Frequently asked questions
Does cancer pain always mean the cancer is worse?
Not necessarily. Pain can come from treatment, other conditions or nerve irritation as well as the cancer itself. Any new or worsening pain should be reviewed so the cause can be found and treated.
Will I become addicted to strong painkillers?
When strong painkillers are used properly to control cancer pain, addiction is uncommon. The priority is keeping you comfortable. Your team will monitor and adjust treatment to balance relief and side effects.
