What is the difference between benign and malignant tumour?

The cells in a healthy individual normally grow, divide, age, die and are replaced. In some cases, cells may divide too rapidly or some old cells may fail to die. When this happens, an abnormal mass of solid tissues called a tumour is formed. Tumours vary in sizes and will cause swelling or lump as it grows bigger. Also a tumour can occur anywhere in the body. A tumour can be classified as benign or malignant. Benign tumour is non-cancerous, does spread to other body parts, can be completely removed, it’s not likely to recur and it’s not life threatening. Malignant tumour however is cancerous, can invade other body parts, if removed it can still return and it poses a life threatening condition. Unlike most malignant tumours, blood cancer does not usually take a solid form. An example of blood cancer is leukemia where abnormal white blood cells outnumber normal white blood cells.  Benign tumours can become cancerous. So watch out for any abnormal growth and consult with your doctor. Besides even though benign tumours are not life threatening some brain tumours can cause inflammation and pressure on sensitive tissues surrounding it.
