Spot Skin Cancer With Your Smartphone With These 3 Apps
Summer means swimsuits and sunburns, and to prevent that painful peeling and the skin damage accompanying it, sunscreen and/or UV-blocking clothing is absolutely essential. Even if you're not going to be outside for long, cancer-causing skin damage can still occur, and in fact, it can even occur inside if your windows don't have a UV-blocking film. Skin cancer accounts for more diagnoses each year than all other cancers, but the good news is that early detection could be the difference between a simple mole removal or malignant cancer that spreads to other parts of the body. Documenting suspicious marks and moles is important, and the top-notch cameras on our favorite smartphones today make it easy as pie to take them, back them up, and then send them on to your dermatologist. A handful of smartphone apps and devices claim to aid early detection and keep you on track with regular self-exams. These apps can be helpful, but they do have limitations, so it's important to follow conventional wisdom to protect yourself. Here's what you need to know about using your smartphone to detect skin cancer. Read more: What SPF Should You Really Use? Here's What a Dermatologist Says Know the facts about skin cancer Every year, doctors diagnose more than 4 million cases of nonmelanoma (including basal and squamous cell) skin cancers in the US, and the number of melanoma deaths is expected to increase by 4.4 percent in 2023, according to The Skin Cancer Foundation. Basal and squamous cell carcinomas, which develop on the outer layers of the skin, are more common and usually less harmful than melanoma. Melanoma is the deadliest form of skin cancer because it more easily spreads to other bodily systems, becoming metastatic melanoma, and can impact any organ in the body. It originates in the cells responsible for skin pigmentation, called melanocytes. It's an aggressive form of cancer and accounts for nearly 10,000 deaths each year. Even with early detection, it can be fatal. Symptoms of all types of skin cancers include: Change in the size or color of a mole or other spot on the skin A new growth on the skin Odd skin sensations, such as persistent itchiness or tenderness Spread of pigmentation outside the border of a mole Skin cancer may develop due to a variety of factors, including genetics and exposure to toxic chemicals, but the clearest connection is that of skin cancer and UV exposure. How your phone can help you spot skin cancer Telemedicine is a growing field, and skin care is not to be left out: Over the last several years, a handful of skin cancer detection apps have popped up, allowing you to analyze your skin with your smartphone and artificial intelligence algorithms. Some send photos to a dermatologist, some provide instant feedback while others offer helpful reminders about self-checking your skin and scheduling a doctor's appointment. Here are a few you can download on iOS and Android. Miiskin uses hi-res digital photography to capture magnified photos of moles on your skin. Miiskin Miiskin Miiskin uses mole mapping to analyze your skin. Dermatologists perform mole maps as part of a clinical full-body skin exam, using digital dermoscopy (magnified digital photography) to catch suspicious lesions they may not catch with their own eyes. Because they're so high-definition, dermoscopy photos provide much more information than normal digital photos. The developers behind Miiskin wanted to offer a version of this technology to consumers, so they built an app that takes magnified photos of large areas of your skin, for example, your entire leg. According to the website, anyone with an iPhone with iOS 11 and newer or a phone running Android 4.4 and newer can use Miiskin. The app stores your photos separate from your smartphone library and allows you to compare moles over time, which is helpful in detecting changes. Find it: iOS | Android MoleScope With a clip-on camera, MoleScope uses the ABCD method to complete a risk assessment of your moles. MoleScope MoleScope uses magnified images to help people determine whether they should see a dermatologist to get their skin checked. A product of MetaOptima (a supplier of clinical dermatology technology) MoleScope is a device that attaches to your smartphone and sends photos to a dermatologist for an online checkup. Though MoleScope itself won't analyze or diagnose your moles, you can use the ABCD guide in the app to keep tabs on any suspicious moles: The app helps you document your moles with photos and sends them to a dermatologist, who can assess them using the ABCD method: Asymmetry: the shape of one half doesn't match the other the shape of one half doesn't match the other Border: edges are bumpy, ragged or blurred edges are bumpy, ragged or blurred Color: uneven shades of brown, black and tan; odd colors such as red or blue uneven shades of brown, black and tan; odd colors such as red or blue Diameter: a change in size greater than 6 mm Unlike Miiskin, you can only take photos of one mole or small areas with a few moles, rather than large areas like your entire chest or back. Find it: iOS | Android SkinVision SkinVision claims to aid early detection of melanoma. The app uses deep learning to analyze photos of your skin and aid in the early detection of skin cancer. The photos are processed through a machine-learning algorithm that filters image layers based on simple, complex, and more abstract functions and patterns through a technology called convolutional neural network (CNN). SkinVision uses it to check small areas of your skin and come back with a high- or low-risk assessment of that area in less than a minute. SkinVision is backed by a scientific board of dermatologists, but Dr. Daniel Friedmann, a dermatologist at Westlake Dermatology in Austin, Texas, told CNET that even an app with prominent support of scientists has limitations. "I would not recommend that patients avoid these apps, but I would approach their results with cautious skepticism," Dr. Friedmann said, "and counsel patients that suspicious lesions are best evaluated in-office."

