What Is The Main Cause Of Brain Tumor?

What Is The Main Cause Of Brain Tumor?
There is no trustworthy evidence regarding what causes brain tumors, but there are a few risk factors that have been substantiated through research. Children and young people who receive radiation around the head are susceptible to developing tumors in the brain once they grow up. Also, people with a certain kind of rare genetic condition like neurofibromatosis may develop a brain tumor though such cases are very few in number. Age is also an important factor as people aged over 65 years are diagnosed with brain tumors at quadruple times higher than children and younger people.

Types of Brain Tumours-

A primary brain tumor originates in the brain, and they may or may not be cancerous. Some tumors can be benign, which do not spread in the surrounding tissues and are not very malicious. However, that does not signify that they will not cause any harm over time. Sometimes these tumors can be severe and cause a threat to the life of the sufferer. The National Cancer Institute reports that approximately there were 23, 380 fresh cases of brain tumors in 2014.

Identifying the Symptoms of Brain Tumors-

The symptoms of the brain tumor are dependent on various factors such as the size, type as well as the exact location of the tumor. These symptoms are triggered when any tumor is pressed or clashed against a nerve or disturbs a part of the brain. Symptoms are also felt when any tumor particle blocks the fluid flowing around the brain or when there is a swelling in the brain owing to the build-up of fluid.

Common symptoms include- headaches that get worse in the morning, nausea along with vomiting, an alteration in the speech, hearing and imbalances in walking and movement, mood swings, change in personality and ability to concentrate or remember things and seizures or convulsions.

Treatment for Brain Tumor-

Surgery is normally the most usual treatment for brain tumors, and the patient is given anaesthesia, and the scalp is shaved before the surgery. Then, craniotomy is performed to open the skull, and the surgeon removes a bone piece out of the skull. Then the tumor is removed as much as possible. The bone is then restored back, and the incision on the scalp is closed. Sometimes surgery is not viable in case the tumor has developed in the brain stem or some other complex parts.

Neurosurgeons can surgically remove some tumors completely (called resection or complete removal). If the tumor is near sensitive areas of the brain, neurosurgeons will only be able to remove part of it (called partial removal). Even partial removals can relieve symptoms and facilitate or increase the effectiveness of other treatments.

The role of surgery in treating brain tumors

Surgery can provide:

- The complete removal of some brain tumors
- A sample to enable doctors to diagnosis the tumor and recommend the most appropriate treatment
- Better quality of life:
- Reduced symptoms and improved ability to function (e.g., to think, speak or see better)
- Less pressure within the skull from the tumor
- A longer life

In case you or any of your near ones is affected with brain tumor, you should visit the doctor to know the possible treatments other than surgery and other important questions related to brain tumor.

Brain Tumors - How To Treat It?

Brain Tumors - How To Treat It?
Short course radiation therapy is one of the most talked about subject in recent years and also a fascinating research zone. Hypofractionated radiation therapy is an old concept, but only in recent years with tremendous improvement in radiation therapy delivery technologies, there is a significant visible surge in its applicability in clinical practice. Modern radiation therapy technology is capable of delivering high dose to the target while sparing majority of the adjacent critical structures. Hence, it is possible to deliver a short course of the treatment regimen with a higher dose per fraction without increasing toxicity. In brain tumours, radiosurgery with gamma-knife is considered standard of care in many of the clinical indications such as small meningiomas, acoustic schwannomas, residual low-grade gliomas, AVMs and solitary/ oligo brain metastasis. Gamma-knife radiosurgery is in clinical practice for more than five decades.

There are several prospective and randomized studies (level I evidence) with long-term follow up data supporting the use of radiosurgery in these clinical indications. Other indications of radiosurgery are pituitary tumour, craniopharyngiomas, glomus tumours, chordomas and others. Robotic radiosurgery (CyberKnife ) is precision radiosurgery delivery system and an extension of gamma-knife system. CyberKnife uses the principle of gamma-knife, but with linear accelerator source instead of multiple cobalt sources. CyberKnife is capable of treating all tumours indicated for gamma-knife with similar accuracy.

This modern tool has some additional advantages from gamma-knife, such as:

1) CyberKnife can use fractionated treatment, hence relatively larger tumours can be treated,

2) Require only thermoplastic mask, no need for an invasive frame,

3) Has an inverse planning system, can spare critical structure,

4) There is an intra-fraction correction technology with imaging,

5) There is no need to change the source, hence may be more cost-effective and

6) Can be used to treat extra-cranial tumours also.

CyberKnife has a linear accelerator attached with a robot and is capable of treatment from various coplanar and non-coplanar field arrangements. CyberKnife has sub-millimetre accuracy and unmatched dose distribution.

The advanced technology behind CyberKnife uses image guidance technology and computer-controlled robotics to deliver an extremely precise dose of radiation to targets, avoiding the surrounding healthy tissue, and adjusting for patient and tumor movement during treatment. In conclusion, CyberKnife is an extension of gamma knife radiosurgery delivery system. This machine has immense promise to treat with short-course regimens with high dose and improve local control without increasing toxicities.

I am suffering from headache for one years, I met a neurologist, he said that I have migraine, he suggested me brain ct scan with contrast. In brain ct scan report everything thing is normal. I have a doubt for brain tumor. Can I go for mri test? Or ct scan is enough for detection of brain tumor? please suggest me.

You are over concerned or worried like a hypochondriac. You need to calm your mind and migraine cannot be diagnosed with any tests and it is diagnosed from the history and medicines are useful. If there is tumour could be seen in ct scan a mri is not needed.

What is the symptoms of brain tumor. How can I know which headache is normal or symptoms of brain tumor?

