Brain Tumor : Symptoms, and Causes
Our brain is where everything is. All our thoughts and actions are the products of our brains. So naturally, the idea of a disease that affects the brain is terrible.
Brain cancer is a rare but destructive cancer, accounting for 2% of all cancers in the world. Brain cancer refers to abnormal growth and division of brain cells. Brain tumors can be benign or malignant. Malignant brain tumors are divided into primary brain tumors that originate in the brain and secondary brain tumors that originate in other parts of the body and spread (metastasize) to the brain.
Whether the tumor is benign or malignant, it can increase the size of the brain. This puts pressure on the narrow area of the skull. The skull is very stiff and hard. Intrusion into confined spaces This increases the pressure on the skull. This can cause brain damage, coma, and even death.
Types of brain tumors
The first major classification of brain tumors is benign. Benign brain tumors are the least aggressive and slow-growing tumors. They have no cancer cells and have a good prognosis after treatment.
Malignant or malignant brain tumors originate in brain cells. Support cells and other tissues are found in and around the brain. These are high-grade tumors. Tumor scoring involves assessing growth on a scale of 1 to 4, with low scores 1 and 2 and high scores 3 and 4. Benign tumors are low-grade, slow-growing, existing, and unlikely to spread. And it is unlikely to recur after removal. On the other hand, malignant or malignant tumors are high. This means that they grow very fast. Spread to surrounding tissues and often reappear after removal.
Malignant tumors are divided into primary and secondary tumors.
Early malignant tumors of the brain itself. Secondary tumors are caused by the spread of tumors to other organ systems. often found in the lungs
Primary tumors are rare, and the most common types of primary brain tumors are glioma and meningioma. Glioma affects glial cells, which are the supporting cells in the brain that provide nutrients and structural support for neurons. Gliomas account for 50.% of all primary brain tumors
Brain tumor symptoms
The brain is a large and complex organ. Symptoms of brain tumors depend on the size, type, and location of the tumor. Common signs and symptoms are:
- Headache, which usually worsens in the morning and gradually worsens over time
- Persistent nausea
- Vomiting often
- Progressive weakness
- Unexplained weight loss
- Changes in behavior or mood
- Eye problems
- Confusion and amnesia
- The specific symptoms depend on the size of the tumor and the location of the tumor. From this, some of the signs and symptoms that can be observed are:
- Personality changes are less restraining bad decision-making and other frontal lobe tumors
- Language, memory and hearing impairments of temporal lobe tumors
- Sensory disturbances, progressive muscle weakness in parietal tumors, etc.
- Visual impairment or vision loss of occipital lobe tumors
- Cerebellar tumor loses balance and coordination
- Changes in breathing, blood pressure, and heart rate in brain tumors
The following is a brief summary of tumors in key brain regions. As you study in depth, you may experience various symptoms, from loss of language comprehension to hallucinations.
Causes of brain tumors
The exact cause of brain cancer remains unclear
The two main factors involved in the development of brain tumors are genetics and radiation exposure. Gene mutations, sequence deletions and loss of tumor suppressor genes.. It is thought to cause brain tumors. A family history of melanoma can also increase your risk of developing this disease. Certain genetic diseases, such as neurofibromatosis, tuberous sclerosis, and Turner syndrome, are associated with an increased risk of brain tumors.
Exposure to ionizing radiation has been linked to brain cancer, especially children’s exposure to vinyl chloride, an industrial chemical used in the manufacture of PVC, is also linked to brain cancer.
Other risk factors for brain cancer are:
Age: The risk increases with age. In addition to some forms of brain cancer that are more common in children.
Previous cancer diagnosis: People with cancer in other parts of the body have an increased risk of brain cancer. Especially childhood cancers and blood cancers, such as leukemia and non-Hodgkin’s lymphoma.
HIV/AIDS: People with HIV/AIDS are twice as likely to develop brain cancer as the general population.
Brain tumor treatment
The brain cancer treatment plan depends on the size, grade, and location of the tumor. So is the general health of the patient. Malignant brain tumors are usually removed by surgery. However, due to its location or other factors (such as ease of access), it may not always be possible to remove the entire tumor.
Radiation therapy is another option for treating brain tumors. Radiation damages the DNA of cancer cells. Prevents the division and growth of cancer cells.
Chemotherapy or anti-cancer drugs are not always used because the blood-brain barrier prevents many of these drugs from being transported from the blood to the brain.
Several experimental therapies are still under development.
Early tumor treatment can prevent future complications. 15% of brain cancer patients survive five years or more after diagnosis. Nevertheless, there is hope. The prognosis depends on many factors. Understanding the risks and discovering any suspicious symptoms can help early diagnosis. Wake up for good health
