Depending on where the cancer has spread, the symptoms may vary. But one sign of spreading tumour is pain, according to Cancer Research UK.
The Charity describes the pain as “gnawing” and notes that it can be continuous – the cause being the breaking down of the living tissues that build the skeleton.
The area in the body that can be most affected is the back. The pain in this part of the body can be persistent, says the Charity.
However, according to the UK’s National Health Services (NHS), this backache can also occur when the cancer hasn’t even spread. The health body warns against a worsening pain when eating or lying down.
