Brain Tumors in Adults

What Is a Tumor?

A tumor is a mass of tissue that's formed by an accumulation of abnormal cells. Normally, the cells in your body age, die, and are replaced by new cells. With cancer and other tumors, something disrupts this cycle. Tumor cells grow, even though the body does not need them, and unlike normal old cells, they don't die. As this process goes on, the tumor continues to grow as more and more cells are added to the mass.

Primary brain tumors emerge from the various cells that make up the brain and central nervous system and are named for the kind of cell in which they first form. The most common types of adult brain tumors are gliomas and astrocytic tumors. These tumors form from astrocytes and other types of glial cells, which are cells that help keep nerves healthy.

The second most common type of adult brain tumors are meningeal tumors. These form in the meninges, the thin layer of tissue that covers the brain and spinal cord.

What Are the Symptoms of a Brain Tumor in Adults?

Symptoms of brain tumors vary according to the type of tumor and the location. Because different areas of the brain control different functions of the body, where the tumor lies affects the way symptoms are manifested.

Some tumors have no symptoms until they are quite large and then cause a serious, rapid decline in health. Other tumors may have symptoms that develop slowly.

A common initial symptom of a brain tumor is headaches. Often, they don't respond to the usual headache remedies. Keep in mind that most headaches are unrelated to brain tumors.

Other symptoms include:

Seizures
Changes in speech or hearing
Changes in vision
Balance problems
Problems with walking
Numbness or tingling in the arms or legs
Problems with memory
Personality changes
Inability to concentrate
Weakness in one part of the body

It's important to keep in mind that these symptoms can be caused by a number of different conditions. Don't assume you have a brain tumor just because you experience some of them. Check with your doctor.

How Are Brain Tumors Diagnosed?

To diagnose a brain tumor, the doctor starts by asking questions about your symptoms and taking a personal and family health history. Then he or she performs a physical exam, including a neurological exam. If there's reason to suspect a brain tumor, the doctor may request one or more of the following tests:

Imaging studies such as a CT(CAT) scan or MRI to see detailed images of the brain
Angiogram or MRA, which involve the use of dye and X-rays of blood vessels in the brain to look for signs of a tumor or abnormal blood vessels

The doctor may also ask for a biopsy to determine whether or not the tumor is cancer. A tissue sample is removed from the brain either during surgery to remove the tumor or with a needle inserted through a small hole drilled into the skull before treatment is started. The sample is then sent to a lab for testing.

How Are Brain Tumors Treated?

Surgery to remove the tumor is typically the first option once a brain tumor has been diagnosed. However, some tumors can't be surgically removed because of their location in the brain. In those cases, chemotherapy and radiation therapy are both options for killing and shrinking the tumor. Sometimes, chemotherapy or radiation is also used after surgery to kill any remaining cancer cells. Tumors that are deep in the brain or in areas that are difficult reach may be treated with Gamma Knife therapy, which is a form of highly focused radiation therapy.

Because treatment for cancer also can damage healthy tissue, it's important to discuss possible side and long-term effects of whatever treatment is being used with your doctor. The doctor can explain the risk and the possibility of losing certain faculties. The doctor can also explain the importance of planning for rehabilitation following treatment. Rehabilitation could involve working with several different therapists, such as:

Physical therapist to regain strength and balance
Speech therapist to address problems with speaking, expressing thoughts, or swallowing
Occupational therapist to help manage daily activities such as using the bathroom, bathing, and dressing

Obama signs order to cut travel, cellphones, swag

WASHINGTON (AP) — With the stroke of his pen, President Barack Obama has sacked souvenirs federal agencies buy with taxpayer money to promote their work. The ban he signed Wednesday is part of a broader executive order to cut some $4 billion of dollars in waste and make government more efficient. Some office equipment will simply be scarcer, and fewer cell phones and laptops will be issued. Obama has been using his executive powers on modest proposals — Wednesday's order targets trinkets like coffee cups, T-shirts and pens — to promote job creation, help homeowners or, in this case, redirect spending. With such orders, signed in Oval Office ceremonies, Obama is trying to demonstrate that he is engaged in measures large and small and to distinguish himself from what he argues is a pretty unproductive Congress. Lawmakers are in the middle of a more gargantuan task — cutting deficits by at least $1.5 trillion over the next 10 years. "It doesn't replace the importance of work the Congress needs to do in coming up with a balanced, bold plan to reduce our deficit," Obama said as he prepared to sign his administrative order. "But it indicates once again that there are things that we can do right now that will actually deliver better government, more efficiently, more consumer friendly for less money." The saved money won't directly reduce deficits, however. In a statement in advance of the signing, Obama said, "We're cutting what we don't need so that we can invest in what we do need." An administration official said the savings of about $4 billion would allow the administration to focus resources on veterans, members of the military and on infrastructure. The order directs government agencies not only to reduce the authorizations for technology equipment, but also requires cutting the size of the executive vehicle fleet. It also encourages agencies to use technology to save money, including teleconferences and online seminars to reduce travel and online publishing to cut down on publication costs. Overall, the president aims to cut spending in the areas mentioned in the order by 20 percent. "We believe we can get better results for less using technology," Obama said. Vice President Joe Biden and White House budget director Jacob Lew attended the signing in the Oval Office. Obama was also accompanied by four finalists in a cost-saving contest among federal government employees. One finalist suggested the creation of a tool "lending library," another proposed ending the purchase of U.S. code books that are already available online. Among examples cited by the White House of cost-cutting already under way are the Internal Revenue Service's plan to cut 27 percent of its travel costs by relying more on teleconferences and webinars and the Homeland Security Department's decision to conduct annual audits to reduce the number of unused cellphones and air cards. At the Commerce Department, the White House said, the agency has reduced the number of fleet drivers to one for all top departmental officials, including for new Secretary John Bryson.

