Ongoing Cancer research is need to help prevent this terrible disease.
Early Cancer Research reveled a grouping of over 100 different diseases that are identified as an uncontrolled cellular expansion, local cell tissues intrusion, and distant metastasis. Most medical professionals find it problematic to settle on an exact definition of cancer because there are many varieties.
The highly regarded British oncologist R.A. Willis identifies cancer as an irregular mass of tissue, of which, that tissue proliferates and exceeds the surrounding tissue. It is likely uncoordinated with the growth of the healthy surrounding tissue and it becomes persistent in an extreme manner even after cessation of the stimuli that evoked the cellular transformation.
The elements through which cancer takes place are somewhat understood. Cancer is assumed to progress from cells that have been altered and changed from the typical features that manage normal proliferation and growth of cells. New evidence bolsters the concept that carcinogenesis is a genetically controlled multistage progression.
Stage one of such a process is the commencement phase that starts with the subjection of cellular material to carcinogenic chemicals or materials which result in various types of genetic damage. This genetic damage occurs in certain mutations of the normal cells. The mutated cellular material starts to grow until it forms its own colony.
The next stage is a promotion. This is where cancer-causing agents (or various other suspected cancer-causing elements) modifies the tissue surroundings in a manner that assists the growth of the mutated cell population over that of the normal cells. The most significant difference amidst both of these stages is the later stage which may be reversible; therefore, it will likely be the target of any potential future chemoprevention strategies.
The following phase is the conversion process of mutated tissues to cancerous tissues. Anywhere from 5-20 years could lapse for the changeover of non-cancerous cells to fully develop into malignant cancer that can be detected clinically.
The final stage referred to as the progression phase is when further genetic modifications take place inducing a rise in the growth and metastasis of the altered cell tissue.
Cancer is now a major healthcare condition in many areas around the globe. Tens of millions of new cases are uncovered yearly, with more than six million fatalities estimated through the year 2000. The approximated quantities of incidence and death in 2002 were markedly increased as 10.9 million new cases were diagnosed, with 6.7 million new deaths caused by cancer.
These days even advanced nations are struggling with solving the cancer epidemic. In the USA alone, over 2 million new cases of cancer will be diagnosed with over 562,340 deaths occurring because of cancer. This figure corresponds to roughly 25 % of all the deaths, which makes cancer the second leading reason for death after heart disease.
Some Relevant Cancer Knowledge
The most prevalent cancer in males is cancer of the prostate, which represents nearly 25% of newly recognized cancer in men. This is accompanied by malignancies of the lung, bronchus, and then colon and rectum.
The commonest cancer in females is cancers of the breast that form up to 27% of the total amount of new cancer in women. This is followed by various forms of lung and bronchial cancer, then and colorectal cancer.
Other Cancer Research Data
The WHO says the 7.4 million deaths that happen on the planet are primarily due cancer, Lung cancer will kill more than 1.3 million people worldwide.
The rate of survival elevates as new drug treatment options and management approaches are developed. For example, in the 1930s barely 20% of cancer sufferers lived 5 years after treatment. That changed in the 1940s when the survival rates increased to 25 %.
Through the 1960s, the 5-years survival rose to 33 %, and then again in the 1970s, it rose to 38%. Nowadays days, 51 % of cancer sufferers live for five or, even more, years.
That being said, at the same time as the rate of survival improves the number of cases and rates of mortality has been rising. Today over 22% of deaths related to cancer are projected to increase, which includes an estimated 12 million deaths by 2030.
This contradiction between the rise in the 5-years survival and the rise of the mortality rate is attributed to our increased life span. Another reason for the rate of increase in mortality is due to the remarkable increases in carcinoma of the lung.
Ongoing cancer research at the nano scale level is helping doctors better understand how the environment plays a role in genetic mutations involved in cancer. This rapidly advancing field of study is known as Nanobiophysics.
Nano researchers believe that environmental genetic information is embedded at the molecular level and this can lead to cancer. That theory best explains the anomaly of identical twins where one gets cancer but the other does not.
Nano researchers have developed a new device called Gene Radar, which can detect any disease having a unique genetic fingerprint or structure such as Ebola, or even cancers.
