My mums had 2 separate breast cancers 1 a lumpectomy the other was a full mastectomy my cousin also died of breast cancer shud I get checked out?

Absolutely! People with a family history of breast cancer are at more risk for having breast cancer themselves. This type of cancer can manifest rapidly and can metastasize very fast. Your doctor will want a baseline exam for you before you have any problems so that when you do, he can compare to the baseline. Don't wait. Go now!
