What Do You Know About Brain Tumor?

Explanation
A brain tumor occurs when abnormal cells form within the brain. These cells multiply rapidly and form a mass or growth. Brain tumors can be either benign (non-cancerous) or malignant (cancerous). They can cause various symptoms depending on their location and size, such as headaches, seizures, changes in vision or hearing, and difficulty with movement or coordination. Treatment options for brain tumors may include surgery, radiation therapy, chemotherapy, or a combination of these approaches.

Explanation
Cancerous tumors can be divided into two parts. This is because cancerous tumors are typically classified as either benign or malignant. Benign tumors are non-cancerous and do not spread to other parts of the body, while malignant tumors are cancerous and have the potential to invade nearby tissues and spread to other parts of the body through a process called metastasis. Therefore, the correct answer is two.

Explanation
The given statement states that the average five-year survival rate for all brain cancer in the United States is 33%. This means that out of all the people diagnosed with brain cancer, approximately 33% of them survive for at least five years after diagnosis. This statistic provides an insight into the overall prognosis and survival rate for brain cancer patients in the United States.

Explanation
The given question asks about the number of types of major cancers. The answer is 2 because there are two broad categories of major cancers: solid tumors and hematologic malignancies. Solid tumors refer to cancers that develop in organs or tissues, while hematologic malignancies are cancers that affect the blood, bone marrow, and lymphatic system. Therefore, the correct answer is 2.

Explanation
Australia has the greatest average lifetime economic cost of a case of brain cancer, which is $1.9 million. This means that treating brain cancer in Australia is more expensive compared to the other countries mentioned (Nigeria, China, and USA). The high cost could be due to various factors such as the availability of advanced medical technologies, the cost of healthcare services, and the overall healthcare system in Australia.

Explanation
The brain is divided into four lobes: the frontal lobe, parietal lobe, temporal lobe, and occipital lobe. Each lobe is responsible for different functions. The frontal lobe is involved in decision-making and problem-solving, the parietal lobe is responsible for processing sensory information, the temporal lobe is involved in memory and language processing, and the occipital lobe is responsible for visual processing.

Explanation
Personality changes can have a damaging effect such as unemployment. This is because being unemployed can lead to feelings of worthlessness, lack of purpose, and financial instability, which can greatly impact a person's self-esteem and overall well-being. It can also result in increased stress, anxiety, and even depression, which can further contribute to negative changes in personality. Additionally, unemployment can strain relationships, as it may lead to conflicts related to financial burdens and decreased satisfaction in life. Overall, the experience of unemployment can significantly alter a person's personality and have detrimental effects on various aspects of their life.

Explanation
The World Health Organization (WHO) classified mobile phone radiation on the IARC scale into Group 2B - possibly carcinogenic. This means that there is limited evidence suggesting that mobile phone radiation may be linked to an increased risk of cancer. The WHO's classification highlights the need for further research and precautionary measures to ensure the safety of mobile phone use.

Explanation
The correct answer is Two. This suggests that there are two areas composed of broad classes of cells.

Explanation
The correct answer is USA because the question states that there are about 170,000 new cases every year, but it does not specify what type of cases are being referred to. However, considering the high population and healthcare system in the USA, it is reasonable to assume that the number of new cases would be higher compared to the other countries listed.
