At SEMESUR, we join in observing World Breast Cancer Day, highlighting the importance of breast cancer screening programmes and the vital role they play in early detection.

According to the Spanish Association Against Cancer (AECC), breast cancer is the leading cause of cancer-related death among women in Spain, reinforcing the importance of early diagnosis.

WHEN IS WORLD BREAST CANCER DAY?

World Breast Cancer Day is observed every year on 19 October, bringing together individuals, healthcare professionals, organisations, and institutions worldwide in the fight against breast cancer.

The World Health Organization (WHO) established this international awareness day to increase public understanding of the disease and promote the importance of early detection and treatment.

HOW CAN BREAST CANCER BE DETECTED AND PREVENTED?

The AECC highlights the importance of early detection through the following measures:

• Mammography: The most effective screening method for detecting abnormalities, often up to two years before they become palpable.

• Regular breast self-examinations.

• Seeking medical advice if any unusual changes or abnormalities are detected.

• Maintaining a healthy lifestyle, including a balanced diet, regular physical activity, and avoiding a sedentary lifestyle.

WHAT ARE THE SYMPTOMS OF BREAST CANCER?

Symptoms of breast cancer vary from person to person and may differ in severity. Some of the most common signs include:

• Changes in breast size or shape.

• Irregularities in the breast contour.

• Reduced movement of the breast when raising the arms.

• Changes in the skin covering the breast.

• Changes to the nipple, including nipple retraction.

• Swollen lymph nodes in the armpit.

• Fatigue.

• Localised bone pain.

• Breast pain or tenderness on palpation.

BREAST CANCER STATISTICS

According to the European Cancer Information System (ECIS), there were 34,088 new cases of breast cancer diagnosed in Spain in 2020, representing approximately 30% of all cancers diagnosed in women.

The Spanish Association Against Cancer (AECC) states that breast cancer is the most common cancer among women, estimating that one in seven women will develop the disease during their lifetime.

Although the incidence of breast cancer has increased over the years, mortality rates have declined significantly thanks to earlier diagnosis, improved screening programmes, and advances in treatment.

Globally, the GLOBOCAN 2020 study estimated an incidence of 47.5 cases per 100,000 inhabitants. Countries with the highest reported incidence include the United States and Canada, the United Kingdom, Germany, France, and Switzerland, while Spain's incidence is lower and comparable to countries such as Portugal and Ireland.
