The ACS recommends the following screening tests for breast cancer:

• Breast self-exam (BSE)—This is an option for women beginning in their 20s. This is a step-by-step examination of your breasts that you do yourself. It is one tool that can be used to help detect changes in your breasts that may or may not be a sign of cancer. You should understand that the self-exam has limits, benefits, and potential harms. You should discuss this with your doctor and decide if doing regular breast self-exams are right for you. In general, you should be familiar with how your breasts look and report any changes or anything abnormal to your doctor.
• Clinical breast exam (CBE)—During this exam, the doctor checks for suspicious lumps or other changes in your breasts. If you are in your 20s or 30s, you should have a CBE at least every three years. If you are aged 40 or older, you should have CBE every year.
• Mammograms—This exam uses low-dose x-rays to make a picture of your breast tissue. The ACS recommends having a mammogram every year starting at age 40. You can continue to have this exam yearly if you are in good health. Due to family history, genetics, or other factors, some women may also want to have an MRI in addition to mammograms. Your doctor can help you decide if additional screening is recommended for you.

The ACS and many other health organizations recommend the following guidelines for cervical cancer screening:

• If you are aged 21-29 years—It is recommended that you have the Pap test every three years.
• If you are aged 30-65—It is recommended that you have the Pap test along with the human papillomavirus (HPV) test every five years. (Or, you can continue to have just the Pap test every three years.)
• If you are aged 65 or older—You may be able to stop having Pap and HPV tests if you have had normal results (eg, three normal results in a row and no abnormal results in the past 10 years).

There are not currently effective tests for early detection of ovarian cancer. You should let your doctor know if you have any symptoms that may be caused by ovarian cancer such as bloating, belly or pelvic pain, feeling full early, or problems urinating. Remember that these symptoms may have other causes than ovarian cancer.

If you are at high risk for ovarian cancer, there are some screening tests that may be used, such as pelvic exams, transvaginal sonography (a type of ultrasound test) and CA-125 blood test (a protein that may be higher in women with ovarian cancer).

ACS recommends that you talk to your doctor about the risks and symptoms of endometrial cancer, especially once you reach menopause (usually around the age of 50). If you have any symptoms (eg, vaginal bleeding or spotting, pain in the pelvic area, pain during urination or intercourse), tell your doctor right away. If you are at high risk for endometrial cancer, after age 35 you may need to have an endometrial biopsy every year.

During your routine physical exam, your doctor will check your skin. If you have any concerns about suspicious moles, talk to your doctor. Some symptoms to look for include changes in the shape (eg, uneven shape or ragged edges), color, or texture of a mole. You can also check your skin once a month. Follow these tips for doing a skin self-exam:

• Use a full-length mirror or hand-held mirror to check hard to spot places, such as between the buttocks or in the genital area.
• Do the exam in a well-lit room.
• Turn from front to back and left to right.
• Note the size, shape, color, and texture of all skin blemishes and moles.
• Check your fingernails, palms, and forearms.
• Check your feet, toenails, soles, and between the toes.
• Examine your scalp, separating the hair with a comb or a blow dryer.

According to the ACS, you should begin screening at age 50. If you have certain risk factors for colorectal cancer, you may need having screening tests started when you are younger. Screening may involve one of the following tests:

• Tests to find polyps and cancer:
  • Flexible sigmoidoscopy (every 5 years)—a visual exam of the rectum and lower portion of the colon
  • Colonoscopy (every 10 years)—a visual exam of the rectum and colon.
  • Double-contrast barium enema (every 5 years)—a test that involves inserting barium (a milky fluid), and then having x-rays done of the intestines
  • CT colonography (every 5 years)—a radiology test that looks at the colon
• Other tests that may be used to find cancer:
  • Fecal occult blood (every year)—a test to detect the presence of blood in the stool
  • Fecal immunochemical test (every year)—another test to detect the presence of blood in the stool
  • Stool DNA test (no specified schedule)—a test to identify DNA markers that may signify the presence of polyps or cancer

While these recommendations are from the ACS, there are many other organizations that provide screening guidelines. The screening tests that your doctor recommends depend on a number of factors, like your age, personal and family medical history, risk factors, and symptoms. You can take an active role in your healthcare by talking to your doctor about the right screening tests for you.