SkinVision Read more: 5 Facial Products You'll Want This Summer to Protect Your Skin Research is promising, but accuracy isn't quite there Of all the apps discussed here, SkinVision seems to have the most research behind it. A 2014 study on an older version of SkinVision reported 81% accuracy in detecting melanoma, which at the time researchers said was "insufficient to detect melanoma accurately." However, a more recent study published in the Journal of the European Academy of Dermatology and Venereology determined that SkinVision can detect 95% of skin cancer cases. It's encouraging to see the company continue to work on app accuracy, as early detection of skin cancer is the number-one way to achieve successful treatment. In another study, researchers from the University of Pittsburgh, analyzed four smartphone apps that claim to detect skin cancer. We don't know the exact apps, as they're named only as Application 1, 2, 3 and 4. Three of the apps used algorithms to send immediate feedback about the person's risk of skin cancer, and the fourth app sent the photos to a dermatologist. Unsurprisingly, the researchers found the fourth app to be the most accurate. The other three apps were found to incorrectly categorize a large number of skin lesions, with one missing nearly 30% of melanomas, classifying them as low-risk lesions. A Cochrane review of prior research found that AI-based skin cancer detection has "not yet demonstrated sufficient promise in terms of accuracy, and they are associated with a high likelihood of missing melanomas." To be fair, much of this research took place a few years ago, and the manufacturers may very well have improved their technology since then. More recently, in 2017, a team of researchers at Stanford University announced that their AI does just as well as an in-person dermatologist in detecting skin cancer -- showing that these apps and algorithms do hold promise. Potential benefits of skin cancer detection apps Healthcare professionals have expressed two main arguments related to skin cancer detection apps. The first raises concern that people may rely on apps and consumer devices to assess their risk of skin cancer, which could lead to delayed diagnosis. The second praises these apps for raising awareness among the public and encouraging people to take better care of their skin. Both arguments are valid. In the SkinVision study, for example, the researchers say, "We see the main potential for the smartphone applications in the improvement of the patient-doctor communication by making aware of the need of skin cancer screening and by giving a basis of interaction." Additionally, apps like MoleScope that send images to dermatologists can serve as the first step in receiving a professional exam. All skin cancer biopsies begin with a visual exam, after all. However, you shouldn't use any at-home app or device to replace professional medical care for any condition. Most skin cancer app developers know this and include a disclaimer on their websites that their app is not a replacement for professional healthcare. The importance of annual exams The easiest and most effective way to detect skin cancer is to self-check your skin and go to a dermatologist regularly for a check-up. Experts disagree on what groups of people should get annual exams: Some say you only need a screening if you have suspicious moles or risk factors for melanoma; others say everyone should get an annual skin check. A few factors increase your risk of skin cancer, and if you have any of these, you would benefit from a yearly check-up: Fair skin, light eyes and blonde or red hair Skin that burns or freckles easily A family history of any type of skin cancer History of tanning bed use History of severe sunburns Unusual moles or more than 50 moles on your body For now, even though these apps may be helpful in some ways, your best bet is to seek the professional opinion of a dermatologist or doctor if you notice any suspicious moles or other warning signs of skin cancer. And to wear your sunscreen diligently, with the proper SPF rating, as higher isn't always better.

