Future of Cancer Treatment: A guide to new medicines and surgical techniques
Cancer is not a new disease and has distressed people throughout the world since a very long time. Some of the earliest evidence of human bone cancer dates back to 1600 B.C. when it was found in mummies in primordial Egypt and in ancient manuscript.
At present, it is the second leading cause of death on the planet after the cardiovascular diseases. However, millions of cancer affected people have been able to extend their life owing to early detection and adequate treatment. And the credit for it goes to the advancement in technology and medical science.
Once, the disease was considered incurable but today, many experimental cancer treatments are also under development as scientists are continuously researching on the subject.In this article, we will discuss about the new medicines and surgical techniques to cure cancer:
Cancer Treatment and Goals
Cancer can be treated by different methods such as chemotherapy, surgery, hormonal therapy, radiation therapy and targeted therapy. The choice of treatment depends upon certain factors like the location and status of the tumor, stage of the disease as well as the general condition of the patient.
The ideal goal of the treatment is – complete removal of the cancer without causing any harm to the rest of the body, i.e. achieving cure with near zero adverse effects. Owing to the complexity of the disease, it is essential that the scientific battle be fought against cancer in all frontiers.
Future of cancer Treatment
In recent years, the improvement in knowledge about cancer biology has led to remarkable progress in cancer detection, treatment and prevention. Today, cancer research is advancing on many fronts and some of them are mentioned below.
More Targeted Treatments
Today, doctors have a better understanding of the underlying molecular biology of cancer cells. As a result, new classes of molecules antisense oligodeoxynucleotides and small interfering RNAhave been developed for treating cancer.
This includes the usage of extremely tiny particles for diagnostic imaging to more precise locations of the tumor in order to deliver drugs more effectively and specifically into the cells.
RNA expression profiling allows scientists to ascertain relative amounts of several RNA molecules at one time. This information about the type of proteins or RNA molecules present in cancer cells can tell how a cell is behaving and usually aids in predicting the drugs that is likely to cause a particular tumor to respond.
In many clinical trials done recently, angioinhibitors were also being used in permutation with conventional chemotherapy. It is a type of targeted treatment that uses drugs to stop tumors from making new blood vessels. In trials, doctors combine a very low dose of chemotherapy followed by angioinhibitor therapy.
Preventive angioinhibitory therapy might also be possible in future because it is usually less toxic and less vulnerable to orientation of acquired drug resistance. Lately, some reports suggested that few food items also contain angioinhibitory, thus it becomes significant to identify them and use as prevention for cancer.
The present medical research is entirely focused upon developing techniques to win the war against human cancer. The medical science still hasn’t developed ‘cure all’ drug for cancer, however, many new cancer treatments and drug targets have been discovered. More research studies and clinical trials tend to play a vital role in finding an adequate cure for the deadly disease cancer.
