are brain lesions the same as tumors?

Tumors: Tumors are types of brain lesions and may be benign (meningiomas are the most common) or malignant like glioblastoma multiforme. Tumors in the brain may also be metastatic, spreading from cancers that arise primarily from another organ. Symptoms occur depending upon the location and size of the tumor.

Pituitary tumors are often considered brain tumors, and they make up 12 to 19 percent of all primary brain tumors. But most pituitary tumors are benign and most of them are treatable.

A tumor is a commonly used, but non-specific, term for a neoplasm. The word tumor simply refers to a mass. This is a general term that can refer to benign (generally harmless) or malignant (cancerous) growths.

1) Brain cancers are rare. In the US, the incidence (that is, the number of newly diagnosed cases per year per 100,00 population) of all brain cancers is 6 cases per 100,000. (By contrast, the incidence of breast cancer is 125 per 100,000, and that of prostate cancer is 120 per 100,000).

Although any lump formed by body cells may be referred to technically as a tumor. Not all tumors are malignant (cancerous). Most breast lumps – 80% of those biopsied – are benign (non-cancerous).

A cancer, or tumor, can occur in any organ or tissue of the human body. Solid tumors form lumps, while liquid tumors flow freely in the blood.

These lesions make it difficult for messages to be sent and received properly between the brain and the rest of the body. Tumors: Tumors are clumps of cells that grow abnormally from normal tissue. Some tumors in the brain are noncancerous, or benign. Others are cancerous.

Most bone tumors are non-cancerous (benign). Some are cancerous (malignant). Occasionally infection, stress fractures and other non-tumor conditions can closely resemble tumors. Benign tumors are usually not life threatening.

The signs symptoms of brain tumors depend on their size, type, and location. The most common signs symptoms include headaches; numbness or tingling in the arms or legs; seizures; memory problems; mood and personality changes; balance and walking problems; nausea and vomiting; or changes in speech, vision, or hearing.

Glioma is a type of brain cancer that is often – but not always – malignant. In some cases, the tumor cells do not actively reproduce and invade nearby tissues, which makes them noncancerous. However, in most cases, gliomas are cancerous and likely to spread.

Primary brain tumors start in brain tissue and tend to stay there. Secondary brain tumors are more common. These cancers start somewhere else in the body and travel to the brain. Lung, breast, kidney, colon, and skin cancers are among the most common cancers that can spread to the brain.

Brain lesions are a type of damage to any part of brain. Lesions can be due to disease, trauma or a birth defect. Sometimes lesions appear in a specific area of the brain. At other times, the lesions are present in a large part of the brain tissue.

A tumor is an abnormal growth of cells that serves no purpose. A benign tumor is not a malignant tumor, which is cancer. It does not invade nearby tissue or spread to other parts of the body the way cancer can.
792031
A tumor can be benign (not dangerous to health) or malignant (has the potential to be dangerous). Benign tumors are not considered cancerous: their cells are close to normal in appearance, they grow slowly, and they do not invade nearby tissues or spread to other parts of the body. Malignant tumors are cancerous.

Meningiomas can be low to high grade (grades 1–3). Meningiomas are a common primary brain tumour in adults. Sometimes meningioma runs in families, especially in people with neurofibromatosis. Meningioma occurs more often in women.

Tumors in the brain can disrupt brain function, affecting your personality and behavior. They can also cause unexplained mood swings.

Some brain tumours grow very slowly (low grade) and cannot be cured. Depending on your age at diagnosis, the tumour may eventually cause your death. Or you may live a full life and die from something else. It will depend on your tumour type, where it is in the brain, and how it responds to treatment.
