Skin CancerSkin cancer is one the most common of all cancer types, which occurs when malignant cells are found in the outer layers of your skin. More than 2 million people are diagnosed with skin cancer each year in the United States. Although the incidence of skin cancer continues to rise, most cases could be prevented by limiting the skin's exposure to ultraviolet radiation.

Skin cancers fall into two major categories: melanoma and non-melanoma.

  • Basal cell carcinoma is rarely fatal and most commonly appears after the age of 40 in the form of lesions on the head or neck area, which may increase in size or bleed easily.
  • Squamous cell carcinoma generally develops in people over 50 with sun-damaged skin. This is the most common form of non-melanoma cancer. These growths appear as flat and red, becoming raised, scaly patches.
  • Melanoma is the most severe form of skin cancer, often occurring on the back in men and the legs in women. Risk increases with age, and the average age of detection is between 45-50 years old. It usually appears as a dark flat or raised area on the skin, and is often irregular in shape. Left untreated, melanoma can spread to other parts of the body.

First step: prevention

The good news is that with early detection and treatment, non-melanoma cancers can be cured in over 99% of the cases, and melanoma is readily detectable and usually curable if treated early.

To start protecting your skin, limit sun exposure by seeking shade and always wearing sunscreen, even during the winter months. When possible, wear hats and sunglasses to protect your skin from the sun's harmful rays. UV exposure is one of the biggest contributors to skin cancer, which includes tanning booths. People with fair skin, several moles or freckles, or a family history of skin cancer are also at an increased risk for developing skin cancers.

Early detection and self-exams can save your life

Many types of skin cancer grow slowly, while some melanomas can appear very quickly. Detected in its early stages, skin cancer is very treatable. Use a mirror to examine unreachable parts of your body or ask a family member or friend to assist you. Check your moles regularly for any changes in appearance or sensitivity.

Skin cancer may be one of the most common types of cancer, but it is also one of the most preventable and curable. Take steps now to protect your skin, and visit your dermatologist for regular exams and to have any unusual findings checked.

Summer Sun ProtectionSummer is quickly approaching; will your skin be ready? Keep your skin healthy and beautiful all summer long with these four tips from San Antonio dermatologist Linda J. Banta, MD, PA at Stone Oak Dermatology.
1. Wear Sunscreen
Whether you are heading out for just an hour or the entire day, don't step foot outside of your house without sunscreen. Sunscreen is your skin's first defense against harmful rays, and not only does it help prevent skin cancer, but it can help prevent premature aging and discoloration as well. Choose a high SPF and remember to reapply often, especially if you are swimming or sweating. 
Dr. Banta recommends EltaMD sunscreen. EltaMD has high zinc content, is chemical free, and is cosmetically elegant. It is one of the top sunscreens available, and you will love the way it feels! EltaMD is available at Dr. Banta's office.
2. Seek Out Shade
Even with a quality sunscreen, your skin will need a break from the sun eventually, especially if you will be enjoying the beautiful San Antonio outdoors for an extended period of time or in the middle of the day. Finding a nice, shady spot is a great way to stay cool and protect your skin without risking an extra visit to a dermatologist.
3. Drink Plenty of Water
As summer temperatures soar, keeping your body well hydrated becomes more important than ever. Not only will this keep your skin soft and well-moisturized, but it will also help keep you from dehydrating. Your body needs water to allow you to sweat to help keep you cool. Simply swimming in it isn't enough. You'll need to drink it too.
4. Dress Appropriately
While no one wants to throw on several layers of clothing in the summer, a single light layer in a breathable cotton fabric is a great way to protect your skin from the sun while still keeping cool. Extra long shorts and t-shirts or breezy sundresses and wide-brimmed hats are perfect for enjoying the summer sunshine.
Visit your dermatologist because you want to, not because you need to. Use these four tips all summer long and keep your visits to Dr. Banta at Stone Oak Dermatology in San Antonio fun and stress-free.

While you may have thought about a new haircut or dental veneers, maybe you’re ready to say goodbye to those pesky fine lines and wrinkles.

About Botox

Botox is an injectable made from botulinum toxin, a chemical that causes temporary muscle paralysis and prevents the muscles from contracting. By preventing this muscular movement it also prevents wrinkles from forming. 

While Botox is best known for its cosmetic application it can also be used to treat a host of other problems including hyperhydriosis (excessive sweating), crossed eyes, bladder incontinence, muscle spasms and migraines. Botox has also been tested to see if it can relieve TMJ-related facial pain.

Botox Results

The treatment itself only takes 10 minutes and you can return to your daily activities afterwards. A series of Botox injections will be administered into certain parts of your face, depending on the look you want to achieve. No anesthesia is required and most patients only report feeling a slight pinch when the Botox is injected.

Some people will start to notice their results within the first three to four days; however, you will see the full effect of the treatment in about two weeks. If you are still looking for a smoother appearance after two weeks, talk to your San Antonio dermatologist about additional Botox treatments.

Botox Candidates

The best candidates for this treatment are those who are healthy and have not been diagnosed with a neuromuscular disorder such as multiple sclerosis. Patients should not be pregnant or nursing and all candidates need to be over 18 years old. If you have weak muscles, facial scars or a skin disorder then talk to your San Antonio dermatologist about whether Botox is right for you.

With summer coming, please remember your sun screen.  Sunscreen ingredients are key!  Most sunscreens protect against UVB - but it is the UVA rays that are most damaging and lead to skin cancer and aging.  A lot of sunscreens don't offer broad spectrum UVA protection.  We recommend  medical grade sunscreen Elta MD  - it has the highest amount of zinc oxide - one of the best ingredients for UVA protection.  In addition, EltaMD is cosmetically very elegant, easy to apply and does not feel sticky or leave residue. 

Skin cancer is on the rise - 1 out of 5 will get skin cancer - basal cell and squamous cell.  1 out 0f 50 will get melanoma. Don't be one of them!!! Come in for regular exams.  Yearly exams if you have not had skin cancer.  For those with history of skin cancer, checks every 3 or 6 months depending on type of skin cancer.  Remember skin cancer has a good prognosis if caught early!

skin cancer The month of May is dedicated to melanoma/skin cancer detection and prevention month. During the month of May we want to place an even stronger emphasis on detection and prevention of melanoma and skin cancer.  As your dermatologist in San Antonio, it is important that we provide you with the information you need to further protect your skin from harm.
Do you know the ABC’s of skin cancer detection? To help you better understand detection and prevention, let’s take a look at the ABCDE’s of skin cancer.
Asymmetry: This occurs when one half of your mole does not match the other half. If you draw a line through this mole, the two halves will clearly not match.
Border: The borders of early melanoma are typically uneven. The edges of your mole may be scalloped, blurred, ragged or notched.
Color: Another warning signal is having a mole that contains a variety of colors. This can include a number of different shades of brown, tan or black. Melanoma can also become red, blue or another color, so be on the lookout for a change in color.
Diameter: Melanomas are usually larger in diameter than the size of an eraser on a pencil. However, they can sometimes be smaller when first detected—growing as they progress.
Evolving: Any change in size, shape, color, elevation or another trait is a warning sign of melanoma or another stage of skin cancer. This can also be seen through new symptoms, such as bleeding, itching or crusting.
If you notice any of these ABC’s of skin cancer it is important to visit our dermatologist in San Antonio for further diagnosis, as well as prevention tips. Take charge of your skin this May and protect yourself from melanoma/skin cancer.
