Screening tests have risks.
Decisions about screening tests can be difficult. Not all screening tests are helpful and most have risks. Before having any screening test, you may want to discuss the test with your doctor. It is important to know the risks of the test and whether it has been proven to reduce the risk of dying from cancer.
The risks of neuroblastoma screening include the following:
Neuroblastoma may be overdiagnosed.

Many things increase your risk for a blood clot. These include:
Having slowed blood flow, abnormal
clotting, and a blood vessel injury.
Age. As people get older (especially older than age 70),
they are more likely to develop blood clots.
overweight increases the risk for developing clots.
anticoagulant medicine as prescribed, unless your doctor tells you to stop taking it.
Slowed blood flow
When blood does not circulate
normally, clots are more likely to develop. Reduced circulation may result
Long-term bed rest, such as if you are
confined to bed after an operation, injury, or serious
Traveling and sitting for a long time, especially when
traveling long distances by airplane.
Leg paralysis. When you use your muscles, the muscles contract,
and that squeezes the blood vessels in and around the muscles. The squeezing
helps the blood move back toward the heart. Paralysis can reduce circulation
because the muscles can't contract.
Some people have blood that
clots too easily or too quickly. People with this problem are more likely to
form larger clots that can break loose and travel to the lungs. Conditions that
may cause increased clotting include:
Inherited factors. Some people have an
inherited tendency to develop blood clots that can lead to pulmonary
Family history of close relatives, such as a sibling, who has had deep vein thrombosis or pulmonary embolism.
Cancer and its treatment.
Blood vessel diseases, such as varicose veins, heart attack, heart failure, or a stroke.
Pregnancy. A woman's risk for
developing blood clots increases both during pregnancy and shortly after
Using hormone therapy or birth control pills or patches.
Injury to the blood vessel wall
Blood is more
likely to clot in veins and arteries shortly after they are injured. Injury to
a vein can be caused by:
that involved the legs, hips, belly, or brain.
A tube (catheter) placed in a large vein of the body
(central venous catheter).
Damage from an injury, such as a broken hip, serious burn, or serious infection.
