Prostate Cancer

NEXT

The screening methods for prostate cancer include a digital rectal exam, a blood test called PSA (prostate-specific antigen), and a transrectal ultrasound.

During a digital rectal examination, your health-care provider inserts a gloved, lubricated finger into the rectum to examine part of the prostate gland for bumps or hard areas. The PSA test is a blood test that can show an abnormally elevated PSA level, which can indicate prostate cancer. Transrectal ultrasound uses sound waves to make an image of the prostate on a video screen. The most effective and accurate prostate screenings involve tests used in combination, rather than tests used alone. Please discuss which tests are right for you with your doctor.

Age 45 and over

• Men with a family history of prostate cancer and African American men are advised to consider screening beginning at age 45 with a yearly digital rectal exam and PSA blood test.
• Men at general risk for prostate cancer should have a yearly digital rectal exam and PSA blood test beginning at age 50.

Colorectal Cancer

Colorectal cancer affects men and women, most commonly after age 50. Cancerous cells usually develop in a polyp, which is a small tissue mass on the colon’s surface. Detecting and removing polyps early may cure or even prevent colorectal cancer. The three primary methods used to detect colorectal cancer are stool blood testing, flexible sigmoidoscopy, and colonoscopy.

Stool blood testing, in which the stool (bowel movement) is checked for red blood cells not visible to the naked eye, consists of smearing a small amount of stool onto special paper and mailing it to a clinic or laboratory, where a chemical that can detect the presence of blood is applied to the paper. Patients may be asked to follow a special diet four to seven days before the stool blood test.

Sigmoidoscopy consists of having a sigmoidoscope—a flexible tube about three-fourths inch in diameter that contains a special camera —inserted into the anus so the health-care provider can thoroughly examine the lower part of your colon. Because the procedure can cause air to be inserted into the colon, patients may feel some minor discomfort similar to gas pain.

Colonoscopy detects polyps and tumors in their early stages. In this procedure, the entire colon is examined using a flexible tube with an attached camera (colonoscope). If a polyp is found, it can be removed during the exam. If a tumor or large polyp is found, a small piece of tissue will be removed to determine if it is cancer. Before the procedure takes place, the doctor will provide instructions on how to cleanse the colon to prepare for the exam.

Age 50 and over

• Stool blood test every year
• Flexible sigmoidoscopy with digital rectal exam every five years
• Colonoscopy every five to ten years

All ages

Certain groups of people may need special testing because of an increased risk of colorectal cancer. People with one or more of the following should speak with a health-care provider about the need for more specialized colorectal cancer screening:

• Previous diagnosis of colorectal cancer or polyps
• Inflammatory bowel disease such as ulcerative colitis or Crohn's disease
• Two or more immediate relatives such as a parent, sibling, or child with colon cancer
• One or more relatives diagnosed with colorectal cancer before age 50
• Carriers of familial adenomatous polyposis (FAP), Gardner syndrome, or hereditary nonpolyposis colon cancer (HNPCC)

Some leading cancer organizations have recommended stool DNA tests and virtual colonoscopy as options for colon cancer screening. Although both tests have shown promise, HCI recommends continuing with present, thoroughly tested screening approaches until further studies confirm the long-term, overall effectiveness of the newer methods.

Skin Cancer and Melanoma

Skin cancer is the most commonly diagnosed cancer. More than one million cases are diagnosed each year. There are three main types:

Regular screening for skin cancer is important for early diagnosis. Screening for skin cancer consists of skin self-examinations. For skin self-examination, you examine your entire body, checking for irregular moles or lesions.

Suspicious moles may have one or more of the following characteristics:

• Asymmetrical shape
• Border irregularity
• Color difference within a mole
• Diameter equal to or larger than the size of a pencil eraser

Nodules, scaly patches, signs of change or growth in a mole, or any sore that does not heal within four weeks should be reported to a dermatologist. Although the majority of skin abnormalities are not cancerous, they must be evaluated by a dermatologist.

Talk with your dermatologist about when to begin skin exams, how to perform skin self-exams, and how often you need a professional skin exam. Ideally, you would perform a skin self-exam monthly and have a professional skin exam annually.

Those who have any of the following conditions may need special early detection measures, such as more frequent skin exams and mole mapping, and should take more precautions to avoid sunburns:

• A personal history of melanoma
• An immediate family member (parent, sibling, or child) with a history of melanoma
• A light complexion, such as red or blond hair, green or blue eyes, or the tendency to sunburn easily
• A blistering or peeling sunburn that occurred before the age of 18
• One or more abnormal moles, which are moles that are 4 mm or more in diameter, partially or completely flat, varying in color, or have irregular or indistinct borders
