AI May Be Better at Identifying Skin Cancer Than Human Doctors

Screening for skin cancer is an imperfect science, but an international team of scientists believes AI can help boost the test's accuracy. As they report in a study published in the Annals of Oncology, a machine-learning program known as a deep learning convolutional neural network (CNN) can be trained to recognize skin cancer with a greater success rate than professional dermatologists.

Researchers taught the CNN to identify skin cancer by showing it more than 100,000 images of malignant melanomas and benign moles. "The CNN works like the brain of a child," co-author Holger Haenssle, senior managing physician at the University of Heidelberg, said in a statement. That means the more information it's given about a certain task, the more it can learn and fine-tune its performance.

After training the AI with a database of images, the researchers showed it a different set of images it had never seen before. The CNN correctly diagnosed skin cancer from images alone 95 percent of the time. When 58 dermatologists were given the same task, the were able to catch only 86.6 percent of the malignant melanomas. The CNN was also less likely to misdiagnose a benign mole as cancerous.

The results don't necessarily mean that AI robots will be replacing flesh-and-blood doctors (or even pigeons) for cancer screenings in the near future. Rather, the researchers see the program acting as a supplement to dermatologists in the clinic, perhaps by evaluating images already stored in the doctors' databases and generating "expert opinions" on the likelihood of cancer.

Even as a doctor's aid, the CNN in its current state leaves room for improvement: The images it looked at were mostly of white patients that didn't include the full range of skin lesions. Diagnosing melanomas that show up on fingers, toes, and scalps also presents a challenge when working with an image-based system. Nonetheless, the researchers are confident that these issues won't stop AI from playing a role in future cancer screenings. "Given exponential development of imaging technology, we envisage that sooner than later, automated diagnosis will change the diagnostic paradigm in dermatology," researchers said. 

12 Creative Ways to Spend Your FSA Money Before the Deadline

If you have a Flexible Spending Account (FSA), chances are, time is running out for you to use that cash. Depending on your employer’s rules, if you don’t spend your FSA money by the end of the grace period, you potentially lose some of it. Lost cash is never a good thing.

For those unfamiliar, an FSA is an employer-sponsored spending account. You deposit pre-tax dollars into the account, and you can spend that money on a number of health care expenses. It’s kind of like a Health Savings Account (HSA), but with a few big differences—namely, your HSA funds roll over from year to year, so there’s no deadline to spend it all. With an FSA, though, most of your funds expire at the end of the year. Bummer.

The good news is: The law allows employers to roll $500 over into the new year and also offer a grace period of up to two and a half months to use that cash (March 15). Depending on your employer, you might not even have that long, though. The deadline is fast approaching for many account holders, so if you have to use your FSA money soon, here are a handful of creative ways to spend it.

1. Buy some new shades.

Head to the optometrist, get an eye prescription, then use your FSA funds to buy some new specs or shades. Contact lenses and solution are also covered.

You can also buy reading glasses with your FSA money, and you don’t even need a prescription.

2. Try acupuncture.

Scientists are divided on the efficacy of acupuncture, but some studies show it’s useful for treating chronic pain, arthritis, and even depression. If you’ve been curious about the treatment, now's a good time to try it: Your FSA money will cover acupuncture sessions in some cases. You can even buy an acupressure mat without a prescription.

If you’d rather go to a chiropractor, your FSA funds cover those visits, too.

3. Stock up on staples.

If you’re running low on standard over-the-counter meds, good news: Most of them are FSA-eligible. This includes headache medicine, pain relievers, antacids, heartburn meds, and anything else your heart (or other parts of your body) desires.

There’s one big caveat, though: Most of these require a prescription in order to be eligible, so you may have to make an appointment with your doctor first. The FSA store tells you which over-the-counter items require a prescription.

4. Treat your feet.

Give your feet a break with a pair of massaging gel shoe inserts. They’re FSA-eligible, along with a few other foot care products, including arch braces, toe cushions, and callus trimmers.

In some cases, foot massagers or circulators may be covered, too. For example, here’s one that’s available via the FSA store, no prescription necessary.

