Until now, cancer is still one of the most deadly types of diseases and one of the most feared of brain cancer. Although quite rare, according to WHO this case has grown to around 22,000 people every year with a high mortality rate, which is about 13,000 deaths.
Brain cancer occurs when there is a malignant tumor that attacks the part of the brain and spread so quickly to other parts of the brain. Although the immediate cause is unknown, there are several factors that potentially increase the risk of brain cancer. Such as unhealthy lifestyles, accidents, radiation, exposure to chemicals, and heredity.
Symptoms of brain cancer also depend on several factors, generally that is often experienced by the headaches are increasingly becoming from day to day, numbness, seizures, impaired vision, speech problems, behavior changes, and so forth.
Symptoms of Brain Cancer Generally
Symptoms of brain cancer may vary depending on the size and part of the brain that is infected with the tumor. For example, an optic nerve disorder caused by a tumor will cause visual impairment, and motor neuron disorders will cause the sufferer to experience numbness or difficulty speaking. Here are some commonly recognizable features and symptoms of brain cancer:
- A headache.
- Nausea and vomiting.
- Impaired vision.
- Decreased motor skills.
- Difficulty speaking.
- Cognitive impairment.
- Personality disorder.
- Hormonal disorders.
Symptoms of Brain Cancer Suitable Type
Astrocytoma is a neoplasm that originates and develops from a star-shaped cell called astrocytes. This type of brain tumor can occur anywhere in the brain and spinal cord, but is most common in the cerebrum or cerebrum.
Astrocytoma is classified according to several types or grades, among others, as follows:
- Grade I: Pilocytic Astrocytoma. These tumors have slow growth and rarely spread to surrounding tissues. Generally occurs in children and adolescents and can be cured completely.
- Grade II: Astrocytoma of Difusa. Tumors that grow slowly but can spread to surrounding tissues. Many attack teenagers or young adults.
- Grade III: Anaplastic Astrocytoma. Also referred to as malignant astrocytoma. It can grow rapidly and spread to surrounding tissues. The average affects adults and most sufferers aged 41 years and over.
- Grade IV: Glioblastoma multiforme. These tumors can grow and spread aggressively. Attacking adults aged between 50 and 70 years. It is the most common primary brain cancer (including 50% of primary brain tumors), and one of the primary brain tumors with a very poor prognosis.
- Glioma Brain Stem. A tumor located in the brain stem, at the very bottom of the brain that connects the brain and spinal cord. The brain stem controls many vital functions, such as body temperature, blood pressure, respiration, hunger, and thirst. Tumors in this area can be difficult to treat and most cases occur in children.
The most common symptoms of brain cancer are a headache, nausea and vomiting, seizures, visual impairment, mental disorders, cognitive impairment, and unexplained weight loss.
2. Glioblastoma Multiforme
Glioblastoma multiforme is a grade IV brain tumor of astrocytoma that can grow and spread aggressively throughout the central nervous system (brain and spinal cord). Glioblastoma can appear in every lobe of the brain, but more often develops in the frontal and temporal lobes. Generally, this tumor attacks adults aged 50 years and over.
Symptoms of this type of brain cancer vary, depending on the location where the tumor is located. But most people will experience persistent headaches, blurred vision, nausea, vomiting, loss of appetite, personality changes and decreased intellectual function, and convulsions.
3. Other Gliomas
In addition to astrocytoma, there are a number of other primary brain cancers that can occur at any age and about the brain and spinal cord, including:
It is a glial tumor derived from ependymal cells in the central nervous system (CNS). Most commonly affects children and adolescents. The characteristics of brain cancer Ependymoma is generally like, headache, vomiting, double sight, and head tilt.
Rare tumors that develop in glial cells or oligodendrocyte. These cells produce a myelin sheath that has many layers of fat to protect the nerves in the brain and spinal cord. These tumors are very rare, the growth is slow and generally does not spread to the surrounding brain tissue. Most common in middle-aged adults. Generally, bring a better prognosis when compared with astrocytoma. Symptoms of oligodendroglioma brain cancer include a headache, seizures, behavioral changes, and cognitive impairment and motor function.
It has two types of tumor cells, oligodendrocyte, and astrocytes. This type of brain tumor is most commonly formed in the cerebrum or cerebrum. The symptoms or characteristics of this brain cancer are a headache and nausea which are usually the result of increased pressure in the brain and impaired vision, as well as behavioral changes.
4. Other Brain Tumors
Tumors that appear on the protective membranes of the brain and spinal cord (meninges) and are usually benign (non-cancerous). Growth tends to be very slow, most common in women aged 30 to 50 years. The main symptoms of brain tumor are meningioma ie, arms and legs felt weakness, convulsions, numbness, and headaches worse.
Tumors that appear in the pituitary gland. Generally, these tumors are benign and divided into two types according to size, macroadenomas (measuring more than 1 cm) and microadenoma (less than 1 cm in size). Symptoms such as fatigue, irregular menstruation, sudden weight loss, and more. Generally affects adults between the ages of 30-50 years.
Brain tumor located in the hypothalamus area above sella tunica. Although generally benign, sometimes this brain tumor can become malignant because it can cause pressure and damage to the hypothalamus that serves to control body temperature, hunger, and thirst. This tumor is most common in children and adolescents, or adults over 50 years of age. Symptoms such as a headache, nausea, and vomiting in the morning due to increased pressure in the brain, excessive thirst, and frequent urination.
Germ Cell Tumors
Tumors that grow on reproductive cells (egg or sperm cells), also known as germ cell tumors. One type is germinoma. In addition to the brain, germinomas can also form in the ovaries, testicles, chest, and abdomen. Most of these tumors occur in children and will show symptoms such as abdominal pain, excess body hair growth, entering puberty too early and frequent urination.
Pineal Gland Tumor
Tumors that grow around the pineal gland, the glands that produce the hormone melatonin that plays an important role in the sleeping and waking cycle of a person. The types are divided into two, namely, pineocytoma (slow growth) and pineoblastoma (rapid growth). It takes a high level of surgical skills to remove this tumor, considering the pineal region is very difficult to reach. The typical symptoms of this brain tumor are, the inability to look up.
Tumors are nested and grow rapidly in the cerebellum, the part of the brain that controls physical movement, balance, and speech. Generally, these tumors occur in children or adolescents. Symptoms most often are seen in children such as often dizziness, vomiting, to fainting.
Primary CNS Lymphoma
One type of primary cancer that develops in the lymph nodes to attack the brain or spinal cord. This type of brain tumor is usually found in people whose immune systems are compromised, such as people with HIV. Symptoms such as, speech disorders (aphasia), difficulty swallowing, hearing loss, seizures, and decreased consciousness to coma.
Those are some of the symptoms or characteristics of brain cancer that can be recognized, from the common to the type of each brain cancer. If you have one or more of the characteristics of brain cancer as above (especially headaches painful in the vomiting accompaniment) immediately consult a doctor. If necessary do a support such as CT-Scan or MRI. The sooner known, the treatment of cancer will be more effective.
