In the United States, more than 9,500 people are diagnosed with skin cancer every day. It is currently the most common cause of cancer in the country, and it is often caused by overexposure to ultraviolet rays from the sun. However, there are precautions that you can take to prevent skin cancer, and seeing a dermatologist like Dr. Linda Banta of Stone Oak Dermatology in San Antonio, TX, can help with early detection—read on to learn more.
Skin cancer involves the abnormal growth of skin cells. Such rapid growth leads to the development of tumors, which may be benign or malignant. There are three main types of skin cancer: melanoma, squamous cell carcinoma, and basal cell carcinoma. 95% of all cancers are made up of the latter two types, which are less serious than melanoma. They can also be treated relatively easily. Melanoma, on the other hand, is much more serious and is responsible for 75% of all skin cancer fatalities. Although the number one cause of skin cancer is ultraviolet rays from the sun, UV rays from tanning beds can be just as harmful.
Protecting Yourself in the Sun
When you are choosing a sunscreen, you should take into consideration its SPF (Sunburn Protection Factor). This gives you an indication of how good it is at protecting your skin from ultraviolet B (UVB) rays. You should also choose a broad-spectrum sunscreen that protects against UVB and UVA.
San Antonio residents can further reduce their sun exposure by wearing protective clothing, including shirts that cover your arms, clothing made from protective fabric, wide-brimmed hats, and sunglasses with UV protection.
Skin Cancer Early Detection
Having regular checks for skin cancer is the best way to spot it early on when it is easier to treat. A dermatologist can examine your skin for the early signs of cancer. As well as receiving an annual dermatological check-up, you can also look for signs of skin cancer at home with a self-exam. You should look for moles/birthmarks that have changed over time or are uneven in shape or color. If you notice anything unusual, contact your dermatologist straight away.

With the warmer months just around the corner you may be getting ready to plan some fun in the sun. The summertime always finds children spending hours outside playing, as well as beach-filled family vacations, backyard barbeques, and more days just spent soaking up some much-needed vitamin D.
While it can certainly be great for our emotional and mental well-being to go outside, it’s also important that we are protecting our skin against the harmful effects of the sun’s rays. These are some habits to follow all year long to protect against skin cancer,
Wear Sunscreen Daily
Just because the sun isn’t shining doesn’t mean that your skin isn’t being exposed to the harmful UVA and UVB rays. The sun’s rays have the ability to penetrate through clouds. So it’s important that you generously apply sunscreen to the body and face about 30 minutes before going outside.
Opt for a broad-spectrum sunscreen with an SPF of at least 30 that also protects against both UVA and UVB rays. Everyone should use sunscreen, even infants. Just one sunburn during your lifetime can greatly increase your risk for developing skin cancer, so always remember to lather up!
Reapply Sunscreen Often
If you are planning to be outdoors for a few hours you’ll want to bring your sunscreen with you. After all, one application won’t be enough to protect you all day long. A good rule of the thumb to follow is, reapply sunscreen every two hours. Of course, you’ll also want to apply sunscreen even sooner if you’ve just spent time swimming or if you’ve been sweating a lot (e.g. running a race or playing outdoor sports).
Seek Shade During the Day
While feeling the warm rays of the sun on your shoulders can certainly feel nice, the sun’s rays are at their most powerful and most dangerous during the hours of 10am-4pm. If you plan to be outdoors during these times it’s best to seek shady spots. This means enjoying lunch outside while under a wide awning or sitting on the beach under an umbrella. Even these simple measures can reduce your risk for skin cancer.
See a Dermatologist
Regardless of whether you are fair skinned, have a family history of skin cancer or you don’t have any risk factors, it’s important that everyone visit their dermatologist at least once a year for a comprehensive skin cancer screening. This physical examination will allow our skin doctor to be able to examine every growth and mole from head to toe to look for any early signs of cancer. These screenings can help us catch skin cancer early on when it’s treatable.
Noticing changes in one of your moles? Need to schedule your next annual skin cancer screening? If so, a dermatologist will be able to provide you with the proper care you need to prevent, diagnose and treat both melanoma and non-melanoma skin cancers.
Too much exposure to sunlight can be harmful to your skin. Dangerous ultraviolet B (UVB) and ultraviolet A (UVA) rays damage skin, which leads to premature wrinkles, skin cancer and other skin problems. People with excessive exposure to UV radiation are at greater risk for skin cancer than those who take careful precautions to protect their skin from the sun.
Sun Exposure Linked to Cancer
Sun exposure is the most preventable risk factor for all skin cancers, including melanoma. To limit your exposure to UV rays, follow these easy steps.