Your ultimate sunscreen guide: Dermatologist's tips on SPF, PA Ratings and how to apply
The sun's ultraviolet rays can damage your skin even before you realise it. This is why skipping sunscreen is a big no! It is the ultimate weapon against premature aging, hyperpigmentation, sagging skin and skin cancer. The best sunscreen protects your skin from the harmful effects of the sun's ultraviolet rays. Packed with ingredients that either absorb, reflect or scatter UV radiation, it can tackle sunburn and maintain a healthy skin barrier. But the real challenge is to choose a sunscreen that perfectly suits your skin type and needs. As a beginner, searching for a non-greasy, effective sunscreen can be a challenging task. Read this expert-backed guide that simplifies it all for every skin type. Sunscreen is your skin's BFF! They help protect your skin health and prevent sun damage. The best sunscreen for women and men can tackle sunburn, premature aging, dark spots and decrease the risk of skin cancer (The Skin Cancer Foundation). Regular use may even maintain an even skin tone, prevent collagen breakdown and keep your skin youthful over time. Celebrity Dermatologist Dr Meghna Mour, Chief Dermatologist & Hair Transplant Surgeon, Co-founder & Medical Head, Skuccii Supercliniq says, "Even on cloudy days or indoors, UV rays penetrate and cause long-term damage. Think of sunscreen as a daily investment in your skin's future." SPF stands for sun protection factor. It measures how well a sunscreen protects your skin from UVB rays, which are responsible for sunburn and skin damage. SPF is directly related to the amount of solar exposure. As the SPF value increases, sunburn protection also increases (Food and Drug Administration). SPF 30 filters about 97% of UVB rays, while SPF 50 filters about 98%. It's not a linear scale, so going higher than SPF 50 offers a marginal added benefit but no harm, says the expert. But, it is important to note that no SPF blocks 100% of UVB rays. Therefore, it is crucial to reapply the best sunscreen for oily skin every 2-3 hours. A few options for you: While choosing the best sunscreen for dry skin or any other skin type, look for PA+++ and broad-spectrum protection on the label. PA ratings measure protection against UVA rays, which cause premature aging and pigmentation. The more plus signs, the higher the protection. Broad-spectrum means the sunscreen shields you from both UVA and UVB rays, providing complete protection from sunburn, aging, and skin damage. For daily use, always opt for a broad-spectrum sunscreen with at least SPF 30 and PA+++ or higher. Dr Meghna Mour suggests a few ingredients that a sunscreen must have: 1. Zinc oxide/titanium dioxide: These mineral filters sit on the skin's surface, offering gentle, broad-spectrum protection. They are ideal for sensitive, acne-prone, or reactive skin types. 2. Avobenzone: It is a chemical filter that protects against UVA rays. The best sunscreen for combination skin with this ingredient can prevent premature aging and pigmentation. 3. Hyaluronic acid/glycerin: They are humectants that draw moisture into the skin, keeping it hydrated without making it greasy, making it perfect for daily wear under makeup or in humid climates. 4. Niacinamide/vitamin E: These antioxidants soothe inflammation, strengthen the skin barrier, and fight free radical damage caused by sun exposure and environmental stressors. ALSO READ: Neutrogena vs Cetaphil: Choose the best sunscreen for your skin type Here are a few ingredients that a sunscreen should not have, as per the expert: 1. Oxybenzone: This chemical filter is linked to hormone disruption and allergic reactions. Best avoided, especially for children, sensitive skin, or eco-conscious choices. 2. Alcohol denat: Often added for a quick-dry feel, but it can dry out the skin, causing irritation and weakening the skin barrier with regular use. 3. Fragrance: It adds scent but often triggers allergic reactions, redness, or breakouts, especially in sensitive, acne-prone, or compromised skin types. 4. Parabens: Preservatives used for shelf life, but controversial due to concerns about hormone disruption and long-term exposure risks. Many prefer paraben-free options. 5. Cinnamates (e.g., Octinoxate): These are effective UVB filters, but they may irritate sensitive skin and are banned in some regions due to potential environmental impact on coral reefs. Chemical sunscreens absorb UV rays and convert them into heat, which is then released from the skin. They tend to be lightweight, blend easily, and are often invisible on the skin, which makes them ideal for daily use under makeup. Chemical sunscreens are sheer and naturally appearing (Advanced Associates in Dermatology). However, they can irritate sensitive or acne-prone skin and may cause eye stinging. Mineral sunscreens, on the other hand, sit on the skin's surface and physically block or reflect UV rays. With ingredients like zinc oxide and titanium dioxide, mineral sunscreens are gentle on sensitive or reactive skin. They are also reef-safe, which makes them an eco-friendly option. The downside is that they may leave a white cast, though newer formulations address this problem. For sensitive skin, minerals are best (American Academy of Dermatology Association). "For deeper penetration and no white cast, chemical sunscreens work well," says Dr Meghna Mour. A few more options for you: When it comes to the best sunscreen, water-resistant and sweat-proof are often used interchangeably, but they are different. While water-resistant sunscreens are