Some of the cancers that most often affect women are breast, colorectal, endometrial, lung, cervical, skin, and ovarian cancers. Knowing about these cancers and what you can do to help prevent them or find them early (when they are small, haven't spread, and might be easier to treat) may help save your life.
Breast cancer is the most common cancer in American women, except for skin cancers. It can occur at any age, but the risk goes up as you get older. Because of certain factors, some women may have a greater chance of having breast cancer than others. But every woman should know about the risks for breast cancer and what they can do to help lower their risk.
Finding breast cancer early – when it’s small, has not spread, and might be easier to treat – can help prevent deaths from the disease. Getting regular screening tests is the most reliable way to find breast cancer early.
The American Cancer Society recommends the following for women at average risk for breast cancer:
Women ages 40 to 44 should have the choice to start yearly breast cancer screening with a mammogram (x-ray of the breast) if they wish to do so.
Women age 45 to 54 should get a mammogram every year.
Women 55 and older can switch to a mammogram every 2 years, or can continue yearly screening.
Screening should continue as long as a woman is in good health and is expected to live at least 10 more years.
All women should understand what to expect when getting a mammogram for breast cancer screening – what the test can and cannot do. They should also be familiar with how their breasts normally look and feel and report any changes to a health care provider right away.
Women at high risk for breast cancer – because of their family history, a genetic mutation, or other risk factors – should be screened with MRI along with a mammogram. Talk with a health care provider about your risk for breast cancer and the best screening plan for you
Colorectal cancer is cancer that starts in the colon or the rectum. Some factors that increase colorectal cancer risk include being overweight or obese, physical inactivity, a diet high in red and processed meats, smoking, heavy alcohol use, being older, and a personal or family history of colorectal cancer or polyps.
Regular colorectal cancer screening is one of the most powerful weapons against colorectal cancer. Most colorectal cancers start with a polyp – a small growth on the lining of the colon or rectum. Screening can help to find colorectal cancer early, when it’s smaller, hasn’t spread, and might be easier to treat. Certain screening tests can also help prevent colorectal cancer by finding and removing polyps before they turn into cancer.
The American Cancer Society recommends the following for people at average risk for colorectal cancer:
Men and women should start regular screening at age 45.
People who are in good health and with a life expectancy of more than 10 years should continue regular colorectal cancer screening through age 75.
For people ages 76 through 85, the decision to be screened should be based on their preferences, life expectancy, overall health, and prior screening history.
People over age 85 should no longer get colorectal cancer screening.
Visual exams of the colon and rectum
If a person chooses to be screened with a test other than colonoscopy, any abnormal test result should be followed up with colonoscopy.
People at high risk of colorectal cancer based on family and/or personal history or other factors may need to: start screening before age 45, be screened more often, or get specific tests. Talk to a health care provider about your risk for colorectal cancer to know when you should start testing.
There are some differences between these tests to consider, but the most important thing is to get screened, no matter which test you choose. Talk to a health care provider about which tests might be good options for you, and to your insurance provider about your coverage
Endometrial cancer is a cancer of the endometrium (the inner lining of the uterus). The risk of endometrial cancer increases as a woman gets older. Things that affect hormone levels, like taking estrogen without progesterone and taking tamoxifen for breast cancer treatment or to lower breast cancer risk can increase a woman’s chance of getting this cancer. Having an early onset of menstrual periods, late menopause, a history of infertility, or not having children can increase the risk, too. Women with a personal or family history of hereditary non-polyposis colorectal cancer (HNPCC or Lynch syndrome) or polycystic ovary syndrome (PCOS), or those who are obese, also have a higher risk for getting endometrial cancer. Women who have had breast cancer or ovarian cancer may also have an increased risk of endometrial cancer.
There are no screening tests or exams to find endometrial cancer early in women who are at average risk and have no symptoms. The American Cancer Society recommends that, at menopause, all women should be told about the risks and symptoms of endometrial cancer. Women should report any unusual discharge, spotting, or vaginal bleeding (that’s getting worse, occurring between periods, or happening after menopause) to a health care provider.
The American Cancer Society also recommends that women who have or are likely to have hereditary non-polyposis colorectal cancer (HNPCC or Lynch syndrome) be offered yearly testing with an endometrial biopsy starting at age 35.
Women should talk to a health care provider about their risk for endometrial cancer and about getting regular pelvic exams. It’s important to know the Pap test is very good at finding cancer of the cervix. Sometimes it can find some early endometrial cancers, but it’s not a test for endometrial cancer.
