Gliomas can be not cancer (benign) or cancer (malignant). They make up about 3 in 10 of all tumors that start in the brain. If a brain tumor isn’t cancer, it may still need to be treated. This is because even small tumors can press on normal brain tissue and cause problems.
Why do glial cells cause tumors?
A glioma is a tumor that forms when glial cells grow out of control. Normally, these cells support nerves and help your central nervous system work. Gliomas usually grow in the brain, but can also form in the spinal cord. Gliomas are malignant (cancerous), but some can be very slow growing.

How many different types of stomach cancers are there?
There are 2 main types of stomach adenocarcinomas: The intestinal type tends to have a slightly better prognosis (outlook). The cancer cells are more likely to have certain gene changes that might allow for treatment with targeted drug therapy. The diffuse type tends to grow spread more quickly.
What are stomach tumors called?
Stomach cancer, also known as gastric cancer, can affect any part of the stomach. In most of the world, stomach cancers form in the main part of the stomach (stomach body).

What is a non cancerous stomach tumor?
Stomach Tumors That Are Noncancerous. Stomach polyps (uncommon noncancerous round growths that project into the stomach cavity) may become cancerous (that is, they are precancerous). Therefore, polyps are usually removed using endoscopy. Through the endoscope, an electrical current (electrocautery) or heat (thermal obliteration)…
What are the symptoms of a small tumor in the stomach?
These tumors often grow into the empty space inside the gastrointestinal (GI) tract, so they might not cause symptoms right away unless they are in a certain location or reach a certain size. Small tumors might not cause any symptoms and can be found accidentally when the doctor is checking out some other problem.
What are gastrointestinal stromal tumors (GISTs)?
Most gastrointestinal stromal tumors (GISTs) develop within the wall of the stomach or small intestine. These tumors often grow into the empty space inside the gastrointestinal (GI) tract, so they might not cause symptoms right away unless they are in a certain location or reach a certain size.
What is the best non-invasive procedure for the diagnosis of gastric cancer?
Conventional CT scan is another non-invasive procedure in the investigation of distal gastric and duodenal tumors. In the last few years, endoscopic ultrasonography has been proven to be helpful in the diagnosis of submucosal tumors.
