The brain and spinal column make up the central nervous system (CNS), where all vital functions of the body are controlled. When tumors arise in the central nervous system, they are especially problematic because a persons thought processes and movements can be affected. These tumors can also be difficult to treat because the tissues surrounding a tumor that may be affected by surgery or radiation may play a vital role in functioning.

There are two main types of brain cancer. Primary brain cancer starts in the brain. Metastatic brain cancer starts somewhere else in the body and moves to the brain. Brain tumors can be benign, with no cancer cells, or malignant, with cancer cells that grow quickly.

Alternative treatments have not been shown to cure brain tumors and should never be substituted for conventional therapy. However, complementary therapies (used with, not instead of, standard treatments) can help some patients cope with the stress of their illness and side effects of their treatment.

Meningiomas grow from the meninges. They are usually benign. Because these tumors grow very slowly, the brain may be able to adjust to their presence; meningiomas often grow quite large before they cause symptoms. They occur most often in women between 30 and 50 years of age.

Treatment:

Surgery is the preferred treatment for accessible meningiomas and is more successful for these tumors than most tumor types. For those with minor symptoms or an inaccessible tumor, close observation may be the first course of action. If the entire tumor is not removed surgically, or if it recurs, additional treatment such as radiation may be used. Stereotactic radiation is often preferred to reduce damage to healthy tissue. The effectiveness of chemotherapy and hormone therapy is being investigated in clinical trials.

Malignant brain cancer is one of the most lethal types of cancer in adults and is the second leading cause of cancer death in children. Many current ways of treating the disease fail to provide long-term management because they ineffectively target tumor cells and harm the health and vitality of normal brain cells.

Treatment:

Chemotherapy

Chemotherapy consists of a series of drugs that interfere with the normal functioning of the rapidly dividing cells of the tumor. This prevents the tumor from growing. Most of these chemotherapy drugs are given in combination so that they are most effective. Research is being conducted to determine the best combination of chemotherapy drugs to combat brain tumors. Some chemotherapy drugs are injected directly into the bloodstream while others can be taken by pill, at home.

The KetoCal diet gets around this dilemma by essentially starving the brain tumor cells of the sugary molecules on which they rely for growth and survival. Because of its special composition, the diet deprives the tumor cells of the glucose they need; at the same time, the diet provides normal brain cells with ketones, a class of organic compounds they can metabolize effectively but the tumor cells cannot.

Complementary and Alternative Medicines:

Complementary medicine is thought of as treatments used in addition to the conventional therapies your doctor may prescribe, such as using tai chi or massage in addition to prescription medicine for anxiety.
Alternative medicine is generally thought of as being used instead of conventional methods. For example, this might mean seeing a homeopath or naturopath instead of your regular doctor.

Brain Cancer – Symptoms of Brain Cancer

Brain cancer is a disease of the brain where cancer cells (malignant) grow in the brain tissue. Cancer cells grow to form a mass of cancer tissue (tumor) that interferes with brain tissue functions such as muscle control, sensation, memory, and other normal body functions. Tumors composed of cancer cells are called malignant tumors, and those composed of noncancerous cells are called benign tumors. Cancer cells that develop from brain tissue are called primary brain tumors. Statistics suggest that brain cancer is not rare and is likely to develop in about 20,000 people per year.

There are two main types of brain cancer. Primary brain cancer starts in the brain. Metastatic brain cancer starts somewhere else in the body and moves to the brain. Brain tumors can be benign, with no cancer cells, or malignant, with cancer cells that grow quickly.

Primary brain cancer rarely spreads beyond the central nervous system, and death results from uncontrolled tumor growth within the limited space of the skull. Metastatic brain cancer indicates advanced disease and has a poor prognosis.
Metastatic brain tumors are made of cancerous cells from a tumor elsewhere in the body. The cells spread to the brain from another tumor in a process called metastasis. About 25% of tumors elsewhere in the body metastasize to the brain.

Symptoms of Brain Cancer

Brain tumors can damage vital neurological pathways and invade and compress brain tissue. Symptoms usually develop over time and their characteristics depend on the location and size of the tumor.
Cancers are typically painless at first. As they grow, the first symptom is often a mild discomfort, which may steadily worsen into increasingly severe pain as the cancer enlarges. The pain may result from the cancer compressing or eroding into nerves or other structures.

The symptoms are caused by the tumor pressing on or encroaching on other parts of your brain and keeping them from functioning normally.
A sign is also an indication that something is not right in the body. But signs are defined as things that can be seen by a doctor, nurse, or other health care professional. Fever, rapid breathing rate, and abnormal breathing sounds heard through a stethoscope may be signs of pneumonia.

As the skull is made of bone, there is a fixed amount of space for the brain to take up. The growing tumour increases the pressure inside this fixed space. This is called 'raised intracranial pressure'.

Motion sickness is a very common disturbance of the inner ear that is caused by repeated motion such as from the swell of the sea, the movement of a car, the motion of a plane in turbulent air, etc. In the inner ear (which is also called the labyrinth), motion sickness affects the sense of balance and equilibrium and, hence, the sense of spatial orientation.

Brain tumors can often present different symptoms depending on the location of the tumor. There are general brain tumor symptoms that need to be checked out by a doctor if they are experienced.

Fits are one of the commonest symptoms of brain tumours. About 1 in 4 people with a brain tumour first go to their doctor because they have had a fit. A fit can just be jerking or twitching of a hand, arm or leg.

At the late stages of the disorder, dramatic changes in blood pressure may occur. Seizures are a common symptom of benign brain tumors and slow-growing cancers. Tumors can cause a part of the body to weaken or feel paralyzed. Hearing, sight and the sense of smell can be affected.
