In present times, statistics say that there are at least one hundred types of cancer, most of them being divided according to the organ or type of cell in which they start. Because abnormal cells divide without control and they invade other tissues, cancer penetrates into the body through the blood and lymph systems. Names like carcinoma, sarcoma, leukemia, lymphoma and myeloma and central nervous system cancers are just a few of the disastrous effects of cancer. When tissue is affected and when healthy cells are being attacked by cancer cells, the appearance of a tumor is inevitable. There are two types of tumors: the benign tumor, which is not cancerous ant the malignant tumor, which is cancerous.
Gold nanoparticles are characterized by a battery of methods, in order to create a certain specification for each product. These particles are used to kill solid tumor cancers, because they have the ability to target solid tumor cancers and have a great photo thermal conversion that enables the increase of temperature at the tumor. They are injected intravenously and they are present in the body for many days.
Other treatments which are used in the battle with cancer are the chemotherapy and the radiotherapy. These treatments assume the utilization of drugs and of a certain energy designed to remove cancer cells, in other words to remove tumors. The drugs used in chemotherapy do not just kill cancer cells, they also kill healthy cells. The death of these healthy cells is what generally causes the appearance of cancer.
Gold nanoparticles, also known as nanorods have been used in medicine from ancient times. In this procedure, cancer cells could be finally destroyed, first by detecting the toxins and the pathogens from the human body and than by eliminating the affected cells. For the patients who suffer from cancer, the most important thing is to treat and discover the disease from an early stage, in order to increase the chances of recovery.
Most of the people were not informed about this great discovery of using gold in the cure of cancer. So, it is very important to notice that gold is no more only a precious metal, but a fearsome enemy for the most serious diseases of mankind.
