Cancer, we hear about it every day. More and more people being diagnosed as the years pass on. Out of all the types of cancer there is one that keeps us mind blown the most and that’s brain cancer. With 78’000 people diagnosed a year, 28’000 being adults, 13’350 men and 10’420 women with 4’000 being kids. Brain cancer is a real mystery from the history of it, how it starts in the brain, and the causes of it to the new treatments that are coming into play. Throughout recorded history humans and other animals have had cancer. The earliest evidence of cancer has been found in fossilized bone tumors, human mummies, also ancient manuscripts. Osteosarcomas have also been found in mummies which is a type of bone cancer. The oldest description of

If the cancer travels to the brain it is called secondary cancer, or also known as metastases. This happens when some cells break away from the primary spot and can move through the bloodstream or lymph system to other parts of the body where it forms a new tumor. This secondary cancer is made from the same cells as the primary. It is important to know where your primary cancer was because this will tell your doctor what kind of treatment is needed. It is possible for any cancer to spread to the brain. Grades of brain cancer can indicate how aggressive the cancer is, the type of brain cancer shows what kind of brain cells started the tumor. The grade depends on how the tumor looks under a microscope. The grade also shows insight to the cells growth rate. In grade 1 the tissue is benign, here the cells look almost normal but grow slowly. In grade 2 the tissue is malignant; the cells start to look less like normal cells. In grade 3 the malignant cells look a lot different; these cells are actively growing and show a distinct abnormal appearance. In grade 4 the malignant tissue cells grow very quickly, and look nothing like normal cells. The spread of cancer cells from body organ to brain is known as metastatic brain cancer. Both primary and metastatic brain cancer are not fully