What is the symptoms of brain tumor.
How can I know which headache is normal or symptoms of brain tumor?
Hello . Brain tumor symptoms can vary from severe headache to totally asymptomatic , depending upon which area tumor is there . Normally if the headache is persistent symptom its advisable to go for Ct scan , in which if tumor is there it can be diagnosed.

In Depth About Brain Tumor And Its Treatment!

In Depth About Brain Tumor And Its Treatment!
A tumor is an uncontrolled and abnormal growth of cells. A brain tumor is thus an abnormal growth and multiplication of cells in the brain. The cell growth can also be in areas adjacent to the brain. The brain tumor may

Have its origin in the brain (Primary brain tumor), or
Its origin may be in some other parts or organs of the body, which gradually spreads to the brain (Secondary/metastatic brain tumor).
Not all brain tumors are harmful and life-threatening.

Brain tumors that exist as noncancerous cell growths are known as Benign brain tumors. Benign brain tumors seldom pose any threat to life.

Brain tumors that are cancerous and, thus, harmful, are known as Malignant brain tumors.

Do not neglect any brain tumors (malignant or not). It is better to be safe than to be sorry.

Types of Primary brain tumors:

Based on its cell of origin, primary brain tumors (benign as well as malignant) may be of the following types:

Meningiomas: Brain tumors that originate from the meninges (the membranes that cover the brain and the spinal cord). Meningiomas are seldom malignant.
Acoustic Neuromas: A noncancerous cell growth that has its origin in the vestibulocochlear nerve (the eighth cranial nerve). This nerve connects the brain with the inner ear.
Gliomas: Here, the tumor has its origin in the brain and the spinal cord (glial cells). This type of brain tumors, in most cases (~80%), are malignant.
Primitive Neuroectodermal Tumors (PNETs): Extremely rare, PNETs are malignant tumors that develop in the embryonic cells in the brain.
Medulloblastomas: Medulloblastomas is a malignant brain tumor that mostly affects children. It originates in the cerebellum (lower part of the brain).
Craniopharyngiomas: A benign brain tumor that has its origin near the pituitary gland (base of the brain). Craniopharyngiomas are common in children.
Probability of a secondary brain tumor are more in people who have had;

Kidney cancer
Breast cancer
Lung cancer
Colon cancer

The symptoms of a brain tumor include:

Chronic and regular headaches.
A change in the headache pattern.
A person may experience vision problems (Peripheral vision may be affected, double or blurred vision).
There may be difficulty in hearing.
Nausea and vomiting.
Behavioral and speech problems.
An arm or a leg may lose sensation.
A person has difficulty with balance.
Diagnosis and Treatment:
Though brain tumor can affect anyone and everyone, its chances are higher in

People who are more exposed to ionizing radiation. People having undergone radiation therapy are equally vulnerable.
Children as well as older people.
People having a family history of brain tumors.
The diagnosis includes;

An imaging test like the MRI, CT scan and PET (Positron Emission Tomography).
Biopsy, whereby samples of the abnormal tissue is collected and examined.
Neurological examination.

Surgery is an effective treatment for brain tumors.
One can also opt for:

Radiations, whereby the abnormal tumor cells are destroyed using protons and x-rays (high-energy beams).
Chemotherapy: In this treatment, the tumor cells are destroyed using strong drugs (taken orally or intravenously).
Targeted drug therapy: This treatment blocks the abnormalities that are characteristically present only in the cancer cells.

Tumor - What Are Different Types Of It?

Tumor - What Are Different Types Of It?
A tumor may be defined as an abnormal unwanted growth of tissue in any part of the body. This word need not immediately cause panic because the tumor may or may not cause a health threat. There are three types of tumors:

Benign tumor: This is a noncancerous type of tumor. In our body, new cells are formed while the old ones called dead ones are disposed by our immune system. When this disposal of cells does not occur, the remaining dead cells form a lump, which is called a benign tumor. They are not dangerous since, they do not contain harmful fluids and do not spread. A person suffering from a benign tumor in the brain may have frequent headaches.
Pre-malignant tumor: It is an initial disorder, or an earlier symptom of cancer manifestation. The inclination of this medical condition is that it will progressively become precarious. This is so because it is capable of conquering neighboring tissues and spreading as well. Leukoplakia is a form of premalignant cancer. They evolve as thick white patches inside the cheeks or on gums below the tongue. These patches are very difficult to be scraped off from the mouth. They are caused mainly due to chewing tobacco and smoking, and ff left untreated can expand.
Malignant tumor: These are the cancerous tumors, in which cells multiply abnormally and rapidly. They are unstable and travel along bloodstream, circulatory system and lymphatic system to other parts of the body. Sarcomas and carcinomas are the most common types of malignant tumors. While the former is related to connective tissues the latter is related to organs and glands.
The most common procedure to name the type of cancer is to refer to their site of origin. Adenocarcinoma, refers to cancer in the adenoid glands. Similarly, a benign tumor of fatty tissue is called lipoma, where as a malignant tumor in the same area is referred to as liposarcoma.

What is a biopsy? How does it relate to a tumor?
A Biopsy is a medical procedure practised by qualified medical practitioners. This procedure helps in identifying the type of tumor within a patient. It aids the doctor to conclude the type of treatment to be given to any patient. This procedure is a definite diagnosis to the identification of cancer. A Biopsy is the removal of a sample of the abnormal, unwanted tissue for laboratory examination. Biopsies are of different types, and they may be performed using ultrasound, CT scan or MRI depending on where the tumor is.

Excisional biopsy: In this method the entire lump of excess tissue is removed.
Incisional biopsy: Here a sample of the abnormal tissue is removed surgically.
Needle aspiration biopsy: Here the sample is extracted with the help of a needle.
After extraction, the tissue layers are sent to pathological departments to check their composition, and cause of disease.
