Caffeine and workouts can help conquer cancer

CAFFEINE and exercise may work together to ward off skin cancer.

An early study found the combination reduced the number of skin tumours in cancer-prone mice by 62pc.

Tumours also shrank by 85pc in treated animals.

And women diagnosed with breast cancer are more likely to survive if they eat up their greens, separate research says.

A large Chinese study found a link between higher consumption of cruciferous vegetables such as cabbage and broccoli, and reduced breast cancer death rates.

Researchers followed the progress of almost 5,000 women for around five years after they were diagnosed.

They found that the more cruciferous vegetables women ate during the first three years after diagnosis, the less likely they were to die.

Breast cancer recurrence risk also decreased, by between 21pc and 35pc.

Treatment

The findings were presented at the American Association for Cancer Research's meeting in Chicago which also heard about the study on caffeine.

Study leader Dr Yao-Ping Lu, from Rutgers Ernest Mario School of Pharmacy in New Jersey, US, said: "We found that this combination treatment can decrease sunlight-caused skin cancer formation in mice.

"I believe we may extrapolate these findings to humans and anticipate that we would benefit from these combination treatments as well."

Mice exercised on a running wheel after being given a dose of caffeine.

Both caffeine and exercise alone produced positive effects, but the benefit was greater when the two were combined.

Mice treated with caffeine alone had 27pc fewer tumours than untreated mice and their cancers were 61pc smaller.

In exercise-only mice, tumour activity decreased by 35pc and tumour volume by 70pc.

Caffeine and exercise also led to a weight reduction of 63pc in mice fed a high fat diet.

Dr Lu believes the common link is inflammation, which dropped as much as 92pc in mice given the combination treatment.
