There are many approaches to cancer treatment; some are controversial, while others give more of a homeopathic perspective. Current studies on cancer involve nanoparticle-based technologies that could beat cancer by drug delivery via nanoparticles.
For years researchers have begun biomedical studies that have shaped the landscape of medical intervention. The use of nanoparticles have proved to be promising as continued tests show positive results from the medication that is attached to the nanocarrier system, which is used to target tissues in need of treatment. Such a treatment is designed to “overcome natural barriers such as the blood-brain barrier (BBB).” This is perfect for treating neurological diseases deemed incurable as the nature of the targeted tissue is highly sensitive.
Such approaches are promising as teams of researchers have developed treatments that have the ability to beat cancer cells with mini-warriors of the nanoparticle kind, based on the formulations of drugs carried. This is good news for cancer patients who have metastasis, as this is the stage of cancer that has a limited option for treatment.
The human body can easily excrete white blood cells which make it harder to battle cancer cells if the white blood cells are not in the body long enough. In a recent study nanoparticles were designed with fat molecules no bigger than dust particles and have been tested as an attachment to the white blood cells which gives white blood cells a chance to stay in the blood system to fight moving cancer cells. Basically, such an approach can dramatically reduce the spread of cancers in bone marrow and lymph nodes, thus allowing easier control and eradication of a primary tumor in a timely manner.
The design of nanoparticles is that which mirrors macromolecular structures within living cells. This makes it easy for nanoparticles to facilitate distribution of medication. Nanoparticles also have a high propensity of saturation which allows for quicker therapeutic action.
Biomedicine has come a long way with unique systems that utilize molecular sciences that are highly explicit in medical intervention. The medical approach to all stages of cancer continues with support; however, much research is only as good as the breakthroughs that follow. An expert from London’s Institute of Cancer Research mentions that it would be better to try this approach on distant organs already ridden with cancer cells. Still, the fact that nanoparticles can be strapped with explosives that can destroy the enemy on target should speak for itself.
What makes the nanoparticle-based drugs such an appealing treatment is the fact that it treats the stages of cancer that are dire – the stage that leaves little to no options available. The development of a strategy to target and annihilate metastic cancer cells is an approach that may pave the way for other treatments for what is deemed as incurable as in neurological diseases.
The fact that such research continues to move forward is truly telling of how much it has accomplished in its infancy. Nanoparticle-based drugs are certainly a breakthrough that can beat cancer in all stages.
