Cancer cells are regular cells that have undergone a certain transformation. The three aspects of the transformation are unlimited cancer cells growth, change and migration. As cancer cells are just regular cells affected by physical and/or chemical factors, what can we actually do to decrease the risk of cancer?
Most of the chemical mutagens and physical factors inducing gene mutation are known, most of them being carcinogenic: some of the chemical, commonly put into asphalt, can cause skin cancer; serious benzene poisoning can induce leukemia; lung cancer is partly caused by excessive smoking – the benzopyrene, tobacco tar and other substances in cigarettes have a direct effect on health; leukemia and bone marrow incidence is high among people in frequent contact with radioactive materials or radiation. Although it is not easy to change the environment around, you might want to take up cycling to contribute to environmental protection or improve safety standards at work to prevent harmful environmental effects. For the patients with cancer, though, the first step is attacking the cancer cells and stopping their growth and development.
Presently, platinum-containing drugs such as cisplatin, carboplatin and oxaliplatin are commonly used for cancer treatment. These drugs work by disrupting the normal double helix structure of the DNA strands of cancer cells, resulting in partial denaturation of these cells as they simultaneously lose their abilities to replicate. Such method, if successful, prevents cancer cell division. The problem is that while disrupting the functionality of the cancer cells, these drugs also have strong side-effects: cisplatin could cause renal toxicity, nausea and vomiting; carboplatin, despite of having stronger effects in tumor cell functionality than cisplatin, could cause marrow suppression, gastrointestinal reactions, toxicity nephrotoxicity, ototoxicity,bleeding, etc.
Traditional anti-cancer medicine helps fight cancer but at the same time is extremely harmful to the body. In order to avoid such side effects, it is best to specifically focus on the disruption of cancer cells. Targeted molecular treatment is currently the most efficient method of cancer treatment with bright development prospects. By targeting specific protein molecules or cancer cell gene fragments, the targeted treatment therapy works at both the cellular and the molecular levels.
The specific tumor cell tissue located a specifically chosen to achieve the most efficient results. Multiplex PCR technology can presently research and determine the target areas of cancer cells and guide the usage of Cetuximab, Trastuzumab and other molecularly-targeted cancer treatment drugs, thus reducing the negative effect on the surrounding healthy cells. The usage of such treatment can significantly reduce the suffering of cancer patients without reducing the effectiveness of the treatment.
