SYMPTOMS OF BRAIN CANCER.............
Brain cancer symptoms vary from patient to patient, and most of these symptoms can also be found in people who do NOT have brain cancers. Therefore, the only sure way to tell if you have a brain cancer or not is to see your doctor and get a brain scan.
brain cancer symptoms We did a survey of over 400 brain cancer patients to learn what symptoms they had that caused them to seek medical care.

brain cancer symptoms They reported:

brain cancer symptoms Headaches: This was the most common symptom, with 46% of the patients reporting having headaches. They described the headaches in many different ways, with no one pattern being a sure sign of brain cancer. Many - perhaps most - people get headaches at some point in their life, so this is not a definite sign of brain cancers. You should mention it to your doctors if the headaches are: different from those you ever had before, are accompanied by nausea / vomiting, are made worse by bending over or straining when going to the bathroom.(1)

brain cancer symptoms Seizures: This was the second most common symptom reported, with 33% of the patients reporting a seizure before the diagnosis was made. Seizures can also be caused by other things, like epilepsy, high fevers, stroke, trauma, and other disorders. (3) This is a symptom that should never be ignored, whatever the cause. In a person who never had a seizure before, it usually indicates something serious and you must get a brain scan.

brain cancer symptoms A seizure is a sudden, involuntary change in behavior, muscle control, consciousness, and/or sensation. Symptoms of a seizure can range from sudden, violent shaking and total loss of consciousness to muscle twitching or slight shaking of a limb. Staring into space, altered vision, and difficulty in speaking are some of the other behaviors that a person may exhibit while having a seizure. Approximately 10% of the U.S. population will experience a single seizure in their lifetime.

brain cancer symptoms Nausea and Vomiting: As with headaches, these are non-specific symptoms - which means that most people who have nausea and vomiting do NOT have a brain cancer. Twenty-two percent of the people in our survey reported that they had nausea and /or vomiting as a symptom.

brain cancer symptoms Nausea and / or vomiting is more likely to point towards a brain cancer if it is accompanied by the other symptoms mentioned here.

brain cancer symptoms Vision or hearing problems: Twenty-five percent reported vision problems. This one is easy - if you notice any problem with your hearing or vision, it must be checked out. I commonly hear that the eye doctor is the first one to make the diagnosis - because when they look in your eyes, they can sometimes see signs of increased intracranial pressure. This must be investigated.

brain cancer symptoms Problems with weakness of the arms, legs or face muscles, and strange sensations in your head or hands. Twenty-five percent reported weakness of the arms and/or legs. Sixteen percent reported strange feelings in the head, and 9% reported strange feelings in the hands. This may result in an altered gait, dropping objects, falling, or an asymmetric facial expression. These could also be symptoms of a stroke. Sudden onset of these symptoms is an emergency - you should go to the emergency room. If you notice a gradual change over time, you must report it to your doctor.

brain cancer symptoms Behavioral and cognitive problems: Many reported behavioral and cognitive changes, such as: problems with recent memory, inability to concentrate or finding the right words, acting out - no patience or tolerance, and loss of inhibitions - saying or doing things that are not appropriate for the situation.

brain cancer symptoms IF you think something is wrong, go see your doctor. Explain that you are worried it is a brain cancer. Keep in mind that brain cancers are relatively rare compared to most other disorders, so the primary care doctor is not usually going to be thinking it is a brain cancer. They first think of more common causes of the symptoms. Sixty-four percent of the time, the doctor thought it was NOT a brain cancer when respondents first went to the doctor. More than half of the people reported that they had the symptoms for more than a month before the correct diagnosis of brain cancer was made. With the malignant brain cancers, a delay of a month in starting treatment can make a major impact on the outcome.

Cancer, also called malignancy, is an abnormal growth of cells. There are more than 100 types of cancer, including breast cancer, skin cancer, lung cancer, colon cancer, prostate cancer, and lymphoma. Symptoms vary depending on the type. Cancer treatment may include chemotherapy, radiation, and/or surgery.

What are the symptoms of cancer?
Cancer symptoms are quite varied and depend on where the cancer is located, where it has spread, and how big the tumor is. Some cancers can be felt or seen through the skin - a lump on the breast or testicle can be an indicator of cancer in those locations. Skin cancer (melanoma) is often noted by a change in a wart or mole on the skin. Some oral cancers present white patches inside the mouth or white spots on the tongue.

Other cancers have symptoms that are less physically apparent. Some brain tumors tend to present symptoms early in the disease as they affect important cognitive functions. Pancreas cancers are usually too small to cause symptoms until they cause pain by pushing against nearby nerves or interfere with liver function to cause a yellowing of the skin and eyes called jaundice. Symptoms also can be created as a tumor grows and pushes against organs and blood vessels. For example, colon cancers lead to symptoms such as constipation, diarrhea, and changes in stool size. Bladder or prostate cancers cause changes in bladder function such as more frequent or infrequent urination.

As cancer cells use the body's energy and interfere with normal hormone function, it is possible to present symptoms such as fever, fatigue, excessive sweating, anemia, and unexplained weight loss. However, these symptoms are common in several other maladies as well. For example, coughing and hoarseness can point to lung or throat cancer as well as several other conditions.

When cancer spreads, or metastasizes, additional symptoms can present themselves in the newly affected area. Swollen or enlarged lymph nodes are common and likely to be present early. If cancer spreads to the brain, patients may experience vertigo, headaches, or seizures. Spreading to the lungs may cause coughing and shortness of breath. In addition, the liver may become enlarged and cause jaundice and bones can become painful, brittle, and break easily. Symptoms of metastasis ultimately depend on the location to which the cancer has spread.

How is cancer classified?
There are five broad groups that are used to classify cancer.

Carcinomas are characterized by cells that cover internal and external parts of the body such as lung, breast, and colon cancer.
Sarcomas are characterized by cells that are located in bone, cartilage, fat, connective tissue, muscle, and other supportive tissues.
Lymphomas are cancers that begin in the lymph nodes and immune system tissues.
Leukemias are cancers that begin in the bone marrow and often accumulate in the bloodstream.
Adenomas are cancers that arise in the thyroid, the pituitary gland, the adrenal gland, and other glandular tissues.
Cancers are often referred to by terms that contain a prefix related to the cell type in which the cancer originated and a suffix such as -sarcoma, -carcinoma, or just -oma. Common prefixes include:

Adeno- = gland
Chondro- = cartilage
Erythro- = red blood cell
Hemangio- = blood vessels

Lipo- = fat
Lympho- = white blood cell
Melano- = pigment cell
Myelo- = bone marrow
Myo- = muscle
Osteo- = bone
Uro- = bladder
Retino- = eye
Neuro- = brain
