysts), popliteal fossa ( Baker cysts), within various glands in the body ( sebaceous cysts, Bartholin cysts, pineal cysts, chalazions, etc.), and within the pancreas and the kidneys.
