Doctor insights on: Excision Femur Bone Cyst Or Benign Tumor

Share

Cyst (Definition)

A cyst is a structure or mass that consists of a cellular lined sac. It is typically filled with fluid but may be filled with solid material. It can be congenital, traumatic, or acquired. They may develop nearly anywhere in the body and usually require complete excision for eradication or they are likely to recur. Fluid filled sacs that are not cellular lined ...Read more

Cyst can cause pain: A bone cyst in the distal femur is a common finding on x-ray of the knee. It is possible that the cyst can cause pain and a small effusion. The next step is to see a medical provider and have an MRI performed on the knee including the distal femur to evaluate the cyst and knee joint in more detail. ...Read more

Hi, what's the difference between a benign cyst and a benign tumor on optic nerve? Thanks

Hi, what's the difference between a benign cyst and a benign tumor on optic nerve?  Thanks

Good question, but: Not always a simple answer. Some tumors form cysts. Generally a cyst is trapped fluid in a surrounding layer of non-tumor tissue. "Benign" is a complex term in the nervous system. A tumor cell type can be benign by its growth pattern (doesn't invade or "metastasize") but still a concerning problem because of where it is (on an eye nerve, for example). See ophthalmologist (not optometrist). ...Read more

Hi, what's the difference between benign cyst and benign tumor on optic nerve? Thank you.

Hi, what's the difference between benign cyst and benign tumor on optic nerve? Thank you.

Cyst & tumor differ: A cyst is defined as an open space (sac) with an epithelial lining. This space may be filled with fluid, cellular debris, empty, etc. In general, a tumor is a solid growth, but may have cystic components. They can be composed of many different cell types. In this case, both are benign, but being on the optic nerve, they could still cause problems due to compression. ...Read more

What can cause a benign tumor in thethin bone in upper arm?

It happens: They just happen in many cases. Some run in families (genetic). Symptoms can be from growth of the tumor or irritation of nerves and other structures nearby. Sometimes they are found when the bone breaks for bone weakness from the tumor. In other cases they are found when a person is evaluated for another problem. ...Read more

Neoplasms (Definition)

"tumor" literally translates as "mass", so even a fresh bruise could be called a "tumor". Doctors use the term "neoplasm" (tranlates literally as new growth) to describe tumors that are abnormal growths of cells. These may be benign or malignant; "malignant" = cancer. In everyday usage, we use "tumor" ...Read more

Benign Tumor (Definition)

A tumor by any other name is a growth. It can be either benign or malignant, differentiated based upon the potential to spread (a malignant tumor is, by definition, a cancer). The best way to determine this is by a tissue biopsy, but we can make better predictions based on the organ of origin, physical ...Read more
