Skin Cancer

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 superficial forms of 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 several 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 surgerychemotherapy or biologic therapy.

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

  • 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.

Prostate Cancer

Facts About Prostate Cancer

Prostate cancer is the most common cancer in American men.

  • According to the American Cancer Society, about 235,000 men will be diagnosed with prostate cancer in 2006.
  • More than 27,000 men are expected to die of the disease in 2006.
  • One in six men will get prostate cancer in his lifetime. However, only one in 34 men will die of the disease.

Risk Factors For Prostate Cancer

  • Age: The chance of getting prostate cancer goes up as men age. About two-thirds of prostate cancers are found in men over age 65.
  • Race: Prostate cancer is more common among African-American men and Jamaican men of African heritage than in white men.
  • Family history: Men with a father or brother with prostate cancer are more likely to get it themselves.

Screening for Prostate Cancer

  • According to the American Cancer Society, men age 50 or older should be offered a digital rectal exam (DRE) and a blood test to check the level of prostate specific antigen (PSA). African-American men and men with a family history of prostate cancer should be examined beginning at 45.

Diagnosing Prostate Cancer

Prostate cancer is most often found through a blood test measuring the amount of prostate specific antigen (PSA) in the body. Most men diagnosed with prostate cancer have no symptoms and only find their cancer due to screening. However, sometimes prostate cancer can cause symptoms. Some signs to look for include:

  • Feeling that you need to urinate urgently.
  • Having hesitancy when urinating (slow stream).
  • Pain or blood during urination.

If your doctor suspects you might have prostate cancer, some tissue will be taken from your prostate and examined under a microscope. This test is called a biopsy.

Treating Prostate Cancer

If you find out you have cancer, you should discuss your treatment options with a radiation oncologist, a cancer doctor who specializes in treating disease with radiation therapy, and a urologist, a surgeon who specializes in the urinary tract. Options for dealing with prostate cancer include:

  • Surgery.
  • External beam radiation therapy.
  • Prostate brachytherapy.
  • Hormone therapy.
  • Chemotherapy.
  • Cryosurgery.

Sometimes a combination of treatments is best for your cancer, such as surgery followed by external beam radiation. Some men can safely postpone treatment and watch it closely until treatment is needed. This is called watchful waiting.

External Beam Radiation Therapy

External beam radiation therapy (also called radiotherapy) involves a series of daily treatments to accurately deliver radiation to the prostate. There are several ways to deliver external beam radiation.

  • Before treatment, you will have a scan to allow the radiation oncologist to target the radiation on the cancer. Usually several radiation beams are combined to shape, or “conform”, the radiation to the prostate cancer. This technique is called three-dimensional conformal radiation therapy or 3D-CRT. Tailoring each of the radiation beams to accurately focus on the tumor allows doctors to target the prostate cancer while keeping radiation away from nearby organs such as the bladder or rectum.
  • Some doctors use a type of 3D-CRT called intensity modulated radiation therapy or IMRT. IMRT allows doctors to change the intensity of the radiation within each of the radiation beams. In some cases, this lets doctors increase the radiation to the prostate while reducing radiation to nearby normal tissues.
  • In a few clinics in the country, proton beam therapy is used to treat prostate cancer. Proton therapy is a form of external beam radiation that uses protons rather than X-rays to treat cancer cells. Proton therapy is precise like IMRT only it uses a different kind of radiation.

Each of these treatments is acceptable. With all external beam therapy, painless radiation treatments are delivered in a series of daily sessions, each under 30 minutes in duration, Monday through Friday, for six to 10 weeks. The duration of your treatment will depend on your condition and the type of radiation used.

Possible side effects include fatigue, increased frequency or discomfort of urination, and loose bowel movements. These usually go away a few weeks after completing treatments. Impotence is also a possible side effect of any treatment for prostate cancer. However, many patients who receive radiation therapy for prostate cancer are able to maintain sexual function.

Prostate Brachytherapy

Prostate brachytherapy involves treating the cancer by inserting radioactive sources directly into the gland.

  • Permanent seed implants (also called PSI or prostate seed implants) are performed by inserting small metal seeds of radioactive iodine or palladium directly into the gland under anesthesia. The seeds are temporarily radioactive and deliver the radiation to the prostate over several weeks. After losing their radioactivity, the seeds remain in the prostate and are harmless.
  • High-dose-rate prostate implants deliver radiation to the prostate with a few treatments using a single small radioactive iridium source on the end of a computer controlled flexible wire. The radiation is delivered through narrow tubes called catheters inserted into the prostate by your radiation oncologist. You will be under anesthesia and will not feel pain. The tubes remain in place for only one or two days. Once the treatment is complete, the tubes and the radioactive source are taken out. After this type of radiation, you will not need to take special precautions around others.

Depending on your cancer, prostate brachytherapy may be combined with external beam radiation therapy. The side effects from these treatments are similar to those seen with external beam radiation therapy, such as urinary frequency, discomfort on urination or bowel irritation. Medication helps control these symptoms that typically go away within a few months after treatment.

Hormone Therapy

Depending on your cancer, you may benefit from adding hormone therapy to radiation.

  • Works by starving the tumor of the male hormones it needs to grow. This may make your radiation therapy treatments work better.
  • May be used together with radiation therapy or before radiation to shrink the tumor.

The length of time you will receive hormone therapy depends on your cancer. Ask your doctor for more information. Side effects can include hot flashes, mild breast tenderness, diarrhea, nausea and tiredness.
