Have you known anyone with bone cancer, and what were their symptoms?

My dad.
When the cancer is in the bones, tends to occur in the late stages, stage 4/5. This did paralyze him, unable to walk. (His first site was bowl cancer.)

In young people, red blood cell issues, bone not producing red cells. They get colds easily, their immune system compromised.

(Weight loss, tired, getting colds in summer. Can be an indication.)

Me. I got it in my hip and started having trouble walking. Like I just psychology couldn't make full steps and sometimes my leg would want to lock up completely mid stride
