If many people in your family had cancer, does that increase your chances of getting it?

In brief: Perhaps

Majority of cancers are sporadic ( caused by environmental exposures and some other factors) in nature and not hereditary.
However, if there are a lot of people in your family did have cancer- that would raise a suspicion of hereditary cancer syndrome may be present in the family. You should see a genetician/genetic counsellor to evaluate your cancer risk and further testing that you may need.

In brief: Yes

The incidence of cancer is partly determined by inherited genes and a family history of cancer is an important factor in the susceptibility to cancer. However, the effects of heredity can be modified through preventive measures, e.
g., colonoscopy, low fat-high fiber diet, non-use of tobacco and alcohol etc.

In brief: Probably yes.

Some cancers have a stronger family history than others.
Breast cancer risk is solidly associated with family history, while forms of skin cancer, like squamous or basal cell are not as strongly associated. These are more related to sun exposure. But if there are a lot of people in your family that had cancer, you might want to see your doctor for a work-up to be sure of your own risk.
