A lot of patients suffering from colon cancer might well present no symptoms or signs during the earliest stages of the condition. When symptoms do eventually present, they can be many and varied, and can very much depend upon the size of the affliction, how far it has spread and also its actual location. It [...]
Prostate cancer has a number of symptoms, and it should be remembered that the most typical prostate cancer symptoms and those of a non-cancerous enlarged prostate are identical. As a result, medical advice should be sought as soon as possible on identification of any such symptoms. These symptoms include the sudden need to rush [...]
Cancer research is typically invested in by a number of different individuals, groups or organizations worldwide in the hopes of developing both treatment and cure for the disease. The state of California, for instance, has reportedly invested $10-12 million in direct cancer research annually, while the National Cancer Institute (NCI) within the United States has [...]
While cancer death statistics can vary from place to place it is generally estimated that roughly 7.2 to 7.5 million people worldwide die from cancer each year. In the United States alone where cancer death statistics are highly monitored each year has seen a steady death rate of 550,000 to 600,000 people year after year, [...]
There are a few major causes of skin cancer, but by far the most over-riding is excessive or constant over-exposure to ultraviolet (most often known as “UV”) radiation form the sun. Many people forget that the sun’s energy is actually a type of radiation and it consists of both visible and invisible rays. Invisible infrared [...]
Metastatic renal cancer is a type of kidney cancer, commonly known as metastatic renal cell carcinoma (RCC), and is a particularly dangerous form of the cancer. Originating in the small tubes that kidneys use to filter blood and remove toxins, RCC has a high resilience to most conventional radiation therapy and invasive surgery is generally [...]
Instances of cancer are on the rise, and have become more and more common and more highly publicized in recent times. Many people know or are aware of someone that either has or has had cancer, whether this is a friend, relative or someone at work. There are many cases, of course, of famous people [...]
For many women probably the first symptom of breast cancer is finding a lump in one of their breasts. This, however, is not necessarily a cause for immediate alarm as around 90% of breast lumps found are benign, which means that they are non-cancerous. It is important to know, however, that this can only be [...]
The symptoms of lung cancer can be many and various. Around one-fourth of those actually diagnosed with lung cancer present no symptoms at the time of diagnosis. Diagnosis and identification of the cancer normally occurs incidentally when the patient has a chest x-ray for an unrelated reason. The remaining three-fourths do develop certain commonly-known symptoms, [...]
It is now well known to medical science that the beginning point of all cancers is a change in either one cell or in a small group of cells. This means that, in the normal course of events, some years before a patient can even feel a lump and before a doctor or specialist is [...]
Nanotechnology deals with manipulating the structure as well as properties of matter at the atomic and molecular level. As the result of this maneuvering, the properties of matter change dramatically. While some insoluble elements develop high solubility capacity, inert substances start exhibiting catalyst properties. Owning to their size and properties, nanomaterials are extensively used for [...]
Nanotechnology is the science of maneuvering and modifying the structure and properties of matter at an atomic and molecular scale. Due to these manipulations, inert elements start to function as catalyst, and insoluble matter develop unique solubility capacity. Likewise, non-colloids begin exhibiting excellent colloidal properties and electrical non-conductors start conducting electricity. All these materials can [...]
Scientists from the University of Southampton’s School of Electronics and Computer Science have gotten an assignment to create a special technique to produce nanowires, which would make mass production possible. The final goal is to be able to perform quick blood tests without the need to go to a laboratory.
The British researchers are using the [...]
In today’s technological age, it seems advancements in all fields leap forward by the day. Medical technology certainly hasn’t been left out of the loop, and some of the breakthroughs in modern medicine have been quite revolutionary and had a huge impact. But where will the field of medicine be in 20 years from now? [...]
In 1974, Norio Taniguchi of the Tokyo Science University, defined the term nanotechnology for the first time. According to his definition, nanotechnology encompasses separating, processing, consolidating and deforming matter at atomic and molecular scales. Although the term nanotechnology got its definition in 1974, the actual concept was introduced way back in 1867, when James Clerk [...]
Researchers from Rice University, led by Professor Yildiz Bayazitoglu, have performed a research which showed that by combining two lasers and pointing them to nanoparticles in order to heat them up, it is possible to destroy the “bad” tissue, with minimum damage to healthy cells.
Of course, lasers and nanoparticles are already used in nanomedicine for [...]
Scientists from the Pennsylvania State University have found that a high amount of fluorescent molecules that naturally reside in human’s body can be used as biomarkers for cancer.
NADH (nicotinamide adenine dinucleotide) is an enzyme found in mitochondria. “Dysfunctional enzymes in the mitochondria are known to be associated with serious health problems such as cancer and [...]
You may have heard that nanotechnology is already being applied in many industry branches, but probably the most promising subfield of nanotechnology is nanomedicine. Researchers from the University of Alberta, led by Jie Chen, are working on developing a new technique which would allow them to replace chemotherapy and radiation, thus “killing” all the side [...]
Taiwan, among other Asian countries, is heavily investing in nanotechnology — especially nanomedicine. They recognized the potential, and they’re jumping into it. However, they’re being cautious — National Cheng Kung University in Taiwan started a project which is supposed to explore the effects of nanotechnology on health.
The main goal of this research is to minimize [...]
A team of scientists from the University of Toronto have found that, by modifying a protein that improves the process of preventing cancer growth, a new way of treating cancer is on the way. The protein they have been researching is called von Hippel-Lindau (VHL).
Tumors are known to have very low blood supply when they [...]
