Facts About Skin Cancer
- The skin is the body's largest organ. Its job is to protect internal organs against damage, heat and infection. The skin is also the most exposed organ to sunlight and other forms of harmful ultraviolet rays.
- More than 1 million cases of basal and squamous cell skin cancers will be diagnosed in the United States this year. These cancers can usually be cured.
- 65,000 cases of melanoma will be diagnosed this year. More than 7,000 men and 3,710 women will die from the disease this year.
- Melanoma is 10 times more common among Caucasians than in African-Americans.
Treating Skin Cancer
The treatment you receive depends on several factors, including your overall health, the stage of the disease and whether the cancer has spread to other parts of your body. Treatments are often combined and can include the following:
- Radiation therapy is where the cancer cells are killed by X-rays.
- Surgery is where the cancer cells are cut out and removed.
- Moh's surgery, which is a microscopic surgery, allows surgeons to remove tiny cancerous tissue while preserving healthy tissue.
- Cryosurgery is where the cancer is frozen and removed.
- Laser surgery is where the cancer cells are killed by laser beams.
- Electrodessication is where the cancer is dried with an electric current and removed.
- Chemotherapy is where the cancer cells are attacked by a drug that is either taken internally or applied on the skin.
- Biologic therapy is where doctors help your immune system better fight the cancer.
- Photodynamic therapy is when the cancer is treated with a drug that is very sensitive to a special kind of light. When exposed to that special light, the drug produces a chemical reaction that kills nearby cells.
Types of Skin Cancer
- Basal cell carcinoma: This is the most common form of skin cancer, and it is very curable. These cancers begin in the outer layer of skin (epidermis). Radiation therapy is very effective for treating basal cell cancers that have not spread elsewhere. Other common treatments include surgery, chemotherapy and cryosurgery.
- Squamous cell carcinoma: This is the second most common type of skin cancer. These cancers also begin in the epidermis. Radiation therapy can be used to treat squamous cell cancers that start on the skin and sometimes nearby lymph nodes with or without surgery. Other common treatments include surgery, chemotherapy, cryotherapy and photodynamic therapy.
- Melanoma: This is the most serious skin cancer; it begins in skin cells called melanocytes that produce skin color (melanin). Radiation therapy is used mostly for melanomas that started in another part of the body (metastases). It is used to treat areas where doctors think the disease may spread, such as lymph nodes in the head or neck area.
- Melanoma is usually treated first with surgery and may be followed by chemotherapy, radiation therapy and biologic therapy.
Understanding Radiation Therapy
- Radiation therapy, also called radiotherapy, is the careful use of radiation to treat many different kinds of cancer.
- Cancer doctors, called radiation oncologists, use radiation therapy to try to cure cancer, to control cancer growth or to relieve symptoms such as pain.
- Radiation therapy works within cancer cells by damaging their ability to multiply. When these cells die, the body naturally eliminates them.
- Healthy cells that grow and divide quickly are also harmed by radiation, but they are able to repair themselves in a way that cancer cells cannot.
External Beam Radiation Therapy
External beam radiation therapy may be used to treat skin cancer itself or to relieve pain from cancer that has spread.
- Radiation oncologists deliver external beam radiation therapy to the cancer from a machine outside your body.
- Skin cancer is often treated with a superficial form of radiation called electron beam radiation. That means the radiation only penetrates a short distance below the surface.
- Doctors target the radiation beams at your tumor, giving more radiation to the skin cancer while keeping it away from underlying organs.
- Treatments are usually scheduled every day, Monday through Friday, for approximately four to six weeks to accurately deliver radiation to the cancer.
- Treatments are painless and take less than half an hour each, start to finish.
- Your treatment schedule will depend on your cancer, but it usually requires daily treatments for one or more weeks.
- Radiation therapy is often given in addition to surgery, chemotherapy or biologic therapy.
- Intensity modulated radiation therapy (IMRT) is a form of 3D-CRT that further modifies the radiation by varying the intensity of each radiation beam. This allows a precise adjustment of radiation doses to the tissue within the target area.
- Our Varian TrueBeam system with HyperArc IMRT and volumetric modulated arc therapy (VMAT) technology offers state-of-the-art precision and control, delivering even more highly focused treatments than other locations, that enhance patient safety and outcomes. Our system is the gold standard. It is used in major cancer centers like MD Anderson. Because of this, Premier’s TrueBeam with HyperArc represents the pinnacle of accuracy and effectiveness in radiation therapy today.
Potential Side Effects
The side effects you might feel will depend on the part of your body being treated, the dose of radiation given and whether you also receive other treatments like chemotherapy. Before treatment begins, ask your doctor about possible side effects and how you can best manage them.
- Nearly all patients will experience redness and moistness of the skin, similar to a brisk sunburn. After treatment ends, the skin will form a protective scab and the new, healthy skin will develop underneath it. This healing make take several months.
- You will also likely lose your hair in the area treated. Your hair may grow back, but it might not have the same texture or thickness.
Talk to your doctor or nurse about any discomfort you feel. He or she may be able to provide drugs or other treatments to help.
Caring for Yourself During Treatment
Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry’s standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book. It has survived not only five centuries, but also the leap into electronic typesetting, remaining essentially unchanged. It was popularised in the 1960s with the release of Letraset sheets containing Lorem Ipsum passages, and more recently with desktop publishing software like Aldus PageMaker including versions of Lorem Ipsum.
- Get plenty of rest during treatment.
- Follow your doctor's orders. Ask if you are unsure about anything or if you have questions about your treatments and side effects.
- Tell your doctor about any medications or vitamins you are taking, to make sure if they're safe to use during radiation therapy.
- Eat a balanced diet. If food tastes funny or you're having trouble eating, tell your doctor of dietician. They may be able to help you change the way you eat.
- Treat the skin exposed to radiation with special care. Stay out of the sun, avoid hot or cold packs, and only use lotions and ointments after checking with your doctor or nurse. When cleaning the area, use only water and a mild soap.
- Battling cancer is tough. Don't be afraid to ask friends, family, support groups and your radiation oncology team for help.
