SKIN CANCER

What is skin cancer?

Skin cancer is the most common type of cancer seen in the U.S. and the numbers of people affected are continuing to increase each year. There are three general types of skin cancer.


melanoma.gif MELANOMA, or mole cancer, usually appears as a dark brown spot that slowly increases in size. Usually different shades of brown, blue or black occur within the spot. Melanomas can appear anywhere on the body, but most commonly occur on the back, arms and legs. Melanoma can be very serious as it has the potential to spread internally. However, if detected in the early stages and promptly removed surgically, it can be completely cured. Fortunately, melanoma is the least common type of skin cancer.


Basal cell carcinoma - Knoxville, TennesseeBASAL CELL CARCINOMA is the most common type of skin cancer. These usually occur on the head, neck, back or chest. Basal cell carcinoma can appear in different forms, but most often looks like a small pink or pearly raised bump that later develops an erosion or non-healing sore within its center. This type of skin cancer continues to slowly enlarge and gradually invades deeper and deeper into the skin. However, basal cell carcinomas do not spread internally. They can be easily treated by complete surgical removal.

 

 


Squamous cell carcinoma - Knoxville, TennesseeSQUAMOUS CELL CARCINOMA is the third type of skin cancer. These also occur mostly on the head and neck, but also frequently develop on the hands and arms. Squamous cell carcinoma appears as a rough, warty-like, yellowish, hard growth with a pink edge. With time, the center can erode; causing a sore that bleeds easily. This type of skin cancer only rarely spreads. When it does spread, it is usually confined to local lymph glands beneath the skin. People who get squamous cell carcinoma often have many pre-cancerous rough white small spots on the sun-exposed areas of the hands, arms and face that are called actinic keratoses. Both actinic keratoses and squamous cell carcinoma can be easily treated by complete surgical removal.

What causes skin cancer?

Skin cancer is the result of accumulated skin damage to the skin over long periods of time. People with fair skin and little ability to tan are the most susceptible. People who have worked outdoors for many years or get excessive recreational sun exposure are at higher risk. Having had one skin cancer increased your risk of getting more, including all other types of skin cancer. This risk can be decreased by regularly applying a sunscreen with an SPF of 30 to the constantly sun-exposed areas of the body, such as the face, neck and arms.

A certain percentage of skin cancers will come back, regardless of the type of surgery performed. Therefore, you should return to our office 3-6 months after removal of a skin cancer so that the area can be examined for possible recurrence, as well as to check for new skin cancers in other locations.

Skin Cancer:  The Facts

     Skin cancer is the most common form of cancer in the U.S.  There are over 1 million new cases of skin cancer diagnosed each year; one in five Americans develop skin cancer in a lifetime.  Most skin cancers are curable with early detection and treatment, but if left untreated they can be very dangerous.  Basal cell carcinomas, the most common form of skin cancer, and squamous cell carcinomas, the second most common form, are two non-melanoma forms of cancer.  Melanoma is the most severe form of skin cancer because it can spread to other parts of the body.  Skin lesions are biopsied to verify whether they are cancerous then they can be treated.  There are several treatment options dermatologists will perform to treat skin cancers.  They can scrape the cancerous cells off the healthy tissue, freeze the cells with cryogen, perform Mohs surgery which is a precise and microscopic surgery to remove all the layers of cancerous cells within the tissues or use the Blu-U light to breakdown cancerous cells with several treatments.  It is very important to know your skin and watch for any changes in appearance, such as new growths, changing moles or a sore that won’t heal.  To prevent these different types of skin cancers, it is important to protect your skin from the sun.  Unprotected and repetitive sun exposure, especially starting at young ages, attributes to many skin cancers.  Always wear a sunscreen with SPF 30, such as Blue Lizard, to keep your skin healthy and prevent sun damage. It is recommended that you have a skin exam done regularly by a dermatologist.

NON-SURGICAL therapy for SKIN CANCER - SENSUS SRT-100
Superficial Radiation

What is SRT?
Superficial Radiotherapy (SRT), a low-energy radiotherapy that goes no deeper than the thickness of the skin, is a highly effective, painless and cosmetically attractive alternative to surgery in selected cancers and patient populations.

Why choose SRT?
The SRT-100 treats basal cell and squamous cell skin cancers, especially those requiring difficult or extensive surgery of the head and neck regions - the fold in the nose, eyelids, lips, corner of the mouth, and the lining of the ear - that would otherwise lead to a less than desirable cosmetic outcome.  The  SRT-100 treatment procedure does not require the use of anesthetics.
Experience a safe and proven method to cure your non-melanoma skin cancer.  Utilizing a low does X-Ray beam, the SRT-100 cures basal cell and squamous cell skin cancers without harming healthy surrounding tissue, without pain, without local anesthetics, all in a non-invasive manner.
This leads to outstanding clinical results, with similar outcomes and cure rates as with Mohs surgery, which is the industry gold standard for non-melanoma skin cancer treatment, yet without any scarring, no need for reconstructive surgeries, and without infection risks.  Superficial Radiotherapy is an excellent complementary modality to Mohs surgery, which is excellent for patients over the age of 60, patients with heart disease, diabetes, pacemaker, defibrilator, or patients who are on Coumadin or other blood thinners, putting them at high risk for surgery.  Ask us today about the advantages of the SRT-100.

How does radiation work?
Radiation targets abnormal cells by disrupting cell division; tumor cells divide more rapidly than normal cells making the tumor an easy target for radiation.  Normal cells are able to repair themselves because they are not going through this rapid growth.

Will there be return visits?
The need for surveillance is important for many reasons.  Some cancers have a greater likelihood of recurrence within the first 2 years.  30-50% of patients will develop another non-melanoma skin cancer.

Because the superficial x-rays concentrate radiation dose on the skin surface, the treatment has several advantages over surgical procedures. These advantages include:

  • Virtually painless
  • Very short procedure time
  • Heightened safety
  • No anesthesia requirement
  • Minimal to no scarring
  • Virtually no post-surgical infections
  • Lesser chance for recurrence
  • Faster healing process
  • Virtually no need for reconstruction after procedure
