An abnormal growth of cells in the brain is called brain tumor …
Brain tumor is a collection of abnormal cells in your brain. There are two types of brain tumor occurs in your brain – cancerous or malignant and noncancerous or benign. These tumors can cause the pressure inside your skull to increase, and can cause brain damage.
Types of brain tumors :
Brain tumors are categorized in two parts –
- Primary brain tumor
- Secondary brain tumor
Primary Brain Tumors :
Primary brain tumors are start within your brain. This tumor can be malignant or benign.
They can occurs from your :-
- Nerve cells
- Brain cells
Gliomas tumor is the most common types of brain tumors in adults, that develop from different types of glial cells. This cell helps to :
- Clean nervous system
- Support the structure of central nervous system
- Provide nutrition to central the cellular waste
- Break down the dead neurons
Types of tumors in glial cells are :
- Oligodendroglial tumor ( found in the frontal temporal lobes ).
- Astrocytic tumor like – Astrocytomas ( originate in the cerebrum ).
- Glioblastomas ( originate in supportive brain tissue ).
Some others primary brain tumor :
- Meningiomas, which originate in the meninges. Generally, it occurs that people whose age is between 40 to 70. ( mostly occurs in women )
- Schwannomas, which originate in cells that produce the protective cover of your nerves. Generally, it occurs that people whose age is between 40 to 70. ( It occurs equally in both gender ).
- pineal gland tumors, which is either benign or malignant
Secondary Brain Tumors :
Secondary brain tumor, also called metastatic brain tumor, occurs when cancer cells spread to your brain from another organ, such as –
Skin Cancer :
Skin Cancer are cancers in which an uncontrolled growth of abnormal skin cells takes place. These abnormal cells have the ability to spread to other body parts. Skin Cancer globally account alone for at least 40% of the cases found. In general skin cancer can be categorized in two broad types known as Melanoma and Non Melanoma Skin Cancer (NMSC).
Breast Cancer :
Breast Cancer starts when breast cells begin to grow out of control. It is the result of mutation of the genes responsible for the growth and health of the cells in the body. This abnormal proliferation in breast cells is called Breast Cancer. Breast Cancer cells may continue dividing without a halt resulting in a tumor that can often be seen on an x- ray or felt as a lump. It is common to women but men are also susceptible to this cancer.
Colon Cancer :
Colon Cancer is the development of cancer in colon (large intestine), the lower part of digestive system. While rectal cancer is the development of cancer in the last part of your colon. Together they both are called Colorectal Cancer. A colorectal cancer is a malignant tumor arising from inner wall of large intestine. It is also known as Bowel Cancer or Colon Cancer.
Risk Factors :-
Factors that may raise a person’s risk of developing a brain tumors are :
According to a survey, most types of brain tumors increases with age. Generally, its more common in children and older adults, although people of any age can affected by brain tumors.
Generally, brain tumor are developed in men are more than women. However, some specific types of brain tumors, like- meningioma, are common in women.
5% to 10% of brain tumors are genetically inherited, or hereditary.
Exposure to virus, allergy and infection :
Electromagnetic Field :
Electromagnetic field, such as energy from power lines or from cell phone use, show no link to an increased risk of developing a brain tumor in adults and children.
Ionizing Radiation :
In some cases, ionizing radiation, including x–rays, may be a risk factor for a brain tumor.
exposure to nerve agents :
According to a survey, some Gulf War veterans have an increased risk of a brain tumors from exposure to nerve agents.
Sign & Symptoms :
There are two types of symptoms of a brain tumors,
- General symptom
- Specific symptom
General symptoms :
General symptoms occurs due to the pressure of the tumor on your brain or spinal cord. Its symptoms are :
- Headache, worse in the morning when waking up
- Loss of control of body functions
- Seizures (especially in adults)
- Nausea or vomiting
- Sleep problems
- Eye problems
- Memory loss
Specific Symptoms :
Specific symptoms occurs when a specific part of the brain is not working well because of the tumor.
- Blurred vision or double vision
- Hearing problem
- Headache near the tumor
- Loss of balance and difficulty with fine motor skills is linked with a tumor in the cerebellum.
