Just a year of being overweight drastically reduces the lifelong chances of women surviving cancer, a major study shows.

For every 12 months who have been overweight or overweight as an adult, the risk of dying later in life after being diagnosed with breast or colon cancer increases to four percent.

The link between being overweight and the development of cancer in the first place is well established, but the new study is the first to show how a BMI higher than 25 can also reduce the chances of survival. The World Cancer Research Fund followed the weight of 47,000 women between 20 and 50 years old. Of these, 1,500 started developing breast or colon cancer after the transition.

The Swedish researchers discovered that every year of being overweight, a woman's chance of surviving colon cancer decreased by four percent and breast cancer by three percent.

They said that the time spent on being overweight is "the obesity equivalent of years of cigarette smoking."

Study author Dr. Isabelle Soerjomataram of the International Agency for Research on Cancer said: "Although previous studies have shown a link between being overweight and developing cancer, little is known about how this affects your chances of surviving cancer.

"Our research shows that effective prevention of overweight and obesity must start at a young age."

People who are overweight are more likely to have insulin resistance, chronic inflammation and DNA damage – all related to the onset of cancer.

Excessive body fat gives signals that cells must divide more often and causes damage.

Two-thirds of UK adults are obese or overweight, and obesity has overtaken smoking as the leading cause of four major cancers.

Julia Frater of Cancer Research UK said: "This study reinforces the idea that maintaining and maintaining a healthy weight throughout life can reduce the risk of death from cancer and other diseases.

"It is worth emphasizing that the time that someone was overweight made a big difference in surviving their cancer."

Researchers in the US have achieved a breakthrough in the fight against ovarian and breast cancer by identifying a protein called CD24 that tumor cells use as a signal & # 39; do not eat me & # 39; to prevent the body's immune system from attacking them. If the signal can be blocked, immune cells may attack tumors.