designed to stay effective even when exposed to water, such as swimming or sweating, sweat-proof formulas resist sweating and remain intact on your skin, even during intense physical activity. Water-resistant formulations provide protection for 40 to 80 minutes (American Academy of Dermatology). "Opt for gel-based or water-based sunscreens with a matte finish," says the expert. Look for non-comedogenic and oil-free labels. Make sure to check ingredients like niacinamide and silica that help control excess shine while offering broad-spectrum protection without clogging pores or causing breakouts. "Choose cream-based sunscreens enriched with hydrating ingredients like hyaluronic acid, glycerin, or ceramides," says the expert. These formulas moisturise while shielding your skin from UV damage, preventing further dryness and flakiness throughout the day. Moreover, avoid alcohol-based formulations that may worsen dryness. Go for lightweight, lotion-based sunscreens that balance hydration without feeling greasy. Look for hybrid formulas with both moisturising and oil-control ingredients. A fragrance-free, broad-spectrum SPF 30 or higher works well to protect both dry and oily zones effectively. Mineral sunscreens with zinc oxide or titanium dioxide are ideal for sensitive skin. They offer gentle, broad-spectrum protection without causing irritation. Avoid fragrances, alcohol, and harsh chemical filters like oxybenzone to prevent redness, stinging, or allergic reactions. To keep your skin protected from UV rays, it is essential to apply the sunscreen correctly. The American Academy of Dermatology Association suggests a few tips to help you use it perfectly: 1. Opt for the best sunscreen that comes with an SPF of 30 or higher, is water resistant and provides broad spectrum protection. 2. Apply approximately 1 ounce of sunscreen 15 minutes before stepping out. 3. Make sure to apply sunscreen to your neck, face, ears and other parts that are not covered by clothing. 4. To remain protected, make sure to reapply the sunscreen every two hours and immediately after sweating or swimming.

Dr Meghna Mour busted some common myths about sunscreen: ● Myth: You don't need sunscreen indoors. Truth: UVA rays penetrate glass—protection is still essential. ● Myth: Darker skin tones don't need SPF. Truth: Everyone needs sun protection to prevent pigmentation and skin cancer. ● Myth: One application is enough for the whole day. Truth: Reapplication is necessary every 2–3 hours. ● Choose broad-spectrum protection with SPF 30 or above. ● Match the texture with your skin type. ● Pick non-comedogenic for acne-prone skin. ● Check for PA+++ or higher for strong UVA defense. ● Don't chase trends—pick what suits your skin and lifestyle.

Here's why gel sunscreens are better + 7 best options Protect your skin from sun damage! Best sunscreens for summer for all skin types Apply sunscreen after moisturizer and before makeup. Let it absorb fully. For makeup users, opt for SPF sprays or powder touch-ups during the day. Avoid mixing sunscreen into foundation—it dilutes the efficacy. For daily use, SPF 30 is a good baseline. If you are outdoors for extended periods, swimming, or in harsh sunlight, opt for SPF 50. Reapplication every 2-3 hours is key, especially after sweating or towel-drying. No, up to 80% of UV rays penetrate clouds, so daily sunscreen is still necessary. No, it reduces tanning by blocking UV rays, but some melanin production may still occur with prolonged exposure.

Iowa bill requiring parental consent for minors using tanning beds passed by House
DES MOINES, Iowa — By a vote of 81 to 13, with six lawmakers not voting, Iowa House members voted through a bill requiring parental consent for minors using tanning beds in the state. The bipartisan vote stemmed from the legislative body's concern about increasing cancer rates in the state. 'Iowa, second highest rates of cancer, only state with a growing cancer rate, fifth highest rates of melanoma, 1,600 melanomas per year. We are one of only six states without any restrictions on this issue,' said State Representative Josh Turek (D) District 20, from Council Bluffs. The National Cancer Institute says over half of new cancer among adolescents and young adults is melanoma. The institute also stated that it's the third most common cancer type across 20 to 29-year-old,s as well as 30 to 39-year-olds. Cotton-top tamarin infant at Blank Park Zoo has died The Skin Cancer Foundation says that you have a 75% greater risk of getting melanoma if you use a tanning bed before the age of 35. The bill states that no one in the state under the age of 18 can use a tanning device unless the parent or guardian provides written consent to the tanning facility. There is a written statement that is included into the bill that must be used in the written consent. The bill sponsor told reporters on Monday that a lot of tanning salons already require parental consent for minors to use the equipment. He said that it's for other scenarios where tanning devices are made available. 'The parents will have to be able to walk in and see literature that tells them this is not safe for your kid. The reason you see this coming up, because most of the tanning salons right now, their facilities there are doing it, but it's the facilities that don't do it,' said State Representative Hans Wilz (R) District 25, from Ottumwa. 'People that charge for tanning, whether it's a subscription, whether it's to an apartment, a rental.' The bill now heads over to the Iowa Senate chamber for further consideration.
