Family history of cancer - are my husband and children at a higher risk of developing it?

Just looking for some help as getting a bit lost looking online for answers. 
My mother in law was diagnosed with breast cancer aged 34 but was given the all clear after some radiotherapy and had been clear for 12 years before it returned aged 46 and it is now terminal. 

My husband did ask her if she had been tested for any genes to which she said she had and that she didn’t carry a gene and her cancer was hormonal. I’m just still a bit concerned for my husband and our children I think due to the age she caught breast cancer and the fact it returned. Is my husband at a higher risk of developing breast cancer automatically as his mother has it? And same question for my son and daughter? Can my husband still get tested to detect if he has a gene if he wants to?

I have no history of breast cancer on my side of the family but my dad has had prostate and his dad (so my grandad) had bowel cancer so also wondering if my risk is higher for cancer in general because of this? 

many thanks in advance

  • Can’t give any medical knowledge on this just my experience.  In 07 my mum got breast cancer, giving all clear in 08 but it had spread to her brain and she died in 09 at 58.  At the time my two brothers and i asked the doctor if we were more likely to get cancer because our mum had and the doctor said it’s only potentially linked through family if you were to have the same cancer.  My dad died in 21 aged 73 from oesophageal cancer and my brother aged 38 has recently been giving a year to live with terminal lung and stomach cancer.  Maybe not linked but definitely not the best luck!
