The prestigious medical journal The New England Journal Of Medicine, published a study claiming breast cancer is being over-diagnosed and the blame can be laid on mammograms.
The head researcher questioned the entire traditional screening process saying that 'screening is a choice, not a public health imperative.'
His reasoning?
According to his data, Dr. Welch concluded that many tumors or lumps found in breast tissue will never transform into metastatic breast cancer.
He claims that tumor size is not as important as biological characteristics which imaging (mammograms included) can never show.
Of course, his opinion has not gone uncontested.
Dr. Daniel Kopans argues that the data is flawed and mammograms are great screening tools. He says that breast cancer increased 1%/year from 1940 to 1980 and that screening is a life-saving procedure for most women.
It's also important to note that Dr. Daniel Kopans receives research grant money from GE Medical, who also happens to make equipment for mammograms... so who should we believe?
