New cancer-scanning technology reveals a previously unknown detail of human anatomy.
- Scientists using new scanning technology and hunting for prostate tumors get a surprise.
- Behind the nasopharynx is a set of salivary glands that no one knew about.
- Finding the glands may allow for more complication-free radiation therapies.

A <a href="https://www.cancer.gov/news-events/cancer-currents-blog/2020/prostate-cancer-psma-pet-ct-metastasis" target="_blank" rel="noopener noreferrer">study</a> published last spring suggests it may be the most accurate way to diagnose prostate cancer metastasis than any method previously available.</p><p>Prior to PSMA PET/CT, the primary way to look for metastatic prostate cancer was to image the body using x-ray-based CT scans and to perform bone scans, since bone is where prostate cancer often spreads. CT scans, however, often miss small tumors, and bone scans can generate false positives as a result of other damage or abnormalities that have nothing to do with prostate cancer.</p><p>PSMA PET/CT scans track the travels of an intravenously administered radioactive glucose tracer throughout the body. For hunting down prostate cancer, this tracer contains a molecule that binds to the <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC1472940/" target="_blank">PSMA</a> protein that's present in large amounts in prostate tumors. The molecule is linked to a radioisotope, <a href="https://netrf.org/2018/11/13/gallium-68-scan-for-neuroendocrine-tumors/" target="_blank" rel="noopener noreferrer">gallium-68</a> (Ga-68).</p><p>In last spring's research, PSAM PET/CT was shown to be 27 percent more accurate than previous methods at finding metastases (92 percent accuracy as opposed to 65 percent). In addition, it was found to be much less likely to produce false positives, and it was particularly good at detecting tumors far removed from the prostate.</p>
A good kind of avoidance behavior<p>"Radiation therapy can damage the salivary glands," says Vogel, "which may lead to complications. Patients may have trouble eating, swallowing, or speaking, which can be a real burden."</p><p>The researchers looked back through the cases of 723 patients who had undergone radiation treatment, interested in seeing if inadvertent radiation of the tubarial glands was associated with the complications experienced by the patients. It turned out that this <em>was</em> the case: In cases where more radiation had been delivered to this area, patients did indeed report more in the way of complications of the type one would expect when salivary glands are radiated.</p><p>Now that we know the tubarial salivary glands exist, therapists can stay out of their way. Vogel says, "For most patients, it should technically be possible to avoid delivering radiation to this newly discovered location of the salivary gland system in the same way we try to spare known glands."</p><p>He's hopeful that that things may be about to get at least a bit better for cancer patients: "Our next step is to find out how we can best spare these new glands and in which patients. If we can do this, patients may experience less side effects which will benefit their overall quality of life after treatment."</p>
Researchers from the University of Toronto published a new map of cancer cells' genetic defenses against treatment.

