Prostate cancer is the most common cancer in men in the UK.
It usually develops slowly, so signs and symptoms may not appear for many years.
If the cancer is detected early and does not cause the symptoms, treatment may not be necessary immediately.
Instead, the cancer can only be monitored in case of a risk of spreading.
Treatment can have significant side effects, including erectile dysfunction and that the toilet needs to be used more urgently or more frequently.
For this reason, some men choose to defer treatment until there is a risk that the cancer could spread, according to the NHS.
Some cases will only be diagnosed, when the cancer has already spread.
When prostate cancer is higher, it can not be improved, so treatment works to control symptoms.
Prostate cancer can spread to any part of the body, but it usually spreads to the bones and lymph nodes.
According to Prostate Cancer UK, there is a possibility that exercise can help prevent prostate cancer from spreading to the bone.
The cancer charity has funded a research project to find new ways of preventing cancer from spreading the bones.
In this way researchers at Sheffield University are working to understand the effect of exercise on prostate cancer prevention spreading into the bone.
"There is a good reason to do this: we know that exercise promotes bone formation, while cancer can spread to the bone causing bone damage and weakening," says Prostate Cancer UK.
"Dr Ning Wang, who is leading the project, hopes that the promotion of new cell cell growth, in turn, can prevent cancer cells spreading into the bone."
If the researchers see an impact, they will compare different types of exercise to try to establish a clear link between exercise and prevent the spread of prostate cancer.
It could go on to have a test in men with the disease.
"When prostate cancer spreads, it will be more frequent than going to the bones. This can be painful and extremely difficult to treat," said Dr Wang.
"We know that exercise benefits from bone health, and we believe we can stop cancer cells from establishing a bone camp."
"There is no denial that exercise is good for us but it could be particularly beneficial to the thousands of men diagnosed with prostate cancer every year."
