Hello and thank you for posting your query on HCM
As you have mentioned that you have had breast cancer
, there is a hereditary condition which increases the incidence of uterine cancer
This is the reason why your doctor adviced you to get an endometrial biopsy
to look for endometrial cancer
The red spots you are having can be a manifestation of an internal malignancy.
A number of cancer cause skin manifestations of this kind.
Don't worry, wait for your biopsy report.
