Francium is radioactive.
No.
Benign brain tumors do not infiltrate nearby tissues but can cause severe pain, permanent brain damage, and death
No
No, it cannot.
Brain tumors can develop from abnormal growth of cells in the brain. The exact cause is not always known, but factors such as genetic mutations, exposure to certain chemicals or radiation, and family history can contribute to their development. Brain tumors can also arise spontaneously without a clear cause.
The cause of primary brain tumors is unknown, but people who work with rubber and certain chemicals have a greater-than-average risk of developing them
No, a knock on the head does not directly cause a brain tumor. Brain tumors are typically caused by genetic mutations or abnormal cell growth in the brain. However, head injuries can increase the risk of developing certain types of brain tumors in some cases.
It is possible. Studies have shown that workers who are regularly exposed to radiation are much more likely to develop brain tumors later in life. However this is not the only factor and it is not really known for certain what causes most brain tumors.
The most common primary brain tumors include gliomas such as astrocytomas, ependymomas, and oligodendrogliomas
Primary brain tumors can be benign or cancer.Usually, benign tumors are often removed, and that they seldom grow back.Benign brain tumors usually have a clear border or edge. Cells from benign growths rarely invade tissues around them.They don't spread to other parts of the body.Benign tumors can continue sensitive areas of the brain and cause serious health problems.Unlike benign tumors are sometimes life-threatening.Benign brain tumors may become turn into cancer.Malignant brain tumors contain cancer cells:Malignant brain tumors are generally more serious and sometimes are a threat to life.They are likely to grow rapidly or invade nearby healthy brain tissue.Cancer cells may break free from the malignant brain cancer and spread to other parts of the brain or to the medulla spinal.
Benign brain tumors are noncancerous growths that usually grow slowly and do not spread to other tissues. Although they are not cancerous, these tumors can still cause complications due to their size and location, putting pressure on surrounding brain tissue.There are several types of benign brain tumors:ChordomasCraniopharyngiomasGangliocytomasGlomus jugulare tumorsMeningiomasPineocytomasPituitary adenomasSchwannomas
Malignant brain tumors do not have distinct borders
