Heritage AIIs Cancer Hereditary? What Your Family History Can Tell You
It is not cancer that is inherited but, in some cases, a predisposition to it. Which patterns in a family history matter and what to do if cancer has affected close relatives.
Also in Russian: the original article
When cancer happens to someone close, almost everyone wonders: what about me? Let’s answer plainly. Cancer itself is not inherited. In some cases, a higher predisposition to it is. Most cases of cancer are not hereditary: genes passed down in a family are commonly estimated to account for roughly 5–10%.
A predisposition is not a diagnosis and not “it will definitely happen”. It means a baseline risk that is above average. And it is worth knowing precisely because then there is something you can do with a doctor: prevention, more frequent check-ups, early detection.
What to look for in a family history
The worrying thing is not an isolated case in old age but a pattern:
- the same type of cancer in several blood relatives;
- illness at an early age, noticeably younger than usual;
- several different tumors in one person;
- rare forms.
If any of these is present, it is a reason to see a doctor, not a reason to panic.
What to do, step by step
- Collect the family history of cancer: who had it, which type, and at what age.
- Show this picture to a doctor.
- If there are grounds, the doctor may refer you to a geneticist, who can assess the risk and discuss whether genetic testing or earlier screening is appropriate. Early detection often makes the biggest difference.
This article does not diagnose and does not replace a consultation. Specifics come from a doctor. But the first step is always the same: to know what happened in the family while there is still someone to ask for the details.
