The free medical exercise, which had support from the Ar-Rahman Foundation and Russia Health Services, was for the organisations to give back to the community.
Mr Solomon Nii Okai, the Greater Accra Chairman of GMM, said it was to take healthcare services to the doorstep of people, especially the less privileged.
Hundreds of people were screened for hypertension, hepatitis B, and diabetes.
Some people were given COVID-19 vaccines and booster doses.
Others also had their breasts screened.
Nii Okai said a similar event would be organised at Nima and other communities soon.
He underscored the need for healthy eating and exercising.
Dr Nabil Nuamah, General Surgery Consultant and Liver Transplant Surgeon at 37 Military Hospital and member of Ar-Rahman Foundation, urged middle-aged women to start screening themselves for breast diseases and cervical cancer while men aged 45 and above should do the same for prostate cancer for early detection and treatment.
