New technology of cancer detecting needles

Cancer-detecting ‘smart needles’:

In this technology A “smart needle” has been developed by scientists within the UK which could speed up cancer detection and diagnosis times.Researchers believe the technology might be particularly helpful in diagnosing lymphoma, reducing patient anxiety as they await their results. at the present , people with suspected lymphoma often need to provide a sample of cells, followed by a biopsy of the node to be administered for a full diagnosis, a process which may be time consuming.The new device uses a way referred to as Raman spectroscopy to shine a low-power laser into the a part of the body being inspected, with the potential to identify concerns within seconds, scientists from the University of Exeter say.“The Raman smart needle can measure the molecular changes related to disease in tissues and cells at the top of the needle,” said professor Nick Stone, project lead, from the University of Exeter. “Provided we will reach a lump or bump of interest with the needle tip, we should always be ready to assess if it's healthy or not.”

The ''smart needle" probe, is comprised of fibre-optics encased within a fine needle which will search for cancer under the skin's surface—for example, in neck glands. Dr. John Day of the University of Bristol, who built the primary prototypes and continues to figure on optimising the planning , said, "If our probe is successful in clinical trials for lymphoma, then it opens the door to applying it to several other cancers within the body."Dr. Alex Dudgeon, a search Fellow in Biomedical Spectroscopy at the University of Exeter and a part of the research team said: "Early detection may be a key think about the successful treatment of cancers. this system has real potential to extend the speed of lymphoma diagnosis.""It could potentially bring huge advantages over traditional methods providing a moment diagnosis, reducing patient anxiety and it's going to eliminate the necessity for unnecessary diagnostic surgery. As a result, there are often a much-improved patient experience and significant cost and time savings for the NHS."Mr Charlie Hall, a Head and Neck Consultant at Gloucestershire Hospitals NHS Foundation Trust said: "This is an exciting project that has the potential to revolutionise our diagnostic approach to cancers occurring within the head and neck region. Early and accurate diagnosis is that the key to raised cancer treatment outcomes and can even have significant economic benefits to the broader NHS."

Cancer detection could become much quicker and easier within the future after scientists developed a replacement "smart needle" that uses a mini laser to spot diseased tissue within seconds.Researchers have demonstrated the technique works within the lab and have just begun a serious three-year clinical test to check it in living people.They have focused on lymphoma thus far but are hopeful the technique could even be wont to diagnose other sorts of the disease, like breast and prostatic adenocarcinoma , further down the road .
Cancer imposes an important societal burden worldwide, in terms of both epidemiology and costs. The introduction of more sophisticated imaging and diagnostic techniques and advanced drugs that specifically target tumor cells is resulting in increasingly expensive treatments, which can be affordable just for few patients. Prevention, and particularly primary prevention, is an efficient way of addressing the challenging issue of cancer, since between a 3rd and a half cancers might be prevented on the idea of our current knowledge of risk factors. Moreover, prevention is cost-effective, its effects aren't limited to high-risk subjects but reach the whole population, and it's not hooked in to socioeconomic status. Regulatory measures can have a broad impact, even on future generations; by empowering and educating subjects, promoting healthy behaviours and teaching self-care, they will trigger a virtuous cycle. In recent decades, oncology has shifted from being merely reactive to being proactive; this shift has led to the event of so-called "P4 medicine", where the 4 Ps represent "preventive", "predictive", "personalized" and "participatory". Prevention programs are a crucial a part of the trouble to regulate cancer, as they're ready to reduce both the incidence of cancer and mortality. as an example , screening for colorectal, breast and cervical cancer is reducing the burden of those common tumors. Anti-cancer vaccines, both prophylactic and therapeutic, constitute another important preventive tool. Although progress has been made in these areas, much remains to be done. With reference to screening programs, coverage might be increased by introducing new, more acceptable, less invasive tests, stratifying screening through correlation with anamnestic, clinical, radiological and genomic data (so-called "populationbased personalized cancer screening"), and exploiting new information and communication technologies, like smartphone applications or personalized text messages (so-called "screening 2.0"). Advocacy and proposals by physicians also can play a task , therein eligible subjects got to be ready to discuss their doubts and their perceived psycho-social barriers. However, new screening initiatives should be implemented only after a careful health technology assessment has been performed within the framework of evidence-based medicine, organized screening programs are strengthened and opportunistic or spontaneous programs are limited.