Attempting to address potential cancer-cell vulnerabilities across these variations is a life-or-death game of whack-a-mole.</p><p>"It's an ongoing battle between the immune system and cancer, where the immune system is trying to find and kill the cancer whereas the cancer's job is to evade that killing," says Moffat.</p>

Credit: National Cancer Institute/Unsplash<p>Moffat and his colleagues decided to investigate and identify genes within cancer cells that help them defeat treatment. Co-lead author Keith Lawson of Moffat's lab explains that "it's important to not just find genes that can regulate immune evasion in one model of cancer, but what you really want are to find those genes that you can manipulate in cancer cells across many models because those are going to make the best therapeutic targets."</p><p>To accomplish this, the researchers, working with scientists at <a href="https://www.agios.com" target="_blank">Agios Pharmaceuticals</a> in Cambridge, Massachusetts, first exposed cells from breast, colon, kidney and skin cancer tumors to T cells in lab dishes. This established a baseline of their responses to treatment. Next, using CRISPR, the scientists went through the cells, exhaustively turning off one gene at a time to determine its role in immunotherapy resistance by comparing the cells' response to the T cells compared to their original baseline response.</p><p>The team identified 182 "core cancer intrinsic immune evasion genes" that affected the cells' response to T cells. The fact that some of the identified genes were already known to be involved in resistance provided the researchers with some confidence that they were on the right track.</p><p>Still, many of the genes they ID'ed had not been previously implicated. "That was really exciting to see because it means that our dataset was very rich in new biological information," says Lawson.</p>
It's complicated<p>Unfortunately, Moffat's research also makes clear that defeating cancer-cell resistance is not as simple as removing certain genes. It's true that when the team switched off some of the genes they'd identified, the cancer cells became more vulnerable to T cells, but on the other hand, removal of some other genes made the cancer cells more resistant.</p><p>There also appear to be relationships between multiple genes that complicate matters. </p><p>The team explored the manipulation of the genes that allow cancer cells to engage in <a href="https://en.wikipedia.org/wiki/Autophagy" target="_blank">autophagy</a>, the process by which cells clear out no-longer useful materials to facilitate speedy recovery from damage. Surprisingly, when the researchers deleted certain genes responsible for cancer cells' autophagy, they found the cells' resistance to T cells increased. Apparently, removing one autophagy gene strengthened another mutated autophagy gene.</p><p>"We found this complete inversion of gene dependency," said Moffat. "We did not anticipate this at all. What it shows us is that genetic context — what mutations are present — very much dictates whether the introduction of the second mutation will cause no effect, resistance or sensitivity to therapy."</p><p>There remains a long road ahead when it comes to unraveling cancer cells' resistance to immunotherapy. However, this new study presents a new map that can help scientists navigate what comes next.</p>
A large-scale study from King's College London explores the link between genetics and sun-seeking behaviors.
- There are a number of physical and mental health benefits to sun exposure, such as boosted vitamin D and serotonin levels and stronger bones.
- Addictions are multi-step conditions that, by definition, require exposure to the addictive agent and have also been proven to have a genetic factor. Countless people are exposed to addictive things, but not all become addicted. This is because of the genetic component of addiction.
- This large-scale study explores the link between sun-seeking behaviors and the genetic markers for addiction.

The mental and physical health benefits of sunlight have been heavily researched.
Credit: eldar nurkovic on Shutterstock<p>The benefits of sunlight have been widely discussed for many years. In fact, there are a number of physical and mental health benefits to sun exposure.</p><p><strong>Sunshine (and the lack of) impacts your hormone levels. </strong></p><p>Sunlight (and alternatively, the lack of sunlight) triggers the release of certain hormones in your brain. Exposure to sunlight is thought to increase serotonin, which is associated with boosting your mood and helping you feel calm and focused. </p><p>Alternatively, dark lighting triggers melatonin, a hormone that is helpful in allowing you to rest and fall asleep. Without enough sunlight, your serotonin levels can dip - and low serotonin levels have been associated with a higher risk of major depression with seasonal pattern (formerly known as seasonal affective disorder).</p><p><strong>Sunlight can build strong bones. </strong></p><p>Exposure to the ultraviolet-B radiation in the sun's rays can interact with your skin, causing it to create vitamin D. <a href="https://www.nhs.uk/conditions/vitamins-and-minerals/vitamin-d/" target="_blank" rel="noopener noreferrer">According to NHS</a>, vitamin D helps regulate the amount of calcium and phosphate in the body. A lack of vitamin D can lead to bone deformities or bone pain. <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2290997/" target="_blank" rel="noopener noreferrer">A 2008 study</a> has shown that even 30 minutes in sunlight (while wearing a bathing suit) can boost vitamin D levels. </p><p><strong>Can sunlight actually prevent cancer? </strong></p><p>Although heavy exposure to sunlight has been proven to contribute to certain skin cancers, a moderate amount of sunlight has actually been shown to have preventative benefits.