According to the Central Brain Tumor Registry of the United States (CBTRUS), the incidence rate of all primary malignant and non-malignant brain and central nervous system tumors (CNS) for 2005 to 2009 was 20.6 cases per 100,00 (7.3 per 100,000 for malignant tumors and 13.3 per 100,000 for non-malignant tumors) (Fig. 1) [1].
Figure 1. Average annual incidence rates of primary brain and CNS tumors by age and type of tumor [1].
The incidence rate for children between 0 and 19 years old was 5.13 per 100,000. For adults over 20 years of age, the incidence rate was 26.8 per 100,000. The rate was higher in females (22.3 per 100,000) than males (18.8 per 100,000).
The distribution of the type of brain and CNS tumors is shown in Figure 2.

Non-malignant meningioma was most frequently reported as it accounts for more than a third of all tumors. Glioblastoma was the second most frequent type to be reported followed by tumors of the pituitary.
Brain metastases are a common complication of cancer. The incidence of brain metastases is increasing worldwide [2]. About 160,000 to 170,000 of new cases occur per year in the United States. The most frequent types of cancers that tend to develop brain metastases are lung cancer, breast cancer, and melanoma, which account for 67%-80% of all cancers [3]. The most recent population-based study was conducted by Barnholtz-Sloan et al. [4] who used the Metropolitan Detroit Cancer Surveillance System and found the incidence percentage of brain metastases to be 9.6% between 1973 and 2001. Overall, population-based studies show incidence rates of brain metastases ranging from 8.3 to 14.3 per 100,000 population and 8.5-9.6...

but they are often more aggressive in adults than children. In adults, tumors in the hypothalamus are more likely to be metastatic (resulting form the spread of cancer form another organ to the hypothalamus) than they are when they occur in children. Peter Heage, of Colorado, was diagnosed with a hypothalamic brain tumor. He said that he was having headaches too often,

Radiation therapists work closely with patients to fight cancer. According to Health Care Careers, Oncologists, Dosimetrists and nurses are some of the professionals that a radiation therapist works with while caring for a cancer patient. This group of professionals will determine a specialized treatment plan. The first step usually includes a CT scan performed by a radiologist to find the exact area that needs to be targeted with x-rays. Next, the therapist uses a special machine that emits radiation called a Linear Accelerator. They use this machine during a treatment called external beam therapy. During this process, the Linear Accelerator will project x-rays at targeted cancer cells or tumors. Another therapist will be in a different room monitoring the patient’s viral signs until the procedure is over. The external therapy l...

Due to the brain being protected by the skull, brain tumors have very little room for growth “without pressing on other parts of the brain,” which may cause damage to the nervous system and be life threatening and life altering (Abrahams 120). Some of the possible symptoms to abnormal growths are headaches, intellectual impairment, loss of memory, impaired judgement, confusion, and personality and behavior changes, but on countless occasions the symptoms may go undetected by the carrier (Abrahams

According to SEER Statistics, 23,380 people are estimated to get a brain or nervous system cancer diagnosis. Out of those people, 14,320 people are estimated to die from their brain or nervous system cancer diagnosis (National Cancer Institute). Cancer is a type of dangerous tumor, or a buildup of extra cells that form a mass of tissue, that can be life threatening (National Cancer Institute). The term for a tumor that is cancerous is a malignat tumor, whereas a benign tumor does not contain cancer cells (National Cancer Institute). According to the National Cancer Institute, the causes of brain cancer are unknown, but risk factors include family history and excessive radiaton exposure. Although they are not always due to a brain tumor, comon symptoms include headaches, nausea, speech, hearing, vision, and mood changes, problems with balance and mamories, seizures, and numbness in arms and legs (National Cancer Institute). MRI and CT scans as well as surgical biposies (or the removal of part of the tumor to be examined) are used to diagnose brain cancer (National Cancer Institute). Different types of treatment options include radiation therapy, surgery to remove the tumor, and chemotherapy. According to Charles Davis, MD, PhD and Nitin Tandon, MD of WebMD.com, chemotherapy is “ the use of powerful drugs to kill tumor cells”. There are a few different types of chemotherapy, but all of which bring out the same kinds of side effects. Although the physical side effects of chemotherapy are commonly known, few people know of the emotional toll chemotherapy can take on a patient and his or her family as they go though this process.

Obstructions such as tumors can interrupt normal brain activity, leading to deficits of normal reasoning, motor control, or consciousness. Many of the signs of neural damage are easily recognizable by an outside observer, but since the actual cause of these problems are internal, the symptoms can be vague. The real deficits can affect the brain’s anatomy, or the way signals are processed. A physician can only determine the real cause by examining the brain internally to find irregularities, either in structure or in functioning.

How does one see the symptoms for childhood cancer? First one must know that there are many different types. There are forty different types of children’s cancer, including: Leukemia, Lymphoma, Sarcomas, cancers of the nervous system, liver cancers, kidney cancer, and more. Out of these cancers, the two most common childhood cancers are Leukemia, and brain tumors. What is leukemia? It is a cancer in which the bone marrow and other organs that produce blood produce and increased amount of immature or abnormal white blood cells. The symptoms of leukemia are paleness, excessive bruising, pain in the joints, and fatigue. Brain tumors are formed when a massive amount of cells are produced on the brain. The symptoms for this are frequent headaches, vomiting, seizures, decreased coordination, weakness, and problems concerning vision.
