My neighbor next door proudly announced her doctor told her she has had her last ever mamo. She seemed ok with it having been told that at her age 70ish, she and clear mammos over the years she would be fine.
I told her that is bunk. Another friend who is in her early 60s had an annual mammo and then the next year a digital and guess what it picked up? A “something” the size of a . yep just that big. Her doctors did a biopsy and you guessed it, it was breast cancer in the earliest stage..a regular mammo would NOT have picked it up but since hers was, a semi radical was done, all margins clear and no lymph nodes in involved and she was given no follow on treatments, given the all clear...Oh the analysis of the tissue showed that this cancer she had was one of the most aggressive forms of breast cancer...
Long story short, I told my neighbor not to buy into that comment by her doctor...it is all about money not the need or safety now due to her age of 74 or whatever it is...
From their study: "Biennial screening after age 69 years yielded some additional mortality reduction in all models, but overdiagnosis increased most substantially at older ages"

If it is true or not I do not know.
