umours in the brain are caused by an expansion of cells, which results in a mass; some are benign or non-cancerous. Brain tumours, whether malignant or not, can cause serious diseases since the skull is inflexible and does not enable the tumour to grow. In addition, if the tumours form near areas of the brain that govern important activities, they may produce symptoms such as weakness, trouble walking, imbalance, partial or total loss of eyesight, difficulties interpreting language, and memory issues.
In layman’s terms, DNA instructs the cells on what to do. This DNA occasionally changes and instructs cells to multiply abnormally, dividing fast and live longer than healthy cells are intended to. These cells aggregate to form a bulk. In numerous areas of the brain in the case of a brain tumour. Since the brain is the body’s primary control system, all other bodily processes are influenced by it.
The mass is made up of aberrant cells that might spread and infect nearby tissues. Depending on how severe they are, these tumours might be categorised as distinct categories of tumours.
These tumours kill brain cells and develop in the brain or nearby tissues. Primary brain tumours are what they are called.
The most typical primary tumours consist of
- Astrocytoma, oligodendrogliomas, glioblastomas, and ependymomas are all types of gliomas.
- Medulloblastomas
- Meningiomas
- Acoustic neuromas
Gliomas account for around 65% of all primary brain tumours.
A secondary or metastatic brain tumour develops when any sort of cancer that is developing elsewhere in the body spreads to the brain. The typical tumours that can spread to the brain include those in the lung, breast, kidney, and colon.
The brain might have a single area affected by metastatic disease from another region of the body, or it can have several areas. Brain cancer can spread to many different cancer kinds. They comprise
- Mammary cancer
- Chest cancer
- renal cancer
- Melanoma
- Thyrotoxic cancer
- Leukaemia and lymphoma
Benign brain tumours are non-cancerous tumours that are easily treatable. They might be deadly if they start to cause issues in certain regions of the brain.
Cancerous tumours, such as malignant brain tumours, have the potential to spread to the nearby healthy tissues.
According to the rate of malignant cell development and their capacity to produce symptoms, brain tumours vary.
- Brain tumours are categorised into distinct categories based on how quickly their cells are proliferating and spreading:
The greater the number, the more severe the tumour: Brain tumours of grade 1 and 2 are non-cancerous (benign) tumours that develop slowly.
Brain tumours in grades 3 and 4 are cancerous (malignant) tumours that develop fast and are more difficult to cure.
Grade I: In this scenario, the tissue is benign. Growth is sluggish, and cells seem normal when closely examined.
Grade II: The cells are not as normal as they appear in Grade II, and the tissue is cancerous.
Grade III: Cancerous cells grow rapidly and are referred to as anaplastic. Another distinguishing trait is that the cells emerge in the opposite direction of healthy cells.
Grade IV: The cancerous tissue contains destructively aberrant cells that proliferate more quickly. Their expansion is pretty rapid.
The Implications of Brain Tumours
tumours are dangerous:
- They target and damage brain tissue.
- They provide pressure on neighbouring tissue.
- Because the tumour takes up space and the skull cannot grow to accommodate it, they increase pressure within the skull (intracranial pressure).
- Tumours cause fluid to accumulate in the brain.
- They hinder the natural circulation of cerebrospinal fluid through the brain’s spaces. These spaces increase in response.
- Tumours can result in bleeding.
Brain Tumour Treatment Options
Brain tumour treatment in India include the following:
- Craniotomy is a type of brain surgery.
- Shunts, radiosurgery, and stereotactic procedures
A Brain Tumour’s Causes
Although there are no specific causes of brain tumours, there are certain common risk factors or triggers that may result in a brain tumour:
- Obesity and being overweight increase the chance of developing some forms of brain tumours.
- Tobacco use and excessive alcohol use contribute to an unhealthy lifestyle that may only result in aberrant cell development.
- The chance of developing brain tumours increases with age.
- Ionising radiation, X-rays, and computed tomography (CT) scans, as well as power lines, nuclear reactors, mobile phones, and cell phone towers, can all cause tumours.
- Certain toxic substances, such as diesel exhaust, coal tar volatiles, cigarette smoke, arsenic compounds, cadmium compounds, nickel compounds, and others, may cause a brain tumour.
- Childhood cancers, such as leukaemia, increase the chance of developing brain tumours as an adult. Adults who have had cancer may also be at risk of developing brain tumours; however, additional study is needed to corroborate this conclusion.
- In rare circumstances, brain tumours may be inherited genetically.
The Price of Brain Tumour Surgery
In India, the average cost of Brain Tumour surgery is $4800. This is around 20% of what it costs in Western countries, where the average cost of Brain Tumour surgery is reported to be more than $25,000.
The cost may differ from case to case and from person to person. In the case of brain tumours, there are several aspects that influence price.
The categorization of Tumour
- The tumor’s stage and grade.
- Utilisation of technology.
- The type of surgery that was done.
- The total number of radiation cycles.
- Medicine and other consumables are expensive.
- The overall length of a hospital stay.
Surviving Brain Surgery Possibilities
- Typically, the survival rate is a 5-year survival rate.
- This represents the proportion of persons who will live over the following five years after being diagnosed.
- Survival rates often estimate outcomes based on persons who have previously experienced the condition, which may or may not be related to what happens subsequently.
- Men and women have different 5-year survival rates for brain tumours.
- Men’s Brain Tumour Survival Rate is 34%.
- Women with brain tumours had a 36% chance of survival.
- However, survival rates vary based on a variety of different factors, with the most frequent being tumour kind, age, and so on.
- A brain tumour requires surgical therapy to eliminate tumours, which is performed by a team of highly skilled surgeons.
Success Rate of Brain Tumour Removal
When neurosurgeons remove a benign or malignant tumour of the brain from the patient’s brain, it is a complicated procedure.
The procedure is most commonly used to treat benign neoplasms such as meningiomas.
The tumour is also excised in order to-
- Glioma.
- Glioblastoma.
- Astrocytoma.
The success rate of surgical excision of a brain tumour is dependent on a number of factors.
- In general, surgical removal is the most successful therapy. More than 85% of patients survive for 5 years with early therapy.
- In late-stage malignancies, when the tumour is big and cannot be removed surgically, the chances of survival decline to 40%.

It is also a restricted choice since if one criteria is not satisfied, another therapy is chosen.
- The procedure is only conducted if and only if the following conditions are met:
- The tumour is modest and well-defined.
- The neoplasm spreads quickly.
- The tumour does not affect any essential areas of the brain.
- The neoplasm is in an area that the surgeon can reach.
The surgery takes 4 to 6 hours since it demands tremendous precision and attention.
Success Rate of Brain Tumour Surgery
The success rate of brain tumour surgery is totally dependent on the tumour’s stage, size, and kind, as well as the patient’s age, gender, and so on.
A basic rule governs the success rate of brain tumour surgery:
- The sooner a patient receives therapy, the less obvious the operation’s results.
- During the early stages of cancer, if the procedure has no problems, the patient will almost certainly return to a normal and active life.
- However, if the tumour has impaired any of the brain functions, the patient may need to undergo neurological rehabilitation.
Keep an eye out for early warning signs that should not be ignored:
- Vomiting/nausea for no apparent reason.
- Double vision or blurred vision.
- Fatigue.
- Sleepiness has increased.
- Seizures begin.
- Headaches, particularly in the morning.
- Memory issues.
- Speech impediment.
