Cancer Tests That Can Save Your Life
The American Cancer Society (ACS) offers these general screening recommendations for healthy women. If you have certain risk factors or symptoms, work with your doctor, who can create a cancer screening schedule that is right for you. It is important to remember that people of any age can get cancer, but the risk for most cancers increases with age.
The following is advice from ACS on how to watch for common cancers in young and middle-aged women. Since screening tests and exams are the best way to catch cancer early, carefully check to make sure you are getting what you need.
In women, breast cancer is the most common cancer other than skin cancer. It is also one of the leading causes of cancer deaths in women.
The ACS recommends mammogram screenings for breast cancer. Mammograms use 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.
Thanks to widespread screening with Pap smears , cervical cancer has declined over the past 30 years. This type of cancer is usually found in women aged 50 or younger, but it can occur at any age.
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 3 years.
- If you are aged 30-65—It is recommended that you have the Pap test along with the human papillomavirus (HPV) test every 5 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. Normal results include 3 normal results in a row and no abnormal results in the past 10 years.
Ovarian cancer is another common type of cancer affecting the female reproductive organs.
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, abdominal 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).
Endometrial (Uterine) Cancer
Endometrial cancer affects the inner lining of the uterus (called the endometrium).
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, such as vaginal bleeding or spotting, pain in the pelvic area, or 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.
Skin cancer is the most frequent kind of cancer in the US. The vast majority of skin cancers are basal cell or squamous cell carcinoma . Melanoma is a less common type that can be much more deadly.
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, such as 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.
Colorectal cancer affects the colon or the rectum, which are parts of the digestive system.
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.