Lung cancer is most often caused by exposure to chemicals and other particles in the air. While smoking tobacco is the leading cause of lung cancer, not all people with lung cancer smoke. Some might have smoked, and some have never smoked at all.
Not all lung cancers can be prevented. But there are things you can do that might help lower your risk. If you don’t smoke, don’t start, and avoid breathing in other people’s smoke. If you or your loved ones smoke, call the American Cancer Society at 1-800-227-2345 for help quitting.
The American Cancer Society recommends screening for certain people at higher risk for lung cancer. If you smoke now or did smoke, are ages 50 to 80 and in fairly good health, you might benefit from screening for lung cancer with a yearly low-dose CT scan. If you still smoke, talk to a health care provider about your risk for lung cancer, how you can quit smoking, the possible benefits, limits, and harms of lung cancer screening. and where you can get screened.
Chronic infection by certain types of the human papillomavirus (HPV) is the most important risk factor for cervical cancer. You can get HPV through intimate skin-to-skin contact, such as having vaginal, anal, or oral sex with someone who has the virus. Other risk factors for cervical cancer include smoking, having a weakened immune system, having had a chlamydia infection, being overweight, being exposed to or taking certain hormone treatments, and not having regular cervical cancer screening tests.
Avoid smoking and help to protect yourself from HPV by using condoms. The HPV vaccines can protect against certain HPV infections linked to cancer.
The American Cancer Society recommends routine HPV vaccination for girls and boys ages 9 to 12. Children and young adults ages 13 through 26 who haven't been vaccinated, or who haven't gotten all their doses, should get the vaccine as soon as possible. Vaccination at the recommended ages will help prevent more cancers than vaccination at older ages. If you're between the ages of 27 to 45, talk to your doctor to find out if HPV vaccination might benefit you.
Having regular screening tests can help find changes in the cervix that can be treated before they become cancer. The tests for cervical cancer screening are the HPV test and the Pap test. The HPV test looks for infections by types of HPV that can cause precancers and cancers of the cervix. The Pap test looks at the cells taken from the cervix to find changes that might be cancer or precancer. Regular screening can help find cervical cancer early, when it’s small, has not spread, and might be easier to treat.
The American Cancer Society recommends the following for people who have a cervix and are at average risk for cervical cancer:
The most important thing to remember is to get screened regularly, no matter which test you get.
Anyone can get skin cancer, but people with fair skin are more likely to get skin cancer than people with darker skin. Most basal cell and squamous cell skin cancers are caused by repeated and unprotected skin exposure to ultraviolet (UV) rays from sunlight, as well as from man-made sources such as tanning beds. A type of skin cancer called melanoma is less common than some other types of skin cancer, but is more dangerous because it is more likely to grow and spread. People who have had other types of skin cancers and people with a close family member who had melanoma have an increased risk for melanoma.
The most important way to lower your risk of most skin cancers is limiting exposure to UV rays from the sun and other sources like tanning beds. When outside, try to stay in the shade, especially during the middle of the day. If you’re going to be in the sun, wear hats with brims, long-sleeve shirts, sunglasses, and use broad-spectrum sunscreen with an SPF of at least 30 on all exposed skin. If you have children, protect them from the sun and don’t let them get sunburned. Do not use tanning beds or lamps.
Be aware of all moles and spots on your skin, and report any changes to a health care provider right away. You should ask about having a skin exam done during your regular health check-ups.
Although ovarian cancer can occur at any age, it is more likely to occur as women get older. Women who have never had children, or who had their first child after age 35 may be at increased risk for this cancer. Women who have used estrogen alone as hormone replacement therapy are also at increased risk. Women with a personal or family history of hereditary non-polyposis colorectal cancer (HNPCC or Lynch Syndrome), ovarian cancer, or breast cancer are more likely to have a higher risk for ovarian cancer. But women who don’t have any of these conditions or risk factors can still get ovarian cancer.
At this time, there are no recommended cancer screening tests for ovarian cancer for women who are not at high risk of developing the disease. A Pap test does not find ovarian cancer, but a pelvic exam should be part of a woman’s regular health exam. There are also some tests that might be used in women who have symptoms or have a high risk of ovarian cancer. You should see a health care provider right away if you have any of these symptoms for more than a few weeks:
Talk to a health care provider about your risk for ovarian cancer and whether there are tests that may be right for you.
