3D printing allows researchers to create models of tumor tissue that more accurately repli...

Medical research is only as good as the model, whether you’re using one animal to stand in for another, or creating in vitro replicas of tissue and organs. A research lab at Drexel University specializing in biofabrication recently used 3D printing to create models of tumor tissue that more closely replicate real tumors than traditional 2D tissue culture. Appropriating tools in this manner could lead to a better understanding of how tumors grow, and importantly, how they die.  Read More

While many animals face extinction due to poaching or loss of habitat, Tasmanian devil numbers are sbeing dramatically reduced due to a contagious tumor with a mortality rate of 100 percent. Called Devil Facial Tumor Disease (DFTD), it kills the animal in a matter of months. Now fresh research from the University of Cambridge has delivered new data on the mechanism of the disease which could increase the chances of developing a vaccine.  Read More

The BSE bra being developed by First Warning Systems would continuously monitor the wearer...

We’ve previously seen bras that monitor a wearer’s heart rate, double as an emergency facemask, or help women search for a husband. But the BSE (breast self exam) bra being developed by First Warning Systems looks to be the best bit of added functionality for the support undergarment we’ve come across yet. Using sensors integrated into the cups, the bra looks for the slight variations in temperature on the surface of the breast that can indicate a tumor growing within.  Read More

In addition to an MRI (pictured), gold nanoparticles allow a brain tumor to be imaged phot...

Scientists at Stanford University’s School of Medicine have created nanoparticles that are able to precisely highlight brain tumors. Because the nanoparticles can be imaged in three different ways, they can be used to delineate the boundaries of tumors before and during brain surgery to ease the complete removal of tumors. The scientists have already used the nanoparticles to remove brain tumors from mice with unprecedented accuracy and hope the technique could be used on humans in the future.  Read More

The NovoTTF treatment involves placing pads onto the patient's skin that creates a low int...

The FDA (US Food and Drug Administration) has approved a new treatment for patients as an alternative to chemotherapy. The promising new non-invasive treatment by Novocure uses "Tumor Treating Fields" (NovoTTF) to treat cancerous growths and is now available for adult patients with recurring brain tumors (recurrent glioblastoma or GBM). The treatment delivers electric fields to a patient utilizing a portable, wearable device that permits the patient to maintain normal daily activities without down time.  Read More

Some cancers, such as pancreatic and cervical cancers, are notoriously hypoxic, which means they contain low oxygen levels. Because radiation therapy needs oxygen to be effective, hypoxic areas of a tumor can be difficult to kill. To combat this, researchers at Purdue University have developed and tested a miniature electronic device that is designed to be implanted into solid tumors to generate oxygen and boost the effectiveness of radiation and chemotherapy treatments.  Read More

Newly designed nanoparticles can quickly locate a tumor, then set off a chemical reaction ...

To minimize the toxic effects of chemotherapy, many researchers have been working to develop nanoparticles that that deliver drugs directly to tumors. But researchers at MIT claim that even the best of these nanoparticles are typically only able to deliver about one percent of the drug to their intended target. Now, a team has developed a new delivery system that sees a first wave of nanoparticles homing in on a tumor that then calls in a larger second wave that dispenses the cancer drug. In a mouse study, the new approach was found to boost drug delivery to tumors by over 40-fold.  Read More

Not many things are tougher than dealing with a diagnosis of cancer. But often the protracted wait for biopsy results, and the uncertainty surrounding them, can be excruciating for patients and their loved ones. Now a research team at the University of Illinois has developed a tissue-imaging technique that produces easily identifiable, color-coded images of body tissue that clearly outline tumor boundaries. What’s more, the process takes less than five minutes.  Read More

Nano-scale disturbances in cheek cells indicate the presence of lung cancer.  Image by: Zi...

Early detection of lung cancer is vital for increasing a patient’s survival rate and to prescribe the best form of treatment. Now New York researchers have developed an early detection method involving a simple cheek swab. Called partial wave spectroscopic (PWS) microscopy, this new technique involves shining diffuse light on cells from the swab. The test is able to distinguish individuals with or without lung cancer, even if the patient has been a lifelong smoker or suffers from other smoking related illnesses.  Read More

The 3D high clarity image of melanoma produced using the new imaging technique

Even though melanoma is one of the less common types of skin cancer, it accounts for the majority of skin cancer deaths – around 75 percent. The five-year survival rate for early stage melanoma is very high (98 percent), but the rate drops precipitously if the cancer is detected late or there is recurrence. So a great deal rides on the accuracy of the initial surgery, where the goal is to remove as little tissue as possible while obtaining “clean margins” all around the tumor. So far no imaging technique has been up to the task of defining the melanoma's boundaries accurately enough to guide surgery – until now.  Read More