5. Get clear skin.

Yep—acne treatments, toner, and other skin care products are all eligible for FSA spending. Again, most of these require a prescription for reimbursement, but don’t let that deter you. Your doctor is familiar with the rules and you shouldn’t have trouble getting a prescription. And, as WageWorks points out, your prescription also lasts for a year. Check the rules of your FSA plan to see if you need a separate prescription for each item, or if you can include multiple products or drug categories on a single prescription.

While we’re on the topic of faces, lip balm is another great way to spend your FSA funds—and you don’t need a prescription for that. There’s also no prescription necessary for this vibrating face massager.

6. Fill your medicine cabinet.

If your medicine cabinet is getting bare, or you don’t have one to begin with, stock it with a handful of FSA-eligible items. Here are some items that don’t require a prescription:

You can also stock up on first aid kits. You don’t need a prescription to buy those, and many of them come with pain relievers and other medicine.

7. Make sure you’re covered in the bedroom.

Condoms are FSA-eligible, and so are pregnancy tests, monitors, and fertility kits. Female contraceptives are also covered when you have a prescription.

8. Prepare for your upcoming vacation.

If you have a vacation planned this year, use your FSA money to stock up on trip essentials. For example:

9. Get a better night’s sleep.

If you have trouble sleeping, sleep aids are eligible, though you’ll need a prescription. If you want to try a sleep mask, many of them are eligible without a prescription. For example, there’s this relaxing sleep mask and this thermal eye mask.

For those nights you’re sleeping off a cold or flu, a vaporizer can make a big difference, and those are eligible, too (no prescription required). Bed warmers like this one are often covered, too.

Your FSA funds likely cover more than you realize, so if you have to use them up by the deadline, get creative. This list should help you get started, and many drugstores will tell you which items are FSA-eligible when you shop online.

10. Go to the dentist.

While basics like toothpaste and cosmetic procedures like whitening treatments aren’t FSA eligible, most of the expenses you incur at your dentist’s office are. That includes co-pays and deductibles as well as fees for cleanings, x-rays, fillings, and even the cost of braces. There are also some products you can buy over-the-counter without ever visiting the dentist. Some mouthguards that prevent you from grinding your teeth at night are eligible, as are cleaning solutions for retainers and dentures.

11. Try some new gadgets.

If you still have some extra cash to burn, it’s a great time to try some expensive high-tech devices that you’ve been curious about but might not otherwise want to splurge on. The list includes light therapy treatments for acne, vibrating nausea relief bands, electrical stimulation devices for chronic pain, cloud-connected stethoscopes, and smart thermometers.

12. Head to Amazon.

There are plenty of FSA-eligible items available on Amazon, including items for foot health, cold and allergy medication, eye care, and first-aid kits. Find out more details on how to spend your FSA money on Amazon here.

Starbucks is showing its support for those individuals on the front lines of the fight against COVID-19 this holiday season by giving the gift of free coffee—all month long.

From now through December 31, any health care worker or other frontline worker can get a tall hot or iced coffee whenever they stop by Starbucks. The offer extends to just about anybody in a medical profession, including doctors, nurses, public health administrators, pharmacists, paramedics, dentists and dental hygienists, therapists, psychologists, social workers, counselors, and other mental health professionals. Non-medical hospital personnel—including members of the janitorial, housekeeping, and security staffs—also qualify, as do emergency dispatchers, firefighters, police officers, and active-duty members of the military.

To address the pandemic’s emotional toll on essential workers, Starbucks has also contributed $100,000 to the National Alliance on Mental Illness to be used for virtual mental health services; and the company will give out 50,000 Starbucks care packages and gift cards to frontline workers across the country. While the main goal is to show gratitude to those keeping the nation afloat during an extremely difficult time, Starbucks is also hoping their initiative can be an example for other companies with resources to spare.

“Hopefully other brands will join us in thinking about how [they can] use their platform to again show support,” Virginia Tenpenny, Starbucks's vice president of global social impact, told USA TODAY. “Little deposits in morale can really go a long way, just so that they feel the support from our community.”

It’s not the first time Starbucks has spearheaded a long-term coffee giveaway this year; between March and May, the company handed out more than 2 million free cups of joe to professionals helping the country through the coronavirus pandemic. The Starbucks Foundation has also donated several million dollars to relief funds, food banks, and local organizations.
