Results from a recent study concludes that having a heart attack or stroke may indicate an early sign of cancer. The results indicated that the risk of having a heart attack and stroke jumped by 70 per cent in the year before cancer diagnosis.

The researchers discovered that the risk was higher in the month immediately before cancer diagnosis. From the study, lung cancer and colon cancer, appears to be most strongly linked with an increased risk of stroke and heart attack caused by blood clots in the arteries.
Lead author Babak Navi, Associate Professor at Cornell University in the US, said;
“Our data shows there is an associated risk of ischemic stroke and heart attack that starts to increase in the five months before the cancer is officially diagnosed and surges in the month just before diagnosis.”
“These results suggest that cancer’s effect on the clotting system may be what’s mainly driving the associated risk of heart attacks and stroke.”
The research team included 748,662 people who were 67 years and older and examined the risk of heart attack and stroke in those newly diagnosed with lung cancer, breast cancer, bladder cancer, prostate cancer, gastric cancer, uterine cancer, pancreatic cancer, colorectal, and non-Hodgkin lymphoma.
When analyzed separately, both risk of heart attack and stroke showed considerable increase in the months before cancer diagnosis. Cases of heart attack were more common than stroke.
Navi advised that if someone has a heart attack or stroke which are accompanied by weight loss or unexplained anaemia, then a cancer screening should be considered.