</p><p><a href="https://cjasn.asnjournals.org/content/3/5/1548.full" target="_blank" rel="noopener noreferrer">According to a 2008 study</a> from the Clinical Journal of the American Society of Nephrology, those who live in areas with fewer daylight hours are more likely to have some specific cancers (including but not limited to colon cancer, ovarian cancer, and prostate cancer) than those who live in areas with increased daylight hours.</p><p><strong>Additionally, sunlight has been shown to help people with skin conditions such as psoriasis. </strong></p><p><a href="http://www.who.int/uv/faq/uvhealtfac/en/index1.html" target="_blank" rel="noopener noreferrer">According to the World Health Organization</a>, sun exposure may also be able to help treat skin conditions such as psoriasis, eczema, jaundice, and acne. <a href="https://www.healthline.com/health/depression/benefits-sunlight#benefits" target="_blank" rel="noopener noreferrer">Some research</a> has also indicated the sun benefits people who struggle with rheumatoid arthritis (RA), systemic lupus erythematosus, and inflammatory bowel disease. </p>
Can you be addicted to the sun?<img type="lazy-image" data-runner-src="https://assets.rebelmouse.io/eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJpbWFnZSI6Imh0dHBzOi8vYXNzZXRzLnJibC5tcy8yNDQyMjI1Ny9vcmlnaW4uanBnIiwiZXhwaXJlc19hdCI6MTY2NjI2NzMwOX0.rB2IFcqqFIwqCn1TF-Upv9_O3KlmI_H4MtYx6L7bTqI/img.jpg?width=1245&coordinates=31%2C0%2C32%2C0&height=700" id="eb0cc" class="rm-shortcode" data-rm-shortcode-id="384e08fdcd535ed2b792eef419af9e2c" data-rm-shortcode-name="rebelmouse-image" alt="hands holding up the sun" />
The large-scale study examines the link between addiction and sunlight, with some surprising results...
Credit: KieferPix on Shutterstock<p>Addictions are multi-step conditions that, by definition, require exposure to the addictive agent. Due to the increase of serotonin (a chemical in the human body <a href="https://www.healthline.com/health/mental-health/serotonin" target="_blank">that has been proven</a> to help reduce depression, regulate anxiety, and maintain bone health), it's natural that being exposed to prolonged periods of sunlight could become somewhat addictive to the human body and mind. We crave things that make us feel good, and sometimes those cravings become something we depend on. This is the very nature of addiction.</p><p>Countless people are exposed to addictive things (substances, medications, and yes, even the sun), but not all become addicted. This is because of the <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3506170/" target="_blank" rel="noopener noreferrer">genetic component of addiction</a>. </p><p>A large-scale study from King's College in London examines more than 260,000 people to better understand how sun-seeking behavior in humans can be linked to genes involving addiction, behavior traits, and brain function. </p><p><strong>The study included two phases:</strong></p><p>Phase one suggested genetics play a role in sun-seeking behaviors and phase 2 helped pinpoint what those genetic markers are.</p><p>Phase 1: The researchers studied the detailed health information of 2,500 twins, including their sun-seeking behavior and their genetics. Identical twins in a pair were more likely to have similar sun-seeking behavior than non-identical twins, indicating that genetics plays a role here. </p><p>Phase 2: The team of researchers then were able to identify five key gene markers involved in this sun-seeking behavior from further analysis of 260,000 participants. Some of the genes indicated have been linked to behaviors traits that are associated with risk-taking and addiction (including smoking and alcohol consumption).</p><p><strong>What does this study really prove? </strong></p><p>Some may think it's natural to become addicted to something that makes you feel good. The physical and mental health benefits of the outdoors have been heavily studied...so what does this study really mean? </p><p>First and foremost, it means more research needs to be done to examine the link between human conditions and exposure to sunlight. Senior author Dr. Mario Falchi explains to the <a href="https://www.kcl.ac.uk/news/addicted-to-the-sun-its-in-your-genes" target="_blank">King's College London News Center</a>: "Our results suggest that tackling excessive sun exposure or use of tanning beds might be more challenging than expected, as it is influenced by genetic factors. It is important for the public to be aware of this predisposition, as it could make people more mindful of their behavior and the potential harms of excessive sun exposure."</p><p>Additionally, it could mean alternative treatments, and further research needs to be conducted in terms of how we treat certain conditions that are caused or heavily influenced by human exposure to sunlight. </p>
An active component of honeybee venom rapidly killed two particularly aggressive forms of breast cancer in a laboratory study.
