A treatment with no side effects and is compatible with a normal life for as long as it lasts. Well, that day may be closer thanks to therapy, “Kanzius RF”.
Its effectiveness has been 100% when cancer cells stop and not hurt those healthy cells that were in the environment.
What we have now apparently has the potential to treat a wide variety of cancers. ”
Current treatments with radiation and chemotherapy are effective but often cause side effects in many patients and that, besides cancer cells, healthy cells also die.
Therapy “noninvasive”
Kanzius RF therapy is noninvasive, and uses radio waves combined with gold or carbon nanoparticles, whose therapeutic use has a long history behind it. Scientists have proven these particles in the bloodstream as a vehicle to carry drugs or as guests in research.
Nevertheless, there are numerous unresolved issues regarding the safety and security offered by these nanoparticles. However, in recent years they have become the focus of numerous investigations, including those related to cancer.
The “addiction” to certain growth factors contributes to the development of cancers caused by epigenetic changes, such as inappropriate activation of normally silent gene.
It is believed that blocking this addiction might help prevent cancer development.
Cells were compared mice with a single copy gene activated IGF-II growth factor (insulin-two) with cells from mice with both copies of IGF-II activated. Normally, only one copy of the gene active IGF-II.
In humans, activation of both IGF-II genes has been associated with a fivefold increase in the risk of intestinal tumors.
Working with mice genetically engineered to develop colon cancer, after researchers administered a drug that blocked the ability of cells to respond to the growth factor IGF-II. The mice developed 70 percent fewer precancerous lesions than mice that were not treated.
If this can be confirmed in humans, it could be something really emocionante.Esto means we might be able to do something about at-risk cells before cancer develops and treat these cells biochemically rather than using current drugs do not are specific and eliminate everything that comes down the road.
an investigation showed that the vaccine against human papilloma virus (HPV) also protects against vaginal and vulvar cancer.
It is known that HPV is responsible for most cases of cervical cancer, but this study suggests that it may be vaginal and vulval cancer. In fact, the papilloma virus was found in 80 percent of the six thousand cases of these cancers
Gardasil (trade name of the vaccine) was developed to protect against four variants of HPV, two of which (16 and 18) are associated with cervical cancer and vulvar cancers, the other two (6 and 11) cause anogenital lesions.
Merck (manufacturer of Gardasil).
After three years follow up, the vaccine proved 100 percent effective in protecting against lesions of the vulva and vagina. The drug was able to reduce the risk of vaginal and vulvar lesions, regardless of whether HPV was detected in the lesion.
* Vaccine Human Papilloma Virus
This virus, according to the World Health Organization, kill 800 women daily. During 2007, the discovery and commercialization of two vaccines against Human Papilloma Virus (HPV), gave hope.
* Stem cells, not embryonic
Reprogramming of human skin cells into stem cells to transform them resolved, at least in part, the ethical debate raised by the use of stem cells from human embryos product, research and medical treatments.
* A submarine that runs through the blood
In 2007 was really the use of nanoparticles led by remote control, travel through the bloodstream to reach the place where cancerous tumors. Then, they can serve two functions: confused with malignant cells and help to visualize tumors with magnetic resonance imaging, or go with the chemotherapy medicine and apply locally.
* Having cancer today is not the same as five years ago, nor will within one to five, since the prospect of cure, even prevention, is changing thanks to these advances positivamente.Y 50% of the definitely diagnosed cancers are cured.
* The identification of the sentinel node, which is closer to the tumor, allowing the removal of it without losing your breast. This totally changes the way in which the woman faces her illness. Furthermore, by not removing the axillary nodes avoids unpleasant side effects such as lymphedema, a chronic inflammation and irreversible arm.
* A mammogram is the most efficient technique for the diagnosis of breast cancer. Indeed, prevention campaigns have succeeded in reducing cancer mortality by 15% and 40% in women over 50 years.
* A NEW DRUG THAT PREVENTS THE TUMOR IS “food” and GROW
we are working with a drug that has proven effective in some blood cancers like myeloma. Its main objective is to attack the cancer cell microenvironment where they develop and feed, preventing, thus, angiogenesis (growth of tumor through blood vessels).
* The combination of two imaging techniques in one device, the PET (Positron Emission Tomography) and CT (Computed Tomography), to locate and identify suspicious lesions and tiny. Thus, operations to remove malignant lesions are much more accurate.
* A third of cancers (particularly breast, colon and esophagus) could be prevented with physical exercise combined with healthy eating.

A significant advance in the field of oncology is changing the meaning of palliative care and symptom control. Today, the context of this unit does not refer to the terminal patient but that is curable but which have side effects or disease treatment. Control of these symptoms is as important as treatment, and we want to cure but also help the patient’s quality of life is best.
