Breast cancer is currently the most common malignant tumor in women and a major “killer” of women’s health. Every year, many women lose their lives to breast cancer.

According to the latest statistics, the incidence of breast cancer has become the highest worldwide, with 2.26 million new cases annually, and the incidence rate is on the rise every year, with the disease affecting younger individuals.

The exact cause of breast cancer is still unclear, but its primary cause is believed to be related to endocrine hormones. A family history of gynecological tumors in direct relatives increases the risk of developing breast cancer.

Although early symptoms are not obvious, with careful observation and adequate attention, early signs of breast cancer can still be relatively easy to identify.

8 Early Warning Signs of Breast Cancer

• New lump in the breast or underarm (armpit)
• Thickening or swelling of part of the breast
• Irritation or dimpling of breast skin
• Redness or flaky skin in the nipple area of the breast
• Pulling in of the nipple or pain in the nipple area
• Nipple discharge other than breast milk, including blood
• Any change in the size or the shape of the breast
• Pain in any area of the breast

How can you detect breast cancer early?

The most important screening test to detect breast cancer early is the mammogram. A mammogram is an X-ray of the breast. It can detect breast cancer long before a tumor might be felt by you or your provider. We follow guidelines set by the American College of Radiology and the American Society of Breast Surgeons and recommend that average-risk women age 40 and older receive annual mammograms. Women at higher risk should be screened earlier.

Your risk for breast cancer can change over time, depending on a number of factors. In addition to being female, other risks include:

• Aging
• Inherited genetic mutations, such asBRCA1andBRCA2
• Family history of breast and/or ovarian cancer
• Starting your menstrual cycle before age 12
• Personal history of breast cancer
• Race and ethnicity
• Having dense breasts

Lifestyle factors can also increase your chances of developing breast cancer. These include:

• Never having children
• Giving birth for the first time after age 35
• Using oral contraceptives
• Consuming alcohol
• Being overweight or obese
• Inactivity
• Smoking

Here are 10 practical ways to start lowering your breast cancer risk today.

1. Limit Alcohol Intake

Limiting alcohol to no more than one drink per day can significantly reduce your risk. Research shows that the more alcohol you drink, the greater your risk of developing breast cancer.

2. Maintain a Healthy Weight

Especially after menopause, maintaining a healthy weight is key. After menopause, fat tissue becomes the main source of estrogen, and higher estrogen levels are associated with an increased risk of breast cancer.

3. Stay Active

Physical activity is a powerful tool in cancer prevention. Aim for at least 30 minutes of moderate-intensity exercise, such as brisk walking, five days a week to lower your risk.

4. Limit Sitting Time

Even if you exercise regularly, sitting for long periods can increase the likelihood of developing breast cancer. If you do sit during work, take breaks to stand and move throughout the day.

5. Discuss Hormonal Birth Control

Hormonal birth control can slightly increase breast cancer risk. Discuss the risks and benefits of birth control options with your healthcare provider.

6. Discuss Hormone Replacement Therapy (HRT)

Long-term use of hormone replacement therapy (HRT) has been shown to increase breast cancer risk. However, if you need HRT to manage symptoms, talk to your doctor about finding the lowest effective dose or exploring alternative options.

7. Eat a Healthy Diet

Eating a low-fat diet rich in fruits and vegetables while limiting red and processed meat is another way to protect yourself. Good nutrition can play a role in reducing your overall cancer risk.

8. Quit Smoking

Smoking is a known risk factor for many cancers, including breast cancer. Quitting smoking and avoiding secondhand smoke can significantly lower your risk.

9. Manage Night Shift Work

Some studies suggest that women who work night shifts are at higher risk of developing breast cancer. If reducing night shifts isn't an option, focus on maintaining healthy habits like keeping a sleep routine, engaging in regular exercise, and eating a balanced diet to help mitigate the risks.

10. Talk to Your Doctor About Your Risk

If you have a family history of breast cancer, you may need additional measures to lower your risk. Make sure you’re having open conversations with your healthcare providers about your individual risk factors.
