Good evening. Since there is a family history of cancer, u may develop cancer in your life. A raised CA 19.9 does not mean you have cancer as it can VBE raised in other conditions also. You need to be on surveillance test on regular basis by endoscopy and regular physical check up. But you need not worry. CA 19.9 has no relation with exercise, but you continue exercises to keep yourself fit and reduce the incidence of other obesity related cancers.
