Lymphatic Diseases—Benign Tumors

Also called: Benign cancer, Benign neoplasms, Noncancerous tumors

Tumors are abnormal growths in your body. They can be either benign or malignant. Benign tumors aren’t cancer. Malignant ones are. Benign tumors grow only in one place. They cannot spread or invade other parts of your body. Even so, they can be dangerous if they press on vital organs, such as your brain.

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.

Treatment often involves surgery. Benign tumors usually don’t grow back.

The lymphatic system is a network of tissues and organs. It is made up of

• Lymph – a fluid that contains white blood cells that defend against germs
• Lymph vessels – vessels that carry lymph throughout your body. They are different from blood vessels.
• Lymph nodes – glands found throughout the lymph vessels. Along with your spleen, these nodes are where white blood cells fight infection.

Your bone marrow and thymus produce the cells in lymph. They are part of the system, too.

The lymphatic system clears away infection and keeps your body fluids in balance. If it’s not working properly, fluid builds in your tissues and causes swelling, called lymphedema. Other lymphatic system problems can include infections, blockage, and cancer.
