Skin cancer is the most common cancer, yet a lot of cases come from things we can change. Small habits add up. Use sunscreen the right way, avoid peak sun hours, check your skin regularly, and talk to your doctor if anything looks off. Below are clear, doable steps you can start today.
Wear broad-spectrum sunscreen with at least SPF 30 every time you go outside. That means even on cloudy days and during quick walks. Apply about a shot-glass worth (roughly 30 ml) for your whole body; use a nickel-sized or fingertip amount for your face. Put it on 15 minutes before sun exposure and reapply every two hours—or right after swimming or heavy sweating.
Seek shade between 10 a.m. and 4 p.m. when UV rays are strongest. If shade isn’t available, cover up: long sleeves, long pants, and a wide-brim hat cut your UV exposure a lot. Clothing labeled UPF 30 or higher gives extra protection. Don’t forget sunglasses that block 99–100% of UVA and UVB.
Avoid tanning beds. The devices dramatically raise the risk of melanoma and other skin cancers, especially if used as a teen or young adult. There’s no safe tan from UV lamps—so skip them.
Check your skin once a month. Use a mirror or ask someone to help for hard-to-see spots. Know the ABCDEs of melanoma: Asymmetry, Border irregularity, Color changes, Diameter larger than 6 mm, and Evolving size or shape. Any new bump, sore that won’t heal, or spot that changes should be checked by a clinician.
High-risk factors include fair skin, a history of blistering sunburns, many moles, a family history of melanoma, or a weakened immune system. If you fall into these groups, see a dermatologist for regular exams. For people with a history of many non-melanoma skin cancers, a doctor might suggest daily nicotinamide (vitamin B3) as a preventive option—ask your provider if that applies to you.
Practical tips to make prevention easy: keep sunscreen by the door or in your bag, choose clothing you actually like so you’ll wear it, and set a monthly reminder for a self-skin check. Teach kids good sun habits early—starting young makes a big difference for lifetime risk.
Stopping sun damage now pays off later. These steps cut risk, catch problems early, and are easy to add to daily life. If something about a spot makes you uneasy, get it looked at—early checks save lives.
As a blogger, I have recently come across the fascinating topic of Photodynamic Therapy (PDT) and its role in treating Actinic Keratosis (AK). PDT is a non-invasive treatment that uses light-sensitive drugs and a special light source to destroy abnormal skin cells. It's particularly effective for AK, which is a common precancerous skin condition caused by sun exposure. I was amazed to learn that PDT not only treats AK effectively but also minimizes scarring and reduces the risk of skin cancer. In conclusion, Photodynamic Therapy is a promising and innovative approach to treating Actinic Keratosis and should be considered by those affected by this skin condition.
