Fortunately, with the advancement of medical science and early diagnosis of many types of cancer, we can hope for its complete treatment. Some believe that cancer is a disease that occurs mostly in elderly people. Although most of the time they are right, but many young people also get cancer. A large number of researchers around the world are working to find the best and newest way to treat cancer. Among these researchers, some of them are trying to reduce the medical and therapeutic wastes that cause the patients a lot of pain. One of the important side effects of radiotherapy is the destruction of healthy cells and damage to the skin, which causes secretions, wounds and skin necrosis. Currently, to prevent these wastes, dozang oxide cream or ointment is used, which has not been seen to have a good effect. Fortunately, there is a lot of information in modern and ancient medicine related to the healing properties of aloe plant, including the healing of skin wounds, burns, sunburn, and skin inflammation, which facilitates its use in modern medicine. Radiotherapy in high doses destroys cancer cells or slows their growth by damaging DNA. Cancer cells whose DNA has been damaged beyond repair will stop dividing and die. When damaged cells die, they are broken down and removed by the body. Radiotherapy does not kill cancer cells immediately. It takes days or weeks for the treatment to damage the DNA enough to kill the cancer cells. Then, cancer cells continue to die for weeks or months after the end of radiation therapy.
