Dr. Kristi Funk appeared on "The View" to discuss breast cancer prevention, highlighting the significant role of lifestyle factors in cancer incidence and mortality. A recent study published in an American Cancer Society journal indicated that nearly 40% of cancers and approximately 44% of cancer deaths in adults aged 30 and older are linked to modifiable risk factors.
The study identified cigarette smoking as the leading contributor to cancer cases and deaths, accounting for nearly 20% of cancer diagnoses and almost a third of cancer fatalities. Smoking is known to weaken the immune system and damage DNA, increasing the likelihood of cancer development. Furthermore, secondhand smoke exposure is also a recognized risk factor for various cancers.
Excess body weight emerged as another critical factor, with nearly 70% of U.S. adults classified as overweight or obese. The study suggests that excess weight stimulates growth hormones and can lead to inflammation, raising the risk of several cancer types, including breast and colon cancer. A diet rich in fruits, vegetables, and lean proteins, alongside regular exercise, is recommended to mitigate these risks.
Alcohol consumption was also highlighted as a preventable risk factor, contributing to 5% of cancer cases and deaths in the U.S. It is linked to multiple cancers, including those of the throat and liver. Public health organizations emphasize that there are no health benefits associated with alcohol consumption, further underscoring the need for awareness.
Dr. Funk's appearance emphasizes that while not all cancers can be prevented, a significant number can be mitigated through informed lifestyle choices. Individuals are encouraged to take proactive steps to reduce their cancer risk, reinforcing the notion that personal decisions play a vital role in health outcomes.
