Thymus Cancer: Risk Factors
What is a risk factor?
A risk factor is anything that may increase your chance of having a disease. Risk
factors for a certain type of cancer might include smoking, diet, family history,
or many other things. The exact cause of someone’s cancer may not be known. But risk
factors can make it more likely for a person to have cancer.
Things you should know about risk factors for cancer:
Risk factors can increase a person's risk, but they don't always cause the disease.
Some people with risk factors never develop cancer. Other people can develop cancer
and have no risk factors.
Some risk factors are very well known. But there is ongoing research about risk factors
for many types of cancer.
Some risk factors, such as family history, may not be in your control. But others
may be things you can change. Knowing the risk factors can help you make choices that
might lower your risk. For example, if an unhealthy diet is a risk factor, you may
choose to eat healthy foods. If excess weight is a risk factor, you may decide to
try to lose weight.
Who is at risk for thymus cancer?
Anyone can get thymus cancer. Fortunately, this is a rare cancer. There are very few
factors linked to an increased risk for thymus cancer. These include:
Older age. The risk of this cancer goes up with age. It’s very rare in children and adults.
Race and ethnicity. Asian Americans and Pacific Islanders have the highest risk for thymus cancer of all
racial groups in the U.S.
Certain autoimmune diseases. Sometimes people with certain autoimmune diseases, such as myasthenia gravis, red
cell aplasia, or hypogammaglobulinemia, are later found to have thymus tumors. It’s
thought that the tumor is most likely the cause of these conditions (called paraneoplastic
syndromes), rather than the other way around. But sometimes symptoms from these conditions
allow a thymus tumor to be found at an early stage.
What are your risk factors?
If you are concerned about thymus cancer, talk with your healthcare provider about
your risk factors. Unfortunately, the known risk factors for thymus cancer are not
under your control. But if you are at increased risk, being aware of possible symptoms
might help find thymus cancer early, when it could be easier to treat.
