In this article, we will explain Chapter 8 "How to reproduce cells". A cell is a cell that is the smallest structural and functional unit in an organism (life). Robert Hooke found a cell in 1865. He discovered and named the nucleus by another scientist Robert Brown in 1833. In this article, we explain how cells work in the brain to various research and professors. The brain is a unique creature. This course provides background information that will help you understand major issues about articles.
Brain tumor is the proliferation of abnormal cells in brain tissue. Brain tumor is benign, there are no cancer cells or malignant tumors, and cancer cells rapidly proliferate. There is also a primary brain tumor derived from the brain. Others are metastatic, moving from the rest of the body to the brain. The doctor diagnoses the brain tumor through examination such as neurological examination, MRI, CT scan, biopsy and so on. Treatment options include observation wait, surgery, radiation therapy, chemotherapy, and targeted therapy. Targeted therapy uses substances that attack cancer cells without harming normal cells. Many people receive various treatments
Surgery, radiation therapy and chemotherapy are the major treatment categories of most brain tumors. Personal treatment plan usually includes a combination of these treatments. Surgical treatment attempts to remove all tumor cells by excising the tumor from normal brain tissue. This procedure, including opening the skull (craniotomy), is often referred to as an invasive procedure to distinguish it from noninvasive radiosurgery or radiotherapy as described below. Some brain tumors are called surgery by the surgeon, as it may lead to further brain damage and death if you try to remove cancer. However, brain tumors that are called surgical inoperable by the surgeon can be considered operable by other surgeons. Patients diagnosed with inoperable brain tumors should consider seeking a second opinion before surgical treatment is discontinued.
