NEW YORK (Reuters Health) – A new study suggests that a heart attack or stroke can be an early sign of cancer.
The study results showed that the risk of heart attack and stroke had jumped 70% in the year prior to the diagnosis of cancer.
Lung cancer and colon cancer, as well as advanced cancers, seem to be closely related to an increased risk of heart attack and stroke due to arterial thrombosis.
"Our data shows that the risk of seizures and stroke starts to increase in the five months preceding the cancer diagnosis and reach its highest level a month earlier," said lead researcher Babak Navi, a professor associated with Cornell University. "The effects of cancer on the coagulation system are the main cause of these risks."

He explained that the development and diagnosis of cancer can take months and sometimes years, and that some cancers have biological effects on the body, especially with regard to the activity of the blockage of the coagulation.
Researchers looked at the records of 37,433 people aged 76 on average, diagnosed with cancer from 2005 to 2013, and compared them with people who had not been diagnosed with cancer, and then retrospectively tracked seizures. cardiac and stroke in the year preceding the diagnosis.
During the first seven months, there was no difference between the two groups, but the risk of CVD increased in patients diagnosed later.
A month ago, the diagnosis was most likely to have a heart attack or stroke five times.

The study, published in the journal Blood, did not address the severity of heart attacks or strokes. The researchers also acknowledged that their results did not apply to younger patients.
"I do not want to overestimate the absolute risk of cancer to heart attacks, but there is a high risk relationship with immediate clinical effects," said Dr. Navi.