- Avoid the mid-day sun, as the sun's rays are most intense during 10 a.m. and 4 p.m. Remember that clouds do not block UV rays.
- Use extra caution near water, snow and sand.
- Avoid tanning beds and sun lamps which emit UVA and UVB rays.
- Wear hats and protective clothing when possible to minimize your body's exposure to the sun.
- Generously apply a broad-spectrum, water-resistant sunscreen with a Sun Protection Factor (SPF) of at least 30 to your exposed skin. Re-apply every two hours and after swimming or sweating.
- Wear sunglasses to protect your eyes and area around your eyes.
Everyone's skin can be affected by UV rays. People with fair skin run a higher risk of sunburns. Aside from skin tone, factors that may increase your risk for sun damage and skin cancer include:
- Previously treated for cancer
- Family history of skin cancer
- Several moles
- Typically burn before tanning
- Blond, red or light brown hair
If you detect unusual moles, spots or changes in your skin, or if your skin easily bleeds, make an appointment with our practice. Changes in your skin may be a sign of skin cancer. With early detection from your dermatologist, skin cancers have a high cure rate and response to treatment. Additionally, if you want to reduce signs of aged skin, seek the advice of your dermatologist for a variety of skin-rejuvenating treatment options.
According to the Skin Cancer Foundation, about 5.4 million new cases of skin cancer are treated in the United States each year. This staggering number shows that taking preventative measures against this disease is more important than ever. Equally as important as preventing skin cancer, however, is knowing the early warning signs of skin cancer as catching this condition early greatly increases its curability rate. Find out more about the signs of skin cancer and what you should do if you notice them with Dr. Linda Banta at Stone Oak Dermatology in San Antonio, TX.
Do I have skin cancer?
Skin cancer also appears on the skin as what looks like a mole. The mole will have certain features if it could be potentially cancerous. Remembering these qualities is easy with the ABCDE method. Potentially cancerous moles can have the following characteristics:
- Border is jagged instead of smooth
- Color of the mole varies instead of remaining one solid color throughout
- Diameter of the mole is more than 6 millimeters
- Evolving mole which changes shape, size, or color
How can I prevent skin cancer?
Preventing skin cancer is as easy as limiting the skin’s exposure to the sun’s harmful UV rays. Always wear a sunblock with at least 30 SPF on areas of the skin exposed to the sun. Try to stay out of the sun at times when it is strongest, usually around noon. Wear tight-knit clothing and a wide-brimmed hat to keep the sun off of your face and neck. In addition to limiting your exposure to the sun, you can further prevent skin cancer with regular skin examinations with your dermatologist.
Skin Examinations in San Antonio, TX
A skin examination gives your dermatologist the chance to give your entire body the once-over, searching for any questionable moles or discolorations. Catching skin cancer early greatly increases the curability rate and allows your doctor to use less complicated and invasive procedures to remove the cancerous cells.

We all want to achieve a healthy tan. It makes us look and feel better, but that bronzed glow may not be as healthy as you think. A tan is your skin’s reaction to ultraviolet (UV) light. This darkening of the skin cells is the skin's natural defense against further damage from UV radiation.
According to the American Academy of Dermatology (AAD), nearly 28 million people tan in the United States annually. Of these, 2.3 million are teens. Many people believe the UV rays of tanning beds are harmless, but this is far from true. Tanning beds emit UVA and usually UVB rays as well. Both UVA and UVB rays can cause long-term skin damage and premature aging (i.e. wrinkles, spots and sagging skin), and can contribute to skin cancer.
The AAD states that the risk of melanoma—the deadliest form of skin cancer—is 75% higher among people who used tanning beds in their teens and 20s. Despite the known risks associated with indoor tanning these numbers continue to increase, as do the incidences of cancer.
Visit your dermatologist immediately if you detect any unusual changes in your skin’s appearance, such as:
- A change or an increase in the size or thickness of a mole or spot
- Change in color or texture of the mole
- Irregularity in the border of a mole
Protecting yourself from UV exposure is the best defense against premature aging and skin cancer. In addition to avoiding indoor tanning beds, you should also always wear sunscreen outdoors to protect your skin from the sun’s damaging rays. Remember to self-examine your own skin as well as have your skin checked regularly by your dermatologist.
Whether you acquire your tan from the beach or a lamp, it’s not safe and it’s not healthy. If you’re a regular tanner, it may be time to rethink your current stance on the standards of beauty. There are safe alternatives to a bronzed glow without risking your health.
