Gene expression profiling

Unlike other diseases like cold, flu and some type of fever the cancer is not contagious. As specified earlier the cancer is caused by the growth of the foreign cells in your body which gets accumulated and forms as tumors which intern results in cancer a highly dangerous disease. Although doctors still never charted about the causes of cancer they have done many researches and found several phenomenon about the deadliest disease. One such result is that the cancer is not contagious. People need not fear that being with cancer affected person may harm them also but the case is not that cancer germs doesn’t gets diffused in air which subjects others also to enter into the pool of cancer. This is an important aspect to be quoted for awareness because people should not hesitate to behave with the cancerous people and they should treat them more politely. Although there are several treatments I the field medicine, nothing can replace the love and affection.

As proclaimed by the great experts the causes for the cancers are still mysterious. It is myth that is being spread among the people that people who have bad thoughts are being subjected to this type of harmful diseases and moreover they completely throw the blame on god. This talk is widely spread because not many people get affected due to the cancer and the probability is very less. After some deep analysis by the greatest researchers about the cancer they have identified some reason behind the killer. Yes as people know it is the unhealthy and unhygienic habits such as smoking and consuming alcohol are the two major reasons identified and people who are into this habit will have higher possibility rather that probability to be a victim of cancer. The researchers also proclaim that only these habits cannot be the reason for the cancer, even people who are completely health conscious may also be subjected to cancer and the causes for these are still in the blue.

Although there are several causes that induce the cancer cells to develop in the human body still the scientists have eventually proved that cancers can be prevented to certain extent. Of course the genetic reasons cannot be prevented as these are the certain occurrence due to the family oriented reasons. Statutory use of certain carcinogens on the human body helps to prevent certain types of cancer. As discussed in the earlier section about the vaccination, certain cancers that are causes due to the viruses can be prevented by using certain types of vaccines. It has been proved based on the practical experience that ovarian and endometrial cancers can be prevented using anti-oestrogens like tamoxifen and with aromatase inhibitors. Although it is explained the effective diet practices can reduce the risk associated with cancer but still there is no strong evidence between these two aspects. However increased in taking of fruits and vegetables and decreased in taking of fat will minimize the risk of cancer to certain extent.

This is also one among the latest technique that has been initiated to treat the cancer. This is a technique where small quantity of mRNA is acquired from the malignant cells. Once it is acquired it is being labeled with the fluorescent dye and hybridized on the surface on the robotically spotted arrays of thousands of cDNAs. This schematic approach helps the doctors to analyze the expressions of thousands of genes simultaneously. Based on the computer analysis of those data major sub groups of patients can be established on the basis of occurrence of over expression or under-expression genes. Obviously in several type of analysis on different cancer patients established using this procedure has distinctly different survival times. Although this method is cannot be significantly used to heal the cancer yet the method is more efficient in determining the prognosis rate of the cancer suffering patients. Of course using these data the doctors can alter the course of treatments over he patients.

This is also one of the advancements in the treatment of cancers after thorough research apart from the conventional treatments that included surgery, chemotherapy, immunotherapy and lot more. As the name represents it is the process of inducing genes into the normal or the malignant cells in order to attain the clinical benefit. It is being transfected using the viral or the non-viral vectors. Of course since the virus is being used it should be monitored that it is no way harmful to the patients. This kind of treatment is widely encouraged as it controls the cell proliferation and sometimes even cures the cancer. There are different types of gene therapy that had been introduced to treat the defects of the cancers. Another strategy introduced in the same platform is molecular chemotherapy in which the transgene is deleterious to the cancer cells either directly or indirectly over the cancer cells.