- New laboratory studies by a team of scientists found that the active component of honeybee venom induced death in two forms of malignant breast cancer cells that are notoriously difficult to treat.
- The magic healing molecule in the honeybees' venom appears to be melittin, which rapidly killed cancer cells in under an hour.
- In the future, doctors could potentially use melittin alongside chemotherapy drugs to increase the efficacy of the treatment.
The magic molecule<p>Previously, honeybee venom has shown potential in treating other medical conditions such as <a href="https://www.sciencealert.com/mellitin-bee-venom-eczema-inflammation-treatment" target="_blank" rel="noopener noreferrer">eczema</a> and tumors, and it has been known to <a href="https://www.sciencedirect.com/science/article/abs/pii/S0041010108003796?via%3Dihub" target="_blank" rel="noopener noreferrer">have anticancer properties</a>. How the venom works against tumors on a molecular level hasn't been understood, but science just got a lot closer. </p><p>It seems that the magic healing ingredient in the honeybees' venom is melittin — the zingy molecule responsible for producing the painful sting of a bee. Scientists at the Harry Perkins Institute of Medical Research in Perth, Australia and the University of Western Australia found that the melittin induced cancer cell death. </p><p>Their lab study, reported in the journal <a href="https://www.nature.com/articles/s41698-020-00129-0" target="_blank" rel="noopener noreferrer">NPJ Precision Oncology</a>, is the first to have looked into the effect the ingredient has on a range of breast cancers, the most common cancer in women worldwide. The two most aggressive and hard-to-treat types are known as triple-negative breast cancer (TNBC) and HER2-enriched breast cancer, which tend to mutate to resist existing treatments. The researchers found that melittin rapidly kills these cancer types and, critically, does so with no negative effects on normal cells. </p><p>"The venom was extremely potent," <a href="https://www.perkins.org.au/honeybee-venom-kills-breast-cancer-cells/" target="_blank" rel="noopener noreferrer">said</a> research leader Ciara Duffy from The Harry Perkins Institute of Medical Research in a news release. "We found that melittin can completely destroy cancer cell membranes within 60 minutes."</p><p>The lab study also found that bumblebee venom (which does not contain melittin) did not kill those particular breast cancer cells.</p>
How it works<span style="display:block;position:relative;padding-top:56.25%;" class="rm-shortcode" data-rm-shortcode-id="df37e6f56c59da163c4ed2df27444ee7"><iframe type="lazy-iframe" data-runner-src="https://www.youtube.com/embed/K3oMN1a_pdg?rel=0" width="100%" height="auto" frameborder="0" scrolling="no" style="position:absolute;top:0;left:0;width:100%;height:100%;"></iframe></span><p>Melittin disarms cancer cells by puncturing holes in their outer membrane. Another stunning effect: within just 20 minutes of exposure to melittin, the chemical messages cancer cells need to grow and divide are disrupted.</p><p>"We looked at how honeybee venom and melittin affect the cancer signaling pathways, the chemical messages that are fundamental for cancer cell growth and reproduction, and we found that very quickly these signaling pathways were shut down," <a href="https://www.perkins.org.au/honeybee-venom-kills-breast-cancer-cells/" target="_blank" rel="noopener noreferrer">said Duffy</a>.</p><p>The molecule is able to do this by stopping the activation of receptors that signal growth factors in the cells' membranes. The large number of these receptors in HER2-enriched cancer cells and some TNBC cells is one reason for their uncontrollable growth. Melittin seems to halt the cell's proliferation by blocking those growth signals from getting through. </p><p>"Significantly, this study demonstrates how melittin interferes with signalling pathways within breast cancer cells to reduce cell replication," said Western Australia's Chief Scientist Professor Peter Klinken. "It provides another wonderful example of where compounds in nature can be used to treat human diseases."</p>
