WHO warns of rising breast cancer cases due to aging and limited healthcare access

The World Health Organization (WHO) estimates a rise in breast cancer diagnoses and fatalities globally.

Several factors, such as an aging population, shifting lifestyles, and limited access to healthcare services, are responsible for this concerning trend. The journal Nature Medicine published the results.

The International Agency for Research on Cancer (IARC), the cancer agency of the WHO, has predicted that the number of breast cancer diagnoses and deaths will increase globally by 2050.

According to IARC research, around 670,000 women died from breast cancer in 2022, while an estimated 2.3 million women received a diagnosis.

According to the report, breast cancer is the most prevalent malignancy among women worldwide.

According to an IARC estimate, one in 20 women worldwide will receive a diagnosis of the disease at some point in their lives, and over the next 25 years, cases and fatalities will rise by 38% and 68%, respectively.

As per their research, by 2050, there will be 1.1 million annual deaths and 3.2 million new cases globally if current patterns continue.

Breast cancer deaths and diagnoses are expected to rise significantly globally, according to the WHO, with low- and middle-income nations bearing a disproportionate share of the burden.

Changes in reproductive patterns, urbanization, and population expansion are predicted to be the main causes of the increase in breast cancer cases.

Although it is the most prevalent type of cancer among women globally, the burden of breast cancer is not equally distributed.

North America and Western and Northern Europe have the highest incidence rates of breast cancer.

Poorer outcomes result from restricted access to breast cancer screening, diagnostic, and treatment services in many low- and middle-income nations.

According to the study's authors, approximately 25% of breast cancer cases can be avoided; thus, it is critical to recognize these trends and seek to increase global awareness, screening, and treatment choices.

For instance, by cutting back on drinking, keeping a healthy weight, and increasing physical activity.

“Every minute, four women are diagnosed with breast cancer worldwide and one woman dies from the disease, and these statistics are worsening. Countries can mitigate or reverse these trends by adopting primary prevention policies, and by investing in early detection and treatment,” said the IARC scientist Dr Joanne Kim, one of the authors of the report.

Women in their 20s, 30s, and 40s should be aware of four early signs of breast cancer that shouldn’t be ignored.

First, changes in breast size or shape, such as swelling, shrinking, or asymmetry, can be concerning and should be examined by a doctor.

Second, a lump, whether big or small, or a thickened area in the breast or underarm, requires attention, and regular breast self-exams are crucial for detecting such changes.

Third, any changes in the breast or nipple, like redness, dimpling, puckering, or inverted nipples, along with bloody nipple discharge, should not be overlooked.

Finally, persistent breast pain or tenderness can also be a warning sign.
