About Brain Tumor
Brain Tumor: Our brain is made up of spongy tissue. The following parts are the protective coverings that protect the brain, the bony skull, the watery fluid between the layers of the meninges. This is called cerebrospinal fluid. This fluid is also present in spaces in the brain called ventricles. Actions like breathing, walking, talking, personality, emotions, memories, seeing, hearing, touching, tasting, smelling, and sensory activities all occur in the cerebral cortex. Various signals and messages are constantly traveling from the brain to the body and from the body to the brain through the neural network.
Peripheral Parts Of The Brain
Some nerves connect directly from the brain to parts of the head, such as the eyes and ears. The rest of the nerves travel from the spinal cord and secure from the brain to other parts of the body. In the brain and spinal cord, cells called glial cells surround nerve cells (nerve cells) and keep them from displacing.
The brain consists of three parts.
1. Cerebrum:
How the body analyzes sensory information from the world around us and responds accordingly. Issues orders in the matter. The cerebrum also controls everything, like reading, thinking, learning to speak, emotions, etc. The cerebrum is divided into a right hemisphere and a left hemisphere. The right hemisphere works on the left side of the body, while the left hemisphere works on the right side of the body.
2. Cerebellum:
It is the cerebellum which is the source of coordination between muscles for body balance and movements.
3. Brain Stem:
Connects the brain to the spinal cord (spinal cool). It controls activities necessary for living, like breathing, heart beating, digestion, and sleeping.
Parts Of The Brain
A brain tumor is an abnormal growth of cells somewhere in the brain and forms a tumor (tumor). There are different types of brain tumors. Brain tumors that arise directly in the brain or begin in the brain are called primary brain tumors. Brain cancer can develop from cancer that first appears elsewhere on the body. Hence the formation of a tumor in the brain is called a secondary brain tumor. It is called a metastatic brain tumor. Primary brain tumors that arise directly in the brain include noncancerous tumors that contain cancer cells and malignant tumors…
Benign brain tumors: Usually, such brain tumors do not grow back after they are removed. Cells in these tumors do not spread to adjacent tissue. Additionally, it does not spread to other bodily regions. But if these tumors are close to them, they can press on parts of the brain and cause serious problems. Sometimes it can be life-threatening.
Malignant Brain Tumors: These tumors contain cancer cells. These are called brain cancer. These cancerous brain tumors are deadly. Cancer cells in these grow very rapidly and invade nearby healthy brain tissue. Cancer cells in these tumors can spread to other parts of the brain or spinal cord. But they rarely spread to other parts of the body.
Symptoms Of Brain Tumor
Symptoms of a brain tumor depend on the size of the tumor, the type of tumor, and the part of the brain where the tumor is located. Some of them are:
- Headache (especially in the morning).
- Nausea, vomiting.
- Differences in speech, vision, hearing, and walking without balance.
- Mood swings and acting strangely, inability to concentrate.
- Having fits.
- Numbness of arms and legs, as if pricked by needles.
- All of these symptoms may not be caused by a brain tumor. It might be brought on by further health issues.
- Memory problems.
Confirmation
When a brain tumor is suspected, the doctor prescribes various tests to confirm it. Some of them are:
Neurological examination:
Is the eyesight good? How is the hearing? Balance in walking would it be good? How is coordination between organs? This is a neurocognitive test of how reflexes work. If any of these are different, it can be predicted in which part of the brain the tumor is.
MRI:
This is an imaging test commonly used to diagnose brain tumors. CT and PET (positron emission tomography) scans are also helpful.
To Detect Cancer In Other parts Of The Body:
When cancer that started in another part of the body seems to have spread to the brain (secondary brain tumor), the doctor uses a CT scan to try to find out from which part. For example, a CT scan of the chest can detect lung cancer.
Biopsy:
A hole is made in the head of the tumor (called a bur hole), a needle is passed in, and with the help of CT or MRI scanning, some tissue is removed from the tumor, and the biopsy is performed. A biopsy will confirm whether the tumor is cancerous or not. Based on that, the treatment is assessed.
Treatment
Treatment for a brain tumor depends on the size of the tumor, the type of tumor, what part of the brain it is in, and what type of treatment the patient prefers.
Surgery
Surgery is the first choice of treatment for brain tumors. Shaving the head before surgery. As part of the surgery, the cow is anesthetized, an incision is made on the skull, and the bone is removed with a special saw. That is called a craniotomy. After the tumor is removed bone, metal, or fabric brought from elsewhere in the body is used to stitch the hole in the skin. After the brain tumor is removed, the patient is asked to lie awake and read numbers, move his leg, move his hand, read the alphabet or say something. The patient will know whether the surgeon has been able to preserve important parts of his brain. If the tumor has spread to the brain stem or some other sensitive part of the brain, it is not possible to remove the tumor without removing the surrounding connective tissue.
In that case, another treatment like radiation therapy should be resorted to. After the surgery, there will be problems like a headache for a few days. They are usually controlled with medication. There is also fatigue and weakness. Steroids work for swelling after swelling and fluid build-up inside the skull. Surgery may be needed to remove the fluid.
Brain surgery can damage normal healthy brain tissue. There is also a risk of brain damage and the inability to think, speak and see. There may be a change in a person’s behavior (personality changes). Fits may occur. Most of these problems can subside or heal over time. As the brain is a very sensitive organ, such accidents are inevitable.
Radiation Therapy
After surgery to remove the tumor, radiation therapy is used to destroy any remaining cancer cells in the tumor. Because of this, side effects like nausea may appear for a few hours after the treatment. Also, the patient may feel completely tired and lethargic. Rest is important. But doctors try to keep the patient active. Another side effect is hair loss. Also, the cow’s skin and ears become red and dry. Doctors prescribe these remedies.
