The local pressure from a tumor or bleeding (hematoma) on adjacent parts of the brain. Mass effect is diagnosed by an MRI or CT scan which shows where the mass is and what it is pushing on.
What is the meaning of mass effect?
Definition. Mass effect is a phenomenon in which a focal lesion or contusion causes surrounding areas of brain tissue or brain structures to be compressed and injured due to the degree of space that leaking blood, cerebrospinal fluid, or edema takes up within the restricted skull space.
Does mass effect mean tumor?
In medicine, a mass effect is the effect of a growing mass that results in secondary pathological effects by pushing on or displacing surrounding tissue. In oncology, the mass typically refers to a tumor.
What is mild mass effect on brain?
As the intracranial volume cannot change, any intracranial lesion which is ‘space-occupying’ may increase intracranial pressure and displace the soft tissues of the brain. This is known as ‘mass effect’. Intracranial pathological processes, such as masses and haemorrhage, can cause mass effect.
What is mass effect on bladder?
A mass (tumor) that is found on the bladder – the muscular sac in the pelvic region that stores urine – can sometimes be indicative of bladder cancer.
What does mass effect on spinal cord mean?
Spinal cord compression occurs when a mass places pressure on the cord. A mass can include a tumor or bone fragment. Compression can develop anywhere along the spinal cord from the neck to the lower spine.
What is a mass effect on the thecal sac?
Inflation of the bone tamps can result in the mechanical displacement of tumor and/or bone fragments into the spinal canal, potentially worsening or causing mass effect upon the thecal sac and resulting in symptomatic spinal cord, cauda equina, or nerve root compression.
What is mass effect in abdomen?
An abdominal mass is any abnormal growth that occurs within the abdomen. These masses have several causes, ranging from cysts to cancer. A doctor can diagnose what is causing an abdominal mass with an MRI scan, CT scan, or X-ray.
What are the side effects of brain tumor surgery?

Can brain tumor be cured?
Some brain tumours grow very slowly (low grade) and cannot be cured. Depending on your age at diagnosis, the tumour may eventually cause your death. Or you may live a full life and die from something else. It will depend on your tumour type, where it is in the brain, and how it responds to treatment.
What is the survival rate for benign brain tumors?
Rarely are benign tumors untreatable. Survival in children for all brain tumors is about 70%; long-term side effects (for example, vision problems, speech problems, decreased strength) are common. For adults, five-year survival is related to age group, with younger ages (20-44) surviving at about a 50% rate.
