Malignant
There are certain diseases, such as cancer, that are either harmless or pose a threat to the person's health and longevity of life. Malignant diseases are known to be very harmful and at times, life threatening. Malignant areas of the body, such as tissue or tumors can invade normal functions of other parts of the body. Malignant tumors can also go through the process of metastasis, or the spreading of the unhealthy cells.
What most people are afraid of is that if they are diagnosed with a malignant form of cancer or other disease, that they will experience rapid deterioration of life and a quick death. This is not entirely true for most cases. If caught at a reasonable time, there is much hope to believe that the tumor can go through a malignant transformation, where the cell changes from malignant to benign (or non cancerous). There are certain times, however, where the malignant area that is infected has spread its dangerous cells to other parts of the body causing those areas who may have been benign to become malignant as well. These occurs mostly in cancers that are found to be in later stages and are having negative reactions to types of treatments. Malignant areas of the body are often hard to treat because of the resistance to medications and treatments. The later the stage the higher the severity of the cancer can often cause malignant areas to be untreatable. The most important thing for doctors to determine is the location of the tumor and how to treat it effectively. Sometimes the best option for this is for a biopsy to take place. A biopsy is responsible for removing a portion of the infected area to determine whether or not there are cancerous cells present. The patient and doctor can determine the best way (if any) to remove the cancerous cells from the body. It is important to remember that maintaining a healthy lifestyle, diet, exercise and attitude is the best way to prevent malignant tumors from invading the body.
