Fewer than 10% of all cancer cases are hereditary.
Nobody knows what causes cancer; if we did we’d be a lot closer to preventing and curing it.
With at least one in three people developing cancer, it’s not unusual for several members of the same family to have had cancer.. But unless they all had the same type of cancer it isn’t hereditary – several members of the same side of a family having had the same type of cancer, especially if some developed it at a younger than usual age, is a sign that cancer MAY be hereditary within that family.
You don’t inherit a general tendency to get cancer, and several members of the same family having had different types of cancer isn’t hereditary. In addition (you don’t say how old your step mother and her family members were) cancer diagnosed after the age of 50 is less likely to be hereditary.
My family has a history of cancer, but no history of.hereditary cancer.
Two of my grandparents had cancer. My mum, her sister and her brother died of cancer. My dad had cancer so did my young cousin.
None of these cancers were hereditary and no members of my immediate or extended family have ever been considered at increased risk of developing them.
Of my parents’ 6 children, now aged between 47 and 60, only I have developed cancer and mine too is non-hereditary and unconnected to theirs.
Cancer affects the healthy and the unhealthy alike; it’s not known why, of two people with the same risk factors (or lack of them), one will develop cancer and the other won’t. I’m not aware that there’s any proof or suggestion that certain people are immune to cancer.
In my opinion the greatest risk factors for any cancer are ownership of a body and sheer bad luck
Answering that question would turn you into an instant celebrity. The causes are very illusive, hence the inability of science to come up with a preventive vaccine or a cure-all.
I don’t think anyone knows that. A woman I know, a real health nut, never smoked, lives out in the country in Vermont, got breast cancer. She suspects it must have been something they use in the farm fields up there, but I personally think that someone like her who is always full of fear and worry over what might happen is more likely to get sick in the first place.
Meanwhile, my brother, who smoked cigarettes and pot all his adult life plus also used heroin for a while and drank after he kicked the heroin had all these health problems in his last days, including a big abcess on his lung. With everything coming apart in his body, he had NO cancer, not anywhere. He died of liver disease, but it wasn’t cancer.
