NEW YORK, April 20: Popular cooking oils, such as soybean, sunflower, and corn oil, may increase the risk of an aggressive form of breast cancer, according to one of Britain’s leading cancer experts. The oils contain linoleic acid, which, when exposed to heat, may help cancer cells grow and multiply, says oncologist Professor Justin Stebbing.

In a recent report, Stebbing, who has led major cancer research, highlighted a study that found linoleic acid can overstimulate cell “control centers,” fueling the growth of breast cancer cells. The research, published by Weill Cornell Medicine in New York, focused on how linoleic acid affects the development of triple-negative breast cancer, the deadliest form of the disease.

The study, conducted on mice with triple-negative breast cancer, found that those fed a diet high in linoleic acid developed larger tumors compared to a placebo group. Additionally, the study revealed elevated linoleic acid levels in the blood of humans diagnosed with the same type of cancer.

Triple-negative breast cancer, which accounts for about 15% of all breast cancers, is particularly challenging to treat. It spreads faster than other forms of breast cancer and lacks targeted therapies, as it does not interact with hormones like estrogen. While 85% of women with other breast cancer types survive for more than five years, only 77% of women with triple-negative breast cancer live for five years or more, with survival rates dropping to 12% in advanced stages.

While Professor Stebbing noted the study's significant findings, he stressed that it doesn't suggest a need for a complete avoidance of seed oils but recommends moderation, especially for high-risk individuals. He also encouraged people to maintain a balanced diet rich in fruits and vegetables for overall cancer prevention.

The link between seed oils and cancer growth is not new. Earlier research found that reduced consumption of vegetable oils slowed the growth of prostate cancer in men, while another study indicated that seed oils may promote inflammation, potentially aiding the growth of colon cancer tumors.

Despite the growing evidence, Professor Stebbing emphasized that the findings are just one piece of the puzzle. “A balanced, wholefood diet remains a critical part of cancer prevention,” he said.

While breast cancer remains the most common cancer in the UK, with approximately 56,000 cases diagnosed annually, the study underscores the importance of a healthy diet in mitigating cancer risks. Age, obesity, and alcohol consumption are also significant factors in cancer development.

The NHS continues to face challenges in meeting cancer treatment targets, with only 67% of newly diagnosed patients being referred for urgent treatment within the required time frame.