Enhancing current cancer treatments<p>The team also tested to see if melittin could be used with existing chemotherapy drugs, as the pores in the membranes that it creates may allow other treatments to faster penetrate and kill cancer cells. </p><p>They tested the idea on a lab mouse with triple-negative breast cancer. They injected it with a combination of melittin and docetaxel — a drug used to treat a number of cancers including breast cancer. The mixture proved to be more effective at shrinking the tumors than either melittin or docetaxel alone. </p><p>In the future, doctors could potentially use melittin alongside chemotherapy drugs to enhance the efficacy of the treatment. This may allow them to reduce the dosage of chemotherapy drugs, and the adverse side effects that come with it. </p><p>The authors in the study point out that honeybee venom is inexpensive and easy to obtain, thus making it a fantastic option for cancer treatment in regions and countries with poorly resourced health services and care.</p><p>"Honeybee venom is available globally and offers cost effective and easily accessible treatment options in remote or less developed regions," <a href="https://www.nature.com/articles/s41698-020-00129-0" target="_blank" rel="noopener noreferrer">the authors write.</a> "Further research will be required to assess whether the venom of some genotypes of bees has more potent or specific anticancer activities, which could then be exploited."</p><p>Though exciting, this research is still in early, lab testing stages. The researchers will still need to perform clinical trials to assess the safety and efficacy of melittin for treating breast cancer in humans.</p>

While all cancers are terrible, she says people are especially unlikely to discuss colon cancer—and that needs to change. Colorectal cancers are predicted to increase by 90 percent by 2030. She advises broader discussions on this topic, an especially important point as she didn't take her own symptoms seriously for two years. Her gastroenterologist discovered a sizable tumor after she finally agreed to a colonoscopy. </p><p>Incredibly, a connection in Hollywood helped her change her perspective on cancer. This connection never told anyone about her own struggle with colon cancer because "she would be blackballed from jobs, written off as unreliable and sickly, even though she continued to work long hours around her treatments." In fact, she lost a big job after someone discovered her cancer. Stewart continues, </p><p style="margin-left: 20px;">"Is it any wonder that Boseman, with his meteoric rise to fame and the responsibility of being one of the preeminent faces of Black empowerment in Hollywood and beyond, didn't share his diagnosis publicly?"</p><p>Fabian Alsultany has worked in the music industry for over a quarter-century, and he did not remain quiet about his struggle with colon cancer 2B—a tumor perforated his colon. A surgery to remove the tumor (and cut out inches of his colon) and six months of chemotherapy <a href="https://riseupeight.org/how-to-succeed-in-music-overcoming-cancer/" target="_blank">left him exhausted</a>.</p><p style="margin-left: 20px;">"My reality was existing in a two-week cycle of death and rebirth. I experienced every side effect in the book: extreme nausea, neuropathy, dizziness, loss of appetite, hair loss, inability to hold any food in…you get the point: it was miserable. I was fortunate to have my family and friends around me through it all."</p><p>Fortunately, Alsultany was able to confide in those around him. He also documented his cancer journey through <a href="http://alsultany32.blogspot.com/" target="_blank">his blog</a>. While he's an outspoken advocate for discussing cancer, not everyone feels safe in this regard. </p><p>Social connections are especially important when struggling with cancer. Hopefully, the ridiculous stigma around cancer, as evidenced in Stewart's writing above, will end with Boseman's death.
