Mammograms can detect breast cancer early, possibly before it has spread. [6]

Across countries

Mammograms can detect breast cancer early, possibly before it has spread. [6]

Breast cancer occurs in every country of the world in women at any age after puberty but with increasing rates in later life. [1]

In 2024, there were an estimated 2.4 million women diagnosed with breast cancer and 694 000 deaths globally (1). [1]

In countries with a very high Human Development Index (HDI), 1 in 12 women will be diagnosed with breast cancer in their lifetime and 1 in 71 women die of it. [1]

In countries with a low HDI, 1 in 27 women will be diagnosed with breast cancer in their lifetime and 1 in 48 women die from it. [1]

WHO key facts

Breast cancer caused an estimated 694 000 deaths globally in 2024 and was the most common cancer in women in 164 countries out of 186 in the same year. [1]

Approximately 0.5–1% of breast cancers occur in men. [1]

Approximately 80% of breast cancers occur in women with no specific risk factors other than sex and age. [1]

What breast cancer is

Breast cancer is a disease in which abnormal cells in the breast grow out of control and form tumours. [1]

If left unchecked, the tumours can spread throughout the body and become fatal. [1]

Breast cancer cells begin inside the milk ducts and/or the milk-producing lobules of the breast. [1]

Cancer cells can spread into nearby breast tissue (invasion). This creates tumours that cause lumps or thickening. [1]

Invasive cancers can spread to nearby lymph nodes or other organs (metastasize). [1]

Treatment combines surgery, radiation therapy and medications. [1]

The study in Uganda

Despite these ongoing efforts, 70%–80% of breast cancer cases in Uganda continue to be diagnosed at advanced stages, with 5-year survival rates as low as 20% [17, 18]. [9]

Findings highlight that limited breast cancer awareness, misconceptions and sociodemographic disparities significantly affect women’s health-seeking behaviours for breast cancer in Uganda. [9]

What people say

‘Seeing someone survive breast cancer motivates women to seek early care’ (FGD participant). [9]
