Small wireless device that has at least the equal functions of a normal wired telephone, but is smaller and more mobile. A cell phone requires a subscription from a service provider and requires either a prepaid or monthly billing setup. Generally, they have more functions than traditional landlines phones and need to be charged after a certain period of time also called mobile phone or mobile device. Portable telephone device does not require the use of landlines. Mobile phones make the most of frequencies transmit by cellular towers to connect the calls between two wireless devices. For example, I call my friend by using a cellular phone; "If the bus is late, I will cell phone you"

The history of cell phones is based upon radio technology and that was developed from the 1940's forward. For instance, the cell phones can be traced to the originality in taxi cabs, police cars and other service vehicles where two way radios were used to talk with one another or with a central base. The first mobile phone was used in Sweden by the Swedish police in 1946. The technology was connected to the telephone network and was created of two way radio technology. While the technology had been developed, it was not until 1971 that AT&T submitted an application to the Federal Communications Commission (FCC) for cell phone service. It took more than 10 years for an approval by FCC. In 1982, the FCC allocated the frequencies of 824-894 megahertz (MHZ). The first mobile phone was created by Motorola, Inc. Mobile phones have developed to be the most widely used portable device in the world. Mobile phones may also be referred as wireless or cell phones. Today, AT&T is the worldwide services provider and one of the largest cell phones company in the world.

Cell phones and a household cordless phone use a low level of microwave radiation to send and receive their signals.  As we all know that, microwaves are used to cook food.

There are different reasons that Cell phones are dangerous: They produce microwaves, you hold the source of the let go against your brain, and there are claims that people have had brain tumors in the exact size, shape and spot as the antenna on their cell phone. There are different reasons that Cell phones are safe: Cell phones use a very low level of radio frequency (RF) energy too low to cause damage, the type of energy produce is non-ionizing meaning it doesn't cause damage to chemical bonds or DNA in the body.

Like computer, television, alarm system, and all other electrical devices, cell phones (also called mobile phones) are radio devices that use radiofrequency. In 1993, first case was file against cell phone Company by a man who claim his wife brain tumor was cause by a cell phone use. Resulting, the cell phone company funds $25 millions studies to prove that cell phone was safe. They hired Dr. George Carlo a highly respected public health scientists to conduct a research. Dr. Carlo proved the opposite of what the cell phones company wanted. Brain cancer is up by 25% since the cell phone become popular. Neurosurgery believed radiation from cell phones and other mobile device are directly related 21% increase in brain tumors in children. Dr. Sheldon levy respected physician and surgeon has studies the effect of radiation. The data show that the certain body organs are particular sensitive to this thermal effect or heat generated by invisible microwave such as stomach, intestine, and bladder are especially sensitive to thermal damage of high level of microwave electromagnetic Spectrum and electromagnetic radiation. The testical are very sensitive to change in the temperate exposed to high level of microwave energy can ultra or kill sperm. According to one study, man who kept their cell phone in their pocket experience 35% reduction in sperm count. It take about one minute to boiled a cup of water in microwave oven consider this that the human brain is 90% of water.

Physiology

There is concern that radiofrequency (RF) energy produced by cell phones may distress the brain and nervous system tissue in the head because hand held cell phones are usually held close to the head. RF energy depend on several factors including: the amount of cell phone traffic at a given time, the size of the handset, how far the antenna is extended, the quality of the cell phone transmission, the distance from the nearest cell phone base station, the number and duration of calls, and whether or not a hands free device is used.

“Researchers have focused on whether RF energy can cause malignant (cancerous) brain tumors such as gliomas (cancers of the brain that begin in glial cells, which surround and support the nerve cells), as well as benign (noncancerous) tumors, such as acoustic neuromas (tumors that arise in the cells of the nerve that supplies the ear) and meningiomas (tumors that occur in then meninges, which are the membranes that cover and protect the brain and spinal cord). The salivary glands also may be exposed to RF energy from cellular telephones held close to the head.” (Cellular Telephone Use and Cancer Risk 1)

A brain tumor is a mass or growth of abnormal of tissue cells in your brain. There many different types of brain tumors exist. Some brain tumors are noncancerous such as benign, and some brain tumors are cancerous such as malignant. Brain tumors can begin in your brain and called primary brain tumors, or cancer can begin in other parts of your body and spread to your brain and called secondary brain tumors). The secondary brain tumor or cancer spread to the brain such as breast cancer, colon cancer, kidney cancer, lung cancer, melanoma, neuroblastoma, and sarcoma. The number of brain tumors increasing each year. There is evidence that the increase has been occurring for decades.