According to Thomas released to Reuters, U.S. researchers said on Thursday that a blood test can detect traces of cancer, allowing to increase the likelihood of early detection, knowing the state you are in, if there is a relapse or if it has spread, which is considered a very effective tool in establishing the treatment of each patient, making interventions more precise.
The study was published in the journal Science Translational Medicine, which state that the test is based on the sequence of whole genomes. For during the investigation which took six samples of normal and cancerous tissue box colorectal cancer patients and two patients with breast cancer, and made a genetic map of each patient, looking for extra copies of DNA or chromosomes fused sections. Which leads to the recognition of approximately nine reorganisations in the genetic codes on average, in the cancer samples, which are not present in normal tissue, says Dr. Victor Velculescu of Johns Hopkins University.
It also affirmed the National Cancer Institute that since the recognition of certain genetic mutations linked to various cancers; it has been the identification of an inherited tendency to develop colon cancer and breast cancer: “(…) there is evidence commercially available to detect inherited susceptibility to these cancers.”
However, today the test is based on the rapid technological advances, making it a highly expensive and extensive work, considering a value of 5,000 dollars, however it is projected to decrease costs and concerns Dr. Volgelstein Johns Hopkins: “There is no doubt that in a couple of years will cost less than an MRI or CT scanner.”
Finally, it is important to note that during the last decade technological advances have enabled the creation of different genetic testing for early detection of various diseases, especially in people with a family history linked to such diseases, among which are various types of cancer. Thus, we find a new tool that can help not only prevention but also in tailoring therapy according to each clinical case.
Possible treatment with antibodies that could boost the immune system to help fight some cancers. The treatment has shown a significantly higher survival neuroblastoma, a type of childhood cancer – in laboratory tests, and hope it can eventually be used to treat children with this disease.
The antibodies did not work so well with more aggressive tumors, but researchers then joined one with a peptide, a protein fragment-specific, and together they destroyed between 40 and 60 percent of these tumors.
These antibodies are designed to acknowledge the response and stimulate the immune system, making more effective their attack on cancer cells, the researchers said. It is hoped that these antibodies can be used to reinforce or ‘overload’ the body’s immune system to help fight cancer. Although this work is still in pre-clinical stage, hopefully allowing us to identify a way in which we can offer an effective treatment for neuroblastoma immunotherapy. Neuroblastoma is a cancer that affects the development of nerve tissue and accounts for 15 percent of cancer deaths in children. About 60 percent of children with neuroblastoma can be cured with chemotherapy, but for those children who do not respond well to this treatment, immunotherapy could become a vital new option for treatment.
Immunotherapy is a relatively new form of treatment, but several monoclonal antibodies – proteins that can be tailored to detect the proteins attached to cancer cells and can be used to stop their growth – are already approved to treat adult cancers.
They discovered a new type of magnetic nanoparticles can be inserted nucleic acid in the body and slow the progression of cancer in mice.
This system provides better results than that used in gene therapy against cancer. Results are confirmed in humans, it would be a big step for the noninvasive treatment of different types of tumors.
The researchers then injected into the bloodstream of rodents magnetic nanoparticles composed of an optimized sequence of small RNA interference.
Once done, the nanoparticles led to the tumor and ribonucleic acid specially designed to “silence” the gene that causes tumor may reach their destination, and after eight injections, slowed its growth.
For years Cuba has one of the best health care systems and pharmacy in the world. In this Caribbean country has made great strides in finding a cure for cancer, and recently learned that a state laboratory will begin exporting a drug developed from the venom of a scorpion.
The product in question has been dubbed Vidatox, and the company responsible for its creation is Labiofam. According to specialists are needed more than 15 years of research to get this product so special. It should be noted that the drug has already been implemented in a number of cancer patients, achieve spectacular results.
The drug makers said that in addition to the antitumor properties Vidatox also has anti-inflammatory and analgesic powers. But we must mention that this is not a miracle cure but a product that serves to complement traditional therapy. The first countries to receive this medication will be Spain, Italy, Albania and India, among others.
Cancer is a disease that more patients suffering in the world and because of the different varieties that exist is very difficult to find specialists for cures. Yet progress remains constant. In the U.S., for example, a group of researchers working on a cure for pancreatic cancer.
For this kind of cancer specialists at the University of Pennsylvania decided to combine the traditional process of chemotherapy with a special drug that is used to activate a protein called CD40. This technique has given you some very interesting results among patients with incurable pancreatic cancer.
The “mixture” between chemotherapy and medication has allowed the progression of cancer (also known as pancreatic ductal adenocarcinoma) is stopped by a little over five months. Although still a lot of work is a process that generates a lot of hope among patients with the disease.
