Radiotherapy and Herceptin

I read a post on here from someone whose onc stopped herceptin during rads. Is this normal?

Not for me; everything carrying on as normal. Some Oncies/surgeons also stop Tamoxifen for surgery, but again, mine carried on as normal.

Must be some individual with an individual treatment plan.

I had them together no worries.

Jolly good. Thanks! Just checking as having Herceptin and first rads today - but haven’t seen oncy for over a month so couldn’t check with him…

My Onc stopped Herceptin during Rads, when I asked why I was told it was because my Mx was on the left side so the heart had to be protected and Herceptin puts extra strain on it.
