Has anyone had breast cancer radiation causing a new different cancer? I have been told, my doctors have heard of it but none of my physicians or nurses have seen it before. Seems it is rare. When I met the Radiation Oncologist she said she "had heard" of me. Seems my surgeon presented my case at a conference (?), weekly meeting?

In 1999 I was diagnosed with DCIS. Had a lumpectomy with chemo and radiation. This past October I was diagnosed with osteosarcoma caused by the previous radiation. Verified by analysis of tumor. Am currently recovering from mastectomy with LD flap. Need to see oncologist for further analysis/treatment.

hey teltech,

I'm sorry you're going through a second cancer that sucks. Dont know anything about that but it's scary since my MO and rads dr didnt mention anything about that as a potential side effect when we discussed getting rads done.

Diagnosed on 9/27/18 shortly after 34th birthday. ER/PR+, HER2-, 0/2, oncotype 13. Next up rads & tamoxifen

I had rad consults locally and at Mayo before I had rads. The Mayo doc did clearly explain that it was a risk. The local doc never mentioned it. The Mayo doc said it was rare and usually occurs about 20 years out.

My grandmother developed independant breast cancers, one in each breast, a few years apart, that my uncle originally thought was from x-ray exposure...she got a burn from one of the first x-ray machines after a car accident or something like that. Apparently the breast cancer was likely actually genetic though, as I got it at the same age, but she had radiation both times and then later on developed lymphoma. I'm not sure if that had anything to do with the radiation.

My SIL got uterine cancer from tamoxifen, it is rare but it happens. Her doctor really dropped the ball, by the time he listened to her and thought to check it out it was too late. She really suffered with the chemo treatment and the end was not good. I am still angry.

Now thyroid cancer. Definite association between the two. Now fighting to avoid radioactive iodine as then my risk of third primary will be even higher. Or at the very least, will glow in the dark. Ug
