Breast Cancer Prevention Foods: What Can You Eat To Reduce Your Chances?

Breast cancer prevention starts with healthy habits — such as limiting the amount of alcohol you drink and staying physically active. Understand what you can do to prevent breast cancer. 

If you're concerned about breast cancer, you may be wondering if there are steps you can take toward breast cancer prevention. Understand the lifestyle factors that may affect your risk of breast cancer and what you can do to stay healthy.

What can I do to reduce my risk of breast cancer?

Breast cancer prevention begins with various factors you can control. For example:

• Limit alcohol. The more alcohol you drink, the greater your risk of developing breast cancer. If you choose to drink alcohol — including beer, wine or liquor — limit yourself to no more than one drink a day.
• Control your weight. Being overweight or obese increases the risk of breast cancer. This is especially true if obesity occurs later in life, particularly after menopause.
• Get plenty of physical activity. Being physically active can help you maintain a healthy weight, which, in turn, helps prevent breast cancer. For most healthy adults, the Department of Health and Human Services recommends at least 150 minutes a week of moderate aerobic activity (think brisk walking or swimming) or 75 minutes of vigorous aerobic activity (such as running), in addition to strength training exercises at least twice a week. If you're just starting a physical activity program, start slowly and build intensity gradually.
• Breast-feed. Breast-feeding may also play a role in breast cancer prevention. The longer you breast-feed, the greater the protective effect.
• Discontinue hormone therapy. Long-term combination hormone therapy increases the risk of breast cancer. If you're taking hormone therapy for menopausal symptoms, ask your doctor about other options. You may be able to manage your symptoms with non-hormonal therapies, such as physical activity. If you decide that the benefits of short-term hormone therapy outweigh the risks, consider using the lowest dose that's effective for your symptoms, and plan to use it only temporarily.
• Avoid exposure to environmental pollution. While further studies are needed, some research suggests a link between breast cancer and exposure to the polycyclic aromatic hydrocarbons found in vehicle exhaust and air pollution.

Can a healthy diet prevent breast cancer?

Research shows that eating a diet rich in fruits and vegetables doesn't offer direct protection from breast cancer. In addition, a recent study of dietary fat and breast cancer showed only a slight decrease in the risk of invasive breast cancer for women who ate a low-fat diet. However, eating a healthy diet may decrease your risk of other diseases, such as diabetes, cardiovascular disease and stroke. A healthy diet can also help you maintain a healthy weight — a key factor in breast cancer prevention.

Is there a link between birth control pills and breast cancer?

Current evidence suggests that use of oral contraceptives doesn't increase the risk of breast cancer. While older research showed a slight increase in risk, those studies included pills with higher estrogen doses than what's available today. In addition, the older research showed that 10 or more years after stopping oral contraceptives, the risk of breast cancer returned to the same level as that of women who never used oral contraceptives.

What else can I do?

Be vigilant about breast cancer detection. If you notice any changes in your breasts, such as a new lump or skin changes, consult your doctor for an evaluation. Also, ask your doctor when to begin mammograms and other screening procedures to detect breast cancer.

Remember, it's not always possible to prevent breast cancer. By practicing healthy habits, however, you're taking an active role in breast cancer prevention.

 

People with shingles show no higher cancer risk

NEW YORK (Reuters Health) - People who come down with shingles seem to have no higher-than-normal risk of developing cancer later on, a study published Monday confirms.

Researchers found that for nearly 36,000 Taiwanese adults with shingles, the chances of developing cancer over the next several years were on par with national statistics.

Shingles - formally known as herpes zoster - is a painful condition caused by a reactivation of the virus that causes chickenpox, which is known as varicella-zoster. Once you have chickenpox, the virus goes into a dormant state and dwells in the body's nerve fibers.

Varicella-zoster most often reactivates in the elderly or people with weakened immune systems, including some cancer patients.

Thus, years ago, doctors thought people with shingles might be at increased risk of having an undiagnosed cancer, or of developing cancer in the future. But research since then has indicated that's not the case.

The new findings, published in the Canadian Medical Association Journal, offer more reassurance.

The study is also one of the first to focus on an Asian population. In Taiwan, people with shingles still undergo more cancer testing than those without the condition, according to Dr. Yi-Tsung Lin, of Taipei Veterans General Hospital.

"Our findings suggest that the extensive cancer survey is not necessary," Lin told Reuters Health in an email.

In the U.S., doctors have already stopped routinely looking for cancer in patients with shingles, according to Dr. Len Lichtenfeld, deputy chief medical officer for the American Cancer Society.

In theory, people with shingles could have an increased cancer risk: If having shingles is a sign that their immune defenses are down, then cancerous cells might be able to slip past the guards too.

And back in the 1970s, Lichtenfeld said, doctors thought people with shingles were more vulnerable to certain cancers. But then studies started to throw that idea into question.

"Now it's generally accepted that we should not be doing an extensive (cancer) workup on patients with shingles," Lichtenfeld said.

The main new piece from this latest study is the fact that it was done in Asia, according to Lichtenfeld - since past research on shingles and cancer has mostly come out of Western countries.

The findings are based on records from 35,871 adults treated for shingles between 2000 and 2008.

During that time, 895 people were also diagnosed with cancer at some point after their shingles diagnosis. That was a bit lower than the number that would be expected in the general population (905 cases).

The findings were similar when Lin's team looked at men and women separately, and at different age groups.

Lichtenfeld said that if people with a history of shingles are concerned about any new symptoms they are having, they should talk to their doctors.

But there's no reason that people newly diagnosed with shingles should be routinely evaluated for cancer - or undergo standard cancer screenings any more often than other people do.

Studies suggest that about 25 percent of people suffer from shingles at some point in their lives. It usually begins with a burning pain or itch in one location on one side of the body, followed by a rash of fluid-filled blisters.

Most shingles cases go away with medication, but occasionally people continue to feel nerve pain for months afterwards.

In 2006, the U.S. Food and Drug Administration approved a vaccine against shingles, made from a weakened form of the chickenpox virus, for adults older than 60.
