Liver cancer is the sixth most common cancer in the world, and now researchers are developing new forms of treatment. If tests show you have liver cancer, there are several ways to treat the disease. One is removing the cancerous part of the liver. The other is having doctors replace the organ through a transplant operation. Patients who get someone else’s liver must take immuno-suppressant drugs the rest of their life. The drugs keep the body from rejecting the new organ. There may be serious side effects that come with taking those powerful medicines. Chemotherapy and radiation treatments are also used to treat liver and other cancers. Those treatments require the patient to take strong drugs or exposure to radiation. The drugs or radiation destroy the cancer cells. But then, the healthy cells around the tumor are damaged. Now scientists are working on an experimental, minimally invasive treatment. They say it reduces the chances of harming the patient. This treatment involves the use of natural, non-poisonous chemicals from plants. That is why the researchers call it a “green” method for fighting cancer.