Heavy D dies at 44

LOS ANGELES (Reuters) - Rapper Heavy D, who rose to fame during the 1990s and scored hit singles such as "Now That We Found Love", died on Tuesday after collapsing outside his Beverly Hills home. He was 44. Beverly Hills Police Lt. Mark Rosen said in a statement that the rapper, whose real name is Dwight Arrington Meyers, was found on a walkway at 11:25 a.m. PST outside his condominium. He conscious and talking, but having difficulty breathing. Paramedics were called and the singer was rushed to a nearby hospital. "The individual ultimately died at the hospital," Rosen said. He added that there were no signs of foul play, and the death is believed to be medically related. An official cause is pending an autopsy by Los Angeles County coroners. The singer's New York-based agent was not immediately available for comment. Rotund rapper Heavy D was born in Jamaica and moved to Mt. Vernon, New York as a child. He enjoyed hip hop music as a kid and formed his first group, the Boyz, with high school friends who took the stage names DJ Eddie F, Trouble T-Roy and G-Wiz. The group became Heavy D & The Boyz and released their first album in 1987, which included singles "Mr. Big Stuff" and "The Overweight Lover's in the House." Their breakout album came with 1989's "Big Tyme," which included the hits "Somebody for Me" and "We Got Our Own Thang." The band met with tragedy in 1990 when Trouble T-Roy died in an accident. One year later, they scored their biggest hit with the album "Peaceful Journey" and single "Now That We Found Love," which reached the top five on R&B charts and crossed over to mainstream pop audiences. A string of hits followed in the 1990s. The band sang the theme song for popular TV show "In Living Color," and Heavy D's 1999 CD "Heavy" became his seventh album to chart among the R&B top 10. During those years, the rapper also began acting, working in small roles on film and TV before landing a role in high-school TV drama "Boston Public". His film work included parts in "The Cider House Rules," "Step Up" and "Big Trouble."

Eddie Murphy quits Oscars after Brett Ratner exit

Actor and comedian Eddie Murphy has resigned as host of the 2012 Oscar ceremony, due to be held in February. His decision comes a day after the resignation of producer Brett Ratner, a friend of Murphy, who used a derogatory term in public. Mr Ratner used the word "fags" during a question and answer session on his latest film Tower Heist. Mr Ratner recruited Murphy to be the Oscars' next host when he was hired as producer of the 2012 awards ceremony. The Rush Hour director has been replaced by Brian Grazer, the Oscar-winning producer of A Beautiful Mind - and frequent producing partner of director Ron Howard. "Brian Grazer is a renowned filmmaker who over the past 25 years has produced a diverse and extraordinary body of work," said Academy President Tom Sherak. "He will certainly bring his tremendous talent, creativity and relationships to the Oscars.' No replacement has been announced for Murphy. Ratings push Correspondents say the comedian's resignation could be a setback for the Academy Awards. The ceremony has seen declining TV ratings in recent years and is battling the rise of newer awards ceremonies, which appeal to younger audiences. Choosing Murphy to host for the 2012 ceremony marked a return to the traditional, well-tried formula of a comedian host - one very successful ceremony was hosted by Bob Hope, Johnny Carson and Billy Crystal. Oscar officials and Eddie Murphy himself insisted the split was not an acrimonious one. "I appreciate how Eddie feels about losing his creative partner, Brett Ratner, and we all wish him well," Sherak said of Murphy's decision to step down. Murphy said: "I was truly looking forward to being a part of the show that our production team and writers were just starting to develop, but I'm sure that the new production team and host will do an equally great job." An online campaign to replace Murphy with the Muppets was initiated on Wednesday.
