A brain tumour is essentially brain cancer, a growth that develops on or within the brain that can either be benign or malignant.

There are a huge variety of brain tumours, and their level of seriousness depends entirely upon where they are located and how advanced they have become. Most tumours that grow on the outside surface of the brain, and even some that grow inside it, can be removed surgically. Some of those that cannot be surgically removed can be treated with either chemotherapy, radiotherapy, or a combination of the two. Even if a complete cure is not possible in these cases, it can sometimes be possible to retard the growth of the tumour and prolong the life of the patient.

So although some brain tumours are incurable and can be fatal, these are nowadays in a minority- the majority of brain tumours can be succesfully treated.

What is the difference between the brain and the cranial?

The brain is an organ responsible for processing information and controlling bodily functions. The cranium is the skull bone that encases and protects the brain. The brain and the cranium are distinct entities, with the brain being the organ housed within the cranium.


What is the difference between brain tumors and brain cancer?

The terms "brain tumor" and "brain cancer" are related but not synonymous. Here's the key difference between the two: Brain Tumor: A brain tumor is a broad term that refers to an abnormal growth or mass of cells within the brain or the surrounding tissues. Brain tumors can be either benign (non-cancerous) or malignant (cancerous). Benign brain tumors typically grow slowly and do not invade nearby tissues or spread to other parts of the body. They can, however, cause symptoms if they press against surrounding structures. Malignant brain tumors, on the other hand, are considered brain cancer. They are aggressive, tend to invade nearby healthy brain tissue, and can potentially spread to other parts of the central nervous system. Malignant brain tumors are often referred to as primary brain cancer. Brain Cancer: Brain cancer specifically refers to malignant tumors that originate within the brain or central nervous system (CNS). These tumors are composed of cancerous cells that can grow rapidly and invade nearby brain tissue. Brain cancer is categorized into different types based on the specific cell types and tissues from which they arise. The most common primary brain cancers include gliomas (e.g., glioblastoma multiforme), meningiomas, and medulloblastomas, among others. Unlike benign brain tumors, brain cancer has the potential to metastasize (spread) within the CNS but rarely metastasizes outside the brain or spinal cord to other parts of the body. In summary, a brain tumor is a general term for any abnormal growth in the brain, which can be either benign or malignant. Brain cancer, on the other hand, specifically refers to malignant tumors that originate within the brain or CNS. It's important to note that the diagnosis, treatment, and prognosis for brain tumors and brain cancer can vary widely depending on factors such as tumor type, location, size, and stage. Treatment may include surgery, radiation therapy, chemotherapy, or a combination of these approaches, and it should be determined in consultation with medical professionals.


What is The sequence of brain regions from the evolutionary oldest to newest?

The brain region that seems to have the oldest evolutionary history is the brain stem. The brain stem is located at the brain's base and is joined to the spinal cord. The brain stem contains the midbrain, pons and medulla oblongata.


How does the size and complexity of a blue whale's brain compare to that of a human?

The blue whale's brain is much larger and more complex than a human's brain. It is the largest brain of any animal on Earth, but its structure and functions are different from a human's brain.
