UV Safety Month: Understanding Skin Cancer Prevention and the Role of Oncology Imaging
July is UV Safety Month, a time dedicated to raising awareness about the effects of ultraviolet (UV) radiation and the importance of protecting skin from sun damage. While many
people associate UV exposure with sunburns and premature skin aging, it is also a significant risk factor for skin cancer.
When discussing skin cancer prevention, oncology imaging is not usually the first thing that comes to mind, and for good reason. Most skin cancers are identified through skin examinations and confirmed through biopsy rather than imaging.
However, for certain types of skin cancer, imaging can become an important part of diagnosis, treatment planning, and ongoing care.
Understanding where prevention ends and where imaging may begin can help patients better appreciate the full continuum of cancer care.
What Is UV Radiation?
Ultraviolet radiation is a form of energy produced by the sun and by certain artificial sources, such as tanning beds.
There are two primary types of UV rays that reach the earth’s surface:
- UVA rays, which contribute to skin aging and long-term skin damage
- UVB rays, which are more closely associated with sunburns and skin cancer development
Over time, excessive UV exposure can damage the DNA within skin cells. This damage may accumulate and increase the risk of developing skin cancer.
Why UV Safety Matters
Skin cancer is the most common type of cancer in the United States. While not every case is caused solely by UV exposure, protecting the skin from excessive ultraviolet radiation remains one of the most effective ways to reduce risk.
Practical UV safety measures include:
- Wearing broad-spectrum sunscreen
- Seeking shade during peak sunlight hours
- Wearing protective clothing and hats
- Using sunglasses that block UV rays
- Avoiding indoor tanning devices
These habits can help reduce cumulative UV damage over time.
How Skin Cancer Is Typically Diagnosed
One important distinction during UV Safety Month is understanding how skin cancer is usually detected. In most cases, skin cancers are first identified through:
- Self-examinations
- Routine skin checks
- Dermatologic evaluations
- Biopsy procedures
If a suspicious mole, lesion, or skin change is found, a healthcare provider may recommend a biopsy to determine whether cancer cells are present.
For many patients, diagnosis occurs before imaging is ever needed.
Common Types of Skin Cancer
The most common forms of skin cancer include:
Basal Cell Carcinoma
Basal cell carcinoma is the most common skin cancer and is often highly treatable when detected early.
Squamous Cell Carcinoma
Squamous cell carcinoma may develop on sun-exposed areas of the body and can sometimes become more aggressive if left untreated.
Melanoma
Melanoma is less common than basal or squamous cell carcinoma but is considered the most serious form of skin cancer because it has a greater potential to spread to other parts of the body.
It is often melanoma that creates the strongest connection to oncology imaging.
When Oncology Imaging May Be Used
For many skin cancers, imaging is not necessary. However, imaging may be recommended when physicians need additional information about the extent of disease.
Depending on the situation, oncology imaging may help:
- Determine whether cancer has spread beyond the skin
- Evaluate lymph nodes
- Assess nearby tissues and organs
- Support treatment planning
- Monitor response to treatment
- Detect potential recurrence
The decision to use imaging depends on factors such as the type of cancer, tumor characteristics, stage of disease, and individual patient circumstances.
Imaging and Melanoma
Advanced melanoma may require additional evaluation beyond a physical examination and biopsy. In some cases, physicians may recommend imaging studies to assess whether cancer has spread to:
- Lymph nodes
- Lungs
- Liver
- Brain
- Other parts of the body
Imaging can provide valuable information that helps guide treatment decisions and supports a more complete understanding of the disease.
Types of Oncology Imaging That May Be Used
Depending on the clinical situation, physicians may use several imaging modalities.
- CT Imaging
- CT scans can help evaluate internal organs and identify areas where cancer may have spread.
MRI
MRI provides detailed images of soft tissues and may be particularly useful when evaluating certain areas of the body, including the brain.
PET/CT Imaging
PET/CT combines functional and anatomical imaging, helping physicians identify areas of increased metabolic activity that may warrant further evaluation.
The type of imaging recommended depends on each patient’s specific diagnosis and treatment needs.
Prevention Remains the First Line of Defense
Although oncology imaging can be an important tool in cancer care, prevention and early detection remain critical. The most effective approach to reducing skin cancer risk often includes:
- Practicing UV safety habits
- Monitoring the skin for changes
- Scheduling regular skin examinations when appropriate
- Seeking medical evaluation for suspicious lesions
The earlier skin cancer is detected, the more treatment options may be available.
Oncology Imaging at ImageCare Radiology
At ImageCare Radiology, advanced oncology imaging services help physicians evaluate, stage, and monitor a variety of cancers. Imaging provides critical information that supports treatment planning and helps healthcare teams make informed clinical decisions throughout the cancer care journey.
A Complete View of Cancer Care
UV Safety Month reminds us that protecting our skin today can help reduce cancer risk in the future. While oncology imaging is not typically used to identify most skin cancers initially, it can play an important role when physicians need to evaluate the extent of disease, guide treatment decisions, or monitor a patient’s progress.
By combining prevention, early detection, and advanced imaging when appropriate, healthcare providers can support patients at every stage of the cancer care continuum.
