Benign neoplasm

• Benign neoplasms may grow large but do not spread into, or invade, nearby tissues or other parts of the body.
• Malignant neoplasms, on the other hand, can spread into, or invade, nearby tissues.
• They can also spread to other parts of the body through the blood and lymph systems.
• Also called tumor.

Benign mucinous tumor of the ovary

What are tumors?

• Tumors are made up of extra cells.
• Normally, cells grow and divide to form new cells as your body needs them.
• When cells grow old, they die, and new cells take their place. Sometimes, this process goes wrong.
• New cells form when your body does not need them, and old cells do not die when they should.
• These extra cells can divide without stopping and may form tumor.
• If the cells grow uncontrollably and start invading other cells, they are called malignant and if they do not invade, they are called benign.
