Symptoms
A brain tumor is a mass or growth that occurs in the brain. The tumor can be cancerous or noncancerous. Brain tumors can be classified by the type of tissue from which they originate.
The main parts of the brain are the cerebrum, the cerebellum, and the brain stem. The cerebrum is the largest part of the brain and is divided into two hemispheres. The cerebellum is located at the back of the brain and is responsible for movement and coordination. The brain stem is located at the base of the brain and controls many of the body’s automatic functions, such as breathing and heart rate.
Brain tumors can cause a variety of symptoms, depending on their location and size. Symptoms can include headaches, seizures, changes in vision, balance problems, and numbness or weakness in the arms or legs.
A. Cerebrum:
The cerebrum is the largest part of the brain. It is responsible for most of the brain’s functions, such as thinking, learning, and remembering. The cerebrum is divided into two halves, called the left and right hemispheres.
B. Left Hemisphere: The left hemisphere is responsible for most of the brain’s functions that involve language, such as speaking and understanding words. It also controls the muscles on the right side of the body.
C. Right Hemisphere: The right hemisphere is responsible for most of the brain’s functions that involve spatial abilities, such as seeing objects in three dimensions and being able to navigate through space. It also controls the muscles on the left side of the body.
B. Cerebellum:
The cerebellum is a part of the brain that controls movement. It helps to ensure that movements are smooth and coordinated. The cerebellum also helps to maintain balance and posture.
C. Brain Stem:
The brain stem is a part of the brain that is responsible for many basic functions of the body, such as breathing and heart rate. It is located at the base of the brain, and is connected to the spinal cord. The brain stem controls many automatic functions of the body, such as blood pressure and digestion. It also coordinates movement and balance, and transmits messages between the brain and the rest of the body.
Brain Diseases
Brain diseases are a group of disorders that affect the brain. They can cause a wide range of symptoms, depending on the part of the brain that is affected. Some common brain diseases include Alzheimer’s disease, Parkinson’s disease, and stroke.
About Tumour
A tumour is an abnormal mass of tissue. It may be cancerous (malignant) or non-cancerous (benign). Tumours can form anywhere in the body.
A. Primary brain Tumour:
A primary brain tumour is a mass or lump that starts in the brain. It is not cancer that has spread from another part of the body to the brain. There are many different types of primary brain tumours, and they can occur in any part of the brain.
Symptoms of a primary brain tumour depend on the size and location of the tumour. They can include headaches, seizures, changes in vision or speech, problems with balance or coordination, and changes in mood or behaviour.
Most primary brain tumours are not cancerous (benign), but some are cancerous (malignant). Malignant brain tumours are more likely to spread to other parts of the brain or body, and they are usually more difficult to treat.
Treatment for a primary brain tumour depends on the type and size of the tumour, as well as the patient’s age and health. Treatment options may include surgery, radiation therapy, and chemotherapy.
B. Secondary Brain Tumour:
A secondary brain tumour is a cancer that has spread to the brain from another part of the body. The most common types of cancer that spread to the brain are lung cancer, breast cancer, and melanoma (a type of skin cancer).
Symptoms of a secondary brain tumour can vary depending on the size and location of the tumour. Common symptoms include headaches, seizures, nausea, vomiting, and changes in mood or behaviour.
If you are experiencing any of these symptoms, please see your doctor.
Symptoms of Brain Tumour
The symptoms of a brain tumour vary depending on the size, location and type of tumour. However, some of the most common symptoms include:
headache
seizures
nausea and vomiting
changes in mood or behaviour
vision problems
changes in speech
tingling or weakness in the arms or legs
loss of balance or coordination
Symptoms of a brain tumour can also be caused by other conditions, so it is important to see a doctor if you are experiencing any of these symptoms.
Treatment of Brain Tumour
There is no known cure for brain tumours. Treatment is aimed at relieving symptoms and prolonging life. Treatment may include:
Surgery to remove the tumour
Chemotherapy to kill cancer cells
Radiation therapy to kill cancer cells
Brain surgery is a complex and high-risk procedure. It is usually only performed as a last resort, when other treatments have failed.