Precautionary

People are not going to stop using cell phones. Since many studies suggest that there may be risks of using cell phones. There are some ways to avoid cell phone dangers such as: limit the number of calls you make, limit the length of your calls, use hands free devices, put the cell on speaker phone, or hold the phone away from your ear, when speaking on your cell phone, alternate sides, limit your cell phone use in rural areas or anywhere signal is poor because more radiation is emitted when you are farther from a cell phone tower or base, text message instead of talking (never while driving!), do not wear wireless headset as if they were jewelry, and keep your phone out of your pocket. when using headset or speaker mode no reliable date exist on the upper limit of safe talk time, but corded phone headset can reduce any potential risk. These emit reduce RF energy. Earpieces do not emit as much as radiation as a cell phone, but they release some even after your call ends. Remove the device between conversations and only wear it when you really need it.

Symptoms

The signs of a brain tumor depend on the brain tumor’s size, location, and rate of growth mean how fast it grow. Generally signs cause by brain tumor such as: New onset or change in pattern of headaches, headaches that gradually become more common and more severe, unexplained nausea or vomiting, vision problems, such as blurred vision, double vision or loss of peripheral vision, gradual loss of sensation or movement in an arm or a leg, difficulty with balance, speech difficulties, confusion in everyday matters, personality or behavior changes, seizures, especially in someone who does not have a history of seizures, hearing problems, and hormonal (endocrine) disorders.

Radio frequency radiation may get in the way with the electrical fields of our cells. Common health challenges to radio frequency radiation include: abnormal cell growth and damage to cellular DNA, difficulty sleeping, depression, anxiety, and irritability, childhood and adult leukemia, eye cancer, immune system suppression, attention span deficit and memory loss, and infertility.

Doctors are not sure what cause the primary brain tumor, but they have acknowledged that may increase the risk of brain tumor. Risk of brain tumor depends on the following: your race, your age, exposure to radiation, chemical exposure on the job, and family history of brain tumor.

Treatment

Alternative brain tumor treatments have been proved to heal brain tumors. However, they may help with the side effects of your brain tumor and its treatment. Alternative treatments include: acupuncture, massage, meditation, relaxation exercises, and yoga.

Side effects may include nausea, vomiting, hair loss, and weakness. The immune system is usually covered up, which makes the person more at risk to infections. Other organ systems such as the kidneys or reproductive organs may be damaged. Surgery can cause both temporary and permanent changes. Side effects such as brain swelling, damage to normal tissue, mental-status changes, muscle weakness, or changes in any brain controlled function may occur and some may become permanent.

Treatment for brain cancer should be individualized for each patient. Treatment based on the patient's age and general health status as well as the size, location, type, and grade of the tumor. In most cases of brain cancer, radiation therapy, surgery, radiosurgery, targeted drug therapy, clinical trials, and chemotherapy are the main types of treatment. Often, more than one treatment type is used.

External radiation uses a high energy ray of radiation targeted at the tumor. The ray travels throughout the skin, the skull, healthy brain tissue, and other tissues to get at the tumor. The treatments are typically given five days a week for about four to six weeks. Internal radiation uses a small radioactive pill that is placed inside the tumor itself. The radiation emit from the pill destroys the tumor in the body. The radioactivity of the capsule decreases a bit each day. Chemotherapy is the use of controlling drugs to kill tumor cells. A single drugs or a mixture may be used. The drugs or pill are given by mouth. Two drugs, temozolomide also called temodar and bevacizumab also called avastin have recently been approved for the treatment of malignant gliomas.
