Breast cancer is the most prevalent cancer among women in Asian countries, particularly in Pakistan, where the incidence of breast cancer is alarmingly high. Although it is a treatable condition, timely diagnosis and proper treatment are crucial for effectively combating this disease.

Symptoms of Breast Cancer

Breast cancer, like any other illness, presents certain clear and common symptoms that indicate its onset.

4. Unusual Discharge:
   • Any discharge from the nipple, particularly if it’s bloody.
5. Hardened Area:
   • Development of a hardened area around the breast or underarm.
6. Changes in Nipple Appearance:

8. Swelling or Soreness:
   • Unexplained swelling or soreness in the breast or underarm.

These symptoms, when noticed, warrant immediate examination by a healthcare professional.

Why and How Breast Cancer Occurs

In our bodies, cells continuously divide based on the body’s needs. If these cells divide more than required, they form a group known as a tumor or lump. Breast cancer occurs when this uncontrolled division and growth happen in the breast tissue.

Several risk factors increase the likelihood of developing breast cancer:

1. Age:
   • The risk increases with age, with women over 40 being more susceptible.
2. Genetics:
   • A family history of breast cancer, especially among first-degree relatives, increases the risk.
3. Reproductive Factors:
   • Early onset of menstruation, late menopause, and late or no pregnancy can contribute.
4. Hormone Replacement Therapy:
   • Long-term use of hormone replacement therapy may elevate the risk.
5. Radiation Exposure:
   • Previous exposure to chest radiation, especially during childhood, is a risk factor.
6. Unhealthy Lifestyle:
   • Factors like obesity, lack of physical activity, and excessive alcohol consumption.

Preventive Measures:

While certain risk factors are beyond control, adopting a healthy lifestyle can reduce the risk of breast cancer:

1. Regular Exercise:
   • Engaging in regular physical activity helps maintain a healthy weight and reduces the risk.
2. Balanced Diet:
   • A diet rich in fruits, vegetables, and whole grains supports overall health.
3. Limiting Alcohol Intake:
   • Moderating alcohol consumption can lower the risk of breast cancer.
4. Breastfeeding:
   • For mothers, breastfeeding may contribute to a reduced risk.
5. Regular Checkups:
   • Regular breast self-exams and routine mammograms are crucial for early detection.
