Recent statistical data published by the World Health Organisation (WHO) estimates that 23% of cancer-related cases and 14% of cancer-related deaths among women are due to breast cancer. The most effective tool to reduce the burden associated with breast cancer
consists ofearly detection in asymptomatic women via breast cancer screening programs, which commonly use mammography for breast imaging. Breast screening using mammography comprises several steps, which include the detection and analysis of lesions, such as masses and calcifications, that are used in order to estimate the risk that the patient is developing breast cancer.
usually I see "consists of" is followed by at least 2 items/elements/factors, such as "consists of A and B"
"consists of" here is followed by only one item, that is, early detection, Is it idiomatic to use "consists of" this way?
