New Cancer Research, Cancer And Nanoparticles Revealed
Have you heard of Nanoparticles? This article focuses upon something very exciting in the field of cancer research. I am talking about these nanoparticles – not Apple’s nano - but for treatments and a potential cure for cancer. Researchers are using the idea of the Trojan horse concept in these artificially produced cells. The idea is that nanoparticles can invade cancer areas without being recognised and release a toxic trail of drug into the cancer, killing it without harming good tissue. This really is the good news that we have been waiting for or is it? Well, you will have to read more in this article to get the facts on cancer treatment.

How Cancer Develops
The body never rejects a cancer because it is the body’s own cells that creates it. These cells are rogue cells – cells that have gone wayward. The body’s immune system allows these rogue cells to do what ever they want to because it recognises that these cells are ‘one of us’. The body’s immune system turns a ‘blind eye’ to the bad behaviour of these rogue cells. They multiply at a greater rate than normal cells to create tumours. Some tumours are not cancerous – they are benign. Please find included a short animation to explain what cancer is.
Dr Lesley Walker, of the charity Cancer Research UK, said: "These results are encouraging, and we look forward to seeing if this method can be used to treat cancer in people. "Gene therapy is an exciting area of research, but targeting genetic changes to cancer cells has been a major challenge. "This is the first time a solution has been proposed, so it's exciting news." Dated: 10th March 2009, bbc.co.uk.
Nanoparticles Development For Cancer Treatment
Cancer has it’s own circulatory system and becomes a self-satisfying body in itself. You might like to compare it to the growth of a baby within its own sack attached to the womb from the umbilical cord. This is a comparison - of course a baby is not a cancer but it seems to operate in the same way by feeding off of the mother or the host in the case of cancer.
Now cancer researchers are developing nanoparticles and tests are being carried out on animals. It seems that it won’t be too long before trials will take place. Thanks to the support of cancer charities like Cancer Research UK, who have prioritised research in genetics and this field, we could be well on the way to a cure.

There are many different therapies that nanoparticles are being developed for, but it is the difficult to access and incurable cancers that the focus is on. The researchers suggest that the technology could potentially help people with inoperable and difficult cancers. Cancers that are inoperable because they are close to vital organs and difficult cancers like pancreatic and liver cancer.
Nanoparticles Act Like Trojan
It has been highlighted that nanoparticles are a likely way to be able to transport genes into cancer cells. These artificially created cells are tiny but act like the Trojan horse. Once inside the cell, the genes contained within it recognises the cancerous environment and switches on, leaving a toxic trail of destruction in the cancer cell. This is very exciting and it is at this point you should look at the below video for further information.

Problems with Nanoparticles
Where there is a revelation, there are problems too. The science around nanoparticles is no exception. Before trials of these artificial cells can take place, researchers have to jump over the hurdle of demonstrating success from within animals. This is the direction science is heading into. This is widespread as testing is taking place with various different nanoparticle materials. Some are designed to seek out cancer cells, whilst others are arranged to combat conditions like diabetes. There are even multifunctional nanoparticles that are being tested to deliver cancer drugs and imaging molecules!
So what needs to be done before we can use nanoparticles in humans?
There are three challenges to combat before scientists can use nanoparticles in humans:
- Demonstrate that nanoparticles only targets cancer cells.
- Demonstrate the elimination of nanoparticles from the body.
- Ensure and demonstrate that nanoparticles will not trip the body’s immune response system.
Researchers and scientists also have to bare in mind other issues relating to the safe disposal of nanoparticles. As you know, these cells are tiny and could have adverse effects on health and the environment. There are fears, for example, that the particles might get into to the lungs and cause similar problems that asbestos can cause leading to mesothelioma. Click on mesothelioma to know more. Take a look at the video to learn more about these concerns.
Nanoparticles Will Eradicate Cancer Some Day Soon
Cancer has been a much-feared disease. The news of a diagnosis of cancer has been thought of as a death sentence in the past. Today, more and more people are surviving - thanks to the research and commitment of our scientists. Everyone has been touched with someone that they have known and loved with the disease. As medical advancements have improved, with the discovery and invention of nanoparticles, we have hope that cancer will be eradicated some day soon. This will be despite the contradictions – as stated in our last videos – and the hoops that research has to jump through in order to bring the material to trial.
