The tumors that begin to grow in the brain are called primary brain tumors and may or may not be cancerous. There are other types of brain tumors that occur when the cancer originated elsewhere in the body metastasizes, spreading to the brain. Metastatic brain tumors are 4 and 5 times more frequent than primary brain tumors. There are several factors that affect the signs and symptoms that occur in these cases, including the size of the tumor and its location within the brain. Symptoms can be both subtle and persistent, such as a dull headache or weakness on one side of the body.
It is common for headaches to occur in the event of a brain tumor. Migraines related to this condition are usually deaf and constant, while throbbing pains occur less frequently. In these cases, the discomfort tends to be intense in the morning and to improve during the course of the day. Migraines associated with brain tumors, in general, are not serious, but they go on to last over time, and they can be intensified with movements such as bending, coughing or sneezing. Many people experience headaches and most of them are not caused by brain tumors. However, if you notice a significant change in the pattern of your pain or if you develop other symptoms, consult your doctor immediately.
Personality and mental changes
Severe personality or mood changes and decreased intellectual functioning are symptoms that can occur when there are brain tumors. These changes can be subtle or dramatic, ranging from the deceleration of mental activity to hallucinations. Some brain tumors have the potential to cause memory problems. Others cause symptoms similar to those of depression, including decreased energy, excessive sleep, and loss of interest in daily activities.
Many people with brain tumors experience seizures at some point during the course of the disease. Crises can be mild or severe. A seizure is capable of generating spasms in an arm or leg or of affecting the whole body through fainting and generalized agitation. The type of seizure usually determines the location of the tumor in the brain. A seizure that occurs for the first time in an adult without an obvious cause (such as a head injury) usually requires tests to check or rule out the presence of a tumor.
Nausea and vomiting
Nausea and vomiting may occur when there is a brain tumor, due to increased pressure within the brain.Nausea or vomiting caused by a sudden change in position, such as spinning rapidly in bed, suggests a possibility of a brain tumor. It is also known that there is vomiting without nausea. Although the vast majority of cases of nausea and vomiting are not related to the presence of a brain tumor, when it is accompanied by other symptoms (such as headache or recently reported seizures) these symptoms become more suspicious.
Stroke-like symptoms may occur if a brain tumor alters normal brain functions through increased pressure or tissue destruction in a specific area. The symptoms experienced are related to the part of the brain that is being affected. For example, sometimes there is numbness or weakness in an arm, leg or side of the face that often gets worse as the tumor grows. Vision problems and speech disorders are other brain tumor symptoms that mimic a stroke.
