I was (elected prophylactic bilateral mastectomy) a high risk BC patient and I was presented with biannual (MRI and mammography alternating every 6 months) surveillance as one treatment plan. I chose not to proceed because on a deep dive in medical and biomedical research journals I found that gadolinium (contrast dye used for BC MRI) can be retained by the body; results in diminished kidney function and can result in kidney failure over time; can be retained in bones and joints; and has been found in the brain. I read a research article from 2025 (April or May since time to my initial diagnosis) that presented data accumulated over 13 years from BC patients - this same article evidenced all of the above long term effects from gadolinium contract agents. I was alarmed by the data that in all instances there was a decrease in kidney function (slight to failure) and moreover that the data points to a possible correlation to brain fog, early on-set Alzeheimer's - and with one person in the study developing a brain tumor. I think there were 50 odd women in this long term study. Most everyone reported joint and bone pain too. Apparently I didn't conserve this article because after reading it I said absolutely a no go for me. I will see if I can dig it up - meanwhile I have attached a summary article on gadolinium contrast agents that doesn't contain a lot of jargon. Also, gadolinium contract is known by multiple names - probably due to identify the pharmaceutical company that produced the dye.
