What are brain metastases?
brain metastases are cancer that originally developed in other parts of the body, but spread to the brain. They are usually called secondary cancer when they come outside the brain, in areas such as lungs, kidneys or colon. The original source of cancer, which caused spread to other places, is often called primary cancer.
primary cancer that have a high incidence of brain spread include breast cancer and lung cancer. Other cancer that can cause less frequent brain metastases are those that result from the large intestine, testicles, ovaries and kidneys. Melanoma, which is cancer caused by cells producing melanin, such as skin, was also involved to cause cancer brain metastases in some cases.
The occurrence of primary brain cancer is technically less common than the occurrence of brain cancer metastases. Generally, brain metastases occur more often in adults and elderly and rarely occur in children. In the male population, the Lrakova Ung is usually the causeIn brain metastases, while women's breast cancer is often the main cause.
Cancer have many ways to spread inside the body. They usually attack neighboring tissues and organs, leading to the growth of secondary cancers in these areas. When cancer cells reach a bloodstream or lymph nodes, they are often able to spread to neighboring areas and distant places inside the body. For example, cancer cells from the lungs usually spread to the brain through arteries, because the blood that passes through the lungs for oxygenation goes directly to the brain to provide oxygen into the brain tissues.
brain metastases can grow in any part of the brain. They often cause direct brain tissue damage, resulting in swelling, which can often lead to the compression of vital parts of the brain as cancer grow. Symptoms of brain metastase include head, movement and speaking problems, double vision and seizures.
patients with diagnCancer usually undergo treatment to stop the growth of primary cancer and prevent the spread of cancer to other parts of the body. When brain metastases appear, treatment technically failed to stop cancer. The prognosis for someone with brain metastases is usually poor and the result is often death. Treatment and treatment of patients with brain metastases often requires the efforts of many medical experts, including neurosurgeons, neurologists and oncologists.
