The majority of brain tumors have abnormalities of genes involved in cell cycle control, causing uncontrolled cell growth. Brain tumors arise from one of three sources: Brain tissue – this is called a primary tumor The gene mutation that predisposes someone to develop a particular type of brain tumor may be present at birth in some cases, but there are also probably external environmental factors that trigger the development of a tumor. This condition affects people of all ages indiscriminately, appearing with mixed symptoms. But researchers have found some of the changes that occur in normal brain cells that may lead them to form tumors.

The causes of the gene damage that produce a tumor likely differs between the various types of tumors, and in most cases, the causes are not well understood. These abnormalities are caused by alterations directly in the genes, or by chromosome rearrangements that change the function of a gene. The exact causes of brain tumors in dogs are not known. These types of tumors are called secondary or metastatic brain tumors. In most cases, the following steps occur as a primary brain tumor develops: Genetic mutations occur in healthy cells.

Pituitary tumors affect the optic nerve, causing vision problems, due to their development. Exposure. Muscle Weakness Dreamstime. A brain tumor can be pretty dangerous if not detected on time. These genetic mutations allow the cells to grow much faster than they normally would. Brain tumors affect both cats and dogs. As the tumor grows, it creates pressure on and changes the function of surrounding brain tissue, which causes signs and symptoms, such as headaches, nausea and balance problems.

Time is of the essence and understanding the signs and symptoms of a brain tumor is vital for early detection. Risks and causes of brain tumours. About nine in 10 are benign. A primary brain tumor results from a genetic mutation in certain nerve cells in the brain (neurons) that causes them to grow too quickly. Researchers and doctors do not know exact cause of brain tumors. Neurotransmitter changes, location, type of tumor, genetic factors, and integrity of the blood-brain barrier may all be some of the factors involved. A brain tumor occurs when abnormal cells form within the brain. Brain tumor symptoms can include: … Brain tumours cause symptoms because: they take up space inside the skull when they grow; of their position in the brain ; The symptoms can develop gradually over some months or even years if the tumour is slow growing.
