Definition of brain cancer

Brain cancer is abnormal cell growth ( tumor ) in the brain that is malignant. Cancer cells can control and take space, blood, and nutrients from healthy cells in the body.
Based on the cell type, brain tumors can be benign or malignant. Malignant tumors in the brain or brain cancer tend to grow faster and spread to other parts of the body, and can reappear even after being removed.

There are 4 stages of brain tumors that can be seen from the development of tumor cells and their expansion. In stage 1, if seen under a microscope, tumor cells still appear normal and growth is slow. Stage 2 is also indicated by slow growth of tumor cells, but tumor cells begin to appear abnormal and when raised tend to grow back. Whereas in stage 3, tumor cells no longer resemble normal cells and their development is active. While in stage 4, tumor cells are very different from normal cells and grow rapidly.
Brain cancer can originate from the brain cells themselves, or so-called primary brain cancer. Cancer cells can also come from other parts of the body that spread (metastasis) to the brain, and this condition is called secondary brain cancer.
Although classified as rare, brain cancer can occur at any age. According to WHO data in 2018, new cancer cases in Indonesia almost reach 350 thousand. From these cases, brain cancer ranks 17th with sufferers of more than 5000 people.
