"Everybody has a different amount of fibroglandular tissue and a different pattern," Freer said, referring to dense breast tissue. In individual interviews as part of Gunn's survey, six out of 61 women said dense breasts contributed to breast cancer risk. There are two reasons dense breasts are linked to a higher risk of breast cancer. To lower one's risk of breast cancer overall, doctors recommend limiting alcohol intake, exercising regularly and maintaining a healthy diet. The Breast Cancer Surveillance Consortium offers an online tool to help people gauge their breast cancer risk based on multiple factors, including breast density.

CAIRO — Known as Egypt’s “golden boy,” the mummified remains of a teenager buried 2,300 years ago have long remained shrouded in mystery. Now they have been “digitally unwrapped” by scientists, revealing intimate details that went undiscovered for over a century. Radiologists at Cairo University in Egypt used CT scans to non-invasively unwrap the remains, uncovering signs of wealth as well as efforts to ensure his safe passage to the afterlife. Amulets were both placed inside the “golden boy” and between the wrappings used to mummify the remains, the study published Tuesday found. The new study comes as museums in the U.K. reckon with whether the term "mummy" is appropriate to describe mummified remains, because of what some say are its “dehumanizing” connotations.

☆ An AI bot scored nearly as well as doctors on a radiology exam — but it's not ready to replace humans yet

An AI bot took the exam radiologists in the UK have to pass before finishing training. The AI candidate passed two of 10 mock exams, while humans passed four of 10. The AI candidate was a Smarturgences tool developed by French AI company Milvue that is commercially available. The AI candidate needs more training analyzing areas that are considered 'non-interpretable' like the abdomen and axial skeleton. While the AI candidate had "relatively high" accuracy, it was only the highest scoring candidate for one of the mock exams.

☆ Fact Check-No evidence COVID-19 vaccines cause ‘turbo cancer’

A video in which a Canadian doctor claims that COVID-19 vaccines cause so-called “turbo cancer” is not based on facts, according to five experts who spoke to Reuters. He claimed that COVID-19 vaccines damage the immune systems of recipients and cause aggressive new cancers, as well as flare-ups in those in remission from the disease. During the same period, the charity estimated that 30,000 fewer people began their cancer treatment compared to 2019 (here). Reuters has previously addressed claims where COVID-19 vaccines have been falsely linked to weakening the immune system (here), and causing cancer (here and here). Five experts told Reuters that there is no evidence to suggest COVID-19 vaccines cause cancer, nor so-called “turbo cancer,” but said a drop in screenings during the pandemic may have led to rise in cancers first detected at their later stages.

☆ Early research suggests promising use of AI to predict risk of heart attack or stroke using a single chest X-ray

CNN —Early research suggests a promising use of artificial intelligence to predict the 10-year risk of death from a heart attack or stroke from a single chest X-ray. The AI model uses the same risk thresholds as the established risk calculator, and early findings suggest that it works just as well. Sometimes, the AI findings align with a traditional radiology reading, but other times, it picks up on things that may have been missed, he said. He was not involved in the new AI research but says it’s important to keep the field moving forward. “The risk calculator is one part of risk assessment, but it’s not the only part.

☆ Meet Prenuvo, a company that says its whole-body MRI scan can detect the earliest stages of disease. Experts say it could do more harm than good.

Prenuvo, a company offering preventive MRI scans, raised a $70 million Series A in October. Some say healthy people probably don't need whole-body scans, which can lead to risky procedures. On October 18, the company, based in Vancouver, British Columbia, said it had raised a $70 million Series A to provide whole-body MRI scans to consumers. The website says the scans are performed by MRI technologists and analyzed by radiologists trained to read Prenuvo scans. PrenuvoWhole-body MRI scans aren't accessible for everyoneSafavi said whole-body MRI scans have been available for more than two decades for people curious about what might be in their bodies undetected.

Even in their first efforts, the GAN images were quickly on par with those made by any other, less intelligent software. You can find the results on the Generated Photos site, where you can filter by ethnicity, age, sex, eye color, and other attributes. Generated Photos' GANs tend to match conventional beauty standards, a product of the models that have been fed to the software. I'm not sure anyone would be surprised to find fake images accompanying testimonials on an Estonian bitcoin exchange or an online CBD seller. Are they real people deploying fake images, or fake people deploying fake images?

☆ Medical-imaging startup NVision says its quantum tech is a big step forward for catching cancerous tumors. Check out the 18-slide deck used to raise a $17 million grant.

Ulm-based NVision uses quantum tech to enable MRI scanners to analyse tumors at tissue level. The startup has partnered with Siemens to use its medical-imaging technology for cancer treatments. It secured a $17 million grant from the German government using this 18-slide pitch deck. Currently, MRI scanners can only conduct imaging at an anatomical level. "We know that with cancer, tumors have different metabolisms, and this is how they keep themselves alive," said CEO Sella Brosh.

☆ Fact Check-Cancerous tumours are not the body’s attempt to heal itself
▼ + stars: | 2022-09-16 | by ( Reuters Fact Check | ) www.reuters.com time to read: +4 min

Cancerous tumours are not the body’s attempt to heal itself, as has been claimed online. According to Cancer Research UK (here), cancer cells survive by sending out signals that encourage new blood vessels to grow into the tumour so it too can grow. The charity also reports that there were 9.6 million deaths from cancer worldwide in 2018 (here) and 167,142 deaths in the U.K. between 2017 and 2019 (here). Additionally, not all cancers form solid tumours, according to the U.S. National Cancer Institute (here), e.g., cancers of the blood, such as leukemias. Cancerous tumours are not the body’s process of trying to heal itself.
