Not that people shouldn't still do this, but Breast Cancer is actually far, far less likely for XY-chromosome havers. The same is true for CAIS and faulty SRY intersex women.

I've read conflicting studies on this. Breast cancer doesnt have a single root cause, and several of the genes associated with developing breast cancer can be inherited by people who have a Y chromosome (which has been shown to significantly increase the risk). I believe current guidance after a trans woman has been on HRT for 3 years or more is to treat their risk profile as being equivalent to a cis woman with their genetics and family history.

My mother died of stage 4 breast cancer. So did my great grandmother, and one of my aunts. Consequently I have been getting annual checks on the recommendation of my doctors.

Studies have also shown that family history of breast cancer can and does translate to increased risk for cis men (still comparatively much lower than for cis women, but nontheless still present). Needless to say, if a first degree relation to you has had breast cancer it should be treated as a serious risk regardless of your assigned sex, its just harder to detect early if you have breast tissue. Which is why getting checked is important.
