A large-scale public health initiative in Mumbai brought breast cancer pre-screening services to thousands of women across the city in a single day. On July 22, 2026, a total of 33,293 women underwent pre-screening at 298 locations spread across 227 wards. The initiative was organized by the Public Health Department of Brihanmumbai Municipal Corporation, Mumbai, Maharashtra.

The scale of the programme led to recognition by the India Book of Records (IBR) for the maximum number of women pre-screened for breast cancer across multiple locations in a day. Rather than concentrating the activity at one medical facility, the initiative was conducted simultaneously across a large network of locations, allowing women from different parts of Mumbai to participate.

A total of 33,293 women underwent the pre-screening process during the initiative. The activities were distributed across 298 locations covering 227 wards, creating a city-wide screening effort within a single day.

The programme incorporated clinical pre-screening, diagnostic testing and mammography, where applicable. These components were included as part of the broader effort to promote awareness of breast cancer and the importance of early detection.

Breast cancer screening can play an important role in identifying potential concerns at an earlier stage. Through this initiative, the organizers sought to increase public awareness while providing a large number of women with access to breast health assessments across multiple locations.

The multi-location format was a defining aspect of the achievement. Coordinating screening activities across 298 sites and 227 wards required the programme to operate on a city-wide scale, rather than as a single-site campaign. The result was a coordinated public health activity involving tens of thousands of women within one day.

The initiative was also held on the occasion of CM Devendra Fadnavis Ji’s birthday, providing the event with an additional commemorative context. Its primary focus, however, was on breast cancer awareness and early detection through large-scale pre-screening.

With 33,293 women participating across 298 locations in 227 wards, the programme demonstrated the reach that can be achieved through a coordinated, multi-location public health campaign. Clinical pre-screening, diagnostic testing and mammography, where applicable, formed part of the initiative.

The India Book of Records confirmed the achievement on July 22, 2026, recognizing the Public Health Department of Brihanmumbai Municipal Corporation for conducting the maximum number of breast cancer pre-screenings across multiple locations in a single day.
